US stock market today: Why is Dow Jones crashing while the S&P 500 and Nasdaq rise? Dow falls 260 points as inflation heats up and Trump heads to China

US stock market today: Dow Jones, S&P 500, and Nasdaq moving in opposite directions. Dow falls 260 points today as inflation heats up and President Donald Trump arrived in China for a major summit with Xi Jinping. S&P 500 and Nasdaq pushed higher, led by another powerful rally in chip stocks. A hotter-than-expected wholesale inflation print, and a Federal Reserve boxed into a corner have created one of the most unusual trading sessions of 2026.
