Insider selling is not always bearish

Insiders sell shares for many reasons: taxes, diversification, or planned trading programs. A sale alone rarely proves management is losing confidence.

What makes a sell cluster meaningful

A cluster of multiple insiders selling at once may signal a coordinated decision or at least a shared view on near-term risk. We mark these events and highlight the context.

Use signal grade, not emotion

ClusterSignal grades the pattern, but you should interpret sell clusters with the same care as buys. Always verify the reason with public disclosures.
