Capital asset pricing model (CAPM) is a method of estimating the risks of investing in a particular stock. It is mainly used by financial analysts and investors to decide what price they should pay for a particular stock. It was first used and developed by Harry Markowitz in 1952. Harry described the relationship between an investor’s risk and the expected return in CAPM. According to Markowitz, (2008), “the expected return of a particular security or a portfolio is equal to the rate on a risk-free security plus a risk premium. If the security or portfolio does not meet or exceed the required return, then the investment should not be entered into” (pg. 91). It means that, if Stock A is riskier than Stock B, the price of Stock A should be lower to compensate investors for taking on the increased risk.Read more »
