Stocks and markets
Global stocks fell on Monday as North Korea's sixth and most powerful nuclear test sent investors searching for safer investments. The yen, gold, and sovereign bonds rose. South Korea's benchmark stock index fell by more than 1 percent, and Japan's Nikkei lost nearly 1 percent. Europe's major exchanges opened down by more than 0.5 percent but recovered some of those gains later. U.S. markets are closed Monday for Labor Day, but U.S. stock-index futures fell, with Dow Jones Industrial Average futures down by 0.2 percent, and S&P 500 and Nasdaq-100 futures down by 0.3 percent.
