US Stock Market Outlook for October 2026: Three S&P 500 Scenarios

The S&P 500 entered the first full week of October near 7,723. September’s jobs report showed only 29,000 new positions, easing immediate concern about another Federal Reserve rate increase.
The next tests are inflation data, third-quarter earnings, and the Fed’s October 27–28 meeting.
Positive scenario
If inflation cools and companies deliver strong earnings, lower Treasury yields could help the market break higher. Analysts currently expect S&P 500 earnings to grow 29.5% from a year earlier in the third quarter. Under this scenario, the index could move toward 7,900–8,100.
