Insider and congress trading, by company

Corporate insiders file Form 4 with the SEC within two business days of a trade. Members of Congress disclose under the STOCK Act within 45 days. These are the 1603 companies with a page here: every company we hold filing history for, plus every current S&P 500 and Nasdaq 100 member. Each page shows who traded, how much, and how long the filing took to reach the public.

503 of the 503 S&P 500 and 102 of the 102 Nasdaq 100 companies have a page here, whatever their filing history, membership as of Sep 10, 2026.
