During the selected 365-day window, GLW insider trading registers a bearish signal with -$112.2M in net open-market flow across 24 reporting insiders. The latest available Form 4 was recorded on 2026.09.30.
Open-market purchases minus open-market sales produce a negative net flow of $112.20M. 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 WEEKS WENDELL P (Director, Chairman, CEO and President). Form 4 activity provides useful ownership context, but it should not be treated as a standalone prediction of future price performance.
