a) For each of the cases shown in the following table, use the capital asset pricing model (CAPM) to find the required return and explain your answer. Case Risk-free rate (%) Market return (%) Beta A 5 8 1.3. B 8 13 0.9 C 9 12 -0.2 D 10 15 1.0 E 6 10 0.6 (16 marks) b) Use the basic equation for the CAPM to rework each of the following problems for above case. Case A) Find the required return for an asset with a beta of 0.9 when the risk-free rate and market return are 8% and 12% respectively. Case B) Find the risk-free rate for a firm with a required return of 15% and a beta of 1.25 when the market return is 14%. Case C) Find the market return for an asset with a required return of 16% and a beta of 1.1 when the risk-free rate is 9%. Case D) Find the beta for an asset with a required return of 15% when the risk-free rate and market return are 10% and 12.5% respectively. (16 marks) c) Describe the advantages of using CAPM model to determine the expected return. (8 marks)
