Stocks with Insider Cluster Buys
A cluster buy is when three or more corporate insiders — officers, directors, or 10% owners — independently purchase their own company’s stock in the open market within a short window. It’s one of the highest-signal patterns in insider data: single trades can be personal, but clusters usually reflect a shared view that the shares are cheap. Below are 36 tickers across the 3200-stock US large- and mid-cap universe where at least 3 insiders have filed Form 4 purchases in the last 60 days — and unlike every other free scanner, you can move both of those numbers yourself.

How to read cluster buys
Academic research on insider trading — most notably work by Nejat Seyhun and later Cohen, Malloy, and Pomorski — consistently finds that routine insider trades carry little predictive value, but opportunistic clusters of open-market purchases outperform the broad market over the following 6–12 months by a meaningful margin. The intuition is simple: insiders have day-to-day visibility into orders, pipeline, and cash flow that outsiders don’t. When several of them independently write personal checks for their own company’s stock, that consensus is more informative than any single trade.
What to weight when scanning this list: role matters — a CEO or CFO buy is a stronger signal than a board director’s, because officers see the numbers first. Size matters — a $50,000 director buy after a $2M grant last month is noise; a $500,000 CEO buy that meaningfully raises their personal exposure is signal. And context matters — cluster buys after a large sell-off, an earnings miss, or a sector rotation tend to precede reversals more reliably than clusters at all-time highs.
This page rebuilds twice a week from SEC Form 4 filings pulled via Finnhub. Our published cluster definition uses a 60-day rolling window and requires at least 3 distinct insiders per ticker; the controls above re-run that same arithmetic at a window and insider count you choose. Only open-market purchases (transaction code P) count — awards, gifts, tax-withholding sales, and option exercises are excluded because they don’t reflect a real capital decision by the insider.
