The law
The STOCK Act (Stop Trading on Congressional Knowledge Act, 2012) affirmed that members of Congress are not exempt from insider-trading law and required them to publicly disclose securities transactions. The operative rule: any covered trade over $1,000 must be reported in a Periodic Transaction Report (PTR) within 30 days of the member becoming aware of it — and no later than 45 days after the trade itself.
Where the filings live
House members' disclosures are published by the Clerk of the House; Senators' through the Senate's electronic financial disclosure (eFD) system. Both are free and public — they're the primary sources behind our Follow the Politicians tracker.
How to read a PTR without fooling yourself
Three critical caveats. (1) Amounts are ranges, not exact figures — disclosures use brackets like "$1,001–$15,000" or "$1,000,001–$5,000,000," so headlines claiming a member "bought $5 million" of a stock usually cite the top of a range. (2) Many trades aren't the member's own decision — filings frequently cover a spouse's account, a jointly held account, or a manager-run trust; the owner column matters. The most-tracked portfolios in Congress are largely spousal trading (Nancy Pelosi profile) or family trusts (Ro Khanna profile). (3) Disclosure isn't proof of wrongdoing — a filed PTR is compliance, not a confession; patterns and timing raise questions, but the filing itself is the system working.

Why people watch anyway
Members of Congress sit on committees with market-moving information — defense, health, banking, technology — and studies and journalists have long debated whether congressional portfolios outperform. Public pressure from trackers has fueled recurring reform proposals to ban congressional stock trading outright. Until any such ban passes, the disclosures are public record — and watching them is both civic oversight and market curiosity. Our tracker follows the most active disclosed traders in both parties, with every profile linking to the official filing source.
The enforcement gap
The STOCK Act's standard penalty for a late filing starts at just $200, and late filings are common — several highly tracked members have repeatedly disclosed trades past the deadline. Remember that when timing matters to your analysis: the trade may be up to 45 days old (legally) or older (with a late fee).
FAQ
Do members have to disclose crypto or funds?
Covered financial instruments include stocks, bonds, and other securities over the $1,000 threshold; broad rules also reach many other assets on annual disclosures — the PTR system is transaction-focused.
Can I get alerts?
The filings are public; several trackers (including ours, via The Money Trail) surface notable disclosures as they're filed.
Does a disclosed buy mean the member picked the stock?
Often not — check the owner field (spouse/joint/trust) and whether the account is independently managed.
