US stocks opened October with modest gains, as investors weighed rising borrowing costs against the approaching corporate earnings season.
Wall Street began the fourth quarter on a positive footing, with major US stock indexes edging higher on 1 October 2026. The S&P 500 gained 0.19%, while the Dow Jones Industrial Average and Nasdaq Composite each rose approximately 0.04% after a volatile trading session.
The opening session left all four major benchmarks comfortably ahead for the year:
| Index | 1 October closing level | Year-to-date gain |
|---|---|---|
| S&P 500 | 7,666.45 | 11.8% |
| Nasdaq Composite | 26,871.60 | 15.7% |
| Dow Jones Industrial Average | 50,926.56 | 5.3% |
| Russell 2000 | 2,806.62 | 11.9% |
The small-cap Russell 2000 led the day’s gains, rising 0.35%.
Those modest index moves concealed sharper differences between industries. Among sector-tracking exchange-traded funds, energy gained 1.88% and technology advanced 1.70%, while the health-care fund fell 2.65%. The uneven performance showed that investors were being selective despite the broader market’s resilience.
The bond market remained a source of pressure. The benchmark 10-year Treasury yield briefly approached 5.34%, its highest level in 24 years, before retreating. Falling yields later in the session helped stocks recover, alongside reduced expectations of another immediate interest-rate increase.
That uncertainty follows the Federal Reserve’s 16 September decision to raise its benchmark rate by a quarter percentage point to 3.75–4.00%. The central bank said inflation remained elevated, even as economic activity and domestic spending continued to show resilience.
Corporate results now offer the next major test. Tesla reports on 21 October, followed by Alphabet and Microsoft on 28 October. Alphabet will report its third-quarter performance, while Microsoft’s release covers the first quarter of its 2027 financial year.
For technology companies, revenue growth, profit margins and capital spending will help investors assess whether large investments in artificial intelligence are delivering commercial returns. With stocks already recording substantial annual gains, earnings and management forecasts could determine whether the market’s strong start carries through the final quarter.
