Investment returns may not follow a power law given that they can come from "normalstan". The distribution of startup values for both funded and unfunded startups (including IPOs AND failures) would come from "extremistan" due to the presence of outliers. The data from extremistan will more likely follow a power law distribution. The terms normal and exstrem-istan come from the writings of Nassim Taleb, author of Fooled By Randomness and Black Swan: Impact of the Highly Improbable.
