What is a SEC Form 4 filing?

SEC Form 4 is a filing that corporate insiders (officers, directors, and 10%+ shareholders) must submit within two business days of buying or selling their company's stock. It is the primary source of insider trading data in the United States.

What types of insider transactions are tracked?

This database tracks open-market purchases (buys) and sales (sells) of non-derivative securities. These are the most meaningful insider transactions because they represent voluntary investment decisions by people with deep knowledge of the company.

About This Data

Every transaction in this database comes from SEC Form 4 filings, which corporate insiders are legally required to file within two business days of a trade. Insiders include officers (CEO, CFO, etc.), directors, and shareholders who own more than 10% of a company's stock.

Use the filters above to narrow your search. Filter by transaction type to see only buys or sells, by sector and industry to focus on a specific area of the market, or set a minimum transaction value to find the largest trades. The insider type filter lets you isolate C-suite executives, directors, or 10% owners.
