- Lumentum ended Friday up 4.75% at $386.11, outpacing a modest gain in the S&P 500. MarketWatch
- Optical hardware peers Coherent, IPG Photonics and nLIGHT also climbed, echoing strength in AI-linked infrastructure names.

Lumentum Holdings Inc shares jumped 4.75% on Friday to close at $386.11, lifting the optical components maker at the start of 2026. MarketWatch
The move matters because investors reopened the “AI infrastructure” trade on the first trading day of the year, even as megacap tech lagged. Chipmakers led the rebound, with the Philadelphia Semiconductor Index up 4%, a backdrop that often pulls optical networking suppliers higher as well. Reuters
Lumentum is closely watched in that theme because it sells optical and photonic components used in cloud data centers, including products tied to artificial intelligence and machine learning workloads. When traders rotate back into AI hardware exposure, the stock tends to trade in the same conversation as parts of the broader “picks-and-shovels” complex. Reuters
Peers moved in the same direction on Friday. Coherent gained 5.27%, IPG Photonics rose 4.53% and nLIGHT added 2.27%, based on end-of-day pricing.
Lumentum swung between $374.87 and $392.00 during the session, after opening at $379.38, with about 2.82 million shares traded, market data showed. Lumentum Investor Relations
Joe Mazzola, head of trading and derivatives strategist at Charles Schwab, described the tape as a “buy the dip, sell the rip” market as investors look for entry points after pullbacks. Reuters
Macro catalysts are front and center into Monday. Reuters reported traders are focused on the Federal Reserve’s policy path and a run of labor-market data due next week, which could shift rate expectations and risk appetite. Reuters
Lumentum operates across Cloud & Networking and Industrial Tech, supplying optical networking components as well as lasers used in industrial applications, according to a Reuters company profile. Its Cloud & Networking portfolio includes products for data center interconnect — the fiber links that connect large data centers over distance — and for AI/ML workloads. Reuters
The next company checkpoint is earnings. Lumentum previously guided fiscal second-quarter net revenue to $630 million–$670 million and non-GAAP operating margin to 20%–22%, according to its latest outlook disclosed with results earlier in the fiscal year. SEC
Before the next session, investors are also framing expectations for the next report, which is widely penciled in for early February. Barchart’s calendar shows a next earnings release date of Feb. 5, with an average earnings estimate of $0.97 per share for the current quarter. Barchart
Watchpoints into that update include whether demand tied to AI data-center buildouts remains strong enough to support the company’s margin targets, and whether supply constraints or pricing pressure emerge as volumes ramp. The guidance reset for the quarter ahead is likely to drive the next leg for the stock more than Friday’s broad risk-on tone. SEC
Technically, Friday left traders with clear near-term reference levels: the session high near $392 as an upside barometer and the day’s low near $375 as a downside line in the sand. A break either way in the next regular session would test whether Lumentum’s early-2026 bid is a sector-wide rotation or the start of another run in AI-linked optics. Lumentum Investor Relations
