S&P 500 closes 0.4% higher as AI shares rebound

The S&P 500 ended Tuesday, November 3, 2026, higher as a rebound in major AI-related stocks helped the benchmark recover from recent technology-driven declines. According to The Associated Press, the index gained 27.52 points, or 0.4%, to close at 7,568.92. The move came even though more stocks in the index fell than rose.

AI shares support the benchmark

Nvidia and other AI-related companies provided support after several weeks of sharp swings and selling pressure. Their rebound helped offset losses in Apple, which declined after warning that rising memory-chip costs could reduce its profit margin per dollar of revenue in the holiday quarter.

The session therefore remained uneven beneath the headline gain. The technology complex continued to face scrutiny over elevated valuations and the scale of spending on artificial-intelligence infrastructure, while investors assessed whether future earnings and cash generation will justify those investments. A stronger performance by influential AI shares was sufficient to lift the broad index, despite weakness across a larger number of constituents.

Oil and election uncertainty in focus

Falling oil prices were another feature of the session. Earlier in the day, Reuters reported that crude prices were extending their decline as investors monitored developments involving a potential U.S.-Iran peace agreement. Lower energy costs can ease concerns about inflation, although the market's reaction also depended on company-specific earnings and technology-sector positioning.

Investors were simultaneously awaiting the outcome of U.S. midterm elections. The vote introduced uncertainty around future fiscal policy, regulation and government spending, while a possible change in congressional control added to the importance of subsequent market signals from Treasury yields, the dollar and economically sensitive sectors. Those political considerations formed a backdrop rather than a clearly isolated cause of the index's daily move.

Market context for investors

The S&P 500's gain was narrower than the headline suggests because participation was weak: the Associated Press reported that the majority of constituents declined. The Nasdaq Composite rose 0.8%, while the Dow Jones Industrial Average fell 0.4%, underscoring the continued concentration of market performance in selected technology and AI-related names.

For investors, the session points to a market still balancing support from resilient technology leaders against concerns about valuation, financing costs and the eventual returns on AI expenditure. The index's close provides a firmer daily result, but not by itself a signal that the recent technology-sector volatility has ended. Further earnings reports, election developments and energy-price moves remain relevant to the next trading session. More coverage is available on the S&P 500 topic page.
