On June 16, Applied Optoelectronics declined 5.99% in regular trading, trading at $180.37/share, with turnover of $597 million. The stock gave back gains from the prior session's rebound as ongoing concerns over co-packaged optics (CPO) deployment timelines continued to weigh on the sector.

The decline follows a SemiAnalysis report asserting that large-scale CPO adoption could be delayed to 2028 or even 2029, significantly later than the market's prior consensus of 2027 full-volume deployment. The report cited system-level yield rates potentially as low as 19.4%, dampening aggressive near-term expectations. Although NVIDIA executives publicly confirmed CPO switch deployments and on-schedule mass production plans the previous day — sparking an 8.12% rebound — the relief proved short-lived as skepticism over production feasibility persisted.

Within the Communication Equipment sector, peers declined in tandem: Lumentum fell 4.81%, Ciena dropped 4.11%, and Nokia Oyj lost 2.99%, while Arista Networks gained 0.96% and Cisco was flat at -0.03%.
