Stock index futures were close to the flatline Thursday with tariff moves continuing to dominate Wall Street in a week with few major economic indicators or earnings. S&P futures (SPX) and Nasdaq 100 futures (US100:IND) were little changed.

Wall Street looked to keep momentum from a tech-fueled rally that saw Nvidia leap to become the world's first $4 trillion public company.

US Stock futures slipped early Thursday after the S&P 500 recouped some of its losses from this week's tariff-fueled slide. S&P 500 futures traded 0.25% lower, while the Nasdaq 100 futures dropped 0.29%.
