Four names dominated the premarket ticker board: IBM, Walmart, Rocket Lab, and Nvidia. Each moved for entirely different reasons, but together they paint a useful picture of where investor attention, and anxiety, is concentrated right now.

Look, premarket moves don’t always stick. But when the biggest movers span AI chips, retail giants, cloud infrastructure, and literal rocket science, it’s worth paying attention to the signals underneath.

Nvidia keeps doing Nvidia things

Nvidia continues to be the stock that makes other CEOs question their life choices. The chipmaker reported quarterly sales growth of 62% year-on-year, a number that would be impressive for a startup and is frankly absurd for a company of Nvidia’s size.

The company guided for $65B in revenue for the January quarter. Shares climbed 4.8% in premarket trading on the back of that forecast, because apparently growing at 62% wasn’t enough to move the needle without forward guidance to match.
