What is part b, m^2?

A portfolio manager summarizes the input from the macro and micro forecasts in the following table: icro Forecasts Asset Stock A 18 Stock B 16 Ex Return Beta Residual Standard Deviation Macro Forecasts Asset T-bills Passive Equity Portfolio (m) Return Standard Deviation 14 a. Calculate expected excess returns, alpha values, and residual variances for these stocks. Instruction: Enter your answer as a percentage (rounded to two decimal places) for expected excess returns and alpha values. Expected excess return on stock A Expected excess return on stock B Alpha of stock A Alpha of stock B 14.00 % 2.00 % -6.00 % 18.00 % Instruction: Enter your answer as a decimal number rounded to two decimal places for residual variances Residual variance of stock A 2500.00 Residual variance of stock B 2500.00 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 portfolio and the active portfolio (p))? 0.1200 What's the M2 of the optimal portfolio
