The impact of sell-side analyst research coverage on an affiliated broker's market share of trading volume

Abstract

Using NASDAQ reported individual stock level trading volume, we find that analyst research coverage on a stock increases the level of an affiliated broker's market share of trading volume in that stock by 0.8 percent, on average, which corresponds to an additional annual volume of about one million shares in an average stock. Optimistic recommendations increase the level of market share by an additional 0.3 percent, on average, which is consistent with the notion that analysts have an incentive to issue optimistic recommendations. Also, a broker's market share of volume increases on average when an affiliated analyst changes his/her recommendation, and decreases with the length of time during which an analyst maintains the same recommendation on a stock. The latter findings suggest that sell-side institutions are rewarded for providing new information to the market and for ongoing research services.
