Key Points

Stocks fell Wednesday as Wall Street once again sold highflying artificial intelligence stocks.

These stocks made notable moves:

Tesla dropped 4.6%. The electric-vehicle maker gained 3.1% the previous session to hit a record closing high of $489.88, boosted by a price-target upgrade from Mizuho. California regulators are giving Tesla 90 days to change its autopilot advertising. If the company doesn’t change its policies, its dealer and manufacturing licenses will be suspended for 30 days, said the California Department of Motor Vehicles.

Warner Bros. Discovery fell 2.4%. The board of Warner Bros. urged shareholders to reject an acquisition offer from Paramount Skydance. Warner Bros. recommended shareholders back an existing deal with Netflix instead. Paramount stock slid 5.4% on Wednesday, and Netflix rose 0.2%.

Oracle declined 5.4%. The Financial Times reported Blue Owl Capital won’t back a $10 billion deal for Oracle’s next artificial-intelligence data center. The report, citing people familiar with the matter, said negotiations have stalled on worries about the tech giant’s rising debt and large AI investments. Oracle spokesperson Michael Egbert said in a statement to Barron’s that development partner Related Digital “selected the best equity partner from a competitive group of options, which in this instance was not Blue Owl.”

“Final negotiations for their equity deal are moving forward on schedule and according to plan,” he said.

Lennar dropped 4.5% after the home builder reported weaker-than-expected earnings for its fiscal fourth quarter and issued disappointing guidance. It has been a difficult time for companies in the housing space as buying costs have remained high and home sales slow.

Medline soared 41% to $41 from its initial public offering price of $29. The medical-surgical product supplier opened for trading Wednesday at $35 a share. Medline raised $6.26 billion in the IPO.

U.S. shares of Hut 8 rose 9%. Fluidstack will pay $7 billion for a 15-year lease at Hut 8’s data center in Louisiana. Anthropic, the developer of the Claude AI models, will be the end user for server clusters operated by Fluidstack, the companies announced.

Texas Pacific Land gained 7.6% after the landowner struck an agreement with Bolt Data & Energy to develop data-center campuses on Texas Pacific property in West Texas. Texas Pacific was the top-performing stock in the S&P 500 on Wednesday.

U.S. shares of DBV Technologies surged 25% after the French pharmaceutical company reported positive top-line results from a Phase 3 trial of its peanut patch, which treats children with peanut allergies aged between 4 and 7.

Jabil gained 1.8% after the supplier of electronic parts beat quarterly earnings and revenue estimates in its fiscal first quarter and raised its fiscal-year forecast.

Nucor tumbled 1%. The steel company issued fourth-quarter guidance that missed Wall Street expectations. “Earnings in the fourth quarter of 2025 are expected to decrease across all three of our operating segments as compared with the third quarter of 2025, driven by seasonal effects and fewer shipping days in Nucor’s fiscal quarter,” the company said in a statement.

Fortinet declined 3.8% to $79.38. Analysts at J.P. Morgan downgraded shares of the cybersecurity company to Underweight from Neutral and reduced their price target on the stock to $75 from $85.

Micron Technology fell 2.9%. The memory-chip maker was set to report fiscal first-quarter earnings after the close of trading Wednesday.

Shares of packaged-food company General Mills gained 3.4% after posting better-than-expected adjusted earnings in its fiscal second quarter.
