Wall Street ends modestly lower after careening from a small gain to as much as 10% below its record

NEW YORK (AP) - Wall Street ended lower after careening from a small gain to 10% below its record. The whipsaw trading followed the latest escalation in President Donald Trump's trade war. The S&P 500 fell 0.8% Tuesday, after falling as much as 1.5%. The Dow Jones Industrial Average fell 478 points, or 1.1%. The Nasdaq composite slipped 0.2%. Gains for Tesla and other influential stocks muted the losses. Trump said he would double his planned tariffs on steel and aluminum for Canada, a retaliation that prompted the provincial government of Ontario to back down on its planned surcharges on electricity sold to the U.S.

THIS IS A BREAKING NEWS UPDATE. AP's earlier story follows below.

NEW YORK (AP) - A manic day on Wall Street is sending the U.S. stock market careening, from a slight morning gain to a 10% drop from its record set last month and back again, following President Donald Trump's latest escalation in his trade war.

Such head-spinning moves are becoming routine following a scary ride for investors where the S&P 500 has swung by at least 1%, up or down, seven times in the last eight days. The heaves back and forth are a result of Wall Street's uncertainty about how much pain Trump is willing for the economy to endure through tariffs and other policies in order to remake the country and world in Trump's fashion.

And moves by Trump and comments by his White House on Tuesday didn’t clarify much.

The S&P 500 was up 0.2% in late trading, but that was only after zooming between an early gain of 0.2% and a later tumble of 1.5%. At its bottom for the day, the index was more than 10% below its all-time high and on track for what Wall Street calls a "correction."

The Dow Jones Industrial Average was down 172 points, or 0.4%, as of 2:55 p.m. Eastern time. While the majority of U.S. stocks were falling, gains for Tesla and a handful of other highly influential stocks were muting the effect, and the Nasdaq composite was 1.1% higher.

Stocks began tumbling in the morning after Trump said he would double planned tariff increases on steel and aluminum coming from Canada. The president said it was a response to moves a Canadian province made after Trump began threatening tariffs on one of the United States' most important trading partners.

Trump has acknowledged the economy could feel some "disturbance" because of the tariffs he’s pushing. Asked on Tuesday just how much pain Trump would be willing for the economy and stock market to take, when the market was nearing its lows, White House press secretary Karoline Leavitt declined to give an exact answer. But she said earlier in a press briefing that "the president will look out for Wall Street and for Main Street."

For his part, Trump said earlier on social media, "The only thing that makes sense is for Canada to become our cherished Fifty First State. This would make all Tariffs, and everything else, totally disappear."

Tuesday’s swings for the stock market followed more warning signals flashing about the economy as Trump's on -and- off -again rollout of tariffs creates confusion and pessimism for U.S. households and businesses.

Such tariffs can hurt the economy directly by raising prices for U.S. consumers and gumming up global trade. But even if they end up being milder than feared, all the whipsaw moves could create so much uncertainty that U.S. companies and consumers freeze, which would sap energy from the economy.

Delta Air Lines said late Monday that it's already seeing a change in confidence among customers, which is affecting demand for close-in bookings for its flights. That pushed the airline to roughly halve its forecast for revenue growth in the first three months of 2025, down to a range of 3% to 4% from a range of 7% to 9%.

Delta's stock lost 6.1%.

Southwest Airlines also cut its forecast for an important underlying revenue trend, and it pointed specifically to less government travel, among other reasons, including wildfires in California and "softness in bookings and demand trends as the macro environment has weakened."

Its stock nevertheless rallied 8.5%, though, after the airline said it would soon begin charging some passengers to check bags and announced changes to encourage its most loyal customers.

Oracle dropped 2.9% after the technology giant reported profit and revenue for the latest quarter that fell short of analysts' expectations.

Helping to keep the market in check despite all such worries were several Big Tech stocks, which steadied a bit after getting walloped in recent months. Elon Musk's Tesla rose 5.7%, for example, after Trump said he would buy a Tesla in a show of support for "Elon's 'baby.'"

Tesla’s sales and brand have been under pressure as Musk has led efforts in Washington to cut spending by the federal government. Tesla’s stock is down 41.8% for the young year so far.

Other Big Tech superstars, which had led the market to record after record in recent years, also held a bit firmer. Nvidia added 4.1% to trim its loss for the year so far to 17%. It's struggled as the market's sell-off has particularly hit stocks seen as getting too expensive in Wall Street's frenzy around artificial-intelligence technology.

Because Nvidia, Tesla and other Big Tech stocks have grown so massive in size, the movements for them carry much more weight on the S&P 500 and other indexes than any other company, by far. If not for Nvidia alone, the S&P 500 would be down for Tuesday.

In stock markets abroad, which have mostly been beating the United States so far this year, indexes fell across much of Europe and Asia.

Stocks rose 0.4% in Shanghai and were nearly unchanged in Hong Kong as China's annual national congress wrapped up its annual session with some measures to help boost the slowing economy.

In the bond market, Treasury yields held a bit steadier after tumbling in recent months on worries about the U.S. economy. The yield on the 10-year Treasury rose to 4.28% from 4.22% late Monday. In January, it was nearing 4.80%.

A report released Tuesday morning showed that U.S. employers were advertising 7.7 million job openings at the end of January, exactly as economists expected. It’s the latest signal that the U.S. job market remains relatively solid overall, for now at least, after the economy closed last year running at a healthy pace. _
