We present evidence of the impact of buy-side analysts on the behavior and performance of fund managers. Using data provided by a large global asset manager, we relate buy-side analysts' recommendations to fund transactions on a daily basis. Our results show that buy-side analysts have a significant influence on trading decisions: Fund managers almost certainly follow recent recommendation revisions in their trades. Fund flows and sell-side recommendations matter as well, but to a lesser extent. Positive abnormal returns to buy-side analysts' revisions are also reflected in the performance of mutual fund trades: trades triggered by buy-side recommendations have higher returns than other trades.
