Abstract
I examine the relationship between common institutional ownership (CIO) and opportunistic insider trading. This relationship is important given the tremendous increase in CIO over the past 20 years and the detrimental effect of opportunistic insider trading on shareholder value. I hypothesize that CIO is negatively associated with opportunistic insider trading. Consistent with this view, I find that the presence of CIO significantly reduces opportunistic insider trading value, volume, and insider frequency. Additionally, I find that CIO by active institutions has a stronger negative association with opportunistic insider trading than CIO by passive institutions. Specifically, my results show that the presence of CIO from active institutions significantly reduces the dollar value, trading volume, and frequency of opportunistic insider trading. Furthermore, I find that this inverse relation is more evident for opportunistic insider sales than opportunistic insider purchases. Overall, my findings suggest that CIO plays an important role in insider trading decisions by enhancing monitoring effectiveness and efficiency, and by reducing commonly owned firms’ information asymmetry.
