What happened
Corning (GLW) stock jumped more than 10% on Wednesday before ending 7.4% higher at about $120, after Jefferies started coverage with a Buy rating and called it an AI optical infrastructure play. Jefferies set a $134 price target and said Corning has changed from a glass maker tied to phones and TVs into a supplier for AI data centers. Lumentum rose about 14% and Coherent about 12%, both of which make the lasers and parts that move data using light. The group also got a lift from CoreWeave, an AI computing company whose results beat expectations on Tuesday.
Why it matters
Corning's jump shows how AI spending is spreading beyond chipmakers to companies that make the fiber, lasers and connections inside data centers. Jefferies expects Corning's optical business to grow from 2028, as fiber moves inside data center equipment. The gains are sharp but fragile: Corning still trades below its 50-day average (its average price over the past 50 trading days) of about $143.
