Disclosure law and filings

STOCK Act: The Stop Trading on Congressional Knowledge Act of 2012 (Public Law 112-105). It affirms that members of Congress and their staff are covered by insider trading law and requires them to publicly report securities transactions over $1,000 within 30 days of being notified of the trade and no later than 45 days after the transaction. Read more →
Periodic Transaction Report (PTR): The filing a member of Congress submits to report an individual purchase, sale or exchange of a security worth more than $1,000. PTRs are the raw source of every congressional trade shown on tracking sites.
Annual Financial Disclosure Report: The yearly statement of assets, income, liabilities, positions and transactions that members file by May 15. It shows holdings in value bands but not the precise timing of each trade, which is why PTRs matter more to investors.
45-day rule: Shorthand for the STOCK Act deadline: a trade must be reported no later than 45 days after it happens. In practice, a stock a member bought on the 1st of the month can legally stay hidden until the middle of the following month.
$1,000 reporting threshold: Transactions of $1,000 or less do not have to be reported on a PTR. Small recurring purchases inside a retirement plan can therefore be invisible to trackers.
Transaction date: The date the trade was executed by the broker. This is the date that matters when judging whether a member traded ahead of news.
Notification date: The date the member says they learned of the trade, for example when a broker statement arrived. The 30-day filing clock starts here, subject to the 45-day outer limit.
Filing date (disclosure date): The date the PTR was submitted and became public. Trackers usually display both the transaction date and the filing date because the gap between them is the disclosure lag.
Disclosure lag: The time between a trade and its public disclosure. Legally up to 45 days, but late filings push it longer. Any strategy that copies congressional trades has to account for it.
Amount range: Disclosures report the size of a trade as a band rather than an exact figure: $1,001–$15,000, $15,001–$50,000, $50,001–$100,000, $100,001–$250,000, $250,001–$500,000, $500,001–$1,000,000, $1,000,001–$5,000,000, $5,000,001–$25,000,000, $25,000,001–$50,000,000 and over $50,000,000.
Late filing fee: The standard penalty for a late PTR is $200, and the ethics committees can waive it. Critics point to this fee as the main reason STOCK Act compliance is inconsistent.
Owner code: A field on House PTRs showing whose account traded: SP for spouse, DC for dependent child, JT for a joint account, and blank when the member traded personally. Spousal trades count toward the member's disclosure duty.
Asset type code: Two-letter codes on House filings that describe the security: ST for stocks (including ADRs), OP for options, MF for mutual funds, EF for exchange-traded funds, GS for government securities, CS for corporate bonds and notes, and CT for cryptocurrency.
Exchange transaction: A trade type where one asset is swapped for another rather than bought or sold for cash, for example in a merger or fund conversion. Trackers often list it alongside purchases and sales.
Capital gains over $200 flag: A checkbox on a PTR indicating that a sale produced more than $200 in capital gains. It is a useful hint that a sale was a profit-taking event rather than a loss harvest.
Amended report: A corrected refiling of a disclosure. Amendments can change the ticker, date, amount band or transaction type, so trackers that ingest filings daily may revise older records.
Qualified blind trust: An arrangement in which an independent trustee manages a member's assets without telling them what is held or traded. Trades inside an approved blind trust are not reported individually, which is why some members show no trading activity.
Excepted investment fund (widely held fund): A publicly traded, widely held mutual fund or ETF whose holdings the member does not control. Purchases and sales of these funds are exempt from PTRs and only appear on the annual report.
Senate eFD: The Senate's Electronic Financial Disclosure system at efdsearch.senate.gov, the official source for senators' PTRs and annual reports.
House Clerk financial disclosure database: The Office of the Clerk's database at disclosures-clerk.house.gov, the official source for representatives' PTRs and annual reports.
Ethics committees: The House Committee on Ethics and the Senate Select Committee on Ethics administer the disclosure rules, review filings and decide whether to assess or waive late fees.

Insider trading and corporate filings

Insider trading (Rule 10b-5): Buying or selling a security on the basis of material non-public information in breach of a duty of trust. The STOCK Act spells out that members of Congress owe such a duty to the public and to Congress. Read more →
Material non-public information (MNPI): Information a reasonable investor would consider important that has not been released to the public, such as the contents of a classified briefing or the outcome of a committee negotiation.
SEC Form 4: The form corporate officers, directors and 10% owners file with the SEC within two business days of a change in their holdings. It is the corporate counterpart of a congressional PTR. Read more →
10% owner: Anyone who beneficially owns more than 10% of a class of a company's equity. They are treated as statutory insiders and must report their trades on Form 4.
Insider buying signal: Open-market purchases by executives or directors using their own money. Analysts weight these more heavily than insider sales, which are often driven by diversification, taxes or option expirations.
Committee assignment: The congressional committees a member sits on. Assignments matter to investors because committee work exposes members to non-public information about the industries they oversee. Read more →

