$140.5MDuring the selected 365-day window, GM insider trading registers a bearish signal with -$233.0M in net open-market flow across 17 reporting insiders. The latest available Form 4 was recorded on 2026.08.03.
Open-market purchases minus open-market sales produce a negative net flow of $233.03M. 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 sale in the selected window was attributed to Barra Mary T (Director, Chair & CEO). Form 4 activity provides useful ownership context, but it should not be treated as a standalone prediction of future price performance.
