Trades from House and Senate periodic transaction reports filed Jan 1, 2012 to Oct 30, 2026. Holdings are estimated from range midpoints: purchases add, partial sales subtract and full sales close the position, marked to the latest close where prices exist; matured bonds, expired options and delisted stocks drop out. They are not reported balances. Returns are time-weighted returns of the estimated stock and ETF holdings, with each trade taking effect at the close on its filing date (the member's own trade-date result is shown beneath): each window is split at the member's trade dates and the holdings' performance over each stretch, from daily closes, is chained, so the timing and size of purchases and sales do not dilute or inflate the result. Party, district and committee seats come from the congress-legislators dataset.
