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...

The authors first discuss performance evaluation using stochastic discount factors and relate it to traditional mean-variance analysis. They then use Monte Carlo experiments to examine the properties of various general method of moment (GMM) estimators. The test statistics are fairly well...
