10. You are evaluating various investment opportunities currently available and you have cal- culated expected returns and standard deviations for five different well-diversified portfo- lios of risky assets: Portfolio Q ORST U Expected Return 7.8% 10.0 4.6 11.7 6.2 Standard Deviation 10.5% 14.0 5.0 18.5 7.5 a. For each portfolio, calculate the risk premium per unit of risk that you expect to receive ([E(R)-RFR\/a). Assume that the risk-free rate is 3.0 percent. b. Using your computations in part (a), explain which of these five portfolios is most likely to be the market portfolio. Use your calculations to draw the capital market line (CML). c. If you are only willing to make an investment with = you to earn a return of 7.0 percent? 7.0 percent, is it possible for 206 Part 2: Developments in Investment Theory generate d. What is the minimum level of risk that would be necessary for an investment to earn 7.0 percent? What is the composition of the portfolio along the CML that will that expected return? e. Suppose you are now willing to make an investment with a 18.2 percent. What would be the investment proportions in the riskless asset and the market portfolio for this portfolio? What is the expected return for this portfolio?
