问题和答案不对应？

  1. CFA I
  2. Quantitative

NO.PZ2018062016000056

问题如下：

Given the table above, which of the following statements is least accurate regarding to the skewness of Stock C?

选项：

A.

The return distribution has a few extreme gains.

B.

The return distribution has a few extreme losses.

C.

The mean return is larger than its median.

解释：

B is correct. The skewness of Stock C is positive,which shows right fat tails. A positive skewed distribution has frequent small losses and a few extreme gains.

这个题目和答案 是不是还是不对应啊？stock c的skewness大于0，不就是positive skewed吗？那么 不应该是 a few extreme gains吗？选A，为啥给的答案是B呢？
