Traditional mean-variance efficient portfolios do not capture the potential wealth creation opportunities provided by predictability of asset returns. We propose a simple method for constructing optimally managed portfolios that exploits the possibility that asset returns are predictable. We...

This Paper assesses the ability of international asset pricing models to explain the cross-sectional variation in expected returns. All the models considered seem to capture national market returns fairly well. Global portfolios sorted on earnings-price ratio and market value, however, pose a...

It is well known that the interest rate differential predicts currency returns. However, we argue in a present-value model that the real exchange rate is also key to understanding currency returns. We find that a missing risk premium, which is closely related to the real exchange rate, explains...
