For some time now, the insider trading enforcement regime in the United States has been criticized by market participants, scholars, and jurists alike as lacking clarity, theoretical integrity, and a coherent rationale. One problem is that Congress has never enacted a statute that specifically defines “insider trading.” Instead, the current regime has been cobbled together on an ad hoc basis through the common law and administrative proceedings. As the recent Report of the Bharara Task Force on Insider Trading puts it, the absence of an insider trading statute “has left market participants without sufficient guidance on how to comport themselves, prosecutors and regulators with undue challenges in holding wrongful actors accountable, those accused of misconduct with burdens in defending themselves, and the public with reason to question the fairness and integrity of our securities markets.”

Congress appears to be responding, and a number of bills that would define insider trading and otherwise reform the enforcement regime are receiving bipartisan support. But it would be a mistake to pass new legislation without first taking the time to get clear on the economic and ethical reasons for regulating insider trading. This is particularly true in light of the fact that the general

In 2011, Peter Schweizer published a book, Throw Them All Out, in which he exposed some questionable means by which (according to one study) politicians manage to increase their personal wealth 50% faster than the average American.

According to Schweizer, trading on material nonpublic information appears to be a popular method among congresspersons for achieving outsized returns on their investments. He cites one study finding:

  • The average American investor underperforms the market.
  • The average corporate insider, trading his own company’s stock, beats the market by 7% a year.
  • The average senator beats the market by 12% a year.

Schweitzer’s book was followed by a feature story on the CBS News show, 60 Minutes, highlighting some dubious stock trades by leaders of both political parties. These stories got the public’s attention and spurred Congress to act—adopting the Stop Trading on Congressional Knowledge (STOCK) Act in April of 2012.

The STOCK Act made explicit what many already understood as implicit—that congressional trading based on material nonpublic information acquired by virtue of their position as a public servant was a breach of their fiduciary duties and would therefore violate Section 10b of the Securities Exchange Act of 1934. The Act

As Congress and the SEC continue to contemplate reforms to the U.S. insider-trading enforcement regime, I suggested in my last post that it is important for us all to explore our intuitions about what we think insider trading is, why it is wrong, who is harmed by it, and the nature and extent of the harm. If we are going to rethink how we impose criminal and civil penalties for insider trading, we should have some confidence that the proscribed conduct is wrongful and why. One way to do this is to place ourselves in the shoes of traders and ask, “What would I do?” or “What do I think about that?” To this end, I have developed some scenarios designed to test our attitudes regarding trading scenarios that distinguish the four historical insider trading regimes (laissez faire, fiduciary-fraud, equal access, and parity of information).

In the last post, I offered a scenario that would result in liability under a parity-of-information regime, but not under the other three. Those of you who were not convinced that the trading in that scenario was wrongful may favor one of the less restrictive models.

In this post, I offer the following scenario to
