Financial Markets Wall Street

The roller-coaster ride for AI stocks snapped back down and dragged Wall Street lower. The S&P 500 fell 0.4% Tuesday, even though the majority of stocks within the index rose. The drops for stocks in the artificial-intelligence industry dragged the Nasdaq composite down 1.2%, while the Dow Jones Industrial Average dipped 0.2%. The weakness began in Asia, where Samsung Electronics tumbled 6.9% in Seoul despite offering what analysts called a strong forecast for upcoming results. AI stocks worldwide have been swinging because of worries their prices shot too high. Stocks also felt pressure from rising oil prices.

Oil prices are rising, and stock markets are dropping worldwide after President Donald Trump raised doubts about the temporary truce in the war with Iran. The S&P 500 fell 1% Wednesday after Trump said the agreement to pause fighting was “over,” though he added that he would allow negotiations to continue. The Dow Jones Industrial Average dropped 831 points, and the Nasdaq composite fell 1%. The price for a barrel of Brent crude climbed 8% to top $80, which sent Treasury yields higher on worries about worsening inflation. Stock indexes dropped across much of Europe and Asia.
