Stock Market Today, Dec. 26: S&P Notches New High As Investors Digest Nvidia-Groq Deal

U.S. major indexes eased marginally in thin post‑Christmas trade with the S&P 500 slipping 0.03% to 6,929.94, the Nasdaq down 0.09% to 23,593.10 and the Dow off 0.04% to 48,710.96, though the S&P hit an intraday record and is up ~2.3% for the week. Nvidia ticked higher after agreeing to buy roughly $20 billion of assets from AI startup Groq, while materials names (Freeport‑McMoRan, Southern Copper) outperformed as precious metals surged—spot gold near $4,550/oz and silver above $77/oz—fueled in part by ongoing geopolitical tensions; Standard Lithium fell about 6%. The mix of AI M&A and a powerful metals rally is supporting risk assets, but thin liquidity and the potential for a small adverse shock argue for caution heading into year-end.

Analysis

Market structure: AI leadership (NVDA) and industrial commodities (FCX, SCCO) are the clear winners as capex and inventory re‑allocation favour silicon/compute and base metals while speculative battery juniors like SLI are being punished; expect a rotational bid into producers with cashflow and away from pre‑revenue/resource developers. The Nvidia–Groq asset deal (~$20B) concentrates IP and scale in fewer hands, increasing pricing power for high‑end inference chips and raising barriers to entry over the next 12–36 months, supporting valuation premium near term but amplifying systemic concentration risk.

Risk assessment: Key tail risks are regulatory (export controls/antitrust on AI vendors), a sharp rise in real yields that kills precious‑metals momentum, and integration or tech deployment slippage at NVDA — each could erase 10–30% of implied excess returns within 1–6 months. Short‑term (days–weeks) expect thin liquidity and volatility spikes around macro prints (next 2 US CPI/PCE releases); medium (3–12 months) depends on AI capex cadence and copper demand; long (1–3 years) hinges on sustained AI enterprise spending and battery/EV cycles.

Trade implications: Prefer concentrated asymmetric trades: tactical long NVDA exposure via defined‑risk options (6–9 month call spreads) sized 2–4% portfolio; overweight FCX/SCCO (2–4% each) to play commodity tightness and geopolitical safe‑haven flows, with stop‑losses at 12%. Short selective lithium juniors (e.g., SLI) sized 0.5–1% or buy 3‑6 month puts because capital flight to gold/copper undermines speculative EV metal names; hedge equity beta with 2–3% long gold (GLD) or miners.

Contrarian angles: The consensus framing of 2026 as “year of AI” understates mean‑reversion risk — NVDA is priced for flawless execution and any 1–2 quarter slowdown could trigger >20% drawdowns; conversely gold’s spike to ~$4,550 (spot) may be overbought if real yields rebound >150bp. Historical parallels: 2010–12 commodity spikes that reversed after rate normalization suggest trimming miners into rallies and using pullbacks to add selectively, not buy-and-hold at peaks.

Key Decisions for Investors

• Establish a 2–3% portfolio position long NVDA via a 6–9 month call spread (buy 10–15% OTM call, sell 40–50% OTM call) to capture further AI M&A upside while capping premium; take profits at 30–40% option ROI or delta-adjust/roll down if NVDA rallies >25% in 60 days.
• Add 2% positions each in Freeport‑McMoRan (FCX) and Southern Copper (SCCO), scaling in on any 5% pullback; set hard stops at 12% below entry and target 20–35% upside over 6–12 months as copper/gold tightness persists.
• Initiate a small 0.5–1% short or buy 3‑6 month puts on Standard Lithium (SLI) to play the rotation away from speculative battery juniors; upward trigger to cover/flip long if SLI drops >20% or lithium prices show sustained month‑on‑month recovery.
• Deploy a 1.5–2% hedge in GLD or GDX (miners) to protect equity downside during geopolitical risk spikes; add another 0.5% if spot gold breaks above $4,600 (momentum threshold) and unwind if US real yields rise >150bp from current levels within 90 days.
• Avoid broad tech longs beyond NVDA concentration until two confirming catalysts arrive: (1) next NVDA earnings show sustainable enterprise AI revenue growth (sequential QoQ uptick ≥20%), and (2) no major export/regulatory action in 60 days; use this window to rebalance into commodity producers.
