The hypothesis that financial variables are normally distributed is often rejected in both theoretical studies and extremely specific cases. In the ”real” world of financial investors – where risk averse agents mainly hold government bonds, a few equities and do not hold derivatives – the normal distribution still plays a lead role. To show this result, in this paper we focus on a number of efficient portfolios subject to several constraints which make them close to the portfolios held by most of financial agents. A multivariate approach is proposed, which refers to the case of a financial asset manager who cannot only pay attention to the average return of all of his portfolios, but must evaluate the risks associated to each of his portfolios jointly.
