Lumentum and Coherent lead AI optics trade amid divergent performance

Optical networking companies are seeing divergent market performance as investors shift focus toward specific components of the AI infrastructure buildout. Lumentum Holdings recently saw a nearly 10% increase, while Coherent advanced 6.9%. In contrast, Corning experienced minimal movement, gaining only 0.4% despite its role in providing optical fiber and connectivity infrastructure.

The performance gap reflects different market exposures. Lumentum offers concentrated exposure to high-speed optical transceiver components, which are critical for data center accelerators. Corning maintains a broader portfolio including fiber, but faces different investor sentiments, including concerns regarding a $2 billion equity distribution agreement established through Goldman Sachs.

Despite these differences, industry leaders like Lumentum and Coherent have been identified by Deutsche Bank as top AI hardware picks. As AI models demand massive data movement across server clusters, the physical hardware and optical pathways provided by these established suppliers remain essential to overcoming interconnect latency and electrical grid constraints.
