Stocks declined Monday as Wall Street kicked off the final full trading week of 2025.
These stocks were moving:
iRobot plummeted 72% to $1.22 after the Roomba maker declared bankruptcy on Sunday. The company has struggled financially for years, and a proposed sale to Amazon.com fell through last year.
Tesla gained 3.8%. While shares of the electric-vehicle maker have risen 18% in 2025, Tesla is on track to sell fewer cars in 2025 than it did in 2024, marking the second consecutive year of declines. Separately, longtime Tesla super-bull Cathie Wood and ARK Invest sold more shares of the auto maker. The ARK Innovation ETF sold 60,898 Tesla shares on Friday, according to the firm's trading disclosures. The ARK Next Generation Internet ETF sold 27,095 Tesla shares.
Shares of Strategy, the world's largest corporate holder of Bitcoin, fell 6.8% after the company added almost $1 billion worth of the cryptocurrency for the second straight week. The stock has plummeted 43% this year, following the price of Bitcoin lower.
Zillow tumbled 10% as Alphabet's Google has begun testing a new advertising format for real estate listings that could threaten portals like Zillow. Alphabet stock was down 0.4%.
Tilray Brands dropped 4% and Canopy Growth fell 1.5% after the cannabis stocks rallied on Friday following reports President Donald Trump could loosen federal restrictions on marijuana as soon as Monday. A White House official told Barron's that no final decision had been made regarding the drug.
ServiceNow declined 12% to $764.51 after Bloomberg reported the software company was in talks to acquire cybersecurity start-up Armis in a deal that could reach $7 billion in value, citing people familiar with the matter. ServiceNow didn't immediately respond to a request for comment from Barron's.
The stock also was downgraded to Underweight from Sector Weight at KeyBanc with a $775 price target. The analysts cited some "worrying trends in IT back-office employment data that we believe raises the likelihood that NOW gets brought into the at-risk-from-AI tent in the coming quarters."
Rocket Lab stock dropped 9% despite completing its first mission for the Japan Aerospace Exploration Agency. Launches tend to be priced into Rocket Lab shares before they happen. Sometimes described as a mini-SpaceX, the space technology stock is up 120% this year.
Texas Instruments fell 0.4% to $178.67. The semiconductor company was downgraded to Sell from Buy at Goldman Sachs and the price target was slashed to $156 from $200. The downgrade was part of the firm's adjustment to ratings in the semiconductor sector as part of its 2026 outlook.
Chip maker Broadcom fell 5.5%, and software developer Oracle fell 2.1%. Both stocks racked up double-digit losses last week as so-so earnings reports failed to ease investors' concerns that the AI boom could be about to run out of road.
Las Vegas Sands gained 2.1% to $66.60. The casino company was upgraded to Buy from Neutral at Goldman Sachs and the price target was boosted to $80 from $64.
Lennar, General Mills, Jabil, Micron, Accenture, Birkenstock, CarMax, Darden Restaurants, FedEx, KB Home, Nike, Conagra Brands, Lamb Weston, Paychex, Winnebago Industries, and Carnival are among the companies expected to report earnings this week.
