Insider Transactions

Insider trading summary

Stock Pro

Returns aggregated insider trading statistics for the last 3, 6, and 12 months. Only includes significant open-market trades (purchase and sale codes P/S) by officers and directors. Transactions are deduplicated across co-owners — each physical trade counted once, prioritizing the most senior filer (officer > director > 10% owner). Excludes trades with price >= $100,000 (SEC data entry errors) and Form 5 amendments when a Form 4 exists for the same trade.

uniqueBuyers and uniqueSellers count distinct insiders — cluster buying (multiple insiders buying) is a stronger signal than one person buying repeatedly.
