We examine the stock price reaction to earnings announcements in the five years following seasoned equity offerings (SEOs). On average, post-SEO earnings announcements are met with a significantly negative abnormal stock price reaction. Although this negative reaction accounts for a disproportionately large portion of long-run post-SEO abnormal stock returns, on average, abnormal stock price reactions to post-seo earnings announcements are reliably negative only within the smallest quartile of equity issuers. For small firms, therefore, these findings are broadly consistent with the hypothesis that firms issue equity when the market overestimates the firm's future earnings perfomance.
