Much statistical analysis in finance depends on the assumption that variables have normal distributions. This assumption is far from correct. As a result, as Nassim Nicholas Taleb has rightly pointed out, most statistical results in finance are wrong. Now, a disciple of Taleb has tried to extend Taleb’s research by relating it to an obscure mathematical concept. He is successful in one area: the study of unequal distributions of wealth. In others, such as portfolio optimization and explaining insurance, less so.
