On August 4, Coherent surged 11.97% in regular trading, trading at $327.3/share, with turnover of $492 million. The rally was driven by reports that the U.S. Federal Communications Commission is drafting measures to ban imports of new Chinese optical transceiver modules, aiming to protect critical data center infrastructure underpinning AI development, with officials seeking to finalize and implement the ban within the year.
The proposed prohibition directly fueled expectations of domestic substitution for U.S. optical communication manufacturers. Coherent, as a global leader in optoelectronic components, became a core beneficiary. The broader optical communication sector rallied sharply in tandem, with Lumentum up over 11%, Corning up over 8%, and Applied Optoelectronics up over 17%.
The stock had previously undergone a steep correction triggered by the Philadelphia Semiconductor Index plunging over 4% in a single session and Corning's disappointing Q3 guidance, before rebounding from a low near $222 on July 30. The company is scheduled to report fourth fiscal quarter earnings on August 12, with consensus EPS expected at $1.43.
