Abstract

There is sufficient evidence in the popular, legal, and financial literatures that informed options trading ahead of scheduled and unexpected corporate events is pervasive. In this review, we piece together the extant evidence on this topic into a cohesive picture, which includes abnormal activity ahead of announcements of earnings, mergers and acquisitions, as well as numerous other corporate events. We also discuss the more limited evidence on informed trading in other derivatives markets, such as credit default swaps. In addition, we characterize the impact and features of illegal insider trading and insider trading networks. We also provide a brief overview of the legal framework in the United States concerning legal and illegal insider trading to emphasize the challenges associated with identifying informed options trading. We end with our suggestions regarding future research opportunities in this broad topic.
