NEW YORK, January 7, 2026, 18:05 EST — After-hours
Lumentum Holdings Inc (LITE.O) shares fell 1.2% on Wednesday and were little changed in after-hours trade, the session after the 4 p.m. close, after swinging between $365.47 and $402.66 in the regular session. The stock ended at $392.80 and last traded at $392.70 late after-hours, a day after rising 11.3%.
Investors have treated the optics supplier as a proxy for the plumbing behind AI data centers, and the trade has turned jumpy. Nvidia CEO Jensen Huang said at CES that the company’s next chips are in “full production,” and Nvidia said it expects Microsoft, Oracle, Amazon and Alphabet to adopt its Vera Rubin systems, Reuters reported. Co-packaged optics moves the optical connections next to the switch chips to push more data with less power. Reuters
Lumentum said it will release fiscal second-quarter results on Tuesday, Feb. 3, after the market closes and host a webcast at 5 p.m. ET. The company sells optical and photonic components used in telecom, enterprise and data-center networks, and investors will be looking for any shift in demand from cloud customers and the tone on margins.
The market has been quick to punish surprises anywhere in the data-center supply chain. Data-center cooling and HVAC stocks slid on Tuesday after Huang said “no water chillers are necessary for data centres,” and Barclays analysts led by Julian Mitchell said “one should not take their comments lightly,” Reuters reported.

Lumentum is trading near its 52-week high of $401.60 and at about 263 times trailing earnings — its price-to-earnings ratio, a common valuation gauge. About 18% of the free float is sold short, meaning those shares are borrowed for bets against the stock, and that can magnify both rallies and pullbacks.
Traders now circle Feb. 3, when the company reports after the close and takes questions on its call; guidance will matter more than the quarter in a stock moving like this. The $400 area is the level many will be watching into the release.
