Nvidia Corp. (NVDA) lost nearly $450 billion in market value on Thursday, and CNBC's Jim Cramer said the artificial intelligence darling should buy its own stock.

'Buy and Reload'

In a post on X, Cramer said a company should buy its own stock when it is the cheapest asset around.

"Nvidia can buy and reload... or they can let it go down," he added.

If the cheapest asset is your stock, you should buy it. Nvidia can buy and reload... or they can let it go down

The company is now about 25% below its Oct. 6 record high of 243.37, having lost $1.39 trillion in market value, including $446.94 billion in Thursday's session.

In a separate post, Cramer, who has long backed the stock, said he had "waited" for Nvidia to open lower. It had been up almost every day, he said, and "has made people heartsick who bought it."

NVDA finally opens DOWN, i have waited for that... it's been up almost every day and has made people heartsick who bought it

Nvidia Leads a Data Center Selloff

The Nasdaq Composite had its biggest one-day drop since the 2020 pandemic Thursday, two days after the midterm elections, and the S&P 500 lost about $3 trillion.

Fears of limits on data centers added to the selling. Citi Research data shared by The Information shows U.S. data center bans and pauses topped 500 by October, from near zero through mid-2025.

In Texas, Gov.-elect Gina Hinojosa, a Democrat, defeated Gov. Greg Abbott after pledging a moratorium on all data center approvals until lawmakers pass protections.

Sen. Bernie Sanders (I-Vt.) renewed his call for a national moratorium, and Rep. Yassamin Ansari (D-Ariz.) urged Democrats to push a "ban on artificial superintelligence."

Congress Asks Huang to Brief Lawmakers

On Thursday, three House chairs asked Nvidia CEO Jensen Huang for a closed-door briefing on Nov. 18 about his interactions with Alice Huang, a Megaspeed executive the chairs described as a publicly reported Chinese intelligence asset.

The New York Times reported last week that U.S. officials determined Alice Huang, also known as Huang Le, was a Chinese intelligence asset who allegedly passed information to Beijing while close to Jensen Huang.

Price Action: On Thursday, Nvidia's shares closed 9.26% lower at $181.60 and climbed 1.93% to $185.10 in overnight trading.

The stock has fallen 2.40% so far this year and 6.75% over the past year.

Market data rankings indicate Nvidia's stock has a Momentum score in the 35th percentile and a Value score in the 8th percentile.
