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...

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...

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 contributes to the debate on the consequences of increased disclosure regulation by investigating the effects of expedited reporting requirements of Form 4 filings, mandated by the Sarbanes-Oxley Act (SOX), on the market response to earnings announcements. We first confirm that SOX...

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...

Motivated by investor disagreement and corporate disclosure literatures, we examine how stock price shocks affect future stock returns. We find that both large short-term price drops and hikes are followed by negative abnormal returns over the subsequent year, consistent with the conjecture that...

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...

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....

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,...

This paper shows that in asset pricing the information environment gives rise to a systematic risk factor when the informativeness of future news events varies with their content (i.e., bad news and good news are not equally informative). The paper further shows that in such cases (cross) serial...
