Capital asset pricing model CAPM

The normal method of calculation for company funds is to use the capital asset pricing model (CAPM). This was developed by share analysts keen to have a defence against accusations of negligence in selecting shares for clients as a means of assessing the real value of any share, in the form of risk and desirability. It essentially demonstrates one version of the direct proportionality between risk and return. 

The first is the Cost of Equity. It is defined here as the return that a shareholder expects from the company over a certain period, in terms of dividend and the capital gain from a rise in the stock price. These are the actual expectations of income on which an investor bases his original purchase or reviews his portfolio. The Cost of Equity can be estimated using the Capital Asset Pricing Model (CAPM). 

Another very popular definition of risk is through the risk premium or beta. This is defined as the slope of the curve that gives market returns as a function of S P 500 Index returns in other words, comparing how the investment compares with the market. The concept of beta (the slope of the curve) is part of the capital asset pricing model (CAPM) proposed by Lintner (1969) and Sharpe (1970), which intends to incorporate risk into valuation of portfolios and it can also be viewed as the increase in expected return in exchange for a given increase in variance. However, this concept seems to apply to building stock portfolios more than to technical projects within a company. 

If the equity value is estimated by using the discounted cash flow method, the cost of capital assumes a particular relevance. Conventionally, the cost of capital is estimated through the capital asset pricing model (CAPM) that was introduced by Sharpe (1964) and subsequently improved by Lintner (1965). One of the most important variables is beta. Beta measures the sensitivity of the asset s or company returns to variation in the market or index returns. Therefore, according to CAPM theory, the risk assumed from an investor depends on the covariance (or correlation) between individual assets and market portfolio. Thus, if these singular assets do not have correlation, they will not add risk differently, if the correlation is positive they will add risk on market portfolio. 

To compute the expected return on equity, which is denoted by E ROE),Vx. (2.50) is applied. In this expression, E (ROE) is computed as the sum of a risk free rate and a risk premium (cpRe). The former term represents the rate of return of an investment free of default risk available in the market and is usually equal to the yield to maturity offered by a government security. The latter, represents the expected amount of return above the risk-free rate in exchange for a given amount of variance (Pratt 2002, Applequist et al. 2000). One of the most commonly employed methods to estimate the risk premium is the Capital Asset Pricing Model (CAPM). For more details regarding this topic the reader is referred to Sharpe (1999).
