Watches for company executives buying their own stock together
When three or more executives at the same company buy their own stock within a two-week window, it's a strong collective signal that they believe the company is undervalued — stronger than any single insider trade. This signal buys when the cluster forms. Each purchase must be at least $25,000 and recorded on SEC Form 4.
Kill Criteria
Mechanism (Technical)
Insider buying, when clustered, is one of the cleanest leading indicators documented in the literature (Cohen, Malloy, Pomorski 2012 — 'Decoding Inside Information'). Single-insider buys have noise; multiple independent insiders buying within a narrow window signal shared conviction that isn't explained by scheduled 10b5-1 plans or executive compensation mechanics. We focus on open-market purchases (transaction code 'P'), not option exercises or automated plans, and require geographic/role independence where derivable.
