RSS for COSTNew congressional filings in this symbol, by filing date.

Educated guesstimate only. Filings report ranges, not exact sizes. Share counts use the range midpoint (or 1.5× the floor for “Over $X”) and the closing price on the trade date. Open lots are marked to the latest Yahoo Finance close. Cash dividends and split factors are applied while a reconstructed lot is open. Sales with no matching disclosed buy are treated as closing an unseen lot at the sale price (about $0 P/L on that slice). Bonds and rows without a usable ticker are excluded. This is not actual profit.
