What is insider trading?
Insider trading is the buying or selling of a public company’s stock by people with access to material, non-public information, typically its directors, officers, or shareholders who own more than 10%. When done legally, these trades must be disclosed to the SEC, usually on a Form 4 filed within two business days.
What is an SEC Form 4?
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 company stock: a purchase, sale, option exercise, or gift. It names the insider, their role, the transaction type and size, and the shares they hold afterward.
How do I track insider trades?
alphai reads every SEC Form 4 as it is filed, groups each filing into a single economic event, scores it for relevance, and surfaces it here and on each company’s page. Buys, sells, and 10b5-1 plan sales are separated so you can read real conviction at a glance. Set an alert on any ticker to be notified the moment a new filing lands.
How do I find stocks insiders are buying?
Use this page as an insider buying tracker: every Form 4 open-market purchase (transaction code P) is grouped by filing, scored, and searchable by ticker, so you can see the stocks insiders are buying rather than routinely selling. Watch for cluster buys (several officers or directors buying the same stock within days) and purchases into a price drop, which tend to signal the strongest conviction. Set an alert to catch new insider buying on any ticker as it is filed.
