The following are estimates for two stocks. Stock Expected Return Beta Firm-Specific Standard Deviation A 8 % 1.00 28 % B 16 1.60 40 The market index has a standard deviation of 25% and the risk-free rate is 9%.
a. What are the standard deviations of stocks A and B? (Do not round intermediate calculations. Round your answers to 2 decimal places.)
b. Suppose that we were to construct a portfolio with proportions:
Stock A 0.25 Stock B 0.50 T-bills 0.2
5 Compute the expected return, standard deviation, beta, and nonsystematic standard deviation of the portfolio. (Do not round intermediate calculations. Enter your answer for Beta as a number, not a percent. Round your answers to 2 decimal places.)
