The relationship between β and required return is plotted on the security market line (SML), which shows expected return as a function of β. The intercept is the nominal risk-free rate available for the market, while the slope is the market premium, E(R m)− R f. The security market line can be regarded as representing a single-factor model ...
In finance, the beta (β or market beta or beta coefficient) is a statistic that measures the expected increase or decrease of an individual stock price in proportion to movements of the stock market as a whole. Beta can be used to indicate the contribution of an individual asset to the market risk of a portfolio when it is
E(R i) is an expected return on security E(R M) is an expected return on market portfolio M β is a nondiversifiable or systematic risk R M is a market rate of return R f is a risk-free rate. When used in portfolio management, the SML represents the investment's opportunity cost (investing in a combination of the market portfolio and the risk ...
Cost of equity = Risk free rate of return + Beta × (market rate of return – risk free rate of return) where Beta = sensitivity to movements in the relevant market. Thus in symbols we have = + where: E s is the expected return for a security; R f is the expected risk-free return in that market (government bond yield); β s is the sensitivity ...
r it is return to stock i in period t r f is the risk free rate (i.e. the interest rate on treasury bills) r mt is the return to the market portfolio in period t is the stock's alpha, or abnormal return is the stock's beta, or responsiveness to the market return
This required rate of return can then be used to estimate a price for the stock which can be done via a number of methods. [12] The formula for CAPM is: CAPM = (The Risk Free Rate) + (The Beta of the Security) * (The Market Risk Premium) [13] In this model, we use the implied risk premium (market return less risk-free rate) and multiply this ...

The importance of Hamada's equation is that it separates the risk of the business, reflected here by the beta of an unlevered firm, β U, from that of its levered counterpart, β L, which contains the financial risk of leverage. Apart from the effect of the tax rate, which is generally taken as constant, the discrepancy between the two betas ...
