US stocks Thursday snapped a three-day losing streak, catalyzed by stronger Chinese trade data and better sentiment on the European economy. The Dow Jones Industrial Average gained 27.65 (0.18 percent) at 15,498.32. The broad-based S&P 500 tacked on 6.57 (0.39 percent) to 1,697.48, while the tech-rich Nasdaq Composite rose 15.12 (0.41 percent) to 3,669.12. Hugh Johnson, chief executive of Hugh Johnson Advisors, said the market was primed for a jump after notching three straight declines. Chinese trade data for July showed that exports increased 5.1 percent year-on-year to $186.0 billion, while imports rose 10.9 percent to $168.2 billion, revealing some ongoing strength in the Chinese economy. Johnson also cited remarks from European Central Bank President Mario Draghi that the European economy appeared to be stabilizing and fresh German trade data that showed a pickup in exports. These were \"a catalyst for an oversold bounce,\" Johnson said.
