2 Optical Stocks to Buy After Tuesday's Selloff

AI optics names sold off broadly: Lumentum shares fell 9.9% to $873.31 and Coherent fell 12.8% to $306.43 on Tuesday despite strong recent results. Lumentum reported fiscal Q4 revenue of $1.01B (+109% YoY) and guided $1.225B–$1.275B for the current quarter (+~24% at the midpoint), alongside non-GAAP gross margin of 50.4% and adjusted EPS of $3.23. Coherent posted record fiscal Q4 revenue of $2.05B (+34% YoY) with operating margin improving to 12.4% (from 0.4%) and guided current-quarter revenue of $2.2B–$2.4B with adjusted EPS of $1.85–$2.05.

Analysis

The market is treating these names like high-duration AI beta, but the operating data says they are still capacity-constrained picks-and-shovels. That matters: when demand is outrunning supply, the first move in the stock is often multiple compression, not a fundamental break. The right question over the next 1-3 months is whether hyperscaler capex commentary from the NVDA/AMZN/MSFT/GOOGL ecosystem confirms the buildout is intact; if it does, this selloff should reverse quickly because order visibility is still the scarce asset.

Relative positioning favors COHR as the cleaner rebound vehicle: it has a lower multiple, broader end-market exposure, and less dependence on a single product cycle, so it should de-rate less if the market stays nervous. LITE is the higher-beta expression of the same theme; that gives it more upside if AI demand accelerates, but also makes it the more fragile holder in any digestion phase. The second-order risk is not near-term revenue, but customer mix shifts if hyperscalers respond to optics bottlenecks by redesigning networks or pulling more supply in-house.

The contrarian point is that consensus is extrapolating “AI trade crowded” into “AI spend peaking,” which are not the same. These suppliers typically see the turn before the mega-cap spenders do, so guide-up quarters are often leading indicators rather than lagging confirmations. What would falsify the bullish setup is any cut to near-term revenue guidance, signs of backlog normalization, or a clear capex pause from the big cloud buyers over the next two earnings cycles.

Key Decisions for Investors

• Buy COHR on weakness over the next 1-2 sessions; target a 10-15% rebound if AI capex commentary stays constructive into the next round of hyperscaler earnings. Invalidate if management guides below the current revenue range or margin expansion stalls.
• Pair trade: long COHR / short LITE for 6-10 weeks. COHR offers lower valuation and broader revenue support; LITE carries more upside beta but also more downside if the market keeps de-risking AI duration.
• Use a starter long in LITE only if you want the highest torque to a renewed AI rally; size smaller than COHR and treat it as a momentum trade, not a core position. Stop out on any evidence of order digestion or a material guide-down.
• Set a watch item on NVDA, MSFT, AMZN, and GOOGL capex language over the next earnings cycle; if those budgets stay firm, add to COHR/LITE. If one or more imply a pause, reduce exposure immediately.
