International Stock Return Predictability under Model Uncertainty

By Andreas Schrimpf

Abstract

This paper examines return predictability when the investor is uncertain about the right state variables. A novel feature of the model averaging approach used in this paper is to account for finite-sample bias of the coeffcients in the predictive regressions. Drawing on an extensive international dataset, we find that interest-rate related variables are usually among the most prominent predictive variables, whereas valuation ratios perform rather poorly. Yet, predictability of market excess returns weakens substantially, once model uncertainty is accounted for. We document notable differences in the degree of in-sample and out-of-sample predictability across diferent stock markets. Overall, these findings suggests that return predictability is not a uniform and a universal feature across international capital markets
