On July 21, Corning rose 4.17% in pre-market trading, trading at $159.25/share, with turnover of $2.4824 million.

On the news front, TSMC's Chief Financial Officer stated that the downstream chip market continues to see multi-year super demand waves, with long-term structural demand in AI continuing to surge, lifting sentiment across the semiconductor and optical communications supply chain. UBS also previously issued a forward-looking report expressing optimism on optical communications sector momentum. The broader optical communications sector rallied in pre-market trading, with Coherent up over 4%.

Corning had previously declined approximately 38% from its late-June historical high after JPMorgan placed the stock on its negative catalyst watch list, citing elevated valuation levels rather than fundamental concerns. The bank maintained its Neutral rating while raising its target price to $200. Citigroup separately raised its target price to $240, maintaining a Buy rating. Following the concentrated valuation compression, oversold rebound momentum continues to build.

Corning is scheduled to report Q2 earnings before market open on July 28, with consensus expecting adjusted EPS of $0.76. Earnings delivery will directly influence subsequent price action.
