About Form 4
Corporate insiders — officers, directors and 10%+ owners — must report their trades to the SEC on Form 4 within two business days. We group each filing's transactions into one economic event (a laddered 10b5-1 sale is one event, not 25 rows), flag pre-arranged plans and late filings, and link every event to its AI-scored article in the $GKOS feed.
