On September 14, Lumentum declined 3.37% overnight, trading at $902.97/share, with turnover of $3.2012 million.

On the news front, the three largest U.S. AI companies signaled intentions to slow their AI expansion pace, triggering broad-based selling across AI hardware names in off-hours trading. SK Hynix fell over 4%, Marvell Technology dropped over 4%, Corning slid over 4%, and NVIDIA dipped 2%, with Lumentum declining in tandem. Within the Communication Equipment sector, the pullback was widespread: Applied Optoelectronics fell 3.72%, Nokia dropped 3.23%, Arista Networks lost 2.17%, and Ciena declined 2.16%.

Notably, Lumentum had rallied over 14% cumulatively from September 8 to 9, fueled by Goldman Sachs raising its global optical module shipment forecast, Deutsche Bank initiating coverage with a Buy rating and a $1,200 target, and Evercore ISI launching coverage at $1,100. The sharp prior gains had built significant profit-taking pressure, amplifying the downside reaction to the AI spending slowdown signals.
