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...

We propose a novel theory that brings to light three fundamental performance drivers of zero-cost systematic investment strategies: (1) high (positive) own-asset signal-return predictability; (2) low (or negative) cross-asset signal correlation; and (3) low (or negative) cross-asset...

We document and quantify the negative impact of trend breaks (i.e., turning points in the trajectory of asset prices) on the performance of standard monthly trend-following strategies across several assets and asset classes. In the years of the U.S. economy’s expansion following the global...

Investors face a number of challenges when seeking to estimate the prospective performance of a long-only investment in commodity futures. For instance, historically, the average annualized excess return of individual commodity futures has been approximately zero and commodity futures returns...

People are more willing to bet on their own judgments when they feel skillful or knowledgeable (Heath and Tversky, 1991). We investigate whether this 'competence effect' influences trading frequency and home bias. We find that investors who feel competent trade more often and have more...

We analyze the results of the most recent survey of U.S. Chief Financial Officers (CFOs) which looks ahead to the first quarter of 2006 and beyond. We present expectations of the equity risk premium measured over a 10-year horizon relative to a 10-year U.S. Treasury bond. This multi-year survey...

The unconditional mean-variance efficiency of the Morgan Stanley Capital International world equity index is investigated. Using data from 16 OECD countries and Hong Kong and maintaining the assumption of multivariate normality, we cannot reject the efficiency of the benchmark. However, residual...

We test the mean-variance efficiency of a given portfolio with a Bayesian framework. Our test is more direct than Shanken's (1987), because we impose a prior on all the parameters of the multivariate regression model. The approach is also easily adapted to other problems. We use Monte Carlo...
