NEW YORK — Wall Street ticked to a record on Tuesday, as stocks zigzagged following mixed profit reports from UnitedHealth, General Motors and other big companies.
The S&P 500 rose 0.4% and edged past its prior all-time high set a couple weeks ago. The Dow Jones Industrial Average dropped 408 points, or 0.8%, and the Nasdaq composite climbed 0.9% as the stock market cleaved between winners and losers.
The swings were even bigger in foreign-currency markets, where the U.S. dollar's value slid against its peers again. Shortly after U.S. stocks finished Tuesday's trading, the dollar was down more than 1% against the euro, the Japanese yen and the Australian dollar, among others. An index measuring the U.S. dollar's strength against several of its competitors dropped to its lowest point since 2022.
The slide continues a sharp drop for the U.S. dollar since President Donald Trump threatened tariffs against several European countries that he said opposed his taking control of Greenland. Such threats, along with worries about risks like the U.S. government's heavy debt, have periodically pushed global investors to step back from U.S. markets, a move that's come to be called ''Sell America.''
On Wall Street, Corning helped lead the market higher and climbed 15.6% after announcing a deal with Meta Platforms worth up to $6 billion. Corning will supply optical fiber and cable to help build out data centers for Meta, enough that Corning is expanding its optical-fiber manufacturing facility in Hickory, North Carolina.
Also supporting the U.S. stock market were gains for General Motors, which rose 8.7%, and hospital-operator HCA Healthcare, which rallied 7.1%. Both delivered profits for the end of 2025 that topped Wall Street's expectations. Each also approved programs to send billions of dollars to their investors by buying back their own stock.
They helped offset a tumble for UnitedHealth Group, which sank 19.6% despite reporting a profit for the latest quarter that was a bit better than analysts expected. More attention was on the company's forecast for revenue in the upcoming year, which fell short of Wall Street's expectations and could be weaker than it was in 2025.
Health care stocks also felt tremendous pressure from a projected rate increase for Medicare Advantage by the U.S. government, which fell well short of what investors had hoped. Humana skidded by 21.1%, Elevance Health dropped 14.3% and CVS Health sank 14.2%.
