Key Points

Stocks dropped Tuesday, putting an end to the S&P 500’s seven-session winning streak. The U.S. government shutdown, meanwhile, entered its seventh day.

These stocks made notable moves Tuesday:

Tesla fell 4.5%. The electric-vehicle maker said it would roll out a pair of vehicles starting below $40,000, including a new standard Model Y starting at $39,900. The Model Y has limited paint options and a base mileage per charge of about 320 miles, 40 miles less than premium Model Y products. A new Model 3 will start at $36,900, Tesla added. Prior to those announcements, Tesla said it had begun rolling out version 14 of its Full Self-Driving driver-assistance product.

Advanced Micro Devices rose 3.8%. Shares surged 24% on Monday after the chip maker announced a long-term deal to become a key supplier to OpenAI’s artificial-intelligence infrastructure buildout. AMD’s market cap grew $63.36 billion to $330.6 billion on Monday, according Dow Jones Market Data, the stock’s largest one-day market cap gain on record. Jefferies analysts upgraded the stock to Buy from Hold on Tuesday.

Chip rival Nvidia traded down 0.3% and Broadcom rose 0.3%. Both stocks suffered moderate losses on Monday after the AMD-OpenAI announcement.

Dell Technologies rose 3.5% after the maker of computers and artificial-intelligence servers boosted its long-term financial guidance. Dell said it was targeting annual revenue growth of 7% to 9% through fiscal 2030, up from a previous range of 3% to 4%. Its adjusted per-share earnings growth target was raised to 15% or better, almost double its prior forecast of 8%.

Ford Motor fell 6.1%. A fire that occurred three weeks ago at Novelis, a supplier of aluminum sheet to the auto industry, likely will pressure production at Ford and other auto makers, The Wall Street Journal reported on Monday.

AppLovin rose 7.6% after tumbling 14% on Monday. Bloomberg reported that the Securities and Exchange Commission was investigating the data-collection practices of the mobile advertising tech company. An AppLovin spokesperson told Barron’s that “generally, we do not comment on the existence or nonexistence of any potential regulatory matters. That said, as a global public company, we regularly engage with regulators and if we get inquiries we address them in the ordinary course. Material developments, if any, would be disclosed through the appropriate public channels.”

International Business Machines gained 1.6% after reaching a partnership with Anthropic that will integrate its large language models into certain IBM software products. The stock traded as high as $301.04 during the session, a new intraday record.

Trilogy Metals skyrocketed 211% to $6.50 after the White House said late Monday it was investing $36.5 million, or about 10%, in the small Canadian miner company. The U.S. government will take warrants to purchase an additional 7.5% of the stock.

Constellation Brands rose 1% after the company reduced its fiscal-year guidance, even as fiscal second-quarter earnings and sales beat analysts’ expectations. The company estimated earnings for the year of $9.86 to $10.16 a share, down from prior guidance of between $10.77 and $11.07. Like many other alcohol and beverage companies, Constellation has struggled as younger consumers cut back on drinking alcohol because of rising prices, health concerns, and the popularity of other recreational options. The stock has fallen 37% this year.

SoFi Technologies rose 6.8% following a Politico report that said the Trump administration was considering selling parts of the federal government’s roughly $1.6 trillion student loan portfolio to the private market.

Aehr Test Systems sank 17%. While the semiconductor equipment maker posted slightly better-than-expected fiscal first-quarter results, Aehr swung to a loss from a year earlier. CEO Gayn Erickson said the company remained cautious due to ongoing tariff-related uncertainty and wasn’t reinstating formal guidance yet, but was “confident in the broad-based growth opportunities ahead across AI and our other markets.”

Dollar Tree declined 3% to $85.04 after shares of the discount retailer were downgraded to Underperform from Hold at Jefferies and the price target was reduced to $70 from $110. The analysts cited a downbeat combination of tariff pressures, rising competition, and shrinking margins.
