Lumentum drops as year-end tech fade hits AI optics
Lumentum fell 4.1% to $374.87 by 12:56 p.m. ET on Dec. 29, giving back more than broader tech benchmarks in a thin, holiday-week pullback. QQQ was down about 0.8% and SPY slipped roughly 0.6% as investors trimmed exposure to heavyweight tech and AI-linked names.
The stock has become a high-beta tell for sentiment around AI data-center hardware, which makes days like this worth watching. Intraday, shares swung from $390 to $364.50; they set a 52-week high of $401.60 on Dec. 24. Even after today's slide, Lumentum is up about 366% over the past year.
Peer moves underscored the tone but were milder: Coherent eased 1.9% and Ciena slipped 2.0%.
Macro setup into the holiday
Liquidity is thinner into year-end, and U.S. markets will be shut Thursday for New Year's Day - conditions that can magnify moves in fast risers. Traders are watching this week's Federal Reserve minutes and weekly jobless claims for any shift in the rate path that supports high-growth valuations.

Why it matters for AI-optics exposure
Lumentum supplies optical and photonic components used in cloud data-center links and communications networks, plus industrial lasers. These products are core to AI and machine-learning infrastructure buildouts.
On Nov. 4, the company posted fiscal Q1 revenue of $533.8 million and pointed to momentum in data-center and long-haul markets. Management highlighted optical circuit switches and co-packaged optics as growth drivers; co-packaged optics brings optical links closer to chips to boost speed and reduce power draw.
What to watch next
- Earnings cadence: Next results are expected in early February (around Feb. 5 based on historical timing). Focus on optical transceiver demand, pricing/mix, backlog, and any supply constraints tied to AI builds.
- Margins and mix: Track gross margin vs. product mix (data center vs. telecom/industrial) and any commentary on costs and capacity additions.
- Macro sensitivity: Rate expectations for 2026 matter for high-duration tech - watch real yields into and after the minutes and claims data.
- Market structure: Liquidity is thin; expect wider ranges. Near-term levels: $364.50 intraday low as a support reference, $401.60 as recent resistance.
- Relative trades: Consider LITE vs. COHR/CIEN on fundamental catalysts; index hedges via QQQ/SPY if you're managing beta.
One strategist framed the pullback as a buying opportunity rather than the end of tech leadership. Whether that holds depends on how the Fed tone and labor data land this week - and if hyperscaler capex stays intact into Q1 prints.
Bottom line for finance teams
Size risk with the calendar in mind, assume bigger tapes on smaller volume, and prioritize catalysts: Fed minutes, jobless claims, then Lumentum's February update. For AI-optics names, execution on transceiver supply, co-packaged optics progress, and hyperscaler spend will drive the next leg.
