  • Futures rebound +0.4-0.7% after Thursday's broad selloff, with small caps leading the overnight bounce
  • Gold surges past $4,650 (+3.1%) while the dollar weakens — metals rally flags inflation hedging ahead of Nvidia earnings
  • 10-year yield pushes toward 4.7% as US debt crosses $40 trillion, pressuring rate-sensitive sectors

Previous Session Close

Thursday delivered a clean risk-off session. The S&P 500 dropped 0.84%, the Nasdaq 100 fell 0.72%, and the Russell 2000 took the worst of it at -1.34% — small caps continuing to absorb the brunt of rate anxiety. The Dow shed 1.27%. Healthcare was the heaviest drag, down 1.87%, with consumer discretionary close behind at -1.61%. Energy was the lone sector in the green, adding 0.27% as oil held above $87.

The VIX slipped 2.31% to 15.64, which reads oddly against a down tape. That tells you Thursday’s selling was orderly rotation, not panic liquidation. No one was paying up for downside protection. Implied vol is still well below the 20 threshold that would signal genuine fear — this market is repricing, not breaking.

Overnight Futures & Global Read

Futures have reversed course overnight, with S&P contracts up 0.38%, Nasdaq futures leading at +0.65%, and Russell futures posting the strongest bounce at +0.74%. The pattern is textbook: Thursday’s late sellers are getting squeezed into the Friday open, with beaten-down growth and small caps attracting the first bids.

Dow futures are up 0.42%, suggesting the bounce is broad rather than concentrated in a handful of mega-caps. If this holds through pre-market, expect the open to gap modestly higher — but the real test is whether buyers defend the gap or fade it by midday.

Commodity & FX Setup

Gold is the standout overnight, surging 3.11% to $4,657. Silver is close behind at +2.95%, and copper is up 2.31%. A synchronized metals rally like this, paired with a weakening dollar (DXY down 0.26% to 98.64), points to institutional hedging against fiscal risk — and the $40 trillion US debt headline landing today gives that trade a clear catalyst.

The euro is firming at 1.171 (+0.27%) and sterling is stronger at 1.366 (+0.43%), both benefiting from the soft dollar. WTI crude slipped 1.02% to $86.93, which limits any tailwind for energy despite Thursday’s relative outperformance. For materials stocks, copper above $6.60 keeps the growth-proxy signal intact even as equities wobbled.

Catalyst Watch

Three items from the headline tape worth tracking into the session:

Nvidia earnings overhang. NVDA reports next week, and the pre-positioning is already visible — hedge funds are doubling down on Big Tech after summer volatility, per the latest fund flow data. The stock’s ability to “rescue a stalling market” (as one headline frames it) means any guidance leak or analyst note today could move the entire Nasdaq.

US debt at $40 trillion. The Treasury just crossed the $40T mark, and Washington is signaling a crackdown. With the 10-year yield pushing 4.7% (+0.92% overnight) and the 30-year above 5.23%, any concrete fiscal tightening rhetoric today hits rate-sensitive names directly — financials, REITs, and utilities.

Coherent (COHR) earnings. The Q4 transcript is out. Coherent sits at the intersection of AI infrastructure and optical networking — its results give a read on datacom spending trends heading into Nvidia’s report.

Bottom Line

The setup leans cautiously risk-on into Friday’s open. Futures are green, VIX is subdued, and the overnight metals rally is more about fiscal hedging than equity fear. The level to watch is whether the S&P holds Thursday’s low and builds above it — a fade below would turn this bounce into a trap. The single most important driver today is the rates complex: if the 10-year keeps climbing toward 4.75%, the futures bounce won’t stick. At Luna3, we’re watching whether the Nasdaq can reclaim Thursday’s opening print — that’s where conviction separates from short-covering.
