Corporate insiders — officers, directors, and 10% shareholders — are required by the SEC to disclose purchases and sales of their own company's stock on Form 4 within two business days. This public filing data is what we track.
Form 4 is the Statement of Changes in Beneficial Ownership filed with the SEC whenever an insider transacts in their company's securities. Each trade you see on this site comes from a real Form 4 filing.
When three or more different insiders at the same company buy stock within a short window (typically 30 days), that's a cluster buy. Historically, cluster-buying has been a stronger signal than any single insider's trade.
We re-crawl SEC EDGAR every few minutes and typically surface new filings within 5–15 minutes of when the SEC publishes them.
