U.S. stock futures were mixed on Oct. 1, with Dow futures down 0.52%, S&P 500 futures almost flat and Nasdaq 100 futures up 0.29%. Treasury yields climbed to multi-decade highs as investors weighed persistent inflation, rising government debt and higher energy costs linked to the Middle East conflict. Ten-year Treasury yields reached 5.32% and 30-year yields 5.66%, their highest levels since 2002, after benchmark Treasuries recorded their worst quarter since 1994. Micron Technology’s forecast for quarterly revenue above market expectations and increased customer commitments under supply agreements to $32 billion supported sentiment around artificial-intelligence-related stocks, although its shares fell about 1% in premarket trading after more than tripling this year. Lam Research and Applied Materials each rose 1.8%, while Nvidia and Advanced Micro Devices gained about 1%. Alphabet advanced 2.3% after announcing its Gemini 4 flagship AI model. The VIX volatility index (Wall Street’s fear gauge) reached a two-week high and was last at 16.84 points. Softer-than-expected inflation data reduced expectations for an interest-rate increase later this month, with traders pricing a 63% chance of the Federal Reserve holding rates, according to CME Group’s FedWatch Tool. Because inflation remains above the central bank’s 2% target, a December rate increase remains possible. Markets were also set to assess comments from Thomas Barkin, Christopher Waller, Philip Jefferson, Michelle Bowman and Lorie Logan, along with weekly jobless claims and the Institute for Supply Management’s manufacturing indicator.
