Stock futures were mostly down on Wednesday as Wall Street waited for the Federal Reserve’s preferred inflation gauge, the final major economic data due before the Thanksgiving holiday. Futures tracking the Dow Jones Industrial Average edged up 25 points, or 0.1%, while contracts tied to the S&P 500 were down 0.1%. Both the S&P 500 and Dow had closed at record levels on Tuesday, as investors shrugged off President-elect Donald Trump’s tariff threats.
