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 rate of 4.6%. The probability distribution of the two risky funds is as follows: Stock fund (5) Bond fund (B) Expected Return 16% 7% Standard Deviation 36% 30% The correlation between the two fund returns is 0.16. Calculate the expected return of the optimal risky portfolio. Assume that short sales of mutual funds are allowed. (Do not round intermediate calculations. Enter your answer as a decimal number rounded to 4 decimal places.)
