Headlines Moving Markets

Recent macro releases point to a slower but still expanding backdrop. The BEA’s second estimate showed real GDP rising at a 1.5% annual rate in the second quarter, down from 2.1% in the first quarter. July personal income increased $115.1 billion, or 0.4%, while personal consumption expenditures rose $36.3 billion, or 0.2%. Trade data were softer, with the U.S. goods and services deficit widening from $71.2 billion in June to $88.6 billion in July.

Near-term pivot structure, based on 2026-09-08:

  • Resistance: 768.78 (R1), then 771.49 (R2)
  • Pivot: 766.97
  • Support: 764.26 (S1), then 762.45 (S2)

For SPY, the reference pivot is 766.97, with support at 764.26 and 762.45, and resistance at 768.78 and 771.49. The 20-day simple moving average is 768.66, above the 50-day at 757.56 and the 200-day at 710.38. That leaves the near-term focus on whether price can reclaim the 20-day area or continues pressing toward nearby support.

What to Watch Next

  • Breadth first. Watch whether the 22.07% reading above the 20-day moving average can stabilize after the slide from 46.72% on Sept. 3.
  • SPY around 764.26 to 762.45 support, especially if it stays below the 766.97 pivot and the 768.66 20-day average.
  • Small caps after the Russell 2000 fell 1.32%, the sharpest decline among the major indexes.
  • Volatility trend, with the VIX now at 16.46 after rising from 14.32 on Sept. 3.
  • Energy leadership versus broader weakness, with XLE up 0.83% while XLI fell 1.51% and XLY lost 1.34%.

Bottom Line

The Sept. 9 decline looked more fragile under the surface than the headline index moves alone suggest. Index losses remained moderate, but sharply negative breadth, weaker small caps, and a rising VIX point to a market that may need better participation before tone improves.
