Suppose that the index model for stocks A and B is estimated from excess returns with the following results:
RA = 4.00% + 0.50RM + eA
RB = -1.20% + 0.70RM + eB
σM = 17%; R-squareA = 0.26; R-squareB = 0.18
Assume you create portfolio P with investment proportions of 0.70 in A and 0.30 in B. a. What is the standard deviation of the portfolio? (Do not round your intermediate calculations. Round your answer to 2 decimal places.)
b. What is the beta of your portfolio? (Do not round your intermediate calculations. Round your answer to 2 decimal places.)
