Use the mean return and standard deviation of return (using the 90 annual returns) as the proxy for the risky portfolio’s expected return and risk. It turns out to be 12.0% and 19.9%.

Assume the latest annualized risk-free rate of return = 4%. Assume that the market portfolio is the proxy for the optimal risky portfolio. Assume correlation of market’s return with the risk-free return = 0.

c) What is the slope of CAL? How is it related to the Sharpe Ratio of the market portfolio?
