问题如下：

Based on Exhibit 1, the proportion of Manager C’s total portfolio variance contributed by Asset 2 is closest to:

选项：

A.

0.0025.

B.

0.0056.

C.

0.0088.

解释：

B is correct. The contribution of an asset to total portfolio variance equals the summation of the multiplication between the weight of the asset whose contribution is being measured, the weight of each asset (xj), and the covariance between the asset being measured and each asset (Cij), as follows:

Contribution of each asset to portfolio variance = CVi

=∑j=1nXjXiCi,j={\textstyle\sum_{j=1}^n}X_jX_iC_{i,j}

The contribution of Asset 2 to portfolio variance is computed as the sum of the following products:

请问这个计算是在哪个知识点里的？

这道题是归在R25啊，你这边看在R24吗？

嗨，努力学习的PZer你好：


请看基础班视频Allocating The Risk Budget对应讲义241页，这里部分的例题和课后题是一样的，建议先去听下李老师的讲解再来做题。

虽然现在很辛苦，但努力过的感觉真的很好，加油！

这道题问的是proportion，是不是还得除以总风险？感觉答案给的是contribution的数字呢？ 到底什么问法是除以总风险的结果，什么问法是不用除呢？
