Wall Street stocks surged Tuesday on optimism about a rebound in the United States, as more states emerge from coronavirus shutdowns and drugmakers step up efforts to find a vaccine. At the closing bell, the Dow Jones Industrial Average stood at 24,995.11, up 2.2 percent. The broad-based S&P 500 gained 1.2 percent to 2,991.77, while the tech-rich Nasdaq Composite Index added 0.1 percent at 9,340.22. The gains came as the New York Stock Exchange resumed floor trading after shuttering for two months due to the coronavirus. jmb/cs
