U.S. financial markets managed to shrug off China’s continuing stock turmoil Wednesday, as investors pushed major indexes up more than 2 percent. Earlier, the Shanghai Composite ended a volatile session down 1.3 percent, though markets in Japan and Australia posted gains; European indexes were down. Late afternoon on Wall Street, the Dow Jones Industrial average was up more than 350 points, a day after it closed down 204 in a seesaw session. The Chinese benchmark is down 20 percent over the past five days.
