The Dow Jones Industrial Average tumbled for a second day as President Donald Trump's tariffs left investors fearful of potential shockwaves for the economy.

The blue-chip average dropped 670.25 points, or 1.55%, building on Monday's plunge of nearly 650 points. The Dow ended the session at 42,520.99. The S&P 500 dropped 1.22% and closed at 5,778.15 after notching its worst day of the year in the prior session. The Nasdaq Composite lost 0.35% and finished at 18,285.16.

At their worst levels, the Dow fell more than 840 points and the S&P 500 slid 2%. The Nasdaq had dropped more than 2% at its lowest and at points flirted with correction territory, a term that refers to an index falling 10% from a recent high. More than 4 out of 5 S&P 500 stocks ended the day lower. Some investors scooped up shares like Nvidia that have been battered this year.

Tuesday's drop came after Trump instituted 25% duties on Canada and Mexico that took effect at midnight. He also slapped an additional 10% tariff on Chinese goods. China retaliated with additional tariffs of up to 15% on some U.S. products, while Mexican President Claudia Sheinbaum said the U.S.' southern neighbor would respond with tariffs and other measures that would be announced this weekend.

After Canadian Prime Minister Justin Trudeau said his country would also put a 25% levy on U.S. goods, Trump said in response that he would add even higher tariffs on the country.

Shares of companies with significant imports came under pressure. Shares of GM and Ford dropped more than 4% and nearly 3%, respectively. Chipotle, which sources about half of its avocados from Mexico, slipped 2%. Target shed 3% with its CEO saying prices for some produce would be going higher in the next few days because of the tariffs.

This week's decline pushed the S&P 500 into the red for 2025 and brought the Dow to the flatline on the year. Because investors hoped that a last-minute deal could be reached to sidestep the full taxes on Mexico and Canada, losses steepened in Monday's session after Trump confirmed the long-awaited levies were coming.

"I'm calling it a conditional correction," said Sam Stovall, chief investment strategist at CFRA Research. "It's really based on one condition: By how much Trump is going to retain the tariffs."

Paired with soft economic data released recently, the tariffs have given market participants further reason for worry about the health of the U.S. economy. Bank and retail stocks led the way down on Tuesday as investors feared that the levies could lead to another hit on economic growth.

With Tuesday's losses, the S&P 500 now trades below where it finished on Election Day in November, when Trump won his second term in office. Traders will closely monitor Trump's address to Congress on Tuesday night for statements about the tariffs, which were a core pillar of his campaign.

Stocks close lower

The three major indexes finished Tuesday's session in the red.

The Dow and S&P 500 slid 1.6% and 1.2%, respectively. The Nasdaq Composite pulled back nearly 0.4%.

Some of the market's biggest losers pare back their losses

Among the stocks clawing back their losses from earlier in Tuesday's session were the day's biggest losers.

Tuesday afternoon saw notable bounceback activity, with Monday's worst-performing decile of S&P 500 stocks trading an average of 4.5% from their intraday lows on Tuesdays.

Shares of Super Micro Computer, for instance, opened Tuesday in negative territory after sliding 13% on Monday. Shares were last trading 10% higher, while during their lows of the day they were over 4% in the red.

Likewise, AI darling Nvidia was nearly 4% lower earlier in the day but was last up nearly 4% and trading at its session highs. Palantir was down around 5% by mid-morning but was last up 4% on the day.

Enphase Energy also had one of the biggest upside swings and was earlier down more than 4%. The solar stock was last trading more than 10% higher.

Stocks well off lows as final trading hour kicks off

Stocks regained much lost ground in afternoon trading.

The Dow and S&P 500 were down just 0.6% and 0.2%, respectively, shortly after 3 p.m. ET. Both dropped around 2% at session lows.

The Nasdaq Composite rallied 0.9%, a notable swing after tumbling more than 2% at its worst point in the trading day.

Best Buy on track for worst day since 2020

Best Buy shares fell more than 12% in early afternoon trading on Tuesday, a move lower that put the stock on pace for its worst day in nearly five years.

