Abstract

"Sell-side"analysts advise fund managers with recommendations to buy or sell a stock. But being compensated with commissions proportional to the amount traded can drive the analyst to bias his advice. In a two-agent model, it is notably shown that the probability of a biased equilibrium to occur increases with commission rate, but decreases with the weight of analyst rating. Moreover, the fund manager can cross-check the recommendation with his own signal–this may represent access to an in-house"buy-side analyst". The fund manager does not necessarily follow the sell-side analyst if its own signal is precise enough . The model hence provides a theoretical rationale for recent empirical results about the independance of sell-side analysts.
