In this project, we propose a framework for identifying option trades that maximize expected returns under liquidity听constraints for investors with private but noisy information. Our primary objective is to improve the detection of听illegal insider trading by understanding how insiders can benefit from trading differentially depending on the type听and quality of their private information, i.e., the precision of its signal. We first implement our approach numerically听for a wide range of option trading strategies and various private signals and then apply it empirically to document听suspicious activity in option markets prior to large changes in stock prices associated with different types of听corporate news events. In most instances, an investor with a private signal about an upcoming change in the price of听the underlying stock maximizes his profits by acquiring options trading near the money, or by pursuing trading听strategies involving more than one security. Differences in trading as a function of signal and parameter uncertainty听improve our understanding of how informed investors trade in the options market.
