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 4.8%. The probability distributions of the risky funds are:

Expected Return Standard Deviation

Stock fund (S) 18% 38%

Bond fund (B) 9% 32%

The correlation between the fund returns is 0.1313.

What is the Sharpe ratio of the best feasible CAL?(Do not round intermediate calculations. Round your answer to 4 decimal places.)
