Mixing both effects into a single blended alpha signal forms a stronger country and industry selection method. An equal-weighted strategy that simultaneously goes long the indexes with the highest short-term and the lowest long-term alphas and shorts the ones with the lowest short-term and highest long-term alphas yields monthly three-factor model alphas of 1.16% and 1.44% for countries and industries respectively. The results are robust to alternative weighting schemes the effect of trading costs alternative alpha models and controlling for popular return predictive variables. © 2020 Elsevier B.V.
