Finance is about two things:
# Raising capital
# Investing capital
with the objective of increasing the wealth of the shareholders. The role division can be described as:
Treasurer:
* Cash planning
* Bank relation
* Risk
* Insurance
* Dividend policy
Cares about:
 Cash in 
 Cash out
-> $\Large \Delta$ in cash balance.

Controller:
* Budgeting
* Record keeping
* Auditing
* Taxation
* Salary administration
Cares about:
Revenue - 
Costs
-> Profit

How to discriminate different types of business?
|Business|Characteristics|Metric|h
|Electrical Utility|Capital intensive|High Property and Equipment costs|
|Trading Company|Volume driven business|Low fixed assets, low margins, high inventory turnover|
|'Japanese' Company||Long term debt / Owner's equity is the largest of all|
|Supermarket|Very short collection period|Very low account receivable ,Low margins|
|Aero space|Low turnover, High Inventories||
A cash generator is a company that generates more money than they generate:

* Increase dividents
* Service (redeem) outstanding debt
* Invest in new capacity or cost
* Repurchase stock
* Buy growth

!Description
Have you ever watched as one of your competitors raked in profits from customers that you had decided not to bother acquiring? Perhaps this happened because your company based its decision on the traditional method of calculating customer lifetime value (CLV). That could be a costly mistake.

The standard CLV approach calculates the net present value (NPV) of all anticipated cash flows coming in (revenues) and going out (marketing dollars spent) over some time span (months, years, or even decades) for a given customer. Keep customers who show a positive NPV for the marketing investment, the rules say, and drop the ones who don’t. Those are rational choices at the time of the calculation—but only then. The conventional calculation is thus rather static and actually flawed, because you are not able to factor in a company’s flexibility to cut a given customer loose at any time. Flexibility means options, and options have value.

In analyzing the seller’s option to abandon unprofitable customers, my colleagues and I looked at 12 years of purchasing data for more than 100,000 customers of a specialty catalog company. What we found was astonishing: The difference in CLV using the real-options approach versus the traditional approach was, in some cases, as much as 20%. More important, some negative CLVs actually turned positive when the value of the real options was considered. In other words, we found that neglecting a customer with a negative NPV—as traditionally calculated—may be exactly the wrong choice: He could turn out to be highly profitable.

Companies have been using real options for a long time to optimize their investment portfolios. It’s time they applied them in the valuation and management of their investment in customers, too. Here’s a five-step process for bringing real-options analysis into the NPV calculation:

# Estimate the future purchasing behavior (that is, the probability of purchase and dollar amount expected to be spent) for a set of customers, using the common RFM (recency, frequency, and monetary value) approach. This determines expected revenues.
# Calculate costs generated per customer per period.
# Use those two inputs to estimate the profit contribution for each customer over the time horizon under consideration, for example ten periods.
#  For each period, determine whether the expected future profit contribution for that customer might be negative.
# Finally, calculate the CLV that includes the option value (the value of abandoning that customer). What would be saved by dropping him at any given period?

To give a highly simplified example of this fifth step, imagine a customer that cost $100 to acquire and $100 to retain for each subsequent period, thus costing $500 to keep for five periods. If, based on data from previous customers with similar characteristics, that customer might be expected to purchase $150 of goods in the first period, $100 in the next, $50 the next, and $0 in the final two periods, a conventional CLV calculation would show that the customer would be unprofitable (he generates just $300 of revenue at a marketing cost of $500). But, add in the value of the option of dropping him after the second period ($100 × 3 = $300) and the same customer suddenly looks profitable: Over the five periods, the marketing cost is $200 ($500 minus the $300 option to drop) and revenues are $250 ($150 for period 1 and $100 for period 2). In an actual business scenario, this calculation can be mathematically demanding and generally can’t be carried out easily using simple spreadsheet methods. More advanced option-pricing approaches are needed. (For details, see Michael Haenlein, Andreas M. Kaplan, and Detlef Schoder’s “Valuing the Real Option of Abandoning Unprofitable Customers When Calculating Customer Lifetime Value” in the Journal of Marketing, July 2006.)

There’s a saying in business: Anyone can save 50% on marketing expenses, but no one knows which 50%. Including real options in the CLV calculation can actually help direct marketing dollars to the right customers.

In mathematics, a unit vector in a normed vector space is a vector (often a spatial vector) whose length is 1 (the unit length). A unit vector is often denoted by a lowercase letter with a "hat", like this: i-hat (pronounced "i-hat").

In Euclidean space, the dot product of two unit vectors is simply the cosine of the angle between them. This follows from the formula for the dot product, since the lengths are both 1.

The normalized vector or versor $\Large \hat{u}$ of a non-zero vector u is the unit vector codirectional with u, i.e.,

$\Large \hat{u}$ = $\LARGE \frac{u}{\|u\|}$

where vector u between two pairs of vertical lines is the norm (or length) of vector u. The term normalized vector is sometimes used as a synonym for unit vector.

The elements of a basis are usually chosen to be unit vectors. Every vector in the space may be written as a linear combination of unit vectors. The most commonly encountered bases are Cartesian, polar, and spherical coordinates. Each uses different unit vectors according to the symmetry of the coordinate system. Since these systems are encountered in so many different contexts, it is not uncommon to encounter different naming conventions than those used here.

The book rate of return is income divided by assets:

''Book rate of return'' = $\LARGE \frac {book income}{book assets}$
A cash absorber is a company that needs more money than they generate. Possible measures:
* Sell new equity
* Increase financial leverae
* Reduce divident pay out ratio
* Prun (marginal) product lines
* Reduce growth in sales
* Look for a partner
* Be acquired (by a cash cow)
* Or go bankrupt

!Description
With trillions of dollars in cash sitting on their balance sheets, corporations have never had so much money. How executives choose to invest that massive amount of capital will drive corporate strategies and determine their companies’ competitiveness for the next decade and beyond. And in the short term, today’s capital budgeting decisions will influence the developed world’s chronic unemployment situation and tepid economic recovery.

To estimate their cost of equity, about 90% of the respondents use the capital asset pricing model [[CAPM|Portfolio Theory and the Capital Asset Pricing Model]], which quantifies the return required by an investment on the basis of the associated risk.

But that is where the consensus ends. Finance professionals differ in opinion on the underlying assumptions for 6 basic metrics:
# The Investment Time Horizon
# The Cost of Debt
# The Risk-Free Rate
# The Equity Market Premium
# The Risk of the Company Stock ([[Beta]])
# The Debt-to-Equity Ratio
# Project Risk Adjustment
!The Investment Time Horizon
The miscalculations begin with the forecast periods. Of the AFP survey respondents, 46% estimate an investment’s cash flows over five years, 40% use either a 10- or a 15-year horizon, and the rest select a different trajectory.
<<image /static/files/Finance/R1207L_A.gif width:300>>

Some differences are to be expected, of course. A pharmaceutical company evaluates an investment in a drug over the expected life of the patent, whereas a software producer uses a much shorter time horizon for its products. In fact, the horizon used within a given company should vary according to the type of project, but we have found that companies tend to use a standard, not a project-specific, time period. In theory, the problem can be mitigated by using the appropriate terminal value: the number ascribed to cash flows beyond the forecast horizon. In practice, the inconsistencies with terminal values are much more egregious than the inconsistencies in investment time horizons, as we will discuss. (See the sidebar [[How to Calculate Terminal Value]])

!The Cost of Debt
Having projected an investment’s expected cash flows, a company’s managers must next estimate a rate at which to discount them. This rate is based on the company’s cost of capital, which is the weighted average of the company’s cost of debt and its cost of equity, the [[WACC]].

Estimating the cost of debt should be a no-brainer.But people have different ways of applying a tax rate which can have major implications for the calculated cost of capital. The median effective tax rate for companies on the S&P 500 is 22%, a full 13 percentage points below most companies’ marginal tax rate, typically near 35%. (See the [[The Consequences of Misidentifying the Cost of Capital]])

<<image /static/files/Finance/R1207L_B.gif width:300>>

!The Risk-Free Rate
Errors really begin to multiply as you calculate the [[Cost of Equity]]. Most managers start with the return that an equity investor would demand on a [[risk-free|Risk free rate of return]] investment. What is the best proxy for such an investment? Most investors, managers, and analysts use U.S. Treasury rates as the benchmark. But that’s apparently all they agree on.
* 46% of our survey participants use the 10-year rate,
* 12% go for the five-year rate,
* 11% prefer the 30-year bond
* 16% use the three-month rate.
<<image /static/files/Finance/R1207L_C.gif>>

The variation is dramatic. When this article was drafted, the 90-day Treasury note yielded 0.05%, the 10-year note yielded 2.25%, and the 30-year yield was more than 100 basis points higher than the 10-year rate.

In other words, two companies in similar businesses might well estimate very different costs of equity purely because they don’t choose the same U.S. Treasury rates, not because of any essential difference in their businesses.

!The Equity Market Premium
The next component in a company’s [[weighted-average cost of capital|WACC]] is the risk premium for equity market exposure, over and above the risk-free return. In theory, the market-risk premium should be the same at any given moment for all investors. That’s because it’s an estimate of how much extra return, over the risk-free rate, investors expect will justify putting money in the stock market as a whole.

