Corning (NYSE: GLW) delivered a Q2 2026 earnings beat on Tuesday. But if shareholders thought it would break the stock’s slide, they were mistaken. Shares tumbled 12% that day, extending a slide that has already knocked the stock down 50% over the past 30 days.
Even after that drawdown, GLW remains up about 100% over the past year. That’s down from a peak gain near 250% at its June high, but still a reminder of just how much froth had built into the name before this reset began.
