Instruction: Enter your answer Residual variance of stock A Instruction: for part b, enter your response as a decimal number rounded to four decimal places. b. Suppose that the portfolio manager follows the Treynor-Black model, and constructs an active portfolio (p) that consists of the above two stocks. The alpha of the active portfolio (p) is 18%, and its residual standard deviation is 150%. What is the Sharpe ratio for the optimal portfolio (consisting of the passive equity portfollo and the active portfollo (p)? What's the M2 of the optimal portfolio
