US stocks opened mixed on Thursday as Nvidia's (NVDA) stellar earnings failed to impress investors despite beating revenue and profit expectations. The Dow Jones Industrial Average (^DJI) climbed 0.4% while the S&P 500 (^GSPC) and Nasdaq Composite (^IXIC) slipped 0.2% and 0.4%, respectively. Nvidia shares fell over 3% after the chip giant reported $68.1 billion in fourth-quarter revenue, up 73% from a year ago.

Investors expressed disappointment with Nvidia's outlook, particularly the lack of detail on growth drivers and the exclusion of potential China revenue from guidance. While the company projected first-quarter revenue of $78 billion, some analysts had expected figures approaching $80 billion. The lukewarm response reflects growing concerns about AI's staying power and competitive threats in the semiconductor sector.

Elsewhere, Stellantis (STLA) posted a massive $26.3 billion full-year loss after an EV-related charge, though improving second-half results suggest CEO Antonio Filosa's turnaround efforts may be gaining traction. Nutanix (NTNX) shares surged over 15% after strong earnings and a new multiyear partnership with AMD, which will invest $250 million in the cloud computing provider. The market continues to grapple with AI-driven volatility and awaits January wholesale inflation data that could influence Federal Reserve interest rate decisions.
