Coherent shares rose 4.18% on Wednesday, April 22, 2026, as momentum in AI-related optical networking names remained strong and traders continued to position for upside. The move aligns with a recent pattern of bullish sentiment around Coherent’s role in data-center interconnect—particularly high-speed transceivers and next-generation optical architectures such as co-packaged optics.

Trading activity has shown bullish option positioning in COHR in recent sessions, including call-heavy prints flagged as unusual activity. That kind of flow can amplify upside in a fast-moving tape, especially when the underlying name already has strong momentum and a crowded AI-infrastructure narrative. (benzinga.com)

Coherent has been highlighting large, expanding opportunities tied to AI networking upgrades, including higher-speed optical module demand and co-packaged optics. The company’s OFC-era messaging framed a multi-segment growth opportunity that investors have been treating as a durable tailwind, helping support repeated dips being bought. (futurumgroup.com)

Near-term, COHR’s ability to hold gains will likely hinge on follow-through catalysts such as additional customer wins, incremental evidence that 1.6T ramps are broadening, and whether bullish positioning persists or fades. With sentiment already elevated, investors will also be sensitive to any signs of demand normalization or margin pressure across optical components.
