US stock market today jolted: Dow, S&P 500 & Nasdaq snap reversal amid Trump’s Canada tariffs—Nvidia and Levi Strauss climb as airlines tumble

US stock market slipped in early trading on July 11, pulling back from record highs as Trumps tariff threat on Canada spooked investors. The S&P 500 fell 0.4% after hitting a record the previous day, while the Dow Jones dropped 257 points, or 0.6%. The Nasdaq Composite was also slightly down by 0.2%. Rising bond yields, with the 10-year Treasury jumping to 4.40%, added to the pressure. As markets react to fresh trade tensions, all three indexes are heading toward their first weekly loss in three weeks. Investors are closely watching Trumps next move on US-Canada trade.
