US stock indices declined for a second consecutive session on Friday as a batch of economic data underscored a challenging environment for corporate America. The three major averages fell by as much as 0.5%. Annualized US GDP growth slowed to 1.4% in Q4, sharply undershooting expectations for a 3% expansion and casting doubt on the narrative that the economy remained resilient in the face of tariffs and the government shutdown. Equities also came under pressure from a jump in the PCE price index and a stronger-than-expected reading in the core measure, dampening hopes for a more accommodative Federal Reserve stance after policymakers reiterated that persistent inflation remains a key factor in rate decisions. High-profile AI-related names retreated, with Nvidia, Meta, and Microsoft losing up to 1%. Banks and asset managers extended their declines amid a weaker credit outlook. Meanwhile, Newmont traded slightly below the flatline after projecting lower gold output for the year.
