New York, Jan 5, 2026, 13:11 (ET) — Regular session
- Lumentum shares slid about 8% in afternoon trade after a volatile swing.
- Optical hardware peers also fell, extending a pullback across the group.
- Focus shifts to Lumentum’s next earnings update, expected Feb. 5.
Shares of Lumentum Holdings Inc (LITE.O) fell 8.1% to $354.87 on Monday, after trading between $345 and $394.48 in a volatile session. About 4.2 million shares had changed hands by early afternoon.
The slide puts one of the market’s most closely watched optics names back under pressure after a late-2025 run that pushed the stock toward record territory.
The move matters now because expectations for AI-linked data-center optics have risen fast, and that leaves less tolerance for a softer outlook when companies next report. Optical components are laser-based parts that move data inside and between cloud servers.
Lumentum’s decline tracked a broader retreat in optical networking and photonics stocks. Coherent fell 5.2%, Ciena dropped 7.6% and Applied Optoelectronics slid 9.9%.
The pullback dragged Lumentum back toward the $350 area, a near-term marker for chart watchers after the stock’s rapid climb. Resistance remains near late-December peaks.
Lumentum ended Friday up 4.8% at $386.11, close to a 52-week high of $401.60 hit on Dec. 24, Yahoo Finance data showed.
In its most recent earnings update in November, the company said fiscal first-quarter revenue rose 58% to $533.8 million and it guided for fiscal second-quarter revenue of $630 million to $670 million. “We saw year-over-year revenue growth of 58 percent,” CEO Michael Hurlston said. SEC
The company also forecast non-GAAP earnings per share of $1.30 to $1.50 for the fiscal second quarter, a measure that excludes certain costs such as stock-based compensation and acquisition-related expenses.
But the stock’s steep run has left it sensitive to any sign of slower orders, tougher pricing or execution hiccups, especially as rivals compete for the same cloud and AI infrastructure spending.
