On September 9, Lumentum rose 3.14% in regular trading, trading at $1,009.50/share, with turnover of approximately $360 million. The stock extended its strong momentum following a surge of over 11% in the prior session.

On the news front, the optical communications sector continued to benefit from multiple bullish catalysts. Goldman Sachs significantly raised its global optical module shipment forecast, citing AI computing architecture upgrades that are driving accelerating demand for 1.6T and 3.2T high-speed optical modules, with 800G and above becoming the primary growth driver. The market for high-end optical modules is projected to climb from $45.2 billion to $129.5 billion between now and the next two years. On the institutional side, Deutsche Bank initiated coverage on Lumentum with a Buy rating and a $1,200 price target, while Evercore ISI launched coverage with an Outperform rating and a $1,100 target. The analyst consensus mean target stands at approximately $1,143. Additionally, Lumentum's order backlog reportedly exceeds two years, with optical chip delivery remaining in tight supply, validating sustained fundamental strength across the sector.
