问题如下：
An analyst calculated the excess kurtosis of a stock's returns as -0.75. From this information, we conclude that the distribution of returns is:
选项：
A.normally distributed.
B.thin-tailed compared to the normal distribution
C.fat-tailed compared to the normal distribution
解释：
B is correct. The distribution is thin-tailed relative to the normal distribution because the excess kurtosis is less than zero.
