U.S. stocks posted a mixed October as the S&P 500 Information Technology sector fell 6.8%, while gains across most other sectors kept the benchmark’s monthly loss below 1%, CNA reported.
CNA said nine of the index’s 11 sectors rose and more than 70% of its constituent stocks advanced. The Information Technology sector’s decline was its steepest monthly fall since March 2025, the outlet reported.
Information technology represented 38.40% of the S&P 500 on Oct. 29, according to State Street. S&P Dow Jones Indices says company weights are based on market value adjusted for shares available to public investors. The technology sector’s combined weight helps explain how its losses can affect the benchmark even when many other stocks rise.
IG’s figures for the four-week period ending Oct. 30 put the equal-weighted S&P 500 up 4.4% and the standard benchmark down 1.1%. That rolling window is separate from calendar-month performance.
The final U.S. trading session of October brought steeper declines: on Oct. 30, the S&P 500 fell 1.8%, the Nasdaq Composite lost 2.9% and the Dow Jones Industrial Average dropped 572 points, or 1.1%. Intel shares fell 28.6% that day.
Amazon reported a 12-month free cash flow deficit of $42.4 billion through Sept. 30. It said purchases of property and equipment accounted for most of the cash use after rising $94.8 billion from a year earlier, largely reflecting AI investment. The company projected about $220 billion in cash capital expenditures for 2026. AWS sales rose 39% year over year to $46 billion in the quarter ended Sept. 30.
Alphabet reported that Google Cloud revenue grew 103% to $30.7 billion in the same quarter. Its filing put quarterly capital expenditures at $51.4 billion, with technical infrastructure accounting for most of the investment.