The estimates, however, are varied.
* About half the companies in the AFP survey use a risk premium between 5% and 6%
* Some use one lower than 3%,
* Others go with a premium greater than 7%

<<image /static/files/Finance/R1207L_D.gif>>

A huge range of more than 4 percentage points. We have found that companies tend to use a standard, not a project-specific, time period. In theory, the problem can be mitigated by using the appropriate terminal value: the number ascribed to cash flows beyond the forecast horizon. In practice, the inconsistencies with terminal values are much more egregious than the inconsistencies in investment time horizons, as we will discuss. (See [[How to calculate terminal value]])
!The Risk of the Company Stock
The final step in calculating a company’s cost of equity is to quantify the [[Beta]], a number that reflects the volatility of the firm’s stock relative to the market. A [[Beta]] greater than 1.0 reflects a company with greater-than-average volatility; a [[Beta]] less than 1.0 corresponds to below-average volatility. Most financial executives understand the concept of [[Beta]], but they can’t agree on the time period over which it should be measured:
* 41% look at it over a five-year period
* 29% at one year
* 15% go for three years
* 13% for two.
<<image /static/files/Finance/R1207L_E.gif>>
Reflecting on the impact of the market meltdown in late 2008 and the corresponding spike in volatility, you see that the measurement period significantly influences the [[Beta]] calculation and, thereby, the final estimate of the cost of equity. For the typical S&P 500 company, these approaches to calculating [[Beta]] show a variance of 0.25, implying that the cost of capital could be misestimated by about 1.5%, on average, owing to [[Beta]] alone. For sectors, such as financials, that were most affected by the 2008 meltdown, the discrepancies in [[Beta]] are much larger and often approach 1.0, implying [[Beta]]-induced errors in the cost of capital that could be as high as 6%.

!The Debt-to-Equity Ratio
The next step is to estimate the relative proportions of debt and equity that are appropriate to finance a project. Managers are pretty evenly divided among four different ratios: 
* Current book debt to equity (30% of respondents);
* Targeted book debt to equity (28%)
* Current market debt to equity (23%)
* Current book debt to current market equity (19%).
<<image /static/files/Finance/R1207L_F.gif>>
Because book values of equity are far removed from their market values, 10-fold differences between debt-to-equity ratios calculated from book and market values are actually typical.
!Project Risk Adjustment
Finally, after determining the [[weighted-average cost of capital|WACC], which apparently no two companies do the same way, corporate executives need to adjust it to account for the specific risk profile of a given investment or acquisition opportunity.

* Nearly 70% do
** half of those correctly look at companies with a business risk that is comparable to the project or acquisition target.
* Many companies don’t undertake any such analysis
** instead they simply add a percentage point or more to the rate. An arbitrary adjustment of this kind leaves these companies open to the peril of overinvesting in risky projects (if the adjustment is not high enough) or of passing up good projects (if the adjustment is too high). 
*  37% of companies surveyed by the AFP made no adjustment at all: They used their company’s own cost of capital to quantify the potential returns on an acquisition or a project with a risk profile different from that of their core business.

!Conclusion
Disparities in assumptions profoundly influence how efficiently capital is deployed in the US economy.

The sustainable growth rate is the maximum growth rate, measured in sales, that a company can afford without adding extra external capital. The formula is:

SG = $\Large \frac{R * {Return\ on\ Equity}}{1 - r*{Return\ on\ Equity}}$

Where 
{{{R = Retention rate = 1 - Dividend payout rate}}}

If the actual growth rate is bigger than the sustainable growth rate: [[Cash Absorber]]
If the actual growth rate is smaller than sustainable growth rate: [[Cash Generator]]

Time-Driven Activity-Based Costing was introduced by Robert Kaplan and Steven Anderson to compensate the disadvantages of [[Activity based costing]].

This is a new approach to avoid the difficulties associated with large-scale ABC implementation (HBR November 2004). In this revised model, managers estimate the resource demands of each transaction, product, or customer, rather than relying on time-consuming and costly employee surveys. The Time-Driven Activity-Based Costing method is simpler since it requires, for each group of resources, estimates of only two parameters. 1. What are the costs per time unit of capacity to supply resources to the business activities? (The total overhead expenditure of a department divided by the total employee time available). 2. An estimation of the unit times of activities: how much time it takes to carry out one unit of each kind of activity (as estimated or observed by the manager). This Time-Driven ABC approach also overcomes a serious technical problem associated with employee surveys: employees invariably report percentages that add up to 100, when they are asked to estimate time spent on activities. Managers should take into account time that is idle or unused. The method also supports time equations, a feature that enables the ABC model to approximate the complexity of real-world operations. By showing how specific order, customer, and activity characteristics cause variation in processing time

The general form is //fieldname//'':''//textToSearch// (e."+"g. {{{title:intro}}}). In addition one-character shortcuts are also supported for the standard field"+"s {{{title}}}, {{{text}}} and {{{tags}}}:\n|!What you want|!What you type|!Example|\n|Search ''titles "+"only''|start word with ''!''|{{{!jonny}}} (shortcut for {{{title:jonny}}})|\n|Search ''contents/text "+"only''|start word with ''%''|{{{%football}}} (shortcut for {{{text:football}}})|\n|Search ''tags only"+"''|start word with ''#''|{{{#Plugin}}} (shortcut for {{{tags:Plugin}}})|\n\nUsing this feature you may"+" also search the extended fields (\"Metadata\") introduced with TiddlyWiki 2.1, e.g. use {{{priority:1"+"}}} to find all tiddlers with the priority field set to \"1\".\n\nYou may search a word in more than one"+" field. E.g. {{{!#Plugin}}} (or {{{title:tags:Plugin}}} in the \"long form\") finds tiddlers containin"+"g \"Plugin\" either in the title or in the tags (but does not look for \"Plugin\" in the text). \n\n!Boole"+"an Search\nThe Boolean Search is useful when searching for multiple words.\n|!What you want|!What you "+"type|!Example|\n|''All words'' must exist|List of words|{{{jonny jeremy}}} (or {{{jonny and jeremy}}}"+")|\n|''At least one word'' must exist|Separate words by ''or''|{{{jonny or jeremy}}}|\n|A word ''must "+"not exist''|Start word with ''-''|{{{-jonny}}} (or {{{not jonny}}})|\n\n''Note:'' When you specify two"+" words, separated with a space, YourSearch finds all tiddlers that contain both words, but not neces"+"sarily next to each other. If you want to find a sequence of word, e.g. '{{{John Brown}}}', you need"+" to put the words into quotes. I.e. you type: {{{\"john brown\"}}}.\n\nUsing parenthesis you may change "+"the default \"left to right\" evaluation of the boolean search. E.g. {{{not (jonny or jeremy)}}} finds"+" all tiddlers that contain neither \"jonny\" nor \"jeremy. In contrast to this {{{not jonny or jeremy}}"+"} (i.e. without parenthesis) finds all tiddlers that either don't contain \"jonny\" or that contain \"j"+"eremy\".\n\n!'Exact Word' Search\nBy default a search result all matches that 'contain' the searched tex"+"t. E.g. if you search for {{{Task}}} you will get all tiddlers containing 'Task', but also '~Complet"+"edTask', '~TaskForce' etc.\n\nIf you only want to get the tiddlers that contain 'exactly the word' you"+" need to prefix it with a '='. E.g. typing '=Task' will find the tiddlers that contain the word 'Tas"+"k', ignoring words that just contain 'Task' as a substring.\n\n!~CaseSensitiveSearch and ~RegExpSearch"+"\nThe standard search options ~CaseSensitiveSearch and ~RegExpSearch are fully supported by YourSearc"+"h. However when ''~RegExpSearch'' is on Filtered and Boolean Search are disabled.\n\nIn addition you m"+"ay do a \"regular expression\" search even with the ''~RegExpSearch'' set to false by directly enterin"+"g the regular expression into the search field, framed with {{{/.../}}}. \n\nExample: {{{/m[ae][iy]er/"+"}}} will find all tiddlers that contain either \"maier\", \"mayer\", \"meier\" or \"meyer\".\n\n!~JavaScript E"+"xpression Filtering\nIf you are familiar with JavaScript programming and know some TiddlyWiki interna"+"ls you may also use JavaScript expression for the search. Just enter a JavaScript boolean expression"+" into the search field, framed with {{{ { ... } }}}. In the code refer to the variable tiddler and e"+"valuate to {{{true}}} when the given tiddler should be included in the result. \n\nExample: {{{ { tidd"+"ler.modified > new Date(\"Jul 4, 2005\")} }}} returns all tiddler modified after July 4th, 2005.\n\n!Com"+"bined Search\nYou are free to combine the various search options. \n\n''Examples''\n|!What you type|!Res"+"ult|\n|{{{!jonny !jeremy -%football}}}|all tiddlers with both {{{jonny}}} and {{{jeremy}}} in its tit"+"les, but no {{{football}}} in content.|\n|{{{#=Task}}}|All tiddlers tagged with 'Task' (the exact wor"+"d). Tags named '~CompletedTask', '~TaskForce' etc. are not considered.|\n\n!Access Keys\nYou are encour"+"aged to use the access keys (also called \"shortcut\" keys) for the most frequently used operations. F"+"or quick reference these shortcuts are also mentioned in the tooltip for the various buttons etc.\n\n|"+"!Key|!Operation|\n|{{{Alt-F}}}|''The most important keystroke'': It moves the cursor to the search in"+"put field so you can directly start typing your query. Pressing {{{Alt-F}}} will also display the pr"+"evious search result. This way you can quickly display multiple tiddlers using \"Press {{{Alt-F}}}. S"+"elect tiddler.\" sequences.|\n|{{{ESC}}}|Closes the [[YourSearch Result]]. When the [[YourSearch Resul"+"t]] is already closed and the cursor is in the search input field the field's content is cleared so "+"you start a new query.|\n|{{{Alt-1}}}, {{{Alt-2}}},... |Pressing these keys opens the first, second e"+"tc. tiddler from the result list.|\n|{{{Alt-O}}}|Opens all found tiddlers.|\n|{{{Alt-P}}}|Toggles the "+"'Preview Text' mode.|\n|{{{Alt-'<'}}}, {{{Alt-'>'}}}|Displays the previous or next page in the [[Your"+"Search Result]].|\n|{{{Return}}}|When you have turned off the 'as you type' search mode pressing the "+"{{{Return}}} key actually starts the search (as does pressing the 'search' button).|\n\n//If some of t"+"hese shortcuts don't work for you check your browser if you have other extensions installed that alr"+"eady \"use\" these

