During the selected 180-day window, SNDK insider trading registers a bearish signal with -$10.9M in net open-market flow across 7 reporting insiders. The latest available Form 4 was recorded on 2026.08.21.
Open-market purchases minus open-market sales produce a negative net flow of $10.86M. 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 Ilkbahar Alper (EVP, Chief Technology Officer). Form 4 activity provides useful ownership context, but it should not be treated as a standalone prediction of future price performance.
