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 4.3%.

The probability distributions of the risky funds are: Expected Return Standard Deviation Stock fund (S) 13% 34% Bond fund (B) 6% 27%

The correlation between the fund returns is 0.0630.

What is the Sharpe ratio of the best feasible CAL?
