The STOCK Act (2012) banned insider trading by Members of Congress and required disclosure of trades. But the disclosure regime is widely flagged as weak: late filings rarely produce meaningful penalties, trade reporting lags by 30-45 days, and several Members have outperformed market benchmarks at suspicious rates.
Reform proposals include the Pelosi-Tuberville range of "ETRUST" / "PELOSI" / "Restore Trust" bills that would require Members to either divest individual holdings, place them in a qualified blind trust, or limit trades to broad index funds.
Defenders argue Members should not be uniquely barred from ordinary financial planning. Critics argue the appearance and reality of trading on inside information corrodes public trust.
