Suppose that the index model for stocks A and B is estimated from excess returns with the following results: RA = 3.50% + 0.65RM + eA RB = -1.60% + 0.80RM + eB σM = 21%; R-squareA = 0.22; R-squareB = 0.14 Assume you create a portfolio Q, with investment proportions of 0.50 in a risky portfolio P, 0.30 in the market index, and 0.20 in T-bill. Portfolio P is composed of 60% Stock A and 40% Stock B. Required: What is the standard deviation of portfolio Q?
