Abstract

We investigate the generalizability of widely perceived notions that buy-side analysts try to influence or manipulate a firm’s stock price by praising or criticizing management during a public earnings conference call. Despite two institutional factors that make it difficult to detect empirically, we find some evidence of stock influence behavior by using a combination of data on conference call transcripts and trading by the institutions that employ the buy-side analysts. However, we also find evidence consistent with the null hypothesis that buy-side analysts are acquiring information rather than manipulating the stock price. Subsample analyses suggest that stock influence is more detectable among hedge funds, while information acquisition is the norm among traditional buy-and-hold institutions. The evidence we provide on each behavior should be of interest to firm managers who host conference calls, market participants who use conference calls to collect company information, as well as regulators who monitor for possible market manipulation.
