The S&P 500 was up 3.7% in morning trading, though it still remains more than 14% below its record set in February. The Dow Jones Industrial Average was up 1,363 points, or 3.6%, as of 10:12 a.m. Eastern time, and the Nasdaq composite was 4.2% higher.

The bounce was global. Stock indexes rose 6% in Tokyo, 3.4% in Paris and 1.6% in Shanghai. The price of crude oil also pulled a bit higher after touching its lowest level since 2021 on Monday.

Bitcoin steadied and was back above $79,000 after dropping toward $76,000 the prior day. No big change is behind the move back upward, and analysts say more swings up and down are likely for markets in not only the days but also the hours ahead.

The big question remains centered on how long Trump will keep his stiff tariffs on other countries, which would raise prices for U.S. shoppers and slow the economy. If they last a long time, economists and investors expect it to cause a recession. But if Trump lowers them through negotiations relatively quickly, the worst-case scenario can be avoided.

Hope still remains on Wall Street that negotiations may be possible, and Trump said Monday that he reached the “confines and probability of a great DEAL for both countries” after talking with South Korea’s acting president.

“Their top TEAM is on a plane heading to the U.S., and things are looking good,” Trump said on social media. “We are likewise dealing with many other countries, all of whom want to make a deal with the United States.”

Japanese stocks led global markets after the country’s prime minister, Shigeru Ishiba, appointed his trade negotiator for talks with the United States. It was based on an agreement between Ishiba and Trump, Japanese officials said.

Of course, other countries are taking a more aggressive tack. China said it will “fight to the end” and warned of countermeasures after Trump threatened on Monday to raise his tariffs even further on the world’s second-largest economy.

But such a bounce back for global markets on Tuesday perhaps shouldn’t be a surprise. Stocks don’t go in one direction forever, and some of the best days in the market’s history have been clustered around some of its worst days.

The biggest gain for the S&P 500 since World War II was an 11.6% surge on Oct. 13, 2008, for example. That was during the depths of the Great Recession, when worries were high that the financial system was collapsing and the S&P 500 was in the midst of a nearly 57% plunge from its peak in late 2007 until its bottom in March 2009. A couple weeks later, the index had another one of its best days in history, soaring 10.8%.

That’s one of the reasons many financial advisers suggest not trying to time the market and selling stocks and other investments meant for the long term when nervous, because of the risk of missing out on such huge up days.

Some more Republican voices are criticizing the White House’s rollout of tariffs, which could sway Trump’s thinking. Sen. John Kennedy, a Louisiana Republican, said he supports the president’s goals of better trade deals but worries about the economic uncertainty, for example.

“We don’t know if the medicine will be worse than the disease,” Kennedy said, adding, “This is President Trump’s economy now.”

That follows mixed messages from Trump on Monday. He said he was open to negotiations “if we can make a really fair deal and a good deal for the United States.” Trump also added that it’s possible to have both negotiated settlements with other countries and permanent tariffs.

Trump’s trade war is an attack on the globalization that’s shaped the global economy and helped bring down prices but also caused manufacturing jobs to leave for other countries. He has said he wants to bring factory jobs back to the United States, a process that could take years. Trump also says he wants to narrow trade deficits with other countries.

On Wall Street, health insurers helped lead the market after the Centers for Medicare & Medicaid Services announced a stronger-than-expected increase in Medicare Advantage payments for next year. Humana jumped 12.5%, United Health climbed 7.8% and Elevance rose 5.2%.

Levi Strauss rose 2.8% after reporting profit for the latest quarter that topped analysts’ expectations. It also gave a strong forecast for 2025 despite the ongoing trade war and tariff threats.

In the bond market, Treasury yields rallied for a second straight day to recover more of their sharp losses from prior months. The yield on the 10-year Treasury rose to 4.24% from 4.15% late Monday and from just 4.01% late Friday.

Yields tend to rise with expectations for the U.S. economy’s strength and for inflation. ___ AP Business Writers Matt Ott and Elaine Kurtenbach contributed.