|Description|present a 'cloud' of tags (or links) using proportional font display|
!Usage
<<<
{{{
<<cloud type action:... limit:... tag tag tag ...>>
<<cloud type action:... limit:... +TiddlerName>>
<<cloud type action:... limit:... -TiddlerName>>
<<cloud type action:... limit:... =tagvalue>>
}}}
where:
* //type// is a keyword, one of:
** ''tags'' (default) - displays a cloud of tags, based on frequency of use
** ''links'' - displays a cloud of tiddlers, based on number of links //from// each tiddler
** ''references'' - displays a cloud of tiddlers, based on number of links //to// each tiddler
* ''action:popup'' (default) - clicking a cloud item shows a popup with links to related tiddlers<br>//or//<br> ''action:goto'' - clicking a cloud item immediately opens the tiddler corresponding to that item
* ''limit:N'' (optional) - restricts the cloud display to only show the N most popular tags/links
* ''tag tag tag...'' (or ''title title title'' if ''links''/''references'' is used)<br>shows all tags/links in the document //except// for those listed as macro parameters
* ''+TiddlerName''<br>show only tags/links read from a space-separated, bracketed list stored in a separate tiddler.
* ''-TiddlerName''<br>show all tags/links //except// those read from a space-separated, bracketed list stored in a separate tiddler.
* ''=tagvalue'' (//only if type=''tags''//)<br>shows only tags that are themselves tagged with the indicated tag value (i.e., ~TagglyTagging usage)
//note: for backward-compatibility, you can also use the macro {{{<<tagCloud ...>>}}} in place of {{{<<cloud ...>>}}}//
<<<
!Examples
<<<
//all tags excluding<<tag systemConfig>>, <<tag excludeMissing>> and <<tag script>>//
{{{<<cloud systemConfig excludeMissing script>>}}}
{{groupbox{<<cloud systemConfig excludeMissing script>>}}}
//top 10 tags excluding<<tag systemConfig>>, <<tag excludeMissing>> and <<tag script>>//
{{{<<cloud limit:10 systemConfig excludeMissing script>>}}}
{{groupbox{<<cloud limit:10 systemConfig excludeMissing script>>}}}
//tags listed in// [[FavoriteTags]]
{{{<<cloud +FavoriteTags>>}}}
{{groupbox{<<cloud +FavoriteTags>>}}}
//tags NOT listed in// [[FavoriteTags]]
{{{<<cloud -FavoriteTags>>}}}
{{groupbox{<<cloud -FavoriteTags>>}}}
//links to tiddlers tagged with 'package'//
{{{<<cloud action:goto =package>>}}}
{{groupbox{<<cloud action:goto =package>>}}}
//top 20 most referenced tiddlers//
{{{<<cloud references limit:20>>}}}
{{groupbox{<<cloud references limit:20>>}}}
//top 20 tiddlers that contain the most links//
{{{<<cloud links limit:20>>}}}
{{groupbox{<<cloud links limit:20>>}}}

!Revisions
<<<
2009.07.17 [1.7.0] added {{{-TiddlerName}}} parameter to exclude tags that are listed in the indicated tiddler
2009.02.26 [1.6.0] added {{{action:...}}} parameter to apply popup vs. goto action when clicking cloud items
2009.02.05 [1.5.0] added ability to show links or back-links (references) instead of tags and renamed macro to {{{<<cloud>>}}} to reflect more generalized usage.
2008.12.16 [1.4.2] corrected group calculation to prevent 'group=0' error
2008.12.16 [1.4.1] revised tag filtering so excluded tags don't affect calculations
2008.12.15 [1.4.0] added {{{limit:...}}} parameter to restrict the number of tags displayed to the top N most popular
2008.11.15 [1.3.0] added {{{+TiddlerName}}} parameter to include only tags that are listed in the indicated tiddler
2008.09.05 [1.2.0] added '=tagname' parameter to include only tags that are themselves tagged with the specified value (i.e., ~TagglyTagging usage)
2008.07.03 [1.1.0] added 'segments' property to macro object.  Extensive code cleanup

ROE stands for //''Return On Equity''//. The ROE can be calculated as:

$\LARGE \text{ROE} =  \frac {NI}{S} \cdot \frac{S}{TA} \cdot \frac{TA}{EQ}$

Where:
$\Large TA$ = Total Assets (which is debt + equity)
$\Large EQ$ = Total Equity
$\Large S$ = Sales
$\Large NI$ = Net Income

And:
* $\LARGE \frac {NI}{S}$ => Profitability

* $\LARGE \frac{S}{TA}$ => Asset turnover

* $\LARGE \frac{TA}{EQ}$ => Leverage

In the formula for the [[WACC]]:

$\Large \text{WACC} = W_D*C_{debt} + W_E*C_{equity}$

With:
$W_D$ = [[Weight for debt]]
$C_{debt}$ = [[Cost of Debt]]
$W_E$ = [[Weigth for Equity]]
$C_{equity}$ = [[Cost of Equity]]

There are for ways to determine weight for capital:

# Book value
## $\Large \text{Market Value(Equity)} = \text{Common Shares Outstanding} * {P_0}$
# Market value:
## $\Large \text{Market Value(Debt)}$
# Marginal weights
## 
# Target weights
## Based on ideal capital structure
## Single [[WACC]] based on that so called optimal structure

* Markets have costs
* Bounded rationality
* Uncertainty and complexity
* Opportunism
* Atmosphere
Chapter 8 is an introduction to risk. Different securities bare different risks and returns. Over the last 107 years, US treasury bills provided and average return of 4% each year. The stock market returned an averag of 11.7%. These numbers give two benchmarks for the [[Opportunity Cost]]s of capital.

Risk is best judged in a portfolio context. Most investors do not put all their eggs in one basket. Risk is unpredictable. The spread of possible outcomes is measured by the [[standard deviation|Standard error]]. The standard deviation of the [[Market Portfolio]] is around 15% to 20% per year. The sensitivity to market movements is called the [[Beta]].

The variance of a portfolio can be calculated, see [[Calculating Portfolio Variance]].

A diversified portfolio investing in stocks with a beta of 2.0 will have twice the risk of  a diversified portfolio with a beta of 1.0. Diversification is a good thing for the //investor//. This does not mean that firms should diversify. Corporate diversification is redundant if investors can diversify on their own account. As diversification does not affect the firms value, [[Present Value|PV]]s add even when risk is explicitly considered. Thanks to the [[Value Additivity]] the net present value rule works even under uncertainty.

|Description|Documentation for SnapshotPlugin|
This plugin provides a macro as well as tiddler toolbar commands that creates a file or opens a new browser window containing the //rendered// HTML and CSS style definitions that are being displayed for selected elements of the current document.
!!!!!Usage:
<<<
As a macro embedded in tiddler content:
{{{
<<snapshot print label:text prompt:text id:elementID|here|viewer|story|all|ask>
}}}
where:
*''print'' //(optional)//<br>when present, causes the snapshot output to be directed to a new browser tab/window instead of saving it to a file.  In addition, the print dialog for that tab/window is automatically invoked.
*''label'' //(optional)//<br>is the text to be displayed for the command link generated by the macro
*''prompt'' //(optional)//<br>is the 'tool tip' message displayed when you mouseover the command link
*''id:...'' //(optional)//<br>specifies the document element to be captured, and can be one of:
**''elementID''<br>is a specific DOM element ID, such as "displayArea", "mainMenu", "contentWrapper", etc.
**''here''<br>the containing tiddler in which the macro (or toolbar command) occurs, including the tiddler title and subtitle (date/time/author) information.
**''viewer''<br>same as ''here'', but omits the tiddler title, subtitle and toolbar elements (i.e., it includes //only// the content of the tiddler)
**''story''<br>selects all currently displayed tiddlers (i.e., the 'story column')
**''all''<br>selects the entire document contents, including page header, main menu and sidebar displays
**''ask''<br>when the snapshot command link is clicked, a droplist is displayed so you can choose from several pre-defined elements: "current tiddler", "story column", or "entire document", or "DOM element ID..."  When DOM element ID is chosen, the droplist is refreshed to show the individual ID's for all currently rendered DOM elements (at least, the ones that have ID's).  For any given DOM element ID, only the portions of the document that are contained //within// the specified DOM element will be transcribed to the resulting snapshot or print output.  
//''NOTE: when no parameters are specified, the macro creates a snapshot file using the containing tiddler as the default element.'' (e.g., equivalent to {{{<<snapshot id:here>>}}}//

The snapshot/print functions can also be embedded as tiddler toolbar commands in [[ViewTemplate]]:
{{{
<span class='toolbar' macro='toolbar snapshotSave'></span>
<span class='toolbar' macro='toolbar snapshotPrint'></span>
}}}
* when invoked via toolbar commands, the "id:ask" option is automatically applied, and a droplist of elements to choose from is displayed.

