这题可以用volatility来解释吗~
NO.PZ201809170400000508 问题如下 Whirisk measure es Fun3’s new risk control explicitly constrain? Volatility Skewness awwn B is correct. Skewness measures the gree to whireturn expectations are non-normally stribute If a stribution is positively skewe the meof the stribution is greater thits mean—more thhalf of the viations from the meare negative anless thhalf are positive—anthe average magnitu of positive viations is larger ththe average magnitu of negative viations. Negative skew incates thththe meof the stribution lies below its mean, anthe average magnitu of negative viations is larger ththe average magnitu of positive viations. Fun3’s new risk control constrains its mol’s prectereturn stribution so thno more th60% of the viations from the meare negative. This is explicit constraint on skewness. If a stribution is positively skewe the meof the stribution is greater thits mean—more thhalf of the viations from the meare negative anless thhalf are positive—anthe average magnitu of positive viations is larger ththe average magnitu of negative viations. Negative skew incates thththe meof the stribution lies below its mean, anthe average magnitu of negative viations is larger ththe average magnitu of positive viations. Fun3’s new risk control constrains its mol’s prectereturn stribution so thno more th60% of the viations from the meare negative. 老师好，一级知识全忘了，上面划线部分没读懂，我知道右偏的memean和mo，但其他理解不了，麻烦下，谢谢

请问awwn为什么不对，不是说no more th60% the viations from the meare negative?也就是最大回撤不超过60%
