hi, can someone tell me why the Nky skew is much smaller than FTSE? THANKS

Hi there,I assume that you are referring to the skewness of the index returns hence my answer:The nikkei returns were smaller than those of the ftse over your sample period hence the return of the nky is/was smaller than that of the ftse - or in other words closer to zero on the x-axis. (ftse had higher returns than the nky)In short a normal distribution that is not skewed is equally distributed around zero.With skewness to the right the overall returns over your sample period are positive.Given a skewness to the left during your sample period the index returns were negative.

i mean the vol skew...is that because nky has been decreased in spot for many years?can somebody pls advise?
