5. You are evaluating the performance of two portfolio managers, and you have gathered annual return data for the past decade: Manager X Return (%) Manager Y Return (%) Year -6.5 -1.5 -1.5 -3.5 -1.5 3 -1.5 4 -1.0 3.5 0.0 4.5 4.5 6.5 6.5 7.5 8.5 8.5 13.5 12.5 10 17.5 13.5 a. For each manager, calculate (1) the average annual return, (2) the standard deviation of returns, and (3) the semi-deviation of returns. b. Assuming that the average annual risk-free rate during the 10-year sample period was 1.5 percent, calculate the Sharpe ratio for each portfolio. Based on these computations, which manager appears to have performed the best? c. Calculate the Sortino ratio for each portfolio, using the average risk-free rate as the minimum acceptable return threshold. Based on these computations, which manager appears to have performed the best? d. When would you expect the Sharpe and Sortino measures to provide (1) the same per- formance ranking or (2) different performance rankings? Explain.
