Manipulating CAPM Use the basic equation for the capital asset pricing model (CAPM) to work each of the following problems. a. Find the required return for an asset with a beta of 0.63 when the risk-free rate and market return are 9% and 13%, respectively. b. Find the risk-free rate for a firm with a required return of 21.011% and a beta of 1.64 when the market return is 16%. c. Find the market return for an asset with a required return of 11.097% and a beta of 0.98 when the risk-free rate is 8%. d. Find the beta for an asset with a required return of 12.752% when the risk-free rate and market return are 5% and 11.8%, respectively. Capital asset pricing model (CAPM) For each of the cases shown in the following table, use the capital asset pricing model to find the required return.
