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到-1表示相关性不是越来越强了么？分散效果不是越来越差了么？分散化的benifit不是要求相关系数的绝对值约小benifit越大么？

A is correct. the correlation between two stocks creases, versification effemenhananversification benefit will increase. 这个问题考的概念是不是就是correlation coefficient的绝对值越大，线性关系越强？

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？

A is correct. the correlation between two stocks creases, versification effemenhananversification benefit will increase. 这个题目这里，variance下降，说明组合versification分散，风险低。但是离散程度跟这个题目有关吗这两个概念有点模糊感谢回答

A is correct. the correlation between two stocks creases, versification effemenhananversification benefit will increase. 我没有看到这个概念的出现，请问分散化和离散化在这里是不是两个概念？这个vers在这里具体的含义是什么？另外，如果按照答案理解，或者您关于前面几个提问的回答，这道题是不是可以理解为\"对冲效果\"最好?
