We identify a new mechanism of opportunistic insider trading that is associated with attention-driven mispricing. Insiders are more likely to sell their company’s stock after increases in retail attention, and they are more likely to buy after attention decreases. A long-short insider-trading...

This paper shows investors' lottery preference can attenuate price underreaction to extreme good earnings news. Such news reaffirms investors' preference for stocks with strong ex ante lottery-like features, thereby accelerating price adjustments. We find that PEAD attenuates for stocks with...

Theory offers three main determinants of informationally driven trading volume at earnings announcements: pre-announcement difference in private information precision, belief divergence or differential interpretation, and signal strength. In this paper, we empirically test which theoretical...

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...
