Sell-Side Analysts and Stock Mispricing: Evidence from Mutual Fund Flow-Driven Trading Pressure
利用共同基金极端流量驱动的交易压力，研究发现部分分析师通过发布价格修正建议来稳定市场，这些建议伴随较小的盈利预测变化，且能缓解流动性恶化、加速价格修正。
Using the setting of extreme mutual fund flow-driven trading pressure, this paper examines sell-side analysts’ role in stabilizing capital markets. We find that a select group of analysts persistently issue price-correcting recommendation changes for stocks experiencing mutual fund flow-driven mispricing. Such recommendation changes are accompanied by little change to their concurrent earnings forecasts and appear to be driven by the superior research skill of these “mispricing-sensitive” analysts. Stocks receiving price-correcting recommendation changes experience less severe liquidity deterioration, more immediate price correction, and consequently smaller subsequent long-run return reversal. Our findings highlight analysts’ unique role in facilitating liquidity provision and stabilizing capital markets during severe mispricing events. This paper was accepted by Neng Wang, finance.
