I have a question about this article Is it possible to combine all four degree of stochastic dominance to select candidate stocks in a momentum arbitrage portfolio and consider a final rank for the stock based on the amount of stochastic dominance of all four degree of  stochastic dominance  ? Is their work rational? Does each degree of  stochastic dominance   represent the preferences of each class of utility functions? If yes, then if all four  degree   are considered together in stock selection, it is as if the absolute risk aversion preferences of decreasing (DARA)  and increasing (IARA) and non-satiable have been merged into one bowl, or in other words, they have been merged together.
