Movement Alert｜Lumentum Holdings Falls 3.77% in Regular Trading, CPO Mass Production Delay Concerns Compound Communication Sector Weakness

Market Focus06-29 22:03

On June 29, Lumentum Holdings fell 3.77% in regular trading, trading at $758.0/share, with turnover of $834 million, as the communication equipment sector continued to slide broadly.

On the news front, the decline was driven by two key factors. First, the communication equipment sector extended its recent weakness, with peer stocks Ciena falling 8.63%, Nokia down 4.74%, and Applied Optoelectronics declining 2.34%, amplifying selling pressure through sector-wide linkage effects. Second, independent research firm SemiAnalysis previously published a report warning that co-packaged optics (CPO) mass production timelines could be pushed back to 2028 or even 2029, citing system-level yields of only approximately 19% — far below commercialization thresholds. This fundamental concern over CPO delays has continued to suppress sentiment across the optical communications sector.

Market participants are reportedly reassessing expectations for the AI optical communications segment, with capital flows beginning to differentiate based on customer lock-in, order visibility, CPO deployment cadence, and valuation positioning rather than broadly chasing the theme.
