Hello, Can you guys help me with the following: E(R) for Fund A is 19 with Standard Devitation of 33 E(R) for Fund B is 8 with Standard Devitation of 13 The colleration between the two funds is .10. If the investor requires a portfolio return of 12%, what should be the proportions for each fund? Actually how do you find w1 and w2, because the formula requiers the w1 and w2 figures? Thank you in advance!! |

With the basic formula for portfolios with 2 assets you can deduce a direct formula for w1 by replacing w2 = 1 - w1 as: w1 + w2 = 1 E(Rp) = w1*E(R1) + w2*E(R2) Replacing: E(Rp) = w1*E(R1) + ( 1 - w1 )*E(R2) -> 0.12 = w1*0.19 + ( 1 - w1 )*0.08 -> w1 = 0.364 -> w2 = 1 - w1, w2 = 0.636 Now, this is the formula to calculate weights in the point know as the global minimum-variance portfolio (the point where efficient frontier begins): w1 = ( Variance2 - Cov1,2 ) / ( Variance1 + Variance2 - 2*Cov1,2 ) w2 = 1 - w1 |

I am happy to say that I passed! Your study notes certainly helped prepare me for what was the most difficult exam I had ever taken.
