Markets hold near flat as GDP, PCE data and tariff ruling loom

U.S. stock futures were mixed Friday ahead of Q4 GDP data and the Fed's preferred inflation gauge (PCE), plus a Supreme Court ruling on Trump's tariffs; Dow futures fell about 30 points, S&P 500 futures were little changed, and Nasdaq-100 futures rose ~0.1%. Economists expect Q4 real GDP growth around 2.5% and the PCE price index about 2.8% year over year (core ~3%). Fed minutes show officials split on rate cuts, signaling more evidence inflation must cool. A ruling against tariffs could lift markets, though the White House may reimpose duties later. In recent sessions, the Dow and Nasdaq slipped while oil rose amid U.S.–Iran tensions; Nvidia earnings are due next week.
