Math Problem Statement
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 5.5%. The probability distributions of the risky funds are:
Expected Return Standard Deviation
Stock fund (S) 16% 36% Bond fund (B) 10% 27% The correlation between the fund returns is 0.20.
Suppose now that your portfolio must yield an expected return of 13% and be efficient, that is, on the best feasible CAL. What is the proportion invested in each of the two risky funds?

Expected Return: E(R_P) = w_S * E(R_S) + (1 - w_S) * E(R_B)
Solve for Proportion: 0.13 = 0.16 * w_S + 0.10 * (1 - w_S)
