What Is the STOCK Act? Everything You Need to Know
The Stop Trading on Congressional Knowledge Act (STOCK Act) was signed into law on April 4, 2012. It explicitly prohibits members of Congress and their staff from using non-public information for personal financial gain and requires regular disclosure of securities transactions.
Key Provisions
- Members must file PTRs within 45 days of a trade
- Applies to House and Senate members and senior staff
- Covers stocks, bonds, commodity futures, and other securities
- Violations can result in fines (though enforcement has been limited)
History & Background
Before the STOCK Act, there was no explicit prohibition on congressional insider trading. A 2004 academic study found that US Senators' personal stock portfolios beat the market by approximately 12% per year. Public pressure, particularly after reports of trades ahead of the 2020 pandemic, led to renewed calls for stricter enforcement.
Current Enforcement
While the law is clear, enforcement has been inconsistent. Late filings are common, and penalties are often minimal ($200 fines). Several proposals have been introduced to strengthen the law, including outright bans on individual stock trading by members of Congress.
