negatively skewed distribution... return, median

eyiqiong

A negatively skewed distribution is characterized by many small gains and a few extreme losses. Note that kurtosis is a measure of the peakedness of a return distribution.

在negatively skewed distribution中 mean<median<mode，仿佛不符合many small gains and a few extreme losses的说法，怎么理解？

kurtosis is a measure of the peakedness of a return distribution。怎讲？
