We derive a new way to test for stochastic dominance between the return of two assets using a quantile regression formulation.The test statistic is a variant of the one-sided Kolmogorov-Smirno statistic and has a limiting distribution of the standard Brownian bridge.We also illustrate how the test statistic can be extended to test for stochastic dominance among k assets.This is useful when comparing the perfor-mance of individual assets in a portfolio against some market index.
