Coherent, Lumentum, and Corning stocks surge after Nvidia CEO Jensen Huang endorses optical components for AI data centers

Coherent stock rose 17.66% to hit an all-time high, Lumentum shares gained 14%, and Corning shares gained 13.4% on Tuesday. Marvell shares rallied 33%, adding $62.4 billion to its market capitalization in a single day.

At Computex in Taipei, Taiwan, Huang stated the strategy for scaling AI infrastructure: 'use copper wherever you can' but 'use optics wherever you must,' with optical networks handling scale-up, scale-out, and scale-across tasks between AI chips, servers, and racks.

Year to date, LITE has surged 173%, while COHR and GLW have gained about 126% each, as investors bet that optical components and photonic networks will become essential for moving massive amounts of data in AI data centers.
