Nvidia Is Investing Billions in These Two Artificial Intelligence (AI) Players. Now They're Joining the S&P 500

Nvidia pledged $2.0B each to Lumentum and Coherent as part of multiyear strategic partnerships, and both suppliers were added to the S&P 500 effective March 23. Lumentum and Coherent shares have risen ~932% and ~279% over the past year and currently trade at ~45x and ~34x next‑year EPS, respectively. Inclusion into the S&P 500 will force index-tracking flows that should support near-term prices, while Nvidia’s purchase commitment secures critical optical interconnect components for large-scale AI data centers.

Analysis

The combination of strategic capital from a dominant AI platform and the liquidity effects that follow index reconstitution creates a two-stage price impulse: an immediate, mechanically-driven demand shock followed by a fundamentals-driven re-rating as supply chains and contract economics are revealed. Expect intra-sector dispersion — data-center infrastructure OEMs with broader TAM exposure (thermal, power, racks) will see steadier, less binary flows than single-product optics suppliers whose revenue is highly correlated to a handful of large hyperscalers.

Second-order supply-chain dynamics matter: large, long-term purchase commitments shift bargaining power toward the buyer for future cycles (volume discounts, priority allocation) while creating near-term capacity tightness for optics makers that can inflate gross margins temporarily but invite competition and capex responses within 12–24 months. Equally important is capital market plumbing — index-driven inflows compress free float, raise borrow costs, and can create option pinning into rebalances; these technicals increase short-term volatility and can make downside alpha from mean reversion more accessible than upside from further momentum.

Risks and catalysts are asymmetric by horizon. Over the next 2–6 weeks, mechanical ETF/index flows and positioning changes will dominate price moves; catalysts that could reverse the move quickly include revised purchase schedules, a visible acceleration of in-house optics development at platform players, or macro-led capex retrenchment. Over 3–24 months, watch unit economics: if supplier order books convert into higher S&M and capex to meet demand, margin expansion may evaporate and multiples could compress even if revenues continue to grow.

Key Decisions for Investors

• Long VRT (Vertiv) — tactical 6–8 week trade to capture technical/index-related inflows: initiate a 2–3% portfolio notional long, use a trailing stop at -8% and target +20–30% if flows persist. Rationale: broader product set and more stable revenue mix should make VRT a lower-beta beneficiary of data-center capex than single-product optics names.
• Pair trade: short LITE/COHR vs long VRT — medium-term 3–9 month horizon to arbitrate valuation dispersion. Position sizing: 1:1 notional short of optics supplier(s) hedged by long VRT; finance with 3–6 month put spreads on the short leg (limit downside) and keep total portfolio exposure <3% notional. Target a 25–35% relative mean reversion; stop if the short leg outperforms the long by >15% on momentum grounds.
• Long NVDA via diagonal call spread (buy 12–18 month LEAP calls, sell near-term calls into expected short-term volatility spikes) — secular upside capture with funded carry from short-term premium. Allocate 1–2% notional, set plan to roll sells monthly into expiries after major rebalancing windows; max loss = option premium, target asymmetric upside >3x premium over 12–24 months.
• Vol/flow squeeze micros: monitor borrow and IV on optics names and buy 1–2 week ATM put calendars after options IV compression post-rebalance — if IV drops >25% from peak, sell a short-dated call to finance longer-dated protection. Use this as trade-to-trade alpha rather than strategic exposure; capital at risk per trade <0.5% notional.
