InsiderTape: SEC Insider Trading Tracker, Without the Noise
Most insider trackers just dump raw SEC filings on you, and the vast majority is meaningless: stock awards, exercised options, tax-related sales, and automatic dividend-reinvestment buys. InsiderTape filters all of that out, leaving only real open-market trades where an insider chose to put their own money in or take it out. Then it goes further, running every trade through signal detection: cluster buys where multiple insiders pile into the same stock, first purchases after years of silence, conviction buys timed just before earnings, and exit warnings when executives head for the door. The result is a clean, ranked view of where the smart money is actually moving, not a firehose of filings.
What You Can Do on InsiderTape
- Screen Form 4 filings - Filter corporate insider trades by ticker, role (CEO, CFO, Director), transaction value, and time period. Spot open-market buys and sells across thousands of U.S. issuers.
- Detect cluster buying signals - Our cluster detection engine surfaces tickers where multiple insiders are buying in a short window, after a decline, with no offsetting sells - a rare, high-conviction pattern.
- Score individual insiders - Every Form 4 insider is scored on actual forward returns: win rate, average 30-day and 90-day returns, consistency, and timing alpha. Find the insiders whose buys have historically preceded upward moves.
- Monitor first-buy signals - Detect insiders making their first open-market purchase after years of inactivity on a stock. One of the rarest and most deliberate signals in Form 4 data.
- Compare stock insider activity - Look up any ticker and see a year of insider buying and selling plotted directly on the price chart, alongside Form 4 trade history for that name.
- Spot exit warnings - Identify tickers where multiple insiders, especially executives, are selling concurrently or selling volume is accelerating.
Data Sources
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. InsiderTape ingests new filings throughout every trading day.
Why Insider Trading Data Matters
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.
Common Questions
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.
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). 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.
