Do investors still benefit from international diversification with investment constraints?
Author InfoChiou, Wan-Jiun Paul Lee, Alice C. Chang, Chiu-Chi A. Abstract This paper empirically investigates the potential benefits of international diversification for the U.S. investor with various investment constraints from both long-term and time-rolling perspectives. While the addition of portfolio bounds makes asset allocation more feasible, our findings suggest that adding short-selling and over-weighting constraints reduce but do not completely eliminate the diversification benefits of international investment. The over-time analyses show that diversifying portfolios internationally is still beneficial even though financial markets are becoming more integrated. The out-of-sample test suggests that the Markowitz model does not necessarily realize improved mean-variance efficiency but demonstrates risk reduction. The significant time variation in optimal asset allocation implies the necessity for the fund manager to rebalance international portfolio dynamically. Download InfoTo
