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...

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....

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)....

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...

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...

This study examines the effect of option volume relative to stock volume (O/S) on market response to earnings surprises. The market reaction per unit of earnings surprise is lower for firms that have high O/S prior to earnings announcement than for firms with low O/S prior to earnings...

This paper investigates the robustness of post-earnings-announcement-drift (PEAD) on a price signal perspective, unlike the traditional literature that focuses on fundamental signal. The studied period is 2003-2015, for four main US indices. The results suggest that some economic agents are too...

This paper examines the association between insider trading before an earnings announcement and the magnitude of the post-earnings announcement drift (PEAD). Consistent with insiders' private information being incorporated into prices through their trading, we find PEAD is significantly lower...

This paper examines the association between insider trading prior to quarterly earnings announcements and the magnitude of the post-earnings announcement drift (PEAD). We conjecture and find that insider trades reflect insiders’ private information about the persistence of earnings news. Thus,...

We examine the effect of options trading volume on the stock price response to earnings announcements over the period 1996–2007. Contrary to prior studies, we find no significant difference in the immediate stock price response to earnings information announcements between firms with listed...
