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...

By employing the modified net buying pressure as a measure of informed option trading, this study tested whether option trading around quarterly earnings announcements is either directionally motivated and/or volatility motivated. We found evidence that is consistent with the idea that option...
