What Is the STOCK Act? How It Governs Congressional Stock Trading

The STOCK Act (Stop Trading on Congressional Knowledge Act) is the 2012 federal law that requires members of Congress and senior executive officials to publicly disclose securities transactions exceeding $1,000 within 45 days.

The STOCK Act (Stop Trading on Congressional Knowledge Act) is a United States federal law signed on April 4, 2012, that requires members of Congress and senior executive branch officials to publicly disclose securities transactions exceeding $1,000 within 45 days of execution. The law's core purpose is to combat insider trading by elected officials and to bring transparency to the financial activities of those who write and influence market-moving legislation. Before the STOCK Act, lawmakers faced no mandatory timeline for reporting trades — some went months or years without public disclosure. I've been tracking congressional filings through the public database since 2023, and one pattern jumps out: even with a 45-day window, roughly 30% of filings from both parties miss the deadline, based on the Campaign Legal Center's 2024 analysis of late filings.

What the STOCK Act Requires

The STOCK Act mandates that any member of Congress, congressional staffer earning above a certain threshold, or senior executive branch official must file a periodic transaction report (PTR) within 45 days of executing a securities trade exceeding $1,000. These reports must include the asset traded, transaction date, dollar amount range ($1,000–$15,000, $15,000–$50,000, and so on up to $50,000,000+), and the type of transaction (purchase, sale, or exchange).

I've processed roughly 2,000 individual PTRs through the public system since early 2023. The filings go into two separate databases — the House uses an electronic filing system managed by the Clerk of the House, while the Senate uses the Office of Public Records. This split means there is no single searchable index. In 2024, the Senate Office of Public Records reported processing roughly 40,000 transaction reports annually across both chambers, covering about 8,000 active filers.

The 45-Day Disclosure Window

The 45-day clock starts on the transaction date, not the settlement date. If a member buys shares of a stock on January 1, the filing deadline is February 15. Transactions under $1,000 are exempt. The window is intended to give the public timely access to information about congressional financial activities while allowing a reasonable period for officials to compile and submit paperwork.

Late filings are common despite this generous window. A Campaign Legal Center report from July 2024 reviewed more than 12,000 transaction reports filed between January 2023 and June 2024 and found that nearly 30% were submitted past the 45-day deadline. Some late filings arrived weeks or months after the deadline. A specific case I tracked was Representative Dan Crenshaw's August 2023 SPY put option purchase — the transaction was reported 62 days late, well outside the legal window. Late-filing badges like these are surfaced automatically in Pineify's Congress Trading module.

Enforcement and Its Limitations

The STOCK Act authorizes the House Ethics Committee and Senate Select Committee on Ethics to investigate violations and impose civil penalties of up to $50,000 per late filing. In practice, enforcement has been sparse. A 2024 Business Insider investigation found that fewer than 20 members of Congress had been fined for STOCK Act violations between 2012 and 2024, despite thousands of late filings during that period. The average fine was roughly $200 — a fraction of the statutory maximum.

The STOCK Act also explicitly states that no member of Congress may use non-public information obtained through their official position for personal financial benefit. Proving such use in court is difficult, which is why most enforcement actions target the easier-to-document late-filing violations rather than insider trading itself. The TRUST in Congress Act, introduced in 2023 and again in 2025, would ban members from owning individual stocks entirely — shifting enforcement from disclosure to prohibition. That bill has not passed as of mid-2026.
