CME insider buying and selling over the past year

Over the past year CME GROUP INC. insiders filed 13 open-market Form 4 trades — 2 purchases worth $510.1K and 11 sales worth $14.79M — which makes them net sellers by $14.28M.

Only 2 of the 11 sales were flagged as Rule 10b5-1 plan trades, so most selling was discretionary rather than pre-scheduled. Activity clustered in 2026-03 (5 trades) and 2026-02 (3 trades); the latest filing in this window is dated 2026-09-14. The average open-market sale price was $286.07; the last close of $293.87 is 2.7% above that level, so sellers left upside on the table. The single largest trade was a sale of 25,000 shares worth $6.74M on 2025-12-11. Since the most recent filing the stock has moved +4.8%, from $280.46. Insiders paid an average of $294.50 per share for their open-market purchases; against the last close of $293.87 that cost basis is under water at -0.2%.
