The STOCK Act, disclosure timelines, and using congressional trading data in research.
Yes, it is legal to use publicly filed congressional trading disclosures in your investment research. These filings are public records, available to anyone.
What is illegal is for members of Congress themselves to trade on material non-public information (MNPI) gained through their official duties — though enforcement of this prohibition has been limited.
The Stop Trading on Congressional Knowledge (STOCK) Act became law in April 2012. Key provisions:
The most significant limitation: Congress members have up to 45 days to disclose trades. By the time the public sees the filing, the trade may be 6+ weeks old. Any short-term signal value is diminished by this delay.
However, the data remains valuable for identifying:
Academic studies have examined whether congressional portfolios outperform market benchmarks. Key findings across multiple research papers:
The most significant signals tend to come from members on committees with direct oversight:
| Source | Coverage | Delay |
|---|---|---|
| House Financial Disclosures (official) | All House members | Up to 45 days after trade |
| Senate Financial Disclosures (official) | All Senate members | Up to 45 days after trade |
| Fin45 Congressional Trades Tracker | All members (aggregated) | Parsed within hours of filing |
The Fin45 AI agent monitors both House and Senate financial disclosures as one of 11 signal categories. Congressional data is scored based on:
Congressional signals alone don't trigger trades — they must reach ≥ 0.75 conviction and have multi-source confirmation before the agent considers a position.

Yes. Congressional financial disclosures are public records filed under the STOCK Act. Anyone can access and use this data for investment research. What is illegal is for Congress members to trade on non-public information — using their filed disclosures after publication is entirely legal.
The Stop Trading on Congressional Knowledge Act (2012) prohibits members of Congress from insider trading and requires disclosure of stock transactions over $1,000 within 45 days. Filings are public records available on House and Senate websites.
Members of Congress must disclose trades within 45 days under the STOCK Act. Many file later, with the maximum penalty being $200 for late disclosure. This delay significantly reduces short-term signal value for public followers.
Multiple academic studies have found that congressional portfolios outperform market benchmarks, particularly among members with committee oversight of specific industries. Whether this constitutes illegal activity or informed research remains debated and rarely prosecuted.
