a. Calculate the expected rate of return, f, for Stock B (₁ = 12%).
b. Calculate the standard deviation of expected returns, σ, for Stock A ( = 20.35%).
Now calculate the coefficient of variation for Stock B. Is it possible that most investors
will regard Stock B as being less risky than Stock A? Explain.
c. Assume the risk-free rate is 2.5%. What are the Sharpe ratios for Stocks A and B? Are
these calculations consistent with the information obtained from the coefficient of
variation calculations in part b? Explain.