If the stock were to close around this level, it would see its largest percentage decrease in a single day since March 12, 2020, when it fell 15.3%.

The decline comes on the heels of the company's chief executive, Corie Barry, warning on an earnings call with analysts that U.S. President Donald Trump's 25% tariff on goods from Mexico and additional 10% tariff on goods from China could lead to higher prices for consumers. For the fourth quarter, the retailer's earnings and revenue topped Wall Street estimates.

"We expect our vendors across our entire assortment will pass along some level of tariff costs to retailers, making price increases for American consumers highly likely," the CEO said during the call.

Look toward defensive sectors, says Morgan Stanley Wealth Management

Monica Guerra, head of U.S. policy at Morgan Stanley Wealth Management, advises looking toward safe assets and defensive sectors amid the heightened uncertainty from President Donald Trump's trade war.

"The markets today are emblematic of where to go, and that's to consider more safe assets, staying in defensives — you're looking at utilities, real estate — very low exposure to tariffs," she said during a keynote address at a conference for the National Association for Business Economics.

Tariffs will present a drag on growth and present inflation risks, she added.

"This is a multifaceted policy, and I think that markets are considering all the potential options," Guerra added.

Nasdaq mitigates losses

The Nasdaq Composite was able to see smaller losses than the other two major averages in Tuesday's session as some tech names notched notable gains.

Nvidia and Alphabet each gained more than 2%. Outside of megacap tech, Super Micro Computer popped nearly 10%.

To be sure, not all tech names were rising and the index was still down about 0.3% in afternoon trading. Notably, Meta Platforms and Tesla slid more than 3% and 4%, respectively.

Financial stocks head for worst session since regional banking crisis

Financial stocks in the S&P 500 on Tuesday were poised to notch their biggest one-day loss since 2023's regional banking crisis.

The sector tumbled 3.8% in late morning trading, making it the worst performer of the 11 that comprise the broad index. If that holds through session close, it would mark the sector's worst day since March 9, 2023. That was during the week that Silicon Valley Bank collapsed, which sparked a panic among investors in regional banks.

KKR and Citigroup led the sector down with declines of more than 9% and 8%, respectively. Bank of America followed with a drop of nearly 7.5%.

Both the SPDR S&P Regional Banking ETF (KRE) and SPDR S&P Banking ETF (KBE) slid more than 4% in Tuesday's session.

Consumer staples sector stays afloat amid sell-off, buoyed by Walgreens

The S&P 500 Consumer Staples sector is one of the few bright spots during Tuesday's continued downturn, hovering just above flat while the remaining 10 sectors traded in the red and the broader market sank more than 1.5%.

Boosting the sector is Walgreens, which popped 6.3% on news that the drugstore chain is nearing a deal with private equity firm Sycamore Partners to be taken private for roughly $10 billion. The parties are aiming to complete the deal as soon as Thursday, according to a Wall Street Journal report.

Food companies General Mills, Hershey, Mondelez and PepsiCo each jumped more than 2%. Household and consumer products makers Procter & Gamble and Colgate-Palmolive also each traded roughly 2% higher.

Trump falsely claims U.S. banks cannot do business in Canada

President Trump on Tuesday falsely claimed that U.S. banks are not able to do business in Canada after the U.S. issued a 25% tariff on imports from that country.

"Canada doesn't allow American Banks to do business in Canada, but their banks flood the American Market. Oh, that seems fair to me, doesn't it?" the president wrote on Truth Social.

While Canada's banking sector is tightly regulated, American banks are allowed to operate there.

Money center banks all suffer corrections in early trading Tuesday

The four largest lenders in the U.S., also known as the money center banks, suffered sharp losses Tuesday.

Citigroup tumbled as much as 8%, Wells Fargo dropped as much as 6.8%, Bank of America slumped 6.5% and JPMorgan retreated 5.2%.

All four have now fallen more than 10% from their recent 52-week highs, meaning the stocks are now in a correction, according to conventional wisdom on Wall Street. Declines of 20% or more are regarded as marking a bear market.

