Consider portfolios formed from two risky assets, the first with expected return equal to 4 and standard deviation of its return equal to 6, the second with expected return equal to 5 and standard deviation of its return equal to 3. Let w1 denote the fraction of wealth in the portfolio allocated to asset 1, Let 1-w1 denote the fraction of wealth in the portfolio allocated to asset 2. suppose that the two asset returns are uncorrelated, so that ρ12 = 0. What is the expected return μP and the variance of the portfolio σp?
A.
μP =5+w1
σp=(w12*9+9-18W1)1/2
B.
μP =5w1
σp=(w12*45+9-9W1)1/2
C.
μP =5-w1
σp=(w12*45+9-18W1)1/2
D.
μP =5-4w1
σp=(w12*45+9-18W1)1/2
