|March 2014||Uncovered Equity Parity and Rebalancing in International Portfolios|
with Stephanie E. Curcuru, Charles P. Thomas, Francis E. Warnock: w19963
Portfolio rebalancing is a key driver of the Uncovered Equity Parity (UEP) condition. According to UEP, when foreign equity holdings outperform domestic holdings, domestic investors are exposed to higher exchange rate exposure and hence repatriate some of the foreign equity to decrease their exchange rate risk. By doing so, foreign currency is sold, leading to foreign currency depreciation. We examine the relationship between U.S. investors' portfolio reallocations and returns and find some evidence consistent with UEP: Portfolio shifts are related to past returns in the underlying equity markets. But we argue that a motive other than reducing currency risk exposure is likely behind this rebalancing. In particular, U.S. investors may be exploiting mean reversion in underlying equity market...

with Stephanie E. Curcuru, Charles P. Thomas, Francis E. Warnock: w16677
Counter to extant stylized facts, using newly available data on country allocations in U.S. investors' foreign equity portfolios we find that (i) U.S. investors do not exhibit returns-chasing behavior, but, consistent with partial portfolio rebalancing, tend to sell past winners; and (ii) U.S. investors increase portfolio weights on a country's equity market just prior to its strong performance, behavior inconsistent with an informational disadvantage. Over the past two decades, U.S. investors' foreign equity portfolios outperformed a value-weighted foreign benchmark by 160 basis points per year.

|July 2006||The Performance of International Equity Portfolios|
with Charles P. Thomas, Francis E. Warnock: w12346
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 stron...
