On October 19, Lumentum rose 3.31% in Pre-Market Trading, trading at $852.89 per share, with turnover of $9.79 million.

The move aligned with a technical rebound across optical networking names as the recent high-level pullback in the group showed signs of easing, helping sector sentiment recover.

Recent reports said Lumentum has sold out AI server optical component capacity through early 2029, while management indicated roughly 70% of demand for some products may remain unmet through 2027. Supporting the backdrop, analysts recently continued to favor Lumentum and Coherent on expectations that AI data center buildouts will sustain demand for Ethernet and optical communications, even after the sector's recent correction. Peer pre-market gains in Applied Optoelectronics, Ciena, Arista Networks, and Nokia also pointed to a broader group recovery.
