问题如下：

The return projections have been made by Eunice. an analyst from an investment company, for each of the assets with the same probability of occurrence, which combination of two equally-weighted assets has lowest diversification effect?

选项：

Asset A and Asset C.

Asset B and Asset C.

Asset A and Asset B.

解释：

C is correct.

We can also use the calculator to measure the correlation. The correlation between asset B and asset C is -1, between A and B is 0.5, and between A and C is -0.5, the higher correlation, the worse diversification.

-0.5 和 -1 为什么选-0.5呢？不是-1最分散？

嗨，努力学习的PZer你好：

这道题目问的是has lowest diversification effect，要选一个最不分散的。所以选C，是0.5的。
