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 5.4%. The probability distributions of the risky funds are:

stock fund s: expected return 15% standard deviation 44%

bonds funds b: expected return 8% standard deviation 38%

the correlation between the fund returns is 0.0684

What is the sharpe ratio of the best feasible CAL? (do not round intermediate calculations. Round your answer four decimal places.)
