Nvidia Shares Roar Back as Clouds Hanging Over Chipmaker Fade

After several months in the wilderness, NVIDIA shares have found their way again as doubts about Big Tech spending subside, trade tensions with China ease, and new chip buyers emerge. Shares of Nvidia rose 16% this week

The stock rallied this week and is on track for the best month in a year after a series of long-term sales agreements during President Donald Trump’s trip to the Middle East. That followed a tariff detente between the US and China and an earnings season that showed Nvidia’s biggest customers remain full-steam ahead on capital spending related to artificial intelligence infrastructure, where the chipmaker dominates.

The stock has now advanced around 44% from an April low and is less than 6% from where it closed on Jan. 24, the day before the emergence of DeepSeek’s R1 model sparked fears that cheaper AI development would hurt sales, sending Nvidia and other technology stocks tumbling.
