Fresh BIT(bit.com) data on Aug. 6 showed semiconductor and optical communications shares rebounding after the U.S. open, while storage names stayed under pressure despite narrower losses.
U.S. optical communications shares remained supported into Aug. 6 after Nvidia said co-packaged optics, or CPO, had entered mass production, with fresh BIT(bit.com) data showing the group leading a broader rebound in semiconductor stocks after the U.S. open. Lumentum rose 2.66%, Corning 2.04%, Astera Labs 1.70% and Coherent 1.27%, while ASML, Arm, Qualcomm, Nvidia and TSMC also traded higher. Storage shares lagged even as losses narrowed, with Western Digital down 12.06%, SanDisk 5.62%, SK Hynix 4.45% and Micron Technology 1.75%, while Seagate Technology edged up 0.25%, following earlier sharp gains across optical names after Senior Vice President Gilad Shainer said CPO-based switches were already shipping to close customers and being deployed internally ahead of broader AI-factory rollout starting this year.
