Where this data comes from. Insider trades, fund holdings, activist stakes and company results come from public SEC EDGAR filings (Forms 4, 13F, 13D/13G, 10-Q and 8-K). Congress trades come from the STOCK Act reports members file with the House Clerk and the Senate. Daily closing prices come from post-no-preference/stocks on DoltHub, a community-run database shared under CC BY-SA 4.0; the prices we show stay under that license. They are each day's close, not live or official exchange prices.
