Nvidia Soared by 39% in 2025, but Here's Another Super Semiconductor Stock to Buy in 2026

Corning is benefiting materially from AI-driven demand for data-center optical fiber, with company guidance pointing to FY2025 core revenue of about $16.3 billion (up ~13% YoY) and Q4 core revenue expected at $4.35 billion. Q3 core revenue rose 14% YoY to $4.27 billion while optical communications revenue surged 33% to $1.65 billion and enterprise optical revenue jumped 58%; core net income was $585 million (+26% YoY) with the optical segment contributing $295 million (+69%). CEO Wendell Weeks expects the data‑center fiber market could double or triple as operators replace copper with fiber, giving Corning pricing power and margin expansion; valuation (trailing adjusted EPS $2.38; P/E ~36.9) is presented as cheaper than several semiconductor peers.

Analysis

Market structure: Winners are fiber-centric suppliers (GLW) and GPU/cloud infra providers (NVDA, MSFT, META) as hyperscalers scale nodes from 100k→1M+ GPUs; losers include copper interconnect vendors and copper miners as longer-distance optical links displace copper inside and between nodes. The optical segment’s enterprise revenue +58% and Corning’s estimate of a 2–3x market imply sustained pricing power and tighter optical component supply through 2026–2028, supporting margin expansion for incumbents.

Risk assessment: Tail risks include a) rapid adoption of alternative interconnects (co-packaged optics or on-package photonics) that commoditize Corning’s product, b) order lumpy hyperscaler capex or a CPU/GPU cycle pullback, and c) export controls or a China demand shock; any of these could swing GLW ±20–40% within months. Near-term (days–weeks) expect earnings-driven volatility around Jan 28 (±5–15%); medium-term (3–12 months) depends on hyperscaler order cadence; long-term (2–5 years) is structural but sensitive to silicon-photonics substitution and vertical integration by hyperscalers.

Trade implications: Core trade is long GLW (2–3% position) for 12-month upside driven by enterprise optics growth, paired with a defensive hedge in copper exposure (short copper miner ETF COPX or 1–2% short in FCX) to capture displacement. Use options to manage earnings IV: buy a 9–12 month GLW call spread (e.g., Jan 2027 45/60) to retain upside with defined cost; consider buying NVDA exposure selectively on dips as second-order beneficiary.

Contrarian angles: Consensus may underprice supply expansion — global fiber capacity could ramp, compressing ASPs and margins after a 12–24 month window; equally, hyperscaler vertical integration (designing/custom ordering glass or optical subsystems) could redirect value away from glassmakers. Historical parallels (optical backhaul vs last-mile transitions) show long structural growth but episodic margin mean reversion, so position sizing and stop thresholds must assume a 20% downside scenario before mean reversion resumes.

Key Decisions for Investors

• Establish a 2–3% long position in GLW (size relative to portfolio) now, add up to another 2% on any post-earnings weakness >10% after Jan 28, target 12-month hold with profit trim at +30–40% and hard stop-loss at -18%.
• Buy a defined-risk GLW call spread to leverage structural growth: Jan 2027 GLW 45/60 call spread (delta skew 0.35–0.5), max loss = premium; allocate 0.5–1% of portfolio to this position to capture multi-quarter upside while limiting IV risk.
• Implement a 1–2% pair trade: long GLW vs short COPX (Global X Copper Miners ETF) 1:1 notional to express fiber displacing copper; unwind if GLW underperforms COPX by >15% over 60 days or if hyperscaler capex guidance turns negative.
• Reduce exposure by 1–2% to legacy copper/interconnect suppliers or broad commodity cyclicals (e.g., FCX/COPX) and reallocate into GLW/NVDA; if NVDA or hyperscaler guidance shows deceleration in the next 90 days, immediately cut GLW exposure by half.