Please note that, although the snapshot/print that is created using the HTML+CSS of the displayed content, ''there is NO javascript code'' written into the snapshot.  As a result, the snapshot only ''reproduces the //appearance// of the displayed content, allowing you to //view// or //print// the result'', but does not permit you to interact with it in other ways.

For example, even simple processing (such as mouseover highlighting) will not function from the snapshot.  You can't click a TiddlyLink to open other tiddlers, because A) there is no code that handles the click and B) there is no underlying 'storeArea' (and core code) to retrieve and render anything!  You also can't use ANY command links, since these also require javascript code (and the core) to operate. 
<<<
!!!!!Examples:
<<<
{{{<<snapshot>>}}}: <<snapshot>>
{{{<<snapshot id:mainMenu>>}}}: <<snapshot id:mainMenu>>
{{{<<snapshot print id:story>>}}}: <<snapshot print id:story>>
{{{<<snapshot print id:ask>>}}}: <<snapshot print id:ask>>
{{{<<snapshot print noCSS id:viewer>>}}}: <<snapshot print noCSS id:viewer>>
<<<
!!!!!Configuration
<<<
<<option chkSnapshotHTMLOnly>> output HTML only (omit CSS)
<<<
!!!!!Revisions
<<<
2009.10.12 1.3.0 added multi-file story snapshot
2009.09.25 1.2.1 in getSnap(), added META tag to set UTF-8 encoding for I18N support
2009.06.04 1.2.0 added handling in getSnap() so current form input values are shown in snapshots
2008.05.16 1.1.1 added try..catch around addEvent/removeEvent calls to avoid error in Opera
2008.04.28 1.1.0 removed 'viewerHTML' from 'ask' droplist and replaced with toggle for "output HTML only".  Removed 'noCSS' parameter and replaced with config.options.chkSnapshotHTMLOnly global option.  Added "select a tiddler..." to 'ask' droplist
2008.04.24 1.0.1 in saveSnap(), convert output from Unicode to UTF before passing to saveFile().  Fixes "unknown name" error in IE's file.Write() function.
2008.04.21 1.0.0 initial release - derived from [[NewDocumentPlugin]] with many improvements, including: "ask for ID" using droplist of available DOM elements, use "<base href=...>" for correctly resolving image references, wrap 'viewer only' output in class="tiddler viewer" for proper application of inherited CSS styles, snapshotSave and snapshotPrint tiddler toolbar command definitions, and more...

__Excerpted revisions from [[NewDocumentPlugin]] (obsolete)__
2008.04.20 1.8.0 added support for 'noCSS' and 'viewer' params for alternative snapshot output
2007.03.30 1.7.0 added support for "print" param as alternative for "snap".  When "print" is used, the filename is ignored and ouput is directed to another browser tab/window, where the print dialog is then automatically triggered.
2007.03.30 1.6.1 added support for "here" keyword for current tiddler elementID and "prompt:text" param for specifying tooltip text
2006.10.18 1.5.0 new optional param for 'snap'... specify alternative DOM element ID (default is still "contentWrapper").  Based on a suggestion from Xavier Verges.
2006.03.09 1.2.0 added special "snap" filter parameter to generate and write "snapshot" files containing static HTML+CSS for currently rendered document.
2006.02.03 1.0.0 Created.

The [[NPV]] can also be expressed as a quotient rather than a difference. Define
$\large \text{Net Present Value (NPV)}_q = \frac{\text{PV (expected cash flows)}}{\text{PV(capital expenditures)}}$
or
$\large \text{NPV}_q$ = $\Large \frac{S}{PV(X)}$

Using this way of expressing the NPV the rule becomes if $\large \text{NPV}_q$ >1 then invest, if $\large \text{NPV}_q$ < 1 then don't invest.

$\large \text{NPV}_q$ is used to determine if a call option should be exercised //''at expiration''//. By adding this condition $\large \text{NPV}_q$ combines four of five determinants of option value (see [[Options]]), The stock price $S$, the expenditure costs $X$, the [[Risk free rate of return]] (part of the denominator to discount the costs) and t.

Activity Based Costing (ABC) is an alternative to the traditional way of accounting Traditionally it is assumed that high volume customers are profitable customers. A loyal customer is also a profitable customer. And profits will follow a happy customer. Studies about customer profitability have unveiled that the above ideas are not necessarily true. ABC is a costing model that identifies the cost pools, or activity centers, in an organization. It assigns costs to products and services (cost drivers),based on the number of events or transactions that are taking place in the process of providing a product or service. As a result, Activity Based Management can support managers to see how shareholder value can be maximized and how corporate performance can be improved.

</html>

Typical benefits of Activity-Based Costing:
* Identify the most profitable customers, products and channels.
* Identify the least profitable customers, products and channels.
* Determine the true contributors to- and detractors from- financial performance.
* Accurately predict costs, profits and resources requirements associated with changes in production volumes, organizational structure and costs of resources.
* Easily identify the root causes of poor financial performance.
* Track costs of activities and work processes.
* Equip managers with cost intelligence to stimulate improvements
* Facilitate a better [[Marketing Mix]]
* Enhance the bargaining power with the customer.
* Achieve better Positioning of products
In [[Principles of Corporate Finance]] an two types of [[Asset]]'s are described:
* [[Real assets]] that ''need to be paid for''
** Tangible such as machinery, factories and offices
** Non-tangible assets such as technical expertise, trademarks and patents.
* [[Financial assets]] or securities
** A company sells claims on their 'real assets' in order to acquire money.
The role of a [[Financial Manager]] is to answer two questions:
1) Which [[Real assets]] should the firm invest in?
2 How should the cash for the investment be raised?
In large business separation of ownership and management should be separated, purely because they have many owners and managing it together would be impossible. Separating the roles introduces the [[agency dilemma|Agency theory]]. [[Agency costs]] are incurred when
1) Managers do not attempt to maximize the firms value
2) Shareholders spend extra money to monitor and control managers
For an option to have significant economic value, there has to be:

* A restriction exists on competition in the event of the contingency.
** In a perfectly competitive product market, no contingency, no matter how positive, will generate positive net present value.
* Real options are most valuable when you have exclusivity.
* Real options become less valuable as the barriers to competition become less steep.
In [[Principles of Corporate Finance]] the concept of //net present value// or //NPV// is defined as a project's net contribution to wealth ([[Present Value]]) minus initial investments. [[NPV]] is a measure of the difference between how much an asset is worth and what it costs. When it is worth more than it costs, the project has a positive NPV and the cooperation goes ahead and invests.  A very simple to understand interpretation of the NPV is that it is your net profit at the end of the investment period corrected for inflation.

Put in another way; the NPV = PV(expected benefit cash flows) //minus// PV (capital expenditure). The decision is to invest if the NPV > 0. 

Net present value is calculated as present value plus any immediate cash flow:

$\Large \text{Net Present Value (NPV)} = C_0 + \frac{C_1}{1+r}$

If $\large C_0$ is negative the immediate cash flow is an investment or [[Cash Outflow]]. For example, if a dentist wishes to purchase a new dental practice, he may calculate the net present value over a number of years to see if he will recover his investment in a reasonable period of time. If the ask price for the dental practice is \$500,000, this is the present cash outflow used in the calculation. If the discounted cash inflow over, say, two years, is greater than or equal to \$500,000, then the investment will likely be profitable. For multiple varying discount factors and multiple years the formula becomes:

$\Large NPV = C_0 + \sum{\frac{C_t}{(1+r_t)^t}}$

There are three points to make about NPV:
1) A dollar today is worth more than a dollar tomorrow
2) The NPV depends on the forecasted cash flows from a project and takes the [[Opportunity Cost]]s into account
3) Because the present values are translated to 'dollars today' NPV's can be added up:

$\Large NPV (A+B) = NPV(A) + NPV(B)$

/***
|''Name''|ImageMacroPlugin|
|''Version''|0.9.4|
|''Description''|Allows the rendering of svg images in a TiddlyWiki|
|''Author''|Osmosoft|
|''License''|[[BSD|http://www.opensource.org/licenses/bsd-license.php]]|
|''Notes''|Currently only works in modern browsers (not IE)|
|''Requires''|BinaryTiddlersPlugin|
!Usage
{{{<<image SVG>>}}} will render the text of the tiddler with title SVG as an SVG image (but not in ie where it will fail silently)
!!Parameters
width/height: specify width/height parameters
link: make the image link to a given location
tiddlyLink: link to a tiddler

!Notes
Binary tiddlers in TiddlyWeb when passed through the wikifier will be shown as images.
eg. {{{<<view text wikified>>}}} on a binary tiddler will show the image.
{{{<<view fieldname image>>}}}
will render the value of the tiddler field 'fieldname' as an image. This field can contain a tid
{{{<<image SiteIcon>>}}}
will create an image tag where the tiddler has content type beginning image and not ending +xml
will attempt to create svg object in other scenarios
{{{<<image /photos/x.jpg>>}}}
will create an image tag with src /photos/x.jpg as long as there is not a tiddler called /photos/x.jpg in 
which case it will render that tiddler as an image. Note for the case of svg files it will attempt to render as an svg if possible via the image
tag. It doesn't embed the svg in the dom for security reasons as svg code can contain javascript.

Welcome to your brand new [[TiddlySpace]]@glossary.

