Form 4 (US insider filing)
The US SEC form for reporting insider trades — the EDGAR equivalent of SEDI.
Form 4 is filed via SEC EDGAR within 2 business days of an insider trade on a US-listed issuer. Filers include officers, directors, and 10%+ shareholders. Form 4 captures share count, price, transaction code, and post-trade holdings. The 2-day filing window makes Form 4 a faster signal than SEDI's 5-day window.
