Full history from EDGAR: holdings now, every transaction and Form 144 planned sales
Every trade, with what the company filed around it
Open-market buys and sales as each Form 4 states them, newest first.
How these figures work
Notes on each row are as each Form 4 states them, next to SEC Tracker's own records of the company's filings and other insiders' buys. Holding after is what the filing reports they held after the trade, with the change in their holding.
