The 30-stock index fell as much as 586 points. The S&P 500 declined 1.4 percent to end at 2,677.67 — erasing its year-to-date gains — with industrials as the worst-performing sector. It also briefly broke below its 100-day moving average, a key technical level. The Nasdaq composite fell 1.3 percent to 7,180.56 and dipped below its 50-day moving average. The U.S. will set tariffs of 25 percent for steel and 10 percent for aluminum, the president said. It is unclear whether they will apply to all imports or only metals from certain countries.
