Congress trading

Every stock trade disclosed by Congress

Every line of every STOCK Act report we hold, from House Clerk and Senate recordsEvery STOCK Act trade since 2014. Newest filing first, as of Nov 4, 2026; narrow the record by member, party, chamber, ticker, account or size, and every name and ticker opens its own page.

320 MRK trades filed since 2014

Across 220 reports by 50 members · newest filing first · every Congress trade in the stock is on Merck's page

Sizes are the dollar ranges members report, never an exact amount. How to read the cards.

Since the trade: the stock's move from its estimated entry price (a purchase) or estimated exit price (a sale) to its current price, the latest close we hold. Not the member's result.

How to read the cards

  • One card: one report a member filed with the House Clerk or the Secretary of the Senate, newest filing first, its trades in date order. A trade the report lists twice, on the same day in the same range for two accounts, shows once here.
  • Size: the dollar range on the report, never an exact figure. A value that is not one of the STOCK Act's ranges prints as listed, and "Not captured" means the range is missing from our data.
  • Traded and disclosed: the trade date, then the days until the member disclosed it. The STOCK Act allows 45 days. The date filter counts from the filing date, not the trade date.
  • Since the trade: each priced line shows the estimated entry or exit price and the current price it is worked out from. Estimated prices are the stock's closing price on the trade date. A disclosure gives a value band, not the price paid. An option line reads n/a, because an option's premium is never disclosed; so does any other line that is not a stock, and a stock line whose closing prices we do not hold or whose prices failed our checks. Not investment advice.
  • Filed late: only on reports we checked against the House Clerk's copy, listed on the late filings page. A checked card links the original.
  • Long reports: 20 reports to a page. A report longer than 60 trades is shortened here, and so are the reports after a page passes 250 trades; the member's own page has every trade.
