Abstract: The purpose in this note is to demonstrate that the non-expected utility model of Markowitz implies that agents can obtain maximum expected utility from wagering all of their wealth on actuarialy unfair high probability outcomes. In order to remove this property it is necessary to assume that loss aversion tends to infinity as stake size as a proportion of wealth approaches unity.
