When the correlation between two stocks decreases from 0 to -1, the diversification benefit will:

选项:

A.

increase.

B.

decrease.

C.

解释:

A is correct. As the correlation between two stocks decreases, diversification effect may enhance and diversification benefit will increase.

diversification benefit是指真实的收益还是分散效果?分散化效果好这个知识点在讲义里有吗?恳请指教。

同学你好,

直译成“分散化的好处”即可。

如果以组合的形式投资,会因为资产之间的的彼此对冲而降低风险,这就是分散化。

当相关系数(correlation) ρ=+1,无分散化效果;当ρ=-1时分散化效果最好。分散化效果从+1到-1逐渐增强。

可以从计算两资产组合的方差公式中看出来,当ρ= -1时,组合方差最小,即分散化效果最好。这个知识点更多的会在组合里考
