When a CEO or director buys their own company's stock on the open market, they must report it on SEC Form 4 within two business days — one of the fastest, cleanest disclosure signals in public markets. We filter the raw feed to real open-market buys and sells (stripping out option exercises and compensation noise), flag abnormal patterns like cluster buying and C-suite purchases, and score every stock's recent insider activity.

SEC Form 4 is the report corporate insiders — officers, directors, and 10%+ owners — must file within two business days of buying or selling their company's stock. Unlike quarterly 13F filings, Form 4 is nearly real-time.
Insiders sell for many reasons — diversification, taxes, a house — but they generally buy on the open market for one reason: they expect the price to rise. That's why our feed emphasizes open-market purchases (transaction code P) and treats sales as much weaker evidence.
When several insiders at the same company buy within a short window, it suggests shared conviction rather than one person's opinion. Cluster buys are one of the abnormal signals we flag automatically above.
“Insiders might sell their shares for any number of reasons, but they buy for only one reason: they think the price will go up.” — Peter Lynch
