问题如下：
When the correlation between two stocks decreases from 0 to -1, the diversification benefit will:
选项：
A.increase.
B.decrease.
C.remain the same.
解释：
A is correct. As the correlation between two stocks decreases, diversification effect may enhance and diversification benefit will increase.
0的时候没有线性关系，-1的时候是强线性（相关）关系，照道理没有相关关系分散的效果才会更好把？

A is correct. the correlation between two stocks creases, versification effemenhananversification benefit will increase. 如果说correlation，p 从0 变成了-1 ，虽然说他们之间的相关性变的很强了，但是是inverse的，所以是对投资分散有好处，是这样理解吗？
