Stock market today: World markets mostly lower after Wall Street snaps its recent rally

World shares are mostly lower after Wall Street's huge rally faltered last week. Japan's Nikkei 225 index shed 2.2% Monday while other major markets saw modest losses. On Friday, the S&P 500 slipped 0.7% from its all-time high. It initially climbed after mixed data on the U.S. job market bolstered hopes for easier interest rates. Later, it swung to a loss after one of its most influential stocks, Nvidia, took a rare stumble following its jaw-dropping rise. The Dow Jones Industrial Average slipped 0.2%, and the Nasdaq fell 1.2%. It was just the third losing week for the S&P 500 in the last 19.
