InsiderTape tracks every SEC Form 4 filing and STOCK Act disclosure in real time, giving retail investors the same visibility into insider buying and selling that professional analysts have relied on for decades. See exactly what corporate executives, directors, and members of the U.S. Congress are buying and selling — the moment they file — across every U.S.-listed stock.
Corporate insider trading data is pulled directly from SEC EDGAR Form 4 filings, which Section 16 officers (corporate insiders owning more than 10% of a class of stock, plus directors and executive officers) are required to file within two business days of any transaction in their company's securities. Congressional stock trading data comes from STOCK Act disclosures, which require members of the U.S. House of Representatives and U.S. Senate to publicly disclose any stock, bond, or commodity transaction over $1,000 within 45 days. InsiderTape ingests new filings throughout every trading day.
Academic research has repeatedly found that open-market insider buying — particularly cluster buying by multiple executives at the same company within a short window — has historically correlated with above-average forward returns. Insiders are, by definition, the people with the deepest knowledge of their company's operations, pipeline, and prospects. When they put their own money at risk buying their own stock on the open market, it is one of the most credible signals available in public markets. InsiderTape exists to surface those signals instantly, rank them by quality, and put them in front of retail investors the moment they file — the same way hedge funds and institutional desks have been tracking this data for years.
What is SEC Form 4? SEC Form 4 is the filing corporate insiders are required to submit within two business days of any transaction in their company's equity securities. It reports the date, transaction type (purchase, sale, option exercise), number of shares, price per share, and total value of the trade, along with the insider's position at the company.
What is the STOCK Act? The Stop Trading on Congressional Knowledge Act of 2012 requires members of the U.S. House and Senate, along with senior congressional staff, to publicly disclose any stock, bond, or commodity transaction over $1,000 within 45 days. These disclosures are published as periodic transaction reports (PTRs).
Is insider trading legal? The insider trades tracked on InsiderTape are all legally disclosed transactions filed under Section 16 of the Securities Exchange Act of 1934 (corporate insiders) or the STOCK Act (congressional members). This is the legal, publicly-reported insider activity — not the illegal material non-public information kind.
How often is InsiderTape updated? New SEC Form 4 filings are ingested throughout the trading day as they're published to EDGAR. Congressional STOCK Act disclosures are ingested daily.
