Recent third-quarter earnings momentum, with consensus expectations for 27-30% year-over-year S&P 500 EPS growth concentrated in technology and AI-related firms, remains the dominant driver of index levels near 7,620-7,630 as of late October 2026. Elevated Brent crude above $110 per barrel, 10-year Treasury yields exceeding 5.3%, and the Federal Reserve’s September rate hike to the 3.75-4.00% range have tempered gains following the early-October record close near 7,845. Traders are monitoring the October 28 FOMC decision, continued earnings reports, and the December 9 meeting with updated economic projections for signals on the policy path through year-end.
