Insider Cluster Buys

Companies where three or more insiders bought stock on the open market within the same two weeks. One insider buying is a data point. Several buying at once, independently, is the signal that research has tied to higher abnormal returns. All open-market purchases (Form 4, code P), own money only.

No cluster buys on the board yet. The radar builds this from the live Form 4 feed, so it fills in over the next few days. Check back, or grab the daily email.

Cluster buying has historically preceded higher abnormal returns than a lone insider purchase (roughly 4–8% over 6–12 months in published studies). Historical, not a promise, and not investment advice. Built live from the SEC Form 4 feed. See also the full buy radar.
