Investors act rational and choose their portfolio solely based on the expected return and its standard deviation over that period, which means that returns have to be normally distributed Wilhelm,p. Alongside stocks, the market portfolio actually contains real estate and other risky assets, even human capital.

The CAPM suffers from a number of disadvantages and limitations that should be noted in a balanced discussion of this important theoretical model. Assigning values to CAPM variables In order to use the CAPM, values need to be assigned to the risk-free rate of return, the return on the market, or the equity risk premium (ERP), and the equity beta.

The Advantages And Disadvantages Of The CAPM Model The capital asset pricing model (CAPM) is a widely-used finance theory that establishes a linear relationship between the required return on.
