""We evaluate the performance of U.S. investors' international portfolios over a 25-year period. Portfolio returns are formed by first estimating monthly bilateral holdings in 44 countries using high-quality but infrequent benchmark surveys that enable us to eliminate the geographical bias in reported capital flows data. In their foreign equity portfolios, U.S. investors achieved a significantly higher Sharpe ratio than global benchmarks, especially since 1990. We uncover three potential reasons for this success. First, they abstained from returns-chasing behavior and instead sold past winners. Second, conditional performance tests provide no evidence that the superior (unconditional) performance owed to private information, suggesting that the successful exploitation of publicly available information played a role. Third, well-documented preferences for cross-listed and well-governed foreign firms appear to have served U.S. investors well. We also evaluate the unconditional performance of bond portfolios, about which less information is available, and find that U.S. investors achieved higher Sharpe ratios than global benchmarks, although the difference here is not statistically significant"--Federal Reserve Board web site."
"This paper evaluates the ability of U.S. investors to allocate their foreign equity portfolios across 44 countries over a 25-year period. We find that U.S. portfolios achieved a significantly higher Sharpe ratio than foreign benchmarks, especially since 1990. We test whether this strong performance owed to trading expertise or longer-term allocation expertise. The evidence is overwhelmingly against trading expertise. While U.S. investors did abstain from momentum trading and instead sold past winners, we find no evidence that these past winners subsequently underperformed. In addition, conditional performance measures, which directly test reallocating into (out of) markets that subsequently outperformed (underperformed), suggest no significant trading expertise. In contrast, we offer strong evidence of longer-term allocation expertise: If we fix portfolio weights at the end of 1989 and do not allow reallocations, we still find superior performance in the recent period."
