CHINA TRADE: China's stock market rebounded despite some disappointing news on its economy. China's exports shrank 5.5 percent last month compared with a year earlier, while imports tumbled 13.8 percent. August's figures were hit by disruption from a massive explosion at the busy Tianjin port and government-enforced factory shutdowns in the run-up to a huge military parade in Beijing last week. China's trade has been weak for months, reflecting muted global demand and a domestic slowdown.

ANALYST'S OPINION:"Now that China showed that it was not going to break down further, our market is taking back what it lost on Friday," said analyst Matt Maley, an equity strategist at Miller Tabak & Co. in Manhattan. "The market got hit hard on Friday because people were worried about China."
