Why do security analysts issue overly positive recommendations? We propose a novel approach to distinguish strategic motives (e.g., generating small-investor purchases and pleasing management) from nonstrategic motives (genuine overoptimism). We argue that nonstrategic distorters tend to issue both positive recommendations and optimistic forecasts, while strategic distorters "speak in two tongues," issuing overly positive recommendations but less optimistic forecasts. We show that the incidence of strategic distortion is large and systematically related to proxies for incentive misalignment. Our "two-tongues metric" reveals strategic distortion beyond those indicators and provides a new tool for detecting incentives to distort that are hard to identify otherwise.

Why do analysts display overoptimism about the stocks they cover? According to the selection hypothesis, analysts pick their favorite stocks and are truly too optimistic. According to the conflict-of-interest hypothesis, analysts distort their view to maximize profits via commissions and underwriting business, in particular if affiliated with an underwriting bank. We analyze the concurrent issuance of recommendations and earnings forecasts to assess the relative importance of both explanations for affiliated and for unaffiliated analysts. First, we show that recommendations and forecasts reach different audiences. Small traders follow recommendations but not forecast updates; large traders discount recommendations and follow earnings forecasts. As a result, analysts may choose to distort recommendations but prove their analyst quality in their forecasts. The selection hypothesis implies, instead, a positive correlation between recommendation and forecast overoptimism. We find that, while affiliated analysts issue more optimistic recommendations than unaffiliated analysts, their earnings forecasts are more pessimistic. Moreover, forecast optimism is negatively correlated with recommendation optimism for affiliated analysts but positively for unaffiliated analysts. Similar discrepancies between the timing of recommendations and forecasts confirm that active distortion is a major explanation for the recommendation optimism of affiliated analysts.
