We study the impact of parameter uncertainty on the expected utility of a multiperiod investor subject to quadratic transaction costs. We characterize the utility loss associated with ignoring parameter uncertainty, and show that it is equal to the product between the single-period utility loss...

This paper examines the patterns of intraday cojumps between international equity markets as well as their impact on international asset holdings and portfolio diversification benefits. Using intraday index-based data for exchange-traded funds as proxies for international equity markets, we...

This paper provides a comprehensive analysis of portfolio choice with popular foreign exchange (FX) investment styles such as carry trades and strategies commonly known as FX momentum, and FX value. We investigate if diversification benefits can be achieved by style investing in FX markets...

We investigate the effects of bull and bear markets on correlations between developed and emerging country equity returns, and on the benefits of combining international markets in a portfolio. We find that, contrary to most other studies, correlations fall in both bull and bear markets,...

We develop a directional trading model and a crisis management model to measure fund manager skills more adequately. We test the robustness of both traditional market timing models and new management skill models to changes in their underlying investor utility function and excess return...
