One widely used version of the CAPM model (as we learned in class) is as follows: Risk premium of a stock = Pintercept + B. Market risk premium + Risk premium of a stock: the risk-free rate adjusted return of the stock (It is the cost of capital minus the risk-free rate). Market risk premium: the risk-free rate adjusted return of the market (e.g., S&P 500). The slope of the regression line, B1 is the relative volatility (beta), a measure of sensitivity of the return of an individual asset with respect to the market return. Stocks with higher beta's (e.g., B1 > 1) are considered to be riskier than stocks with lower betas (e.g., B1 1) are considered to be riskier than stocks with lower betas (e.g., B1