To get started with this blank [[TiddlySpace]]@glossary, you'll need to modify the following [[tiddlers|Tiddler]]@glossary:
* If you don't like the color scheme click <<RandomColorPaletteButton>> to generate a new random acolor scheme.
* Upload a [[SiteIcon|SiteIcon tiddler]]@glossary. [[Your SiteIcon|SiteIcon]] gives your space an identity to make it recognisable to others. A good site icon will be square and at least 48*48 pixels size.
<<binaryUploadPublic title:SiteIcon>>
* [[SiteTitle]] & [[SiteSubtitle]]: The title and subtitle of the site, as shown above (after saving, they will also appear in the browser title bar)
* [[MainMenu]]: The menu (usually on the left)
* [[DefaultTiddlers]]: Contains the names of the tiddlers that you want to appear when the ~TiddlySpace is opened
* Many features of ~TiddlySpace are accessed via the backstage bar located at the top of the page. You can toggle it on or off using the button in the top right corner of the screen.

!Usage
Draw a graph
{{{
<<graph dimX dimY nolinks backlinks strict tags:tags anim:timing filter:tags start:tiddlers plot:tiddler>>
}}}
Options
* ''nolinks''  : do not follow forward links and tags
* ''nogroups'' : do not treat "tag" links as group links
* ''backlinks'' : follow reverse links
* ''strict'' : exclude all node not tagged with "tags" (otherwise direct links are included)
* ''notags'' : ignore tag links
* ''fields'' : read from fields instead of slices
* ''anim'':animate graph for some time
* ''tags'' : choose tiddlers with specified tags
* ''filter'' : exclude those tiddler with specified tags
* ''start'' : check also from these tiddler (+ thier direct links)
* ''plot'' : use the text of this tiddler to draw a graph from the text and not the tiddlers node, annot, link, type in an array. '->' for direct link, '<-' for backlinks and ':>' or ':<' for tag/group link.
Change node properties with slices
* ''color'' : graph.fillStyle, graph.strokeStyle, 
* ''position'' : graph.X, graph.Y, graph.repulse
* ''display'': graph.title, graph.subTitle, graph.ignore
* ''life'' : graph.endLife, graph.startLife
In GraphConfig, you can configure style for links by combining
* ''link type'': direct, titled, bracket, back, tag
* ''display'' : fillStyle, strokeStyle, lineWidth, margin, rounded
!!History
|15.01.09| 0.1.0|Initial release, draw graph with anotated nodes from tiddler|
|16.01.09| 0.2.0|Add animation (the 3 parameter is the number of steps calculated)|
|19.01.09| 0.3.0|Added ability to move nodes, graph dynamically updated|
|22.01.09| 0.4.0|Support of multiple tags and filter also|
|22.01.09| 0.5.0|Can set color for node and links, depending of it's type|
|23.01.09| 0.6.0|Annotated links can be overiden by a tiddler|
|23.01.09| 0.6.1|Fix a bug : now start can have multiple tiddlers|
|23.01.09| 0.7.0|Now a new slice graph.subtitle|
|28.01.09| 0.8.0|Add preliminary time support in graph : graph.endLife|
|02.02.09| 0.8.1|Add "strict" filter for some graph displaying unwanted nodes|
|03.02.09| 0.8.2|Add graph.ignore to filter some individual links in graph|
|04.02.09| 0.8.3|Initial position of node is not 0 any more, so that no more random graphs|
|04.02.09| 0.9.0|Option to read from slices or from fields|
|05.02.09| 0.9.1|Add : graph.startLife|
|05.02.09| 0.9.2|Add : graph.repulse : so that nodes can be more isolated (useful for anotated links|
|13.02.09| 0.9.3|Links can be individually colored in their tiddler if it exist, rather than in GraphConfig|
|20.02.09| 0.10.0|Add : rounded rectangle + collapsible text for links|
|13.04.09| 0.11.0|Add direct graph plotting from table syntax|
|13.04.09| 0.12.0|Add group node support (eq tag link = group link)|
|13.04.09| 0.12.0|Add 'dot' syntax to direct graph (it means that it can read plain text to draw graphs|
!Known BUGS
* In some cases when every node in the graph have exactly the same tags, it can create a NaN anomaly. To bypass it, just change some tags.
* the new functionnalité collapsible links is not yet compatible with "full links" ... full links are links described in a tiddler

''Using JavaScript''

To give you a lot of flexibility the [[ForEachTiddlerMacro]] uses JavaScript in its arguments. Even if you are not that familiar with JavaScript you may find forEachTiddler useful. Just have a look at the various ready-to-use [[ForEachTiddlerExamples]] and adapt them to your needs.

''The Elements of the Macro''

The arguments of the ForEachTiddlerMacro consist of multiple parts, each of them being optional.

<<slider chkFETInClause [[inClause]] "inClause" "inClause">>
<<slider chkFETWhereClause [[whereClause]] "whereClause" "whereClause">>
<<slider chkFETSortClause [[sortClause]] "sortClause" "sortClause">>
<<slider chkFETScriptClause [[scriptClause]] "scriptClause" "scriptClause">>
<<slider chkFETActions [[Action Specification]] "Action Specification" "Action Specification">>

''Using Macros and ">" inside the forEachTiddler Macro''

You may use other macro calls into the expression, especially in the actionParameters. To avoid that the {{{>>}}} of such a macro call is misinterpreted as the end of the {{{<<forEachTiddler...>>}}} macro you must escape the {{{>>}}} of the inner macro with {{{$))}}} E.g. if you want to use {{{<<tiddler ...>>}}} inside the {{{forEachTiddler}}} macro you have to write {{{<<tiddler ...$))}}}.

In addition it is necessary to escape single {{{>}}} with the text {{{$)}}}.

''Using {{{<<tiddler ... with: ...>>}}} to re-use ForEachTiddler definitions''

Sometimes you may want to use a certain ForEachTiddler definition in slight variations. E.g. you may want to list either the tiddlers tagged with "ToDo" and in the other case with "Done". To do so you may use "Tiddler parameters". Here an example:

Replace the variable part of the ForEachTiddler definition with $1 ($2,... $9 are supported). E.g. you may create the tiddler "ListTaggedTiddlers" like this
{{{
<<forEachTiddler 
 where 
 'tiddler.tags.contains("$1")'
>>
}}}

Now you can use the ListTaggedTiddlers for various specific tags, using the {{{<<tiddler ...>>}}} macro:
{{{
<<tiddler ListTaggedTiddlers with: "systemConfig">>
}}}
{{{
<<tiddler ListTaggedTiddlers with: "Plugin">>
}}}

What Does Short (or Short Position) Mean?
1. The sale of a borrowed security, commodity or currency with the expectation that the asset will fall in value.

2. In the context of options, it is the sale (also known as "writing") of an options contract.

Opposite of [[Long]] (or long position)". 
In [[Entrepreneurial Finance]]  the Certainty Equivalent Cash Flow or CEQ is defined as a common method of estimating [[Present Value]]. The second common method mentioned is the [[Risk Adjusted Discount Rate]]. In the CEQ method instead of adjusting the discount rate (which is done in the [[RADR]]) the risk adjustment is made directly to the cash flow. After that the risk-adjusted or, better in this case the ''certainty equivalent'' cash flow is converted to [[Present Value]] by discounting at the risk free rate. Thus, if:

$\Large C_{jt}$ is the expected future cash flow of asset $\Large j$ at time $\Large t$ the certainty equivalent cash flow $\Large CE(C_{jt})$ can be described as follows:

$\Large CE(C_{jt})$ $\Large =$ $\Large C_{jt} - RD_{jt}$

Where:
$\Large RD_{jt}$ is the dollar valued discount to $\Large C_{jt}$ that is required to convert the risky expected cash flow to its certainty equivalent.

Certainty Equivalent Cash Flow (CEQ) is:

$\Large PV$ - $\LARGE \sum{\frac{C_t-RD_r}{(1+r_{pt})^t}}$

Issues:
* What cash flows should be valued?
* How risky cash flows adjusted to their certainty equivalents?
* What is the discount rate for valuing certain future cash flows?

Dogs or more charitably called pets, are units with low market share in a mature, slow-growing industry. These units typically "break even", generating barely enough cash to maintain the business's market share. Though owning a break-even unit provides the social benefit of providing jobs and possible synergies that assist other business units, from an accounting point of view such a unit is worthless, not generating cash for the company. They depress a profitable company's return on assets ratio, used by many investors to judge how well a company is being managed. Dogs, it is thought, should be sold off.

Part of: [[BCG Matrix]]
A Financial Cash Flow is not necessarily directly intertwined with the transformation process in the [[Cash conversion cycle]]
In [[Principles of Corporate Finance]] //Discounted Cash Flow// is defined as future [[Cash Flow]]s multiplied by [[Discount Factor]]s to obtain [[Present Value]] ]. Cash flows are discounted for two reasons:

1) A dollar today is worth more than a dollar tomorrow
2) A safe dollar is worth more than a risky one.

A valuation method used to estimate the attractiveness of an investment opportunity. Discounted cash flow (DCF) analysis uses future free cash flow projections and discounts them (most often using the weighted average cost of capital) to arrive at a present value, which is used to evaluate the potential for investment. If the value arrived at through DCF analysis is higher than the current cost of the investment, the opportunity may be a good one.

There are a lot of interesting people using ~TiddlySpace that you might like to keep track of and interact with. There are a number of ways of doing this.

If you see a number in the speech bubble in one of your tiddlers, it means that someone is writing about the same thing as you. You can find out what they're saying by clicking on it. Likewise, if you see something interesting in someone else's space, you can respond to it and write up your own thoughts on the subject by clicking "Reply to this tiddler".

Additionally, if you find anyone interesting, or you find an interesting looking space and you'd like to know when it's changed, you can "follow" that space. To do this, simply create a tiddler with the title: {{{@space-name}}} and tag it {{{follow}}}. If you want, you can store some notes about that space in the body of the tiddler.

