摘要（Abstract）：

A recent strand of literature on stock market feedback examines how agents extract information from stock prices when making decisions. This paper investigates whether analysts respond to the stock-price reaction to their most recent reports. We find evidence of learning—an analyst is more likely to issue revisions and increase total recommendation activity when there is a strong stock-price reaction to their recent recommendation changes. These feedback effects are short-lived and they also exist at the broker level—brokers with more influential recommendation changes in a month become more active in revising recommendations next month. Our results imply that short-term information in recently successful reports gets incorporated with a lag to the rest of the coverage universe. A calendar-time strategy that seeks to benefit from such predictable spillover can earn abnormal returns of up to 0.6% per month.
