The mean values of skewness and kurtosis coefficients are close to zero for all variables, indicating symmetrical and mesokurtic distribution, respectively, despite the asymmetry indicated by the Anderson-Darling test.
Thus, the longer the block of days measured for market returns, the closer the empirical distributions of the countries under study approximated a symmetrical and mesokurtic distribution.
