U.S. stock futures were rising early Wednesday after indexes reached new highs on the back of encouraging inflation data, firming up bets on a September rate cut from the Federal Reserve. Dow Jones Industrial Average futures were up 97n points, or 0.2%. The S&P 500 and Nasdaq Composite indexes hit record highs on Tuesday following consumer price index data showing core prices rising 3.1% over the past 12 months but lower-than-feared goods inflation, suggesting a limited inflationary effect from tariffs.
