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?
