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.
