Politicians' portfolios

Members of the US Congress must disclose every transaction over $1,000 within 45 days (STOCK Act, 2012). House of Representatives disclosures are read directly at the source (Clerk of the House). The Senate and executive branch services refuse automated access from Europe: senators, the President and cabinet members come from a public mirror (kadoa-org open source project, MIT license) that copies the official disclosures every day. These rows are marked “mirror”, each one links to the official document, and they disappear on their own if the mirror stops being updated.

Prices: Yahoo Finance, excluding dividends. Parties and committees: congress-legislators (public domain). Stocks and ETFs only.

A disclosure gives an amount range, never a number of shares. A position stays in the Long tab as long as no full sale has been disclosed. A partial sale leaves it in Long and marks it “trimmed”. A full sale moves it to the Short tab for six months. Short here means “sold”, not a short sale: politicians do not disclose short positions.

The executive branch form (278-T) does not say whether a sale is full or partial: every sale by the President or a cabinet member goes to Short marked “size not specified”.

Each disclosed account (trust, retirement account…) is tracked separately: a full sale in one does not close the same holding in another. Positions are rebuilt from the disclosures of the last three calendar years: a stock bought before and never sold since does not appear. Transactions by a spouse, a child or a joint account are flagged as such.

Politician perf. starts from the close on the transaction date. Perf. since disclosure starts from the first close after the disclosure was published: the best a reader could get. Both are weighted by the midpoint of the disclosed range and compared with the S&P 500 (SPY) over the same dates. The gap between the two measures what the disclosure delay cost the reader.

For a sale, realized perf. compares the price on the sale date with the entry price (when the purchases are known), and “since the sale” shows what the stock did afterwards.

The delay is the number of days between the transaction and its disclosure. Beyond 45 days it is flagged, without presuming a violation: a politician may learn of a spouse's transaction later. In a company profile, a committee's name appears next to a holder when they sit on it and it has jurisdiction over the sector, based on a table we built ourselves: a correlation worth examining, not an accusation.

The key issues are picked from the risk factors the company itself reports to the SEC and shown in their original wording (the French version is translated by a language model installed on the server and checked mechanically: no figure or name missing from the original text). Federal contracts: USAspending. Executives: SEC Form 4 filings. Nothing is written freely by an AI.

Two ETFs listed in New York replicate politicians' disclosures: NANC for Democrats and GOP for Republicans (fees of about 0.7% a year). Apps such as Autopilot place the orders for their subscribers. None has access to transactions before they are published: they read the same disclosures as this page, with the same delay.

Recent studies find no average outperformance by politicians since the STOCK Act, and even less for those who copy them after disclosure (Belmont, Sacerdote, Sehgal and Van Hoek, 2022). Some observe an edge among House leaders (Wei and Zhou, 2025).

These disclosures are public and US law prohibits their commercial use (5 U.S.C. §13107): this page is free and will stay free. Disclosures filed on paper (often handwritten scans) are not read: they are listed in each politician's profile, with a link to the document. Nothing here constitutes investment advice.
