NVIDIA (NASDAQ: NVDA) is still the most important stock after two-plus years of dominating the stock market. Its GPU technology unlocked the door to AI, and now NVIDIA is capitalizing on it using a full-stack method.

Nvidia traded slightly higher after Jensen Huang's CES keynote. Traders are eyeing key economic data later in the week.

U.S. equity futures edged higher in early Tuesday trading, while Treasury yields steadied and the dollar slipped, as investors looked to the first of a series of job market data releases that could test the market's early January rally.
