Senior VP & CHRO Michelle Gullo sells ~1M in GLW shares; stock near 52-week highs after sharp rally
Michelle Gullo, Corning's Senior Vice President and Chief Human Resources Officer, sold roughly 1 million dollars worth of company shares on a single trading day. The sale represents a meaningful portfolio reduction—roughly one-eighth of her holdings. The timing is notable: Corning's stock has rallied sharply and now trades at its 52-week highs after a sustained climb, and Gullo's sale occurred precisely at that peak. From a company perspective, Corning is financially healthy—profitable with growing revenue—and trades on a stretched valuation multiple. Gullo's prior three years of Form 4 activity show she has sold shares on the open market multiple times before, so this is not her first disposition, but the size and price point distinguish it from routine executive activity. The sale of company shares by a sitting C-suite executive at an inflated stock price in a financially sound company is material enough for investors to monitor, though the data available does not explain her rationale.
