You manage an equity fund with an expected risk premium of 13.2% and a standard deviation of 46%. The rate on Treasury bills is 4.6%. Your client chooses to invest $105,000 of her portfolio in your equity fund and $45,000 in a T-bill money market fund. What is the reward-to-volatility (Sharpe) ratio for the equity fund? (Round your answer to 4 decimal places.)
Weight of Equity in Portfolio =105000/(105000+45000) =70%
Weight of T-bill money=45000/(105000+45000)=30%
Expected Return on equity =13.2%+4.6% =17.80%
Return on portfolio =Weight of Equity*Cost of Equity +Weight of
Risk Free Asset*Cost of Risk free asset
=70%*17.80%+30%*4.6% =13.84%
Standard Deviation of Risk free asset =0
Standard Deviation of Portfolio =((Weight of Equity*Standard
Deviation of Equity)+(Weight of Risk free asset*Standard Deviation
of risk free asset))^2 =((70%*46%)^2+(30%*0%)^2)^0.5 =32.20%
Reward to Risk ratio =(Return on portfolio-Risk free rate)/Standard
Deviation =(13.84%-4.6%)/32.20%
=0.2870
