Two Essays On Insider Trading And Option Grants Around The Filing Of Influential Patents, Liu Pan

Doctoral Dissertations

Research documents that insiders, who have access to private information, appear to trade with profits before major corporate events like mergers, bankruptcy, dividend announcements, and future cash flow news (see, e.g., Seyhun, 1990; Seyhun and Bradley, 1997; John and Lang, 1991; Jiang and Zaman, 2010).

Consequently, financial statements are largely deficient in the information they provide regarding the output of R&D activities.