At Tuesday's lows, Citigroup was down about 18.3% from its mid-February 52-week high, Wells Fargo was off 12.1% from its early February high, and Bank of America had fallen 11.9% and JPMorgan 11.8% from their recent highs.

BTIG: S&P 500 is headed for seventh straight loss, semis are reaching multiyear relative lows

Stocks are consistently selling off as Tuesday's trading session begins. And semiconductor stocks — which have been the market's darling over the past year — are breaking out to near multiyear relative lows, according to BTIG chief market technician Jonathan Krinsky.

"Barring another late day reversal like we saw on Friday, today will be the seventh day in the last eight sessions where SPX closed below its open. The slope of the SPX's 50 DMA has now inflected lower, another sign of medium-term trend deterioration. We continue to see near-term downside risk to the 200 DMA (5723), and today's action only emboldens that view," Krinsky said. "Perhaps most importantly, semis in both cap-weighted and equally-weighted terms are at or near multi-year relative lows."

The VanEck Semiconductor ETF (SMH) which tracks the performance of the 25 largest and most liquid US exchange-listed companies, is essentially flat year-over-year, Krinsky noted.

"SMH has made zero net progress over the last year. A breakdown at this point would leave much of the buyers over the last year underwater, creating significant overhead resistance," he added.

The equal-weight SPDR S&P Semiconductor ETF (XSD) versus the equal-weight Invesco S&P 500 Equal Weight ETF (RSP) is also close to breakdown. "So it's more than just an NVDA story," he said.

Stellantis, Nvidia, Tesla are among the stocks moving in premarket trading

Check out the companies making headlines before the bell:

• Stellantis, Ford Motor, General Motors — Shares of automakers dropped after the American Automotive Policy Council — a lobbying group that represents all three — issued a statement Monday saying the Trump administration should exempt from the tariff increase companies that comply with the 2020 United States-Mexico-Canada Agreement signed during Trump's first term. GM and Ford slipped 1% and 0.6%, respectively, while Stellantis slumped 3.4%.
• Nvidia — Shares fell an additional 3%, extending the chipmaker's nearly 9% decline Monday after President Donald Trump enacted tariffs on Canada and Mexico starting Tuesday. Investors remain concerned about how tariffs and greater export restrictions will affect Nvidia's business in China. After Monday's sell-off, Nvidia was worth $2.79 trillion and its shares were trading at the same price they were last September.
• Tesla — Shares were down 3% premarket after data from the China Passenger Car Association showed the EV company's sales of vehicles made in China dropped nearly 50% in February from the same period a year ago. Overall, Tesla sold more than 30,000 of these vehicles — the fewest in more than two years.

Bitcoin erases all of its gain from Trump crypto reserve announcement

The price of bitcoin failed to recover the $85,000 level — where it traded before President Donald Trump's announcement of a U.S. crypto reserve sent it soaring — after a sell-off driven by tariff concerns knocked it down.

Bitcoin was last lower by 2% on Tuesday at $83,508.78, according to Coin Metrics, and off its all-time high by 23%.

Coinbase and Robinhood fell 2% and 4%, respectively, in premarket trading. Strategy, formerly known as MicroStrategy, lost 4%.

Investors and analysts warn that economic uncertainty could keep its hold on bitcoin throughout March, with the crypto industry absent a specific catalyst. After reaching its record in January, it posted its worst month since 2022 in February.

AI cloud-based GPU provider CoreWeave files for IPO on Monday afternoon

CoreWeave, which provides cloud-based Nvidia graphics processing units to companies such as Meta and Microsoft, filed to go public on the Nasdaq on Monday afternoon.

The company chose "CRWV" as its new ticker symbol. CoreWeave quickly rose in popularity after OpenAI's release of ChatGPT. Since then, the company has been increasing its focus on artificial intelligence and graphics rendering to meet demand.

Last year, CoreWeave generated $1.92 billion in revenue, 62% of which came from Microsoft.

CoreWeave's initial public offering debut comes amid a broad market sell-off. On Monday, Nvidia fell nearly 9%, shedding $265 billion in market capitalization, after President Donald Trump confirmed tariffs on goods from Canada and Mexico would officially take effect on Tuesday.
