Trading outside the main session occurs between 4:00PM-8:00PM and 4:00AM-9:30AM and is typically dominated by institutional investors, as retail investors are discouraged to trade in the extended trading hours. This study examines whether trading in the extended hours is predictive of future...

This paper investigates earnings revisions that occur between preliminary earnings announcements and the immediate subsequent SEC filings. On average, the absolute value of the revision is 2.9% of the market value of equity where earnings were revised by more than $100,000. We find that earnings...

This study provides evidence that a significant percentage of analyst forecast revisions are issued promptly after a broad set of corporate public disclosures and that investors perceive these prompt revisions as more valuable than non-prompt revisions. These results hold for all revisions,...

Recent evidence shows that option volatility skews and volatility spreads between call and put options predict equity returns. This study investigates whether such predictive ability is driven by option traders' information advantage. We examine the predictive ability of volatility skews and...

We examine how insider trading affects market responses to subsequent analyst forecast revisions in a global setting. We find stronger market responses to analyst forecast revisions subsequent to the insider trading than to other revisions. This stronger response is mainly driven by analyst...

The Post-Earnings Announcement Drift (PEAD) anomaly refers to the tendency of stock prices to continue drifting in the same direction as earnings surprises well through the subsequent earnings announcements; ignoring the autocorrelations in extreme earnings surprises across adjacent quarters....

This paper investigates the relationship among trading volume around earnings announcements, earnings forecast errors, and subsequent returns. Prior research finds a positive relation between earnings announcement period trading volume and subsequent returns (the high-volume return premium) and...

Consistent with prior studies, this study shows that extremely negative and extremely positive earnings surprises in the fourth quarter have lower levels of persistence than those in the first through third fiscal quarters. Furthermore, extremely negative earnings surprises in the fourth fiscal...

This study explores an additional factor that is associated with differential levels of the post-earnings-announcement drift (henceforth drift) - the contemporaneous surprise in revenues. Consistent with prior evidence about greater persistence of revenues and greater noise caused by...
