US stocks fall a fourth day as WTI tops $100 and the 10-year hits 4.94%

S&P 500 close: 7,591.70 (-0.58%) Sectors: 2 higher / 9 lower Sentiment: bearish

The S&P 500 closed at 7,591.70 on 10 September 2026, down 0.58%, as WTI crude rose 8.20% to US$103.93 and the US 10-year yield added 11 bps to 4.94%, a 52-week high. NAVN.US fell 21.75% to $20.26, the session's deepest single-name loss, after a fiscal Q2 revenue beat of $232.8m ran into margin questions and a same-day BoomPop acquisition. August producer prices, released at 8:30am ET, rose 0.4% on the month and 5.4% over the year, with final-demand goods up 1.1% as the crude move fed into producer inflation.

What moved the index

  • Technology, about 48 bps of the 58 bps decline. XLK.US -1.41% at roughly 34% index weight. Semiconductors led: SMH.US -2.44%, MU.US -4.90%, AMD.US -3.36%, NVDA.US -2.37%. Semis carry the index's richest multiples and reprice first when the 10-year moves.
  • Rates and crude. The 10-year at 4.94% and WTI at US$103.93 trace to the same August PPI print: goods prices up 1.1% in a single month, headline up 5.4% year on year, core less foods, energy and trade services up 4.7%.
  • Copper miners, about 2 bps of index and the widest single-sector move. Copper futures fell 5.26% to US$6.53/lb after Reuters reported the White House has not settled on refined-copper tariffs, two days after the metal set a record high. FCX.US -6.59%, SCCO.US -7.23%, HBM.US -7.53%, TECK.US -6.31%, XLB.US -1.23%.
  • Offsets worth about +33 bps. AAPL.US +3.56% at roughly 7.5% weight carried about +27 bps on its own, day two after the 9 September product event. XLC.US +0.60% added about +6 bps behind CHTR.US +4.98% and RDDT.US +6.08%.

Technology alone covers about 48 bps of the 58 bps move, and Apple plus communication services handed back about 33 bps of it. The remaining drag is spread thin: XLF.US -0.33%, XLV.US -0.55%, XLY.US -0.44%, XLI.US -0.72%, XLU.US -0.98%. The Russell 2000 fell 1.04% to 2,890.95, twice the S&P 500's decline.

Session highlights

  • VIX 17.84, up 8.38%, its highest close across the current four-session equity decline.
  • ORCL.US -5.38% to $152.94 into its own after-the-bell report, the largest technology drag in the index.
  • Gold fell 2.29% to US$4,358.50/oz and the dollar index rose 0.27% to 99.08, both moving against crude at +8.20%.
  • Brent US$108.95, up 7.65%. Iran said it would sustain attacks on Gulf shipping against the US naval presence.
  • 2 of 11 S&P 500 sectors closed higher: XLC.US +0.60% and XLP.US +0.05%.

  • Best: Communication Services (XLC.US +0.60%)
  • Worst: Technology (XLK.US -1.41%)
  • Dispersion (best minus worst): 2.01 pts
