Insider Trading Tracker

Insider buys, sells, and 10b5-1 plans: every SEC Form 4, grouped into a single event, scored, and searchable by ticker.

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.

Do insider purchases predict stock returns?

The evidence points to a small short-horizon association, not a lasting edge. A filing-date event study by AlphAI’s founder, published on the QuantInsti blog in August 2026, followed 7,405 C-suite open-market purchase filings from January 2022 to June 2026, entering each on the session after the Form 4 became public. The average return against SPY was +0.53% on that session and +1.01% over five sessions; at 21 and 63 sessions the confidence intervals include zero. Entering on the transaction date instead of the filing date uses information that was not yet public and overstates the result.

Cluster buys

Companies where several different insiders bought on the open market in one run of purchases, newest filing first. Plan purchases, offering allocations at one price and the same trade reported through two owners are left out, so the count is people who decided to buy. The same list is available to developers at /api/news/insider/clusters/.

CEO and CFO stock purchases

Open-market buys of $25,000 or more by chief executives and chief financial officers, newest filing first, from the last 30 days. 10b5-1 plan purchases and shares bought in an offering, a placement or a negotiated block are left out, so every row is an executive deciding to buy at the market price. A filing with several fills is one row at the average price.
