Insider selling is immaterial relative to market cap—no bearish signal. Monitor upcoming earnings and guidance for fundamental changes, but this cluster alone does not warrant action.
Price Chart
Executive Summary
A cluster of 8 Corning insiders sold shares totaling $23.45M over May 7-14, 2026. However, this represents only ~0.013% of the company's $179.3B market cap, well below the threshold for material insider activity. The selling appears to be routine diversification and is not indicative of bearish sentiment.
