We examine the relation between country and industry portfolio concentration and performance using a data set of international equity mutual funds. When sorted by concentration measures, funds in the most concentrated quintile outperform those in the most diversified quintile by 0.16% and 0.30% monthly in country and industry dimensions, respectively. Further analysis shows that the superior performance of concentrated funds is largely driven by industry rather than country concentration, suggesting the existence of global industry private information. Finally, we show that industry-concentrated funds rotate top-holding industries less frequently than their diversified counterparts, and that the industries these funds purchase subsequently outperform the industries they sell.

This paper examines the impact of social trust on stock price crash risk. Social trust measures the level of mutual trust among the members of a society. Using a large sample of Chinese listed firms for the 2001–2015 period, we find that firms headquartered in regions of high social trust tend to have smaller crash risks. This result is robust to a battery of sensitivity tests and is more prominent for State-Owned Enterprises (SOEs), for firms with weak monitoring, and for firms with higher risk-taking. Moreover, we observe that firms in regions of high social trust are associated with higher accounting conservatism and fewer financial restatements. Our study suggests that social trust is an important variable that is omitted in the literature investigating the predictors of stock price crashes.

We examine stock and bond market reactions to the key events leading to the passage of the Dodd–Frank Act to assess the markets’ expectations about the effectiveness of the Act on systemically important financial firms. Using small/medium sized domestic financial institutions as a control group, we find that large financial institutions overall had negative abnormal stock returns and positive abnormal bond returns, suggesting that the markets expect the Act to be effective in reducing these banks’ risk-taking. We further investigate the market reactions for (1) larger and more interconnected financial institutions; and (2) the Big 6 banks to evaluate the markets’ assessment about the effectiveness of the act in ending the too-big-to-fail policy. We document that larger and more interconnected financial institutions experienced more negative abnormal stock returns and more positive abnormal bond returns as compared to other banks in our sample, but these relations are not present during the final phase of the passage. Likewise, we find that both shareholders and bondholders of the Big 6 banks initially experienced significant negative returns, followed by insignificant returns during the final phase of the passage. These results appear to suggest the markets are doubtful about the effectiveness of the final version of the bill to end the too-big-to-fail status in particular for the Big 6 banks.
