Motivated by research in psychology and experimental economics, we assume that investors update their beliefs about an asset's value upon observing the price, but only when the price clearly reveals that others obtained private information that differs from their own private information. In...

We investigate the type of information text sentiment uncovers using earnings conference call transcripts and find that text sentiment fails to explain returns during intraday calls, while average trading volume and return volatility are higher during the call. This finding indicates that...

This study constructs the institutional- and individual-based probability of informed trading (PIN) by adjusting Easley, Hvidkjaer and O'Hara (2002) and investigates the impact of the informed trading behaviors of institutions and individuals on the post-announcement drift around the earnings...

I study how investor horizons affect the price reaction of the stocks to earnings announcements. In the theory, short-run investors trade frequently, while long-run traders hold and trade on fundamentals. The model predicts that the reaction to an earnings announcement is shifted downward for...

This study investigates individual and institutional trading in competing firms around earnings announcements. We find individual and institutional informed trading in competing firms, which is dominant prior to earnings announcements. Magnitude of institutional (individual) net order flow...

Post-earnings-announcement drift (PEAD) is one of the most solidly documented asset pricing anomalies. We use the controlled conditions of an experimental lab to investigate whether earnings autocorrelation is the driving cause of this anomaly. We observe PEAD in settings with uncorrelated and...

Using a unique database this study establishes a relationship between firm-specific investor sentiment and stock price movements around earnings announcements. We find that firm-specific investor sentiment is a key determinant of price adjustment in the context of an earnings surprise....

We examine the role of institutional investors underlying post-earnings-announcement drift (PEAD). Our results show that while institutional investors generally herd on earnings news, such correlated trading among institutions does not eliminate or reduce market underreaction to earnings...

Prior literature suggests that the market underreacts to the positive correlation in a typical firm's seasonal earnings changes, which leads to a post-earnings-announcement drift (PEAD) in prices. We examine the market reaction for a distinct set of firms whose seasonal earnings changes are...

This paper provides new evidence that investor attention explains positive returns around earnings announcements and reconciles the attention explanation with information-based explanations in the literature. I use earnings notifications, which are attention-grabbing announcements of the...
