Mobia Medical, Inc.

A cluster buy happens when two or more company insiders — executives, directors, or major shareholders — purchase stock independently within a short window. Unlike a single trade, a cluster signals broad internal conviction from people with direct knowledge of the business.

The conviction score (0–100) weighs the number of buyers, total dollars invested, insider seniority, timing tightness, and company size. Higher scores indicate stronger, more concentrated conviction.
