Headlines Moving Markets

Recent macro releases offered a mixed backdrop. The second estimate for second-quarter 2026 GDP showed annualized growth of 1.5%, down from 2.1% in the first quarter, while July personal income rose 0.4%, disposable personal income increased 0.5%, and personal consumption expenditures rose 0.2%. News flow also pointed to higher Treasury yields, with the 10-year yield reaching its highest level since January 2025 as investors watched renewed Middle East tensions. In Washington, the House was expected to vote on a short-term spending measure to avoid a government shutdown.

200-day SMA705.88706.38706.91707.38707.83

Near-term pivot structure, based on 2026-08-31:

  • Resistance: 768.32 (R1), then 769.78 (R2)
  • Pivot: 766.53
  • Support: 765.07 (S1), then 763.28 (S2)

SPY reference levels from August 31 frame a nearby decision zone. The traditional pivot sits at 766.53, with support at 765.07 and 763.28, and resistance at 768.32 and 769.78. Trend measures still lean constructive on a bigger horizon, since the 20-day SMA is 769.64, above the 50-day SMA at 754.31 and the 200-day SMA at 707.83, but short-term participation has weakened.

What to Watch Next

  • Breadth first, especially whether the 32.01% reading above 20-day moving averages can stabilize after sliding from 53.88% in five sessions.
  • VIX behavior after the move to 16.34.
  • SPY around the 766.53 pivot, with 765.07 and 763.28 as nearby support and 768.32 to 769.78 as resistance.
  • Sector leadership concentration. Energy, Utilities, Health Care, and Consumer Staples outperformed while Consumer Discretionary and Technology lagged.
  • Rates and headlines tied to the 10-year yield, Middle East tensions, and the House vote on a short-term spending measure.

Bottom Line

September 1 brought a clear risk-off session, with all major indexes lower, weak breadth, and a jump in volatility. Longer-term trend readings still look firmer than short-term participation, so the next key test is whether breadth and SPY support levels begin to steady.
