Fighting insider trading is clearly at the top of law enforcement’s agenda. In May 2011, Raj Rajaratnam, the former head of the Galleon Group hedge fund, received an eleven-year prison sentence for insider trading, the longest ever imposed. More recently, in July 2013, SAC Capital Advisors, a $15 billion hedge fund, was slapped with a criminal complaint that threatens the fund’s existence, even after having agreed to pay a $616 million civil penalty, the largest-ever settlement of an insider trading action. Yet, despite the high enforcement priority and the high stakes involved, a satisfying theory of insider trading law has yet to emerge. And this is not for want of trying. As Larry Mitchell remarked as early as 1988, “Many forests have been destroyed in the quest to understand and explain the law of insider trading.”
In my forthcoming article, Insider Trading as Private Corruption, to be published next year in the UCLA Law Review, I make the case that insider trading is best understood as a form of private corruption. I begin by arguing that we need a theory of insider trading law that not only makes sense of the law that has developed but also guides the law forward. In my view, such a theory must do two things.
