**CFA Practice Question**

You are examining a portfolio composed of 33% money-market investments, 9.5% bonds, and 57.5% stocks. Last year, the return on the money-market investments was 4%, the return on bonds was 9%, and the return on stocks was -11%. What is the contribution of stocks toward the portfolio weighted average return?

A. -57.50%

B. -11.00%

C. -6.325%

**Explanation:**The portfolio weighted average mean return is equal to the sum (as i goes from 1 to n) of w_i * X_i, where w_i is the percentage weight in the portfolio of the ith asset, and X_i is the investment return of the ith asset. The contribution of any asset will equal its weight in the portfolio multiplied by its return. Here, we get 0.575 * - 0.11 = -6.325%.

Calculate the absoulte contribution and not the relative contribution. |

i don't get this problem. i get 4.15% = (0.33*0.04) + (0.095*0.09) + (0.575*-0.11) |

Tricky: not ask for WACC |

very tricky....i like it: This portfolio has 3 components: 1.Stock 2.Money Market and 3.Bonds.. The question clearly asks for the contribution of the STOCKS to this portfolio - which is 0.575 X (-11) = -6.325 ....isin't it a nice question. :) |
