U.S. stock futures were flat Friday as investors grappled with ongoing tariff uncertainty and awaited the release of a key inflation measure.

Dow Jones Industrial Average futures slipped 19 points, or 0.04%. S&P 500 futures dipped 0.1%, and Nasdaq 100 futures traded 0.2% lower.

February’s personal consumption expenditures price index is due at 8:30 a.m. ET and could confirm whether investors should be concerned about sticky inflation, especially after the Federal Reserve recently raised its inflation forecast. Economists polled by Dow Jones see the headline PCE price index reading rising 0.3% in February and 2.5% from 12 months earlier.

The report comes after a losing session for the major averages. On Thursday, the 30-stock Dow fell about 155 points, or 0.4%. The S&P 500 slid 0.3%, while the Nasdaq Composite dropped 0.5%.

Those moves took place after President Donald Trump announced a 25% tariff on “all cars that are not made in the United States,” the latest tariff development to roil the market. Investors — concerned that rising signs of weakening consumer sentiment are heightening the risk of a slowdown — are hoping April 2 will bring some much-needed clarity.

“I don’t expect that market volatility is going to calm until we have more policy [certainty]. And a lot of us are looking to see if we get that next week,” New York Life Investments’ chief market strategist Lauren Goodwin said on CNBC on Thursday. “I’m not really seeing it. I anticipate that this volatility is here to stay with us.”

As of Thursday’s close, Wall Street was headed for a second straight week of gains. The Dow is on track for a 0.8% advance week to date. The S&P 500 is up 0.5% for the period, while the Nasdaq Composite is on pace for a 0.1% gain.
