This study establishes necessary conditions for Almost Stochastic Dominance criteria of various orders. These conditions take the form of restrictions on algebraic combinations of moments of the probability distributions in question. The relevant set of conditions depends on the relevant order...

We investigate whether the use of component forecasts improves the accuracy of a portfolio forecast which uses only aggregate data. The results show that the use of component data improves the accuracy of aggregate forecasts. Furthermore, the long–short trading strategy based on the component...

Both the expected-utility maximization and the hierarchy property are very important properties in stochastic dominance. For almost stochastic dominance, Leshno and Levy (2002) propose a definition and Tzeng et al. (2013) modified it to give another definition. This note provides more...