If you then want to know what happening, simply [[include|How do I include/exclude spaces?]]@docs the @tivity space and then visit your activity stream at [[/activity|/activity]], or just visit the @tapas space directly.

!Not sure who to follow?
Here's a few suggestions:

|''Name''|TiddlySpaceFollowingPlugin|
|''Version''|0.6.9|
|''Description''|Provides a following macro|
|''Author''|Jon Robson|
|''Requires''|TiddlySpaceConfig TiddlySpaceTiddlerIconsPlugin ErrorHandler|
|''License''|[[BSD|http://www.opensource.org/licenses/bsd-license.php]]|
!Usage
Tag a tiddler with "follow" to express a list of followers.
Using the {{{<<followTiddlers X>>}}}
will reveal the number of tiddlers with name X in the set of spaces the *current* user viewing your space follows.
{{{<<following jon>>}}} will list all the users following Jon.
{{{<<followers jon>>}}} will list all the followers of jon.
{{{<linkedTiddlers>>}}} will list all tiddlers across TiddlySpace linked to the current tiddler
{{{<linkedTiddlers follow:yes>>}}} will list all tiddlers across TiddlySpace that come from your list of followers
adds spaceLink view type {{{<<view server.bag spaceLink>>}}} creates a link to the space described in server.bag
{{{<<view server.bag spaceLink title>>}}} makes a link to the tiddler with title expressed in the field title in space server.bag
If no name is given eg. {{{<<following>>}}} or {{{<<follow>>}}} it will default the current user.

A put option gives the buyer of the option the right to sell the underlying asset at a fixed price at any time prior to the expiration date
of the option. The buyer pays a price for this right.

At expiration,
* If the value of the underlying asset (S) < Strike Price(K)
** -> Buyer makes the difference: K-S
* If the value of the underlying asset (S) > Strike Price (K)
** -> Buyer does not exercise

More generally,
* The value of a put decreases as the value of the underlying asset increases
* The value of a put increases as the value of the underlying asset decreases

A [[Pay-off Diagram]] for a ''buyer'' of put option looks like this: you start out with a loss and gain profit if the actual share price becomes lower than the strikeprice. Buying a put option buys you protection against lower stock prices.

The 20-225% rule states that typically 20% of the customers account for 225% of the profits (or value added)
!URL
http://www.virtual.co.nz/index.php/StrategicSnippets/WouldThe20-225RuleMakeYouMoreEffective

!Description
Recent research has shown that once the full cost of supporting customers is taken into account, the majority of customers (usually around 80%) are not profitable at all. In fact studies carried out by Professors Cooper and Kaplan at the Harvard Business School have led them to the so called “20 - 225 rule". It applies equally to both private sector and public sector organisations.

The Rule states that typically 20% of the customers account for 225% of the profits (or value added), which of course means that the other 80% “lose” 125 percent of the profits (or value added).

It also says that typically 20% of the products (or services) account for 225% of the profits (or value added), which of course means that the other 80% “lose” 125 percent of the profits (or value added).

This is dangerous, not only because we end up supporting many customers and products which lose us money, but equally dangerously, we don't support as well as we should, the 20% that REALLY matter.

In probability theory and statistics, covariance is a measure of how much two variables change together.

$\Large {Cov}(X,Y) = {E}\big[X Y\big]  - {E}[X] \cdot {E}[Y]$

Where where ${E[}X]$ is the [[Expected Value]] of X.

We use _ to get the 'bottom' parts of summations, products, and limits, as well as the subscripts of logarithms. We use ^ to get the 'top' parts of sums and products. (Integration symbols work the same way, as you'll see in the calculus section.) Click here for a few other commands which take 'bottom' parts.

|Symbol|Command|h
|$\large \textstyle \sum_{i=1}^{\infty}\frac{1}{i}$|\\sum_{i=1}^{\\infty}\frac{1}{i}|
|$\large \textstyle \prod_{n=1}^5\frac{n}{n-1}$|\\prod_{n=1}^5\\frac{n}{n-1}|
|$\large \textstyle \lim_{x\to\infty}\frac{1}{x}$|\\lim_{x\to\infty}\\frac{1}{x}|
|$\large \textstyle \log_n n^2$|\\log_n n^2|

Some of these are prettier in display mode:
|Symbol|Command|h
|$\large \displaystyle \sum_{i=1}^{\infty}\frac{1}{i}$|\\displaystyle \\sum_{i=1}^{\\infty}\\frac{1}{i}|
|$\large \displaystyle \prod_{n=1}^5\frac{n}{n-1}$|\\displaystyle \\prod_{n=1}^5\\frac{n}{n-1}|
|$\large \displaystyle \lim_{x\to\infty}\frac{1}{x}$|\\displaystyle \\lim_{x\\to\\infty}\\frac{1}{x}|

Note that we can use sums, products, and logarithms without _ or ^ modifiers.
|Symbol|Command|h
|$\large \displaystyle \sum\frac{1}{i}$|\displaystyle\sum\frac{1}{i}|
|$\large \displaystyle \frac{n}{n-1}$|\displaystyle\frac{n}{n-1}|
|$\large \displaystyle \textstyle \log n^2$|\log n^2|

<<tiddler [[Certainty Equivalent Cash Flow]]>>
The length of time required to recover the cost of an investment. Calculated as

''Pay back period'' = $\LARGE \frac{Cost of Project}{Annual Cash Inflows}$

Using the following example:
|Project|\[C_0\]|\[C_1\]|\[C_2\]|\[C_3\]|Payback|NPV at 10%|h
|A|-2000|500|500|5000|3|+2624|
|B|-2000|500|1800|0|2|-58|
|C|-2000|1800|500|0|2|+50|

# The payback rule ignores all cash flows after the cut off date.
# The payback rule gives equal weight to all cash flows before the cutoff date.

In [[Principles of Corporate Finance]] a financial manager's role is to answer two questions:
1) Which [[Real assets]] should the firm invest in?
2 How should the cash for the investment be raised?

<<image /static/files/MBI/Module%2012/financialmanager.PNG width:600>>

# The flow starts when the firm sells securities to investors to raise cash
# The cash is used to purchase real assets
# If the firm does well, the return on these assets generate cash flows that more than repay the initial investment
#
## This cash can be reinvested in the firm
## Or return to the investors who bought the securities

Three types of financial managers exists:
# The ''Treasurer'', responsible for cash management, raising capital and banking relationships, common in small firms
# The ''Controller'', responsible for preparation of financial statements, accounting and taxes, next step for larger firms
# The ''CFO'', responsible for financial policy and corporate planning, required for still larger firms

Assets in place are cash producing assets that can be evaluated with [[DCF]] methodologies.
In accountancy, Days Sales Outstanding (also called Days Receivables) is a calculation used by a company to estimate their average collection period. A low number of days indicates that the company collects its outstanding receivables quickly. The Days Sales Outstanding (DSO) figure is an index of the relationship between outstanding receivables and credit account sales achieved over a given period. The DSO analysis provides general information about the number of days on average that customers take to pay invoices.

DSO is considered an important tool in measuring liquidity. DSO tends to increase as a company becomes less risk averse. Higher DSO can also be an indication of poor follow up on delinquencies, or higher DSO might be the result of inadequate analysis of applicants for open account credit terms. An increase in DSO can result in cash flow problems, and may result in a decision to increase the creditor company's bad debt reserve.

Days Sales Outstanding, or DSO, is calculated as: Total Outstanding Receivables at the end of the period analyzed divided by Total Credit Sales for the period analyzed (typically 90 or 365 days), times the number of days in the period analyzed. That is,

{{{
DSO = (Receivables/Sales) * Days in Period (can use average receivables as a more conservative estimate)
}}}

There are 8 types of cash flow:
# Cash inflow from sales [[Operational Cash Flow]]
# Cash outflow to customers [[Operational Cash Flow]]
# Interest received [[Financial Cash Flow]]
# Dividend payed [[Financial Cash Flow]]
# Receiving a loan [[Financial Cash Flow]]
# Paying back a loan [[Financial Cash Flow]]
# Profit Taxes [[Financial Cash Flow]]
# Subsidies [[Financial Cash Flow]]

An //Annuity// is financial product sold by financial institutions that is designed to accept and grow funds from an individual and then, upon annuitization, pay out a stream of payments to the individual at a later point in time. The [[Present Value]] of an annuity is:

$\large \text{PV (Annuity)}$ $=$ $\LARGE \frac{1}{r} - \frac{1}{r(1+r)^t}$

In  [[Principles of Corporate Finance]] an annuity is defined as a an investment that produces a level stream of cash flows for a defined number of periods.

The future value of an annuity of a level of cash streams of \$1 is:

$\large \text{PV (Future Annuity)}$ $=$ $\LARGE \frac{(1+r)^t-1}{r}$

After estimating the profitability of each customer, it is informative to rank them from most to least profitable and plot the accumulated profit in a graph — the x-axis has the ordered list of customers; the y-axis has the accumulated profit. Therefore, the accumulated profit for the most profitable customer is its profit, for the two most profitable customers is the addition of their profits, and so on. This graph gives a good picture of how profitability happens in a company.

This graph frequently proves that companies have very heterogeneous client portfolios. Often, the distribution of revenues and profits fits the 80/20 rule, whereby the company makes 80% of its revenues or profit from 20% of its customers. Typically it also reveals that a profitable company is making money with one group of customers and losing money with another large group of customers. Even stronger stated is the [[20-225% rule]].

