问题如下：

The benchmark is best described as appropriate if the correlation mentioned by Godwin is not statistically significantly:

选项：

A.positive. B.negative. C.different from zero.

解释：

Solution

C is correct. The correlation that Godwin mentions is between active management return and style return. Measuring this correlation identifies whether the manager’s active selection decisions, A, align with the style currently favored by the market, S. An appropriate benchmark should not reflect these systematic biases, so the correlation between A and S should not be statistically different from zero.

A and B are incorrect. The relevant correlation between A and S should not be statistically different from zero.
