讲座主题： Mutual fund affiliated analysts and stock price synchronicity
摘要：mutual fund affiliated analysts have conflicts of interests in their role of information production. Many times, they strategically speak in two tongues: issue optimism biased recommendations but less optimistic forecasts for their covered firms (Malmendier and Shanthikumar, 2014, “Do security analysts speak in two tongues?” Review of Financial Studies, 27, 1287-1322). It is not clear what the net effect of these affiliated analysts’ conflicting actions is on firm-specific information production in the stock market. We use a unique Chinese dataset that discloses the business affiliations between mutual funds and brokerage firms through commission allocations to examine whether affiliated analysts produce more (or less) firm-specific information in their research compared with non-affiliated analysts. Our results indicate that affiliated analysts produce more firm-specific information, manifested by lower stock price synchronicity for the firms they cover. The results are robust to alternative specifications of variables and models, after controlling for other types of affiliations such as full service security and brokerage firm affiliations, and after addressing possible endogeneity concerns. We further find that the affiliated analyst effects are more pronounced for stocks that represent significant exposure to an affiliated mutual fund’s investment, where mutual funds presumably need more firm-specific information to make investment decisions. Finally, we document that affiliated analysts do more site visits on the stocks held by their mutual fund clients, which provides explanation for the greater information dissemination by affiliated analysts.
