Assignment:
You manage a risky portfolio with an expected rate of return of 16% and a standard deviation of 27%. The T-bill rate is 7%.
Questions:
a. Your client chooses to invest 80% of a portfolio in your fund and 20% in an essentially risk-free money market fund. What are the expected value and standard deviations of the rate of return on his portfolio?
b. Suppose that your risky portfolio includes the following investments in the given proportions: Stock A 25% Stock B 30% Stock C 45% What are the investment proportions of your client's overall portfolio, including the position in T-bills?
c. What is the reward-to-volatility (Sharpe) ratio (S) of your risky portfolio? Your client's?
d. Draw the CAL of your portfolio on an expected return-standard deviation diagram. What is the slope of the CAL? Show the position of your client on your fund's CAL.
Consider three client's preferences and scenarios in parts e to g:
e. Suppose that your client decides to invest in your portfolio a proportion y of the total investment budget so that the overall portfolio will have an expected rate of return of 14%.
(i) What is the proportion y?
(ii) What are your client's investment proportions in your three stocks and the T-bill fund?
(iii) What is the standard deviation of the rate of return on your client's portfolio?
f. Suppose that your client prefers to invest in your fund a proportion y that maximizes the expected return on the complete portfolio subject to the constraint that the complete portfolio's standard deviation will not exceed 18%.
(i) What is the investment proportion, y?
(ii) What is the expected rate of return on the complete portfolio?
g. Your client's degree of risk aversion is A = 5. Your client's expected utility function is assumed to be 1 2 ( ) 2 E U E r A (i) What proportion, y, of the total investment should be invested in your fund? (ii) What are the expected value and standard deviation of the rate of return on your client's optimized portfolio?
