What changed: Updated the story to reflect a 3.2% decline driven by insider selling, profit-taking, and increased share supply, contrasting the previous focus on record highs.

Corning Inc. (GLW) shares declined by 3.2% as investors locked in gains following the stock's recent record-breaking rally. The downward pressure was compounded by an increase in share supply stemming from equity awards that vested around mid-April. Furthermore, insider trading data revealed significant selling activity by company executives over the past six months, with no recorded purchases during the same period. Investors are currently digesting the latest annual report and proxy materials amid a broader sector rotation linked to optical connectivity demand for AI applications. This pullback marks a shift in sentiment as the market balances high valuations against new supply and executive divestment.
