Stock futures flat as investors await Nvidia earnings and inflation data

U.S. stock futures were flat Monday evening as investors turned cautious ahead of Nvidia's earnings and a key inflation report due later this week. The S&P 500 had fallen 0.28% in regular trading, while the Dow gained 0.26%. Nvidia's quarterly report is due Wednesday after the closing bell, and the personal consumption expenditure price index for July is also out Wednesday. Treasury yields fell after a CNBC report that the Treasury Department could use its $1 trillion General Account to fund government bond purchases. Federal Reserve Chairman Kevin Warsh is expected to speak Friday at the Jackson Hole symposium. Wells Fargo strategists said the week's events could accelerate market volatility but view any pullback as a buying opportunity, citing record corporate earnings driven by AI capital spending.
