The evidence here indicates that sovereign debt rating and credit outlook changes of one country have an asymmetric and economically significant effect on the stock market returns of other countries over 1989–2003. There is a negative reaction of 51 basis points (two-day return spread vis-á-vis the US) to a credit ratings downgrade of one notch in a common information spillover around the world. Upgrades, however, have no significant impact on return spreads of countries abroad. Closeness (e.g., geographic proximity) and emerging market status amplify the effect of a spillover. Downgrade spillover effects at the industry level are more pronounced in traded goods and small industries.

We use a new dataset to study how mutual fund flows depend on past performance across 28 countries. We show that there are marked differences in the flow-performance relationship across countries, suggesting that US findings concerning its shape do not apply universally. We find that mutual fund investors sell losers more and buy winners less in more developed countries. This is because investors in more developed countries are more sophisticated and face lower costs of participating in the mutual fund industry. Higher country-level convexity is positively associated with higher levels of risk taking by fund managers.

We compare the performance of local versus foreign institutional investors using a comprehensive data set of equity holdings in 32 countries during the 2000–2010 period. We find that foreign institutions perform as well as local institutions on average, but only domestic institutions show a trading pattern consistent with an information advantage. Our results suggest a smart-money effect of local institutions in countries subject to higher information asymmetry, non-English speaking countries, countries with less efficient stock markets, with poor investor protection, or high levels of corruption. The local advantage is more pronounced in periods of market turmoil and in illiquid stocks.
