Consider the following two-factor model for the returns of three well-diversified assets (i.e., with no idiosyncratic risk): = 0.12 +6F₁ +4F2, 0.04 + 1F₁+2F2, 0.01 - 1F₁ + 3F2. ΤΑ TB = rc = (a) (10 points) Compute the expected return of factor replicating portfolio 1 (FRP1), the expected return of factor replicating portfolio 2 (FRP2), and the risk-free rate. [Note: Recall that FRP1 has b1,FRP1 = 1, b2,FRP1 = 0 and FRP2 has b₁,FRP2 = 0, b2,FRP2 = 1.] (b) (5 points) Assume that we have a new asset, asset D (also with no idiosyncratic risk), with exposures plus 1 to factor 1 (F₁) and plus 2 to factor 2 (F2). What is its expected return? (c) (5 points) Assume that the standard deviation of factor 1 is 11%, the standard deviation of factor 2 is 5%, and the standard deviation of D is 25%. Additionally, relax earlier assumption and assume D might have idiosyncratic risk. What the standard deviation of the idiosyncratic risk in portfolio D? Make sure you justify each step in this calculation. (d) (10 points) What are the Sharpe Ratios of assets FPR1, FRP2, and D?
