With a recent poll showing that 76 percent of voters think members of Congress have an “unfair advantage” in stock trades, I argued in my last post that Congress should adopt a broad rule against trading in individual stocks by sitting cogresspersons (and perhaps their spouses, children, and staff). I argued that such a move would go a long way toward restoring the perception that members of Congress are public servants, as opposed to the current perception shared by many voters that they are public parasites. In addition to restoring public confidence in the legislative branch, I argued adopting such a prophylactic against insider trading would also help improve public confidence in the integrity of our securities markets—a goal Congress has touted repeatedly for almost a century.

I have since posted a short paper on SSRN, Time for a Broad Prophylactic against Congressional Insider Trading, that develops these arguments. Part I offers a brief summary of the current state of insider trading laws, with a special focus on their application to Congress. Part II surveys some of the proposed insider trading reform bills under consideration. Part III argues that, given congresspersons’ unique role vis-à-vis securities markets, a broad prophylactic

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