Lobbying and government spending

Lobbying Disclosure Act (LDA): The 1995 federal law that requires lobbying firms and in-house lobbyists to register and file quarterly activity reports with the Secretary of the Senate and the Clerk of the House.
LD-2 report: The quarterly lobbying activity report filed within 20 days after each quarter ends. It lists the client, the registrant's income or expenses, the issues lobbied and the agencies contacted. Read more →
Registrant and client: The registrant is the lobbying firm or organization that files the report; the client is the company or group paying for the lobbying. A public company can appear as either.
Issue code: A standard code on LDA reports that classifies what was lobbied, such as TAX (taxation), HCR (health issues) or DEF (defense). Filtering by issue code links lobbying spend to specific legislation.
USASpending.gov: The official open-data portal for U.S. federal spending. It publishes contract awards, grants and loans by agency, recipient and industry, and is the source for TraderCongress's federal spending data.
Contract award and obligation: An award is the government's agreement to buy from a vendor; an obligation is money legally committed under that award. Investors watch new awards to publicly traded contractors as revenue catalysts. Read more →
NAICS code: The North American Industry Classification System code attached to federal awards. It identifies the industry of the work performed, which makes it possible to total government spending by sector.

Market structure

Dark pool: A private alternative trading system where orders are not displayed before execution. Trades are reported to the consolidated tape afterwards, so daily dark pool volume is public even though the order book is not. Read more →
Off-exchange volume: Shares traded away from lit exchanges, including dark pools and broker internalizers, and reported through FINRA trade reporting facilities. A rising off-exchange share of a stock's volume can signal institutional positioning.
Short volume ratio: The share of a day's reported volume that was sold short, calculated from FINRA's daily short sale volume files. It is a sentiment gauge, not a measure of total short interest.

Strategies and jargon

Pelosi effect: The popular name for the idea that copying trades disclosed by members of Congress, most famously the trades reported on Rep. Nancy Pelosi's filings, produces market-beating returns. Academic evidence is mixed and depends heavily on the period studied. Read more →
Congressional trading ETFs: Exchange-traded funds that build portfolios from congressional disclosures, such as NANC (Democratic members' trades) and KRUZ (Republican members' trades). They offer passive exposure but inherit the full disclosure lag. Read more →
Copy trading (congressional): Mirroring disclosed congressional trades in your own account after they are filed. Because of the disclosure lag, copiers are usually 2 to 6 weeks behind the original trade. Read more →
Conviction trade: A large purchase, typically $50,001 or more, of a single stock that stands out from a member's usual activity. Trackers flag these because size is one of the few signals of intent a disclosure provides.
Bipartisan clustering: Several members from both parties buying the same ticker within a short window. It is treated as a stronger signal than a single trade because it suggests shared information rather than one person's portfolio decision.
Watchlist: A saved list of tickers or members you follow inside a tracker. On TraderCongress, watchlists drive the activity feed and can be paired with alert rules.
Alert rule: Saved criteria such as a ticker, a member, a transaction type and a minimum amount that trigger an email or in-app notification when a matching disclosure is filed. Read more →

Frequently Asked Questions

What is a Periodic Transaction Report (PTR)?

A Periodic Transaction Report is the filing a member of Congress submits to disclose an individual purchase, sale or exchange of a security worth more than $1,000. It shows the ticker, transaction date, filing date, transaction type, whose account traded and an amount range, and it is the raw source of every congressional trade shown on tracking sites.

What does the 45-day rule mean for congressional stock trades?

The STOCK Act requires a trade to be reported within 30 days of the member learning of it and no later than 45 days after the transaction. In practice, a trade can stay hidden for up to a month and a half, and late filings extend that further. Anyone copying congressional trades is therefore acting on information that is typically two to six weeks old.

What do the amount ranges on congressional disclosures mean?

Disclosures report the size of each trade as a band rather than an exact figure: $1,001–$15,000, $15,001–$50,000, $50,001–$100,000, $100,001–$250,000, $250,001–$500,000, $500,001–$1,000,000, $1,000,001–$5,000,000, $5,000,001–$25,000,000, $25,000,001–$50,000,000 and over $50,000,000. A trade shown as $1,001–$15,000 could be either end of that range.

What is the difference between a PTR and an SEC Form 4?

A PTR is filed by a member of Congress under the STOCK Act within 45 days of a trade in any company. A Form 4 is filed with the SEC by a corporate officer, director or 10% owner within two business days of trading their own company's stock. Both are public, but Form 4 shows exact share counts and prices while a PTR shows only an amount range.
