Our study examines whether behavioural theories can explain post-earnings announcement drift (i.e., earnings momentum) in the Spanish market. In particular, we test models proposed by Daniel, Hirshleifer, and Subrahmanyan (1998), Hong and Stein (1999), and Barberis, Shleifer, and Vishny (1998)....

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...

Post-earnings announcement drift is stronger in firms that release earnings on days when market returns are higher in magnitude. This drift remains robust after controlling for previously documented factors such as Friday releases, the number of simultaneous releases, and price delay measure....

Prior to investing in a firm, fund managers must evaluate it. This tilts funds’ future portfolio positions toward former portfolio investments, as the past awareness of the firm decreases the cost of evaluating it in the future. We find that firms with many former investors experience...

We show that immediate and delayed abnormal returns following earnings announcement surprises differ across market states. Immediate abnormal returns are more sensitive to earnings surprises in down markets, while delayed abnormal returns are less sensitive; underreaction is attenuated in down...

This study finds that firm life stage affects investor behavior around earnings announcements. Introduction and decline stage companies exhibit significantly less positive cumulative abnormal returns (CARs) around positive earnings surprises and more negative CARs around negative earnings...

This paper provides evidence that the 52-week high serves as a psychological barrier, inducing expectational errors and underreaction to news. Two clear predictions emerge and are confirmed in the data. First, nearness to a 52-week high induces expectational errors; evidence from earnings...

This paper investigates market-level and private investor trading patterns and performance around earnings announcements. We document clear evidence for abnormal trading around earnings announcements for both the entire market and households in Germany and observe that private investor...

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...

Prior studies show that investor learning about earnings-based return predictors from academic research erodes return predictability. However, the signaling power of “bottom-line” earnings has declined over time, which complicates assessments of investor learning about profitability signals...
