A Form 4 is the filing a corporate insider submits to the U.S. Securities and Exchange Commission to report a change in their ownership of a company’s stock: a purchase, sale, option exercise, or gift. Directors, officers, and shareholders who own more than 10% must file one within two business days of the transaction. It names the insider, their role, the transaction type and size, the price, and the shares they hold afterward.
Each line on a Form 4 carries a transaction code. The two that matter most are P (an open-market purchase) and S (an open-market sale), because they represent real conviction. A is a grant or award, M is an option or derivative exercise, F is shares withheld to cover taxes, and G is a gift. AlphAI groups a filing’s non-derivative P/S trades into a single economic event so a 25-tranche 10b5-1 sale reads as one sale, not 25 rows.
The SEC requires insiders to file a Form 4 within two business days of the transaction. AlphAI tails SEC EDGAR continuously and turns each new filing into a scored feed row within minutes of it posting, so you see it about as fast as the disclosure exists.
The primary source is the SEC’s EDGAR system. AlphAI reads every Form 4 as it is filed, decodes the transaction codes, groups each filing into one event, scores it for relevance, and surfaces it here, on the Insider Trading Tracker, and on each company’s page. You can set a free email alert on any ticker, and the same data is available via the API and MCP server.
