A little tour of how it works
Pip · your what-if buddyMore than Congress
49 datasets · 1.6M recordsCongressional trading is where this started, and it is now about 17% of what is here. The rest is the public record on the same companies — what they spend lobbying, what agencies pay them, what they file at the patent office, what OSHA found at their sites — and the figures that move whole markets.
Small steps. A clearer picture.
A peek behind the numbersPick your budget
Your total is divided evenly across eligible purchases in the selected filing period. Money waits in cash until each entry.
Follow the public filing
Buy at the first available close on or after publication. You enter when the trade becomes public, which can be weeks after the member traded.

Assumptions & data coverage
This is a retrospective illustration using the filings currently stored here, not a forecast or a complete history of a member’s portfolio. Equal allocation uses the number of eligible purchases known at the end of the chosen period. It does not reproduce a strategy you could size in advance.
Fractional shares are allowed. A filing-day close is an assumption because publication times are not available. Options, unknown publication dates, non-positive prices, and price histories with gaps longer than 10 days are excluded. Non-trading days use the last known close.
Sales, dividends, fees, taxes, slippage, and cash interest are not modeled. These omissions can change returns in either direction. Prices are historical daily closes, not live quotes.
