NEW YORK — Back down goes Wall Street, and its former superstars are once again leading the way on Tuesday.

The S&P 500 is down 1.3% in midday trading. It’s the latest swerve in a scary ride where it tumbled by 10% from its record and then rallied for two straight days. The Dow Jones Industrial Average was down 325 points, or 0.8%., as of 11 a.m. Eastern time, and the Nasdaq composite was 2.1% lower.

Tesla was one of the heaviest weights on the market after falling 6.1%. The electric-vehicle maker’s stock has been struggling on worries that it will lose sales because of anger at its CEO, Elon Musk, who has been leading efforts to cut spending by the U.S. government. EV rivals, meanwhile, continue to chip away at its business. China’s BYD on Monday announced an ultra-fast charging system that it says is nearly as quick as a gasoline fill-up.

Alphabet sank 3.8% after the owner of Google said it would buy cybersecurity firm Wiz for $32 billion. It would be the company’s most expensive purchase in its 25-year history, and it could boost the tech giant’s in-house cloud computing amid burgeoning artificial-intelligence growth.

The drop for Big Tech continues a trend that’s taken hold in the market’s recent sell-off: Stocks whose momentum had earlier seemed unstoppable have since dropped sharply following criticism that they had simply grown too expensive.

Chief among them have been stocks that zoomed higher in the frenzy around AI technology. Nvidia fell 3.2%. Super Micro Computer, which makes servers, lost 4.4%. Palantir Technologies, which offers an AI platform for customers, sank 4.9%.

These stocks have been among the biggest losers as Wall Street retrenches amid uncertainty about what President Donald Trump’s trade war will do to the economy. Trump’s rat -a- tat announcements on tariffs and other policies have created worries that U.S. households and businesses could hold back on their spending, which would hurt the economy.

It all makes the calculus different for the Federal Reserve, which is beginning its latest meeting on interest-rate policy and will make its announcement on Wednesday.

The Fed could lower its main interest rate, which would make it easier for U.S. businesses and households to borrow. That in turn could boost the economy. But lower interest rates can also push inflation upward, and U.S. consumers have already begun bracing for higher inflation because of tariffs.

Virtually everyone on Wall Street expects the Fed to hold its main interest rate steady on Wednesday, as it waits for clues about how the uncertainty will play out. The job market, for the moment at least, appears relatively stable after the economy closed last year running at a solid rate.

More attention will be on the forecasts the Fed will publish after the meeting, showing where officials expect interest rates, inflation and the economy to head in upcoming years. For now, traders on Wall Street are largely expecting the Fed to deliver two or three cuts to rates through the end of this year.

One of the reasons the U.S. stock market’s sell-off in recent weeks has “so far been orderly,” with the epicenter remaining within tech, may be because of faith that the Fed can protect Wall Street, according to strategists at Barclays. If conditions were to deteriorate quickly, the Fed could cut rates to support the economy.

Such faith “crucially could be put to test this week” if the Fed appears to be more concerned about inflation than a weakening economy, at least relative to the market’s expectations, according to the Barclays strategists led by Venu Krishna.

In stock markets abroad, indexes rose across much of Europe and Asia. They have broadly been doing better than the U.S. stock market this year, flipping a yearslong trend and forcing questions about whether the end has arrived for what was called “U.S. exceptionalism.”

Japan’s Nikkei 225 rose 1.2%. Investors expect the Bank of Japan to keep its benchmark interest rate unchanged at a monetary policy board meeting due to wrap up Wednesday.

Trading on Indonesia’s stock exchange was suspended temporarily as the benchmark JSX tumbled as much as 6%. But it later pared the loss to 3.8%.

Investors have been sending shares of state-owned banks lower after the government launched a sovereign wealth fund, called Danantara, that so far has not proven popular. Worries over U.S. tariffs and other risks have also shaken confidence in the economy of the world’s fourth-most populous nation, said Budi Frensidy, a professor at the University of Indonesia.

In the bond market, the yield on the 10-year U.S. Treasury note edged down to 4.30% from 4.31% late Monday.
