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 4.5%. The correlation between the risky fund retums is 0.25. The probability distributions of the risky funds are: Expected Return Standard Deviation Stock fund (S) 15% 25% Bond fund (B) 6.9% 11.5% The investment proportions for each fund in the optimal risky portfolio are W = 7273. Wg3.2727 What is the reward-to-variability (i.e., Sharpe) ratio of the best feasible CAL? O 4511 0 4315 07639 0 4221 You require that your portfolio yield an expected return of 9%, and that it be efficient on the best feasible CAL. What is the standard deviation of your portfolio? O 14.22% 11.31% 10.43% 10.99% If no risk-free asset is available. what is the standard deviation of the best possible portfolio (ie.. using only stocks and bonds) with an expected return of 9%? 15.95% 0 11.3196 10.99% 11.92%
