In 1999, former Michigan Ross finance faculty member Josh Coval co-authored a paper that is among the top 50 most-cited papers in finance. The paper shows one of the most intriguing patterns in individual behavior. The strong bias in favor of domestic securities is a well-documented characteristic of international investment portfolios, yet this paper shows that the preference for investing close to home also applies to portfolios of domestic stocks. Specifically, U.S. investment managers strongly prefer locally headquartered firms, particularly small, highly leveraged firms that produce nontraded goods. These results suggest that asymmetric information between local and non-local investors may drive the preference for geographically proximate investments, and the relation between investment proximity and firm size and leverage may shed light on several well-documented asset pricing anomalies.
