Key Takeaways AI stocks had a volatile week as Wall Street reckoned with the implications of a sophisticated, cost-efficient AI model from Chinese start-up DeepSeek.Semiconductor stocks such as Nvidia and Broadcom sold off on Monday as investors worried DeepSeek's efficiencies would temper enthusiasm for AI infrastructure spending.

"In our view this is a correction and not the start of a sustained bear market," Goldman Sachs said. DeepSeek sparked a $1 trillion market rout on Monday.