The shape of the graph resulting from this type of analysis often resembles the top of a whale coming out of the water so the pattern is called the whale curve.

Growing [[Perpetuities|Perpetuity]] are perpetuities where the cash you need to provide grows at a constant rate. This can be calculated by:

''Present Value of Growing Perpetuity'' = $\LARGE \frac{C_1}{r-g}$

Where $r$ is the [[Discount Factor]] and $g$ the growth rate in cost.
* Simultaneity: The discount rate depends on the standard deviation (risk) of the project. But value of the project depends on the discount rate again.
* Solution: Certainty equivalent version ([[Certainty Equivalent Cash Flow]]) of CAPM
* CAPM may not be the right model to value expected returns (ongoing academic debate)
* CAPM is not inconsistent with real options valuations as the CAPM can be used to value the underlying 
* Required rate of return for a new venture:

$\LARGE r_{proj}$ = $\LARGE R_F + \beta_{proj}(r_M - r_F) + \text{Effort} + \text{Illiquidity}$
A t-period Growing [[Annuities|Annuity]] is calculates by the following formula:

''t-period growing annuity'' = $\LARGE \frac{1}{r-g} -\frac{1}{r-g} * \frac{(1+g)^t}{(1+r)^t}$

In finance two different interpretations for options exist:
* [[Financial Options]] as found in the financial markets
* [[Real Options]] which are an attempt to apply similar concepts to entrepreneurial project and financial decisions.

When mapping project characteristics onto call option variables you can see the following similarities:
|Project|Variable|Option|h
|Expenditures required to acquire the asset|''$X$''|Exercise price|
|Value of the operating assets to be acquired|$S$|Stock price|
|Length of the time decision may be defered|$t$|Time to experation|
|Riskiness of the underlying operating assets|$\sigma ^2$|Variance of returns on stock|
|[[Time value of money]]|$r$|[[Risk free rate of return]]|

When a decision cannot be delayed standard [[DCF]] techniques as [[NPV]] or NPV_q are sufficient to model the decision. However if the decision //''can''// be delayed, the project is more like an option and also will need to take the riskiness of the project into account.

A very simple summary of using real options as an approach for investment decisions is:
* Use [[DCF]], [[NPV]] or [[IRR]] in most cases.
* Only for projects for which have very good data and estimates of how risk accummulates over time a real option approach may be applicable.

The riskiness is represented by the remaining option variable $\large \sigma$. The variability, per unit time, of the project is represented by the variance of the returns, $\large \sigma ^2$. Cumulative variance is a measure of how things could change over time and represented as $\large \sigma ^2 t$

<<image /static/files/MBI/Module%2013/npvqgraph.png width:700>>
The equity or investor IRRs are calculated on the relevant cash flow to investors, with payments from investors (pure equity paid in, drawings on sub debt etc) as initial negatives, and payments to investors (dividends, payments to sub debt etc. as appropriate) as positives.

See also: [[IRR]]
When is there a real option embedded in a decision or an asset? The following conditions apply:

* There has to be a ''clearly defined underlying asset'' whose ''value changes over time'' in unpredictable ways.
* The payoffs on this asset (real option) have to be contingent on an ''specified event occurring within a finite period''

Question marks (also known as problem child) are growing rapidly and thus consume large amounts of cash, but because they have low market shares they do not generate much cash. The result is a large net cash consumption. A question mark has the potential to gain market share and become a star, and eventually a cash cow when the market growth slows. If the question mark does not succeed in becoming the market leader, then after perhaps years of cash consumption it will degenerate into a dog when the market growth declines. Question marks must be analyzed carefully in order to determine whether they are worth the investment required to grow market share.

An American option can be exercised at any time prior to its expiration, while a European option can be exercised only at expiration.
* The possibility of early exercise makes American options more valuable than otherwise similar European options.
* However, in most cases, the time premium associated with the remaining life of an option makes early exercise sub-optimal.
* While early exercise is generally not optimal, there are two exceptions:
** One is where the underlying asset pays large dividends, thus reducing the value of the asset, and of call options on it. In these cases, call options may be exercised just before an ex-dividend date, if the time premium on the options is less than the expected decline in asset value.
* The other is when an investor holds both the underlying asset and deep in the money puts on that asset, at a time when interest rates are high. 

The time premium on the put may be less than the potential gain from exercising the put early and earning interest on the exercise price.
In [[Principles of Corporate Finance]] a replicating portfolio is defined as the combination of:
* Borrowing money
* Buying a ratio of stock
Such that you replicate exactly the payoff from one call option. The number of shares need to replicate one call is called the ''option delta'' or ''hedge ratio''.

Take the example of a stock with has a current stock price of \$80,- with a maximum downside potential of 25% drop and an upside of 33% increase. This means that the stock can move between 
* \$60,-
* \$106,67,-

A call option for \$80,- in this case would be moving between:
* \$0,- (in the case there the stock price was below \$80,-)
* Between \$0,- and \$26,67 if the stock price was moving between and  \$106,67,-
* \$26,67 (in the case the stock price was exactly \$106,67,-)

How should we value such a call option? There are two methods of calculation:

!Calculate option delta
The option delta can be calculate as follows:

$\Large \text{Option delta}$ = $\Large \frac{\text{Spread of option prices}}{\text{Spread of share prices}}$=$\LARGE \frac{26.67 - 0}{106.67 - 60}$=$\LARGE \frac{26.67}{46.67}$=$\LARGE \frac{4}{7}$

$\LARGE \frac{80 - ((4/7) \cdot 80)}{1.025}$= $\Large 33.45$

A more intuitive way of calculating the amount of money that needs to be borrowed is to simply subtract 

The value of the call is then:

$\Large \text{Value of call}$ = $\Large \text{Value of (4/7) shares}$ -  $\Large \text{33.45 bank loan}$ =
 = $\Large 80 \cdot (4/7) - 33.45$  =  $\Large 12.26$

The Dividend Growth Model (Gordon-Shapiro):

$\Large	\displaystyle {Present\ Value} =  \sum_{t=1}^{\infty}\frac{D_t}{(1+C_{equity})^t}$

The $\Large C_{equity} = \frac{D_1}{P_0}+g$

Where
* $\Large P_0$ is the present value

A perpetuity is a constant stream of identical cash flows with no end.  The formula for determining the [[Present Value]] of a perpetuity is as follows:

$\Large PV$ $=$ $\LARGE \frac{C_1}{(1+r)^1} +  \frac{C_2}{(1+r)^2} +  \frac{C_3}{(1+r)^3} + ... = \frac {C}{r}$

In [[Principles of Corporate Finance]] the perpetuity is defined as an [[Annuity]] in which the periodic payments begin on a fixed date and continue indefinitely.

This is an early release of the DiffFormatterPlugin, which extends the TiddlyWiki syntax to support Diff
text formatting.

The Diff formatter is different from the other formatters in that Tiddlers are not required to be
tagged: instead the Diff format adds formatting that augments TiddlyWiki's format.

The Diff formatter adds the following:
# ^+ for added
# ^- for removed
# ^"""@@ """, """--- """ and """+++ """ for special markers

Please report any defects you find at http://groups.google.co.uk/group/TiddlyWikiDev

In [[Principles of Corporate Finance]] the risk neutral valuation is calculated by assuming that investors are indifferent to risk and expect return on stock to be equal to the risk-free rate of interest. Furthermore it assumed that stock have a certain downside potential $\Large d$ and and and upside potential $\Large u$. There is a certain chance $\Large p$ that the stock will go up with percentage $\Large u$ and a chance of $\Large 1-p$ that the stock will go down with percentage $\Large d$. This gives:

$\Large \text {Expected Return}$ = $\Large p \cdot u + (1-p) \cdot d = r$

This gives the general probability of rise of the stock:

$\Large p$ = $\LARGE \frac{(1 + r) -d}{u - d}$

Valuing a call this way gives ($\Large k$ is the exercise price):

$\Large \text{Expected value of a call}$ = $\LARGE \frac{p \cdot max(Su-k,0) + (1 - p) \cdot max(Sd-k,0)}{1 + r}$

Using the same example as in [[Replicating Portfolio]] we get:

$\Large p$ = $\LARGE \frac{(0.025) - (-0.25)}{0.33 - (- 0.25)}$ = $\Large .471$

$\Large \text{Expected value of a call}$ = $\LARGE \frac{0.471 \cdot max(106.67 - 80,0) + (1 - 0.471) \cdot max(60-80,0)}{1 + r}$ = $\Large 12.26$
In [[Principles of Corporate Finance]] a //Discount Factor// is defined to be the [[Present Value]]  of 1\$ at a defined future date.
In finance, the ''//Cost of Equity//'' is the minimum rate of return a firm must offer shareholders to compensate for waiting for their returns, and for bearing some risk.

The cost of equity capital for a particular company is the rate of return on investment that is required by the company's ordinary shareholders. The return consists both ofdividend and capital gains, e.g. increases in the share price. The returns are expected future returns, not historical returns, and so the returns on equity can be expressed as the anticipated dividends on the shares every year in perpetuity. The cost of equity is then the cost of capital which will equate the current market price of the share with the discounted value of all future dividends in [[Perpetuity]]

The cost of equity reflects the [[Opportunity Cost]] of investment for individual shareholders. It will vary from company to company because of the differences in the business risk and financial or gearing risk of different companies.

