Stocks sank Monday with the S&P 500 on track to snap a five-quarter winning streak ahead of the White House's planned tariffs rollout. Tech stocks were falling the most Monday.

These stocks were moving Monday:

Tesla was down 5.9% at $247.89. The electric-vehicle maker declined 3.5% on Friday but ended the week higher and snapped a nine-week losing streak. Coming into Monday, Tesla has declined 35% this year. The company is expected to release first-quarter deliveries on Wednesday. Analysts at Stifel reduced their price target on Tesla to $455 from $474 and trimmed their near-term delivery forecasts.

General Motors was up 0.1% after falling earlier in the session, Ford Motor rose 2.1%, and Jeep maker Stellantis declined 2.3% after President Trump told NBC News he didn't care if foreign automakers raised their prices for U.S. consumers because of plans to slap a 25% tariff on imported automobiles. "I couldn't care less, because if the prices on foreign cars go up, they're going to buy American cars," Trump said. "I hope they raise their prices, because if they do, people are going to buy American-made cars. We have plenty."

CoreWeave fell 8.8% to $36.47. The artificial-intelligence start-up began trading Friday. It opened at $39 a share, below its initial offering price of $40, and ended the session at $40. CoreWeave is a pure play on AI, with all of its revenue coming from cloud rentals of AI servers that use Nvidia chips.

Nvidia, meanwhile, dropped 4.8% following the disappointing CoreWeave IPO. Coming into Monday, the AI chip maker has declined 18% this year. Palantir Technologies fell 4.3%. Shares of the data-analytics company have risen 8.7% in 2025 including Monday's decline.

Moderna was down 12%. The latest news to hit the stock and the greater biotechnology sector was the resignation on Friday of Peter Marks, who led the Food and Drug Administration's Center for Biologics Evaluation and Research. Shares of vaccine maker Moderna have tumbled 34% this year including Monday. As Josh Nathan-Kazis, a reporter for Barron's, has noted, the company faces a hostile political environment for its technology, a looming patent problem, and the potential threat of the removal of the stock from the S&P 500, making for day-to-day volatility.

LPL Financial said it would acquire Commonwealth Financial Network, a privately owned wealth management company with about 2,900 financial advisors, for roughly $2.7 billion in cash. Shares of LPL Financial, the wealth management company, fell 3.8%.

Mr. Cooper jumped 17% to $121.90 after the mortgage company agreed to be acquired by Rocket Cos. in a $9.4 billion all-stock deal. Mr. Cooper shares were valued at $143.33 based on last week's closing prices. Rocket declined 5.2%.

Boeing fell 1.6%. The plane maker announced an order for 50 737 MAX jets from aircraft lessor BOC Aviation and a report Friday from Reuters said Boeing was nearing a sale of its Jeppesen navigation business.

Canada Goose declined 5.5% to $7.79 after shares of the Canadian winter apparel brand were reduced to Underweight from Equal Weight with a price target of $8, down from $10, at Barclays.

Earnings reports are expected Monday from PVH Corp. and Progress Software.

Reports are expected later in the week from nCino, RH, BlackBerry, Conagra Brands, Acuity, and Lamb Weston Holdings.
