U.S. stock futures showed little movement as traders await the Federal Reserve's preferred inflation gauge, with Dow futures up 20 points and S&P 500 futures slightly higher, while Nasdaq-100 futures dipped. Dell Technologies fell 10% after a disappointing revenue forecast, and HP and Workday also reported weaker-than-expected earnings guidance, causing their stocks to slide. Key inflation data, including the personal consumption expenditures price index, personal income, and consumer spending, will be released on Wednesday, influencing the Fed's upcoming rate policy decisions.
