Insider Transactions

Insider transactions

Stock Pro

Returns insider transactions (Form 4/Form 5) for officers and directors. Transactions are deduplicated across co-owners and filings, each physical trade appears once, prioritizing the most senior filer (officer > director > 10% owner).

Excludes trades with price >= $100,000 (SEC data entry errors). Form 5/5A amendments are excluded when a corresponding Form 4/4A exists for the same trade.
