About this page
Stock trades reported by members of Congress under the STOCK Act, with what each stock did afterward.
How to read it
- STOCK Act
- A 2012 law that requires members of Congress to report stock trades by themselves, a spouse or a dependent child within 45 days.
- Periodic Transaction Report (PTR)
- The form those trades are reported on. Amounts are given only as ranges, such as $1,001 to $15,000.
- Owner
- Member, spouse, joint or child, as written on the report.
- What happened next
- How the stock moved after the trade compared with the S&P 500. It measures timing, not the member's profit.
A real example
In 2020 several senators faced questions over stock sales made after private briefings on the coronavirus early that year. Those trades became public through the same STOCK Act reports this page is built from.
Explain it like I'm 13
Lawmakers write the rules for everyone, and some of them also own stocks. The law says they must tell the public when they trade, a bit like a referee who also plays having to show what bets he made. This page shows those notes.

What the stocks did next
For each trade, the change in the stock's price from the week of the trade to the same window later, and the same change minus the S&P 500 (SPY). For sales, a fall afterward means the stock was sold before a drop.

Weekly prices from SEC fails-to-deliver data; the S&P 500 is measured with the SPY ETF. Exact trade prices and amounts are not disclosed, so these are the stocks' moves, not the member's profit. Dividends are not included, and windows with a likely stock split are skipped. A move after a trade does not mean the trade caused it. Past results do not predict future ones.
