During the selected 30-day window, CME insider trading registers a bullish signal with +$79K in net open-market flow across 1 reporting insiders. The latest available Form 4 was recorded on 2026.09.25.
Open-market purchases minus open-market sales produce a positive net flow of $0.08M. Open-market executions represent the majority of measured nominal activity in this window, making the directional flow more representative of voluntary trading activity.
The largest open-market purchase in the selected window was attributed to SHEPARD WILLIAM R (Director). Form 4 activity provides useful ownership context, but it should not be treated as a standalone prediction of future price performance.
