On June 26, Applied Optoelectronics fell 7.6% in pre-market trading, trading at $131.0/share, with turnover of $7.3556 million. The decline reflects continued pressure from bearish expectations surrounding Co-Packaged Optics (CPO) technology commercialization timelines.

On the news front, a SemiAnalysis report previously indicated that large-scale CPO deployment may be delayed to 2028 or even 2029, with system-level yields potentially as low as approximately 19.4%, far below market expectations for near-term rapid volume growth. Although NVIDIA responded that its CPO switches will begin mass production in H2 as planned, Morgan Stanley's judgment that CPO volumes may fall short of expectations aligns with the bearish view, intensifying bull-bear divergence. The broader optical communication sector saw widespread weakness, with Lumentum down 3.59%, Ciena down 2.82%, Nokia down 3.08%, and Arista Networks down 1.78%.

As a high-beta name with significant prior gains, AAOI is particularly sensitive to reassessments of advanced technology commercialization timelines. The market is increasingly differentiating within the AI optical communication space based on order certainty, customer binding, and valuation positioning.
