What Happened

Corning (NYSE:GLW) shares are up 4.82% in pre-market trading, near $164.75, after closing Wednesday at $157.18, rebounding sharply after a brutal July selloff that had been driven by valuation concerns despite strong earnings. Corning designs, manufactures, and distributes specialty glass, ceramics, and optical technologies used across telecommunications, mobile consumer electronics, and life sciences industries.

The rebound follows a new 15% tariff and minimum import price on polysilicon under Section 232, a move that benefits Corning's Hemlock Semiconductor joint venture, one of only two U.S. polysilicon producers, by protecting domestic production from Chinese competition.

Bullish Analyst Commentary Adds to Momentum

The tariff news was reinforced by bullish analyst commentary, with Truist upgrading the stock to Buy citing AI-driven optical networking demand, while other firms reiterated Buy ratings despite trimming price targets. Corning's optical Communications segment has posted eight consecutive quarters of growth, with AI-enabled optical products up 32% year over year.

Conclusion

Corning's 4.82% pre-market gain reflects renewed investor optimism following the new polysilicon tariff protections and supportive analyst commentary, as the stock attempts to recover from its worst month in 24 years.
