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 4.5%. The probability distributions of the risky funds are: Stock fund (S) Bond fund (B) Expected Return 15% 9% Standard deviation 40% 31% The correlation between the fund returns is 0.15. Required: What is the expected return and standard deviation for the minimum-variance portfolio of the two risky funds? (Do not round intermediate calculations. Round your answers to 2 decimal places.) Expected return % Standard deviation % Required: Solve numerically for the proportions of each asset and for the expected return and standard deviation of the optimal risky portfolio. (Do not round intermediate calculations and round your final answers to 2 decimal places.) Portfolio invested in the stock % Portfolio invested in the bond % % Expected return Standard deviation % Required: What is the Sharpe ratio of the best feasible CAL?
