The US stock market slips as Nvidia and AI superstars keep swinging

Nvidia was the heaviest weight on the market after the chip company lost 2.7%. Other AI darlings also struggled, including drops of 3.4% for Palantir Technologies and 4.2% for Super Micro Computer.

Questions have been rising worldwide about whether such superstar stocks can add more to their already spectacular gains. Palantir earlier this month had a stunning rise of nearly 174% for the year so far, for example.

Such sensational performances have been one of the top reasons the U.S. market has hit records despite a slowing job market and high inflation. AI stock prices have shot so high, though, that they’ve drawn comparisons to the 2000 dot-com bubble which ultimately dragged the S&P 500 down by nearly half after bursting.

In the meantime, Wall Street is waiting to see if more news coming about the economy’s health will be good news or bad.

The U.S. government is reopening following a six-week shutdown, its longest in history. The stock market mostly rose through the shutdown, as it has often done historically, but Wall Street is bracing for potential swings as the government gets back to releasing important updates on the job market and other signals about the economy’s strength.

The fear is that the data could persuade the Federal Reserve to halt its cuts to interest rates, which can boost the economy but also worsen inflation. Wall Street has already run to records in part on expectations for more such cuts, and a pullback could hurt the stock market.

The “looming data deluge may spur additional volatility in the coming weeks,” according to Doug Beath, global equity strategist at Wells Fargo Investment Institute.

Traders have already reduced their bets that the Fed will cut its main interest rate at its next meeting in December, now seeing a 53% of that, down from nearly 70% a week ago, according to data from CME Group.

That helped push yields higher in the bond market, which can weigh on prices for stocks and other investments.

The yield on the 10-year Treasury rose to 4.10% from 4.08% late Wednesday.

On Wall Street, The Walt Disney Co. helped lead the market lower after falling 8.2%. The entertainment giant reported profit for the latest quarter that topped analysts’ expectations, but its revenue fell short.

That helped offset a jump of 4.3% for Cisco after the tech giant delivered profit and revenue that were bigger than analysts estimated.

In stock markets abroad, indexes were mixed in Europe following modest gains in Asia.

Japan’s Nikkei 225 index rose 0.4%, even as tech giant SoftBank Group lost another 3.4%. It’s been struggling since it said it had sold all of its investments in Nvidia.
