On September 16, Lumentum rose 3.1% in pre-market trading, trading at approximately $864.26 per share, with turnover of $20.63 million. The stock is staging a technical rebound following a sharp single-day decline of over 7% in the prior session.

On the news front, the previous trading day saw broad-based selling across the optical communication sector after major AI companies signaled a slowdown in AI infrastructure expansion. Lumentum plunged more than 7% to close near $847, while peers Coherent and Corning dropped over 9%, and Ciena fell over 8%. The Philadelphia Semiconductor Index posted its largest single-day decline since July 1. Following a full session of risk repricing, sentiment began stabilizing in after-hours trading, where Lumentum recovered over 1%. The current pre-market session extends that recovery, with Coherent up over 2.5%, Marvell Technology up over 1.7%, and Corning up over 1.7%. Notably, Lumentum had rallied over 14% between September 8 and 9, fueled by Goldman Sachs raising optical module shipment forecasts and multiple banks initiating coverage with buy ratings, which had built significant near-term profit-taking pressure ahead of the pullback.
