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 5.7%. The probability distributions of the risky funds are:

	Expected Return	Standard Deviation
Stock fund (S)	18%	47%
Bond fund (B)	7%	41%

The correlation between the fund returns is 0.0317.

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