On July 7, Lumentum Holdings fell 3.45% in regular trading, trading at 706.6 USD/share, with turnover of approximately $263 million.

On the news front, the AI optical communication sector has entered a phase of sustained differentiation, with the market no longer simply trading on broad AI connectivity themes but instead distinguishing among stocks based on customer binding strength, order certainty, CPO deployment pace, and valuation positioning. High-beta names face pronounced pullback pressure. Lumentum 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, with short-term volatility intensifying.

Despite NVIDIA having invested $2 billion in Lumentum and established a strategic agreement to support R&D and capacity assurance, the company's elevated valuation — with a TTM P/E ratio exceeding 129 — and broader sector valuation digestion pressure continue to weigh on shares. Within the Communication Equipment sector, Arista Networks fell 4.93%, Applied Optoelectronics fell 3.62%, and Nokia fell 3.04%.
