assume that you manage a risky portfolio with an expected rate of return of 18 % and a standard deviation of 26%. The T-bill rate is 7%.

4. A pension fund manager is considering three mutual funds. The first is a stock fund, the second is a long-term government and corporate bond fund, and the third is a T-bill money market fund that yields a sure rate of 5%. The probability distributions of the risky funds are: Expected Return Standard Deviation Stock fund (S) 15% 32% Bond fund (B) 10% 23% The correlation between the fund returns is 0.25. a. Tabulate and draw the investment opportunity set of the two risky funds. Use investment proportions for the stock fund of 0% to 100% in increments of 10%. What expected return and standard deviation does your graph show for the minimum- variance portfolio? Use the Excel template I post on Blackboard. b. Draw a tangent from the risk-free rate to the opportunity set. What does your graph show for the expected return and standard deviation of the optimal risky portfolio? c. What is the Sharpe ratio of the best feasible CAL? 4. A pension fund manager is considering three mutual funds.
