　　报告摘要如下：

　　We examine investment decisions made by mutual fund managers following the removal of corporate executives from an origin firm for positions at a new destination firm. Our results indicate that managerial turnover causes some funds to comigrate, i.e., divesting in the origin firm while initiating investments in the destination firm. This phenomenon is more pronounced for funds that have earned superior returns from the investments in the origin firm, and that have a greater demand for additional sources of information regarding the destination firm. Further, compared to the holding changes of non-comigration funds, the holding changes of comigration funds in the destination firm have more explanatory power for stock performance around earnings announcement dates. We found no evidence, however, that managers of co-migration funds have better investment skills than non-comigrating managers. Our findings indicate that institutional investors have comparative advantages in collecting certain types of information through connections with corporate executives.
