Wall Street’s main indexes climbed on Monday, as investors attempted to shake off last week’s AI anxieties while awaiting more clarity on the controversy surrounding Nvidia CEO Jensen Huang.

The gains kick off a pivotal week expected to offer some insight into whether the selloff post the midterms last week went too far or was warranted. Analysts warned that several concerns were converging under the surface.

Shares of Nvidia, the second most valuable company in the world, fell 5.6% after an internal investigation into whether CEO Huang had been targeted by a foreign intelligence effort raised questions about his future at the AI chipmaker.

“This was just the cherry on top for investors looking to pull out of AI-linked stocks. It’s a very bad headline that’s affecting tech stocks,” said Nadia El Bilassy, senior market analyst at Equiti Group.

The focus on Nvidia may subside later this week “when we have more important things to discuss, like the inflation data,” she added.

The Labor Department is scheduled to release its Consumer Price Index report for October on Tuesday, with economists polled by Reuters expecting a 2.7% increase year-over-year.

Fears of a December rate hike also persisted following October’s stronger-than-expected jobs data.

At 09:46 a.m. ET, the Dow Jones Industrial Average rose 652.49 points, or 1.27%, to 51,938.22, the S&P 500 gained 108.81 points, or 1.48%, to 7,485.67 and the Nasdaq Composite gained 458.92 points, or 1.87%, to 25,038.34.

Nine of 11 major S&P 500 sectors were in positive territory, with consumer discretionary and communication services leading gains.

Wall Street brokerages including Morgan Stanley and UBS called last week’s rout in the AI trade overdone, arguing that the risks of extreme regulation of data center developments under a Democrat-controlled Congress are unlikely to play out.
