Frequently Asked Questions
What is a Form 4?
SEC Form 4 is filed by corporate insiders (officers, directors, 10%+ owners) within 2 business days of buying or selling company stock.
Why focus on open-market transactions?
Open-market buys (code P) and sells (code S) are voluntary. Option exercises and gifts have different signals and are excluded from headlines.
Is insider buying a good signal?
Historically, clustered insider buying has been a modestly bullish signal. Insiders know their company best. But one buy is not a recommendation; context matters.
How often does this update?
We poll SEC EDGAR every 30 minutes for new Form 4 filings. The SEC publishes throughout the trading day.
Is there per-ticker data?
Yes. Click any ticker to see its full insider transaction history. Also available via the API.
