On July 7, Lumentum Holdings fell 3.59% in pre-market trading, trading at approximately $715.00/share, with turnover of $3.99 million.

On the news front, the AI optical communication sector has been undergoing sustained differentiated adjustment in recent sessions. The market is no longer simply trading on AI optical communication as a broad concept, but is instead distinguishing among stocks based on customer binding strength, order certainty, CPO (co-packaged optics) deployment pace, and valuation positioning. High-beta names in the sector face notable pullback pressure. Lumentum itself had previously dropped over 7% on June 26, over 2% in pre-market on July 1, and over 2% in after-hours on July 3, indicating intensifying short-term volatility.

Within the Communication Equipment sector, other stocks also declined broadly: Applied Optoelectronics fell 3.35%, Ciena fell 2.02%, Nokia fell 1.53%, Arista Networks fell 1.04%, and Cisco fell 0.15%.
