On July 2, Lumentum Holdings fell 3.22% overnight, trading at $776.04/share, with turnover of $21.8445 million.

On the news front, the optical communications sector continued to face broad selling pressure, with communication equipment stocks weakening collectively. Within the sector, Applied Optoelectronics fell 5.02%, Nokia dropped 2.87%, and Ciena declined 2.47%, reflecting significant sector-wide linkage effects that intensified downward pressure on individual names.

Additionally, an independent research institution previously published a report indicating that co-packaged optics technology mass production timelines may be pushed back to 2028 or even 2029, with system-level yields at approximately 19%, far below commercially viable production standards. This fundamental concern over CPO delay has continued to suppress sentiment across the optical communications space, as the market reassesses expectations around AI-driven optical networking demand, focusing more closely on customer relationships, order visibility, and actual CPO deployment timelines.
