How it is built. On each annual financial disclosure’s filing date the book is reset to the stocks the report lists, at the midpoints of their value ranges. Between reports, each disclosed purchase buys the midpoint of its range at the trade-date close and each sale sells its midpoint. Options count as their underlying stock at their reported value. Returns are time-weighted on split-adjusted prices without dividends, for SPY as well. ETFs, funds, bonds and private holdings are not modelled, and a former member’s record ends with their last term.

On the filing date of each annual financial disclosure, the book is reset to the stocks it lists, at the midpoint of each value range. Between reports, each purchase buys the midpoint of its disclosed range at the trade-date close and each sale sells its midpoint. Options count as their underlying stock at their reported value.

Their trades took a median 26 days to be disclosed. 18 of 90 trades were filed after the 45 days the STOCK Act allows.
Members of Congress disclose trades as dollar ranges, up to 45 days after the trade and sometimes later. Volumes use the midpoints of those ranges and are estimates; portfolio figures are a model built from the disclosed trades, not the members’ actual accounts. Not investment advice.