$\Large \text{Cost of Equity} = \frac{\text{Next Year's Dividends and Equity Appreciation per Share}}{\text{Current Market Value of Stock}}\ +\text{Growth Rate of Dividends}$

There are also a variety of other ways to estimate the cost of equity. For example, using the [[CAPM Model]], the cost of equity is the product of the Market Risk Premium and the equity's beta plus the risk-free interest rate:

$\Large \text{Cost of Equity} = \text{Market Risk Premium} * \text{Equity Beta + Riskless Rate}$

Cost of equity = Risk free rate of return + Premium expected for risk
Cost of equity = Risk free rate of return + Beta x (market rate of return- risk free rate of return) Where Beta= sensitivity to movements in the relevant market: $\Large E_s = R_f + \beta_s(R_m - R_f)$

Where:

$\Large E_s$
    The expected return for a security
$\Large R_f$
    The expected risk-free return in that market (government bond yield)
$\Large β_s$
    The sensitivity to market risk for the security
$\Large R_m$
    The historical return of the stock market/ equity market
$\Large (R_m-R_f)$
    The risk premium of market assets over risk free assets.

The risk free rate is taken from the lowest yielding bonds in the particular market, such as government bonds.

Download the article [[here|/static/files/MBI/Module%2013/Captial%20projects%20as%20real%20options%20-%20hbr.pdf]]

The article describes an approach to use option value theory to help with in company project investment decisions. There are several examples where using real option analysis give a better view of your project:
# An R&D program may both:
## generate a cash producing new product , as well as
## ''//opportunities for further R&D aimed to create yet more new products//''
# Investing in a new market may:
## Lead to immediate cash flow, as well as,
##  ''//Future expansion possibilities//''
# Replacing:
## a first-generation technology with a second, makes it possible to eventually,
##  ''//replace the second with a third//''

All of the above examples, contain //[[Assets in place]]// (first bullet item) and //growth options// (second bullet item). The value of the growth options are discarded in traditional [[DCF]] analysis.

The article goes on to describe the concept of [[NPV_q]], [[Options]] and [[Real Options]]. The final 'punch line' of the article is the following diagram:

<<image /static/files/MBI/Module%2013/mappingprojectstocalloptions.png width:700>>

Note to myself: ''Quadrant 3 lists //NPV < 0// which was counter intuitive at first''. The reason this can happen is that if the risk free rate of return is > 0. The location of this curve varies with r and σ. The curve is located by holding r and σ constant as t varies, and solving for the [[NPV_q]] that corresponds to [[NPV]]=0. Note that in the extreme case of r=0, the curve is a vertical line passing through  [[NPV_q]] =1. As r increases, the slope of the curve decreases, bending to the right, as shown in Figure 6.

<<image /static/files/MBI/Module%2013/npvqgraph.png width:700>>

In the graph above there are three sitiuations:
# At the top there are options with no cumulative variance, either time has run out or there is no variance. These options are ''in the money'' and should be exercised immediately. There is no value in waiting.
# Just below are options that are in the money but for which there is still some cumulative variance. The company should wait, //if possible//, to exercise these options. Early exercise may be desirable when the underlying asset is 'wasting' (subject to competitors actions)
# Finally at the bottom there are options that are promissing because [[NPV_q]] > 1 even though [[NPV]] < 0. If, as time runs out, neither S nor X changes, then [[NPV_q]] will fall and these options will expire unexercised. But in a large sample of projects, many of them may end 'in the money'
Stars are units with a high market share in a fast-growing industry. The hope is that stars become the next cash cows. Sustaining the business unit's market leadership may require extra cash, but this is worthwhile if that's what it takes for the unit to remain a leader. When growth slows, stars become cash cows if they have been able to maintain their category leadership, or they move from brief stardom to 'dogdom'.

Part of: [[BCG Matrix]]
In probability theory and statistics, the variance is used as a measure of how far a set of numbers are spread out from each other. It is one of several descriptors of a probability distribution, describing how far the numbers lie from the mean (expected value). In particular, the variance is one of the moments of a distribution. In that context, it forms part of a systematic approach to distinguishing between probability distributions. While other such approaches have been developed, those based on moments are advantageous in terms of mathematical and computational simplicity.

!Description
Enhance your tiddlers with structured data (such as strings, booleans, numbers, or even arrays and compound objects) that can be easily accessed and modified through named fields (in JavaScript code).

Such tiddler data can be used in various applications. E.g. you may create tables that collect data from various tiddlers. 

''//Example: "Table with all December Expenses"//''
{{{
<<forEachTiddler
    where
        'tiddler.tags.contains("expense") && tiddler.data("month") == "Dec"'
    write
        '"|[["+tiddler.title+"]]|"+tiddler.data("descr")+"| "+tiddler.data("amount")+"|\n"'
>>
}}}
//(This assumes that expenses are stored in tiddlers tagged with "expense".)//
<<forEachTiddler
    where
        'tiddler.tags.contains("expense") && tiddler.data("month") == "Dec"'
    write
        '"|[["+tiddler.title+"]]|"+tiddler.data("descr")+"| "+tiddler.data("amount")+"|\n"'
>>
For other examples see DataTiddlerExamples.




''Access and Modify Tiddler Data''

You can "attach" data to every tiddler by assigning a JavaScript value (such as a string, boolean, number, or even arrays and compound objects) to named fields. 

These values can be accessed and modified through the following Tiddler methods:
|!Method|!Example|!Description|
|{{{data(field)}}}|{{{t.data("age")}}}|Returns the value of the given data field of the tiddler. When no such field is defined or its value is undefined {{{undefined}}} is returned.|
|{{{data(field,defaultValue)}}}|{{{t.data("isVIP",false)}}}|Returns the value of the given data field of the tiddler. When no such field is defined or its value is undefined the defaultValue is returned.|
|{{{data()}}}|{{{t.data()}}}|Returns the data object of the tiddler, with a property for every field. The properties of the returned data object may only be read and not be modified. To modify the data use DataTiddler.setData(...) or the corresponding Tiddler method.|
|{{{setData(field,value)}}}|{{{t.setData("age",42)}}}|Sets the value of the given data field of the tiddler to the value. When the value is {{{undefined}}} the field is removed.|
|{{{setData(field,value,defaultValue)}}}|{{{t.setData("isVIP",flag,false)}}}|Sets the value of the given data field of the tiddler to the value. When the value is equal to the defaultValue no value is set (and the field is removed).|

Alternatively you may use the following functions to access and modify the data. In this case the tiddler argument is either a tiddler or the name of a tiddler.
|!Method|!Description|
|{{{DataTiddler.getData(tiddler,field)}}}|Returns the value of the given data field of the tiddler. When no such field is defined or its value is undefined {{{undefined}}} is returned.|
|{{{DataTiddler.getData(tiddler,field,defaultValue)}}}|Returns the value of the given data field of the tiddler. When no such field is defined or its value is undefined the defaultValue is returned.|
|{{{DataTiddler.getDataObject(tiddler)}}}|Returns the data object of the tiddler, with a property for every field. The properties of the returned data object may only be read and not be modified. To modify the data use DataTiddler.setData(...) or the corresponding Tiddler method.|
|{{{DataTiddler.setData(tiddler,field,value)}}}|Sets the value of the given data field of the tiddler to the value. When the value is {{{undefined}}} the field is removed.|
|{{{DataTiddler.setData(tiddler,field,value,defaultValue)}}}|Sets the value of the given data field of the tiddler to the value. When the value is equal to the defaultValue no value is set (and the field is removed).|
//(For details on the various functions see the detailed comments in the source code.)//


''Data Representation in a Tiddler''

The data of a tiddler is stored as plain text in the tiddler's content/text, inside a "data" section that is framed by a {{{<data>...</data>}}} block. Inside the data section the information is stored in the [[JSON format|http://www.crockford.com/JSON/index.html]]. 

//''Data Section Example:''//
{{{
<data>{"isVIP":true,"user":"John Brown","age":34}</data>
}}}

The data section is not displayed when viewing the tiddler (see also "The showData Macro").

Beside the data section a tiddler may have all kind of other content.

Typically you will not access the data section text directly but use the methods given above. Nevertheless you may retrieve the text of the data section's content through the {{{DataTiddler.getDataText(tiddler)}}} function.


''Saving Changes''

The "setData" methods respect the "ForceMinorUpdate" and "AutoSave" configuration values. I.e. when "ForceMinorUpdate" is true changing a value using setData will not affect the "modifier" and "modified" attributes. With "AutoSave" set to true every setData will directly save the changes after a setData.


''Notifications''

No notifications are sent when a tiddler's data value is changed through the "setData" methods. 

''Escape Data Section''
In case that you want to use the text {{{<data>}}} or {{{</data>}}} in a tiddler text you must prefix the text with a tilde ('~'). Otherwise it may be wrongly considered as the data section. The tiddler text {{{~<data>}}} is displayed as {{{<data>}}}.


''The showData Macro''

By default the data of a tiddler (that is stored in the {{{<data>...</data>}}} section of the tiddler) is not displayed. If you want to display this data you may used the {{{<<showData ...>>}}} macro:

''Syntax:'' 
|>|{{{<<}}}''showData '' [''JSON''] [//tiddlerName//] {{{>>}}}|
|''JSON''|By default the data is rendered as a table with a "Name" and "Value" column. When defining ''JSON'' the data is rendered in JSON format|
|//tiddlerName//|Defines the tiddler holding the data to be displayed. When no tiddler is given the tiddler containing the showData macro is used. When the tiddler name contains spaces you must quote the name (or use the {{{[[...]]}}} syntax.)|
|>|~~Syntax formatting: Keywords in ''bold'', optional parts in [...]. 'or' means that exactly one of the two alternatives must exist.~~|
