Stocks surged on Wall Street, breaking a nine-day losing streak, after the FBI said newly discovered emails didn't warrant any action against presidential candidate Hillary Clinton. The Dow Jones industrial average jumped 371 points, or 2.1%, to 18,260 Monday. Investors have been anxious over signs that the US presidential race was tightening, reports the AP. The Standard & Poor's 500 index is coming off its longest losing streak since 1980. Monday's surge erased more than half of those losses. The S&P 500 index gained 46 points, or 2.2%, to 2,131. The Nasdaq composite jumped 119 points, or 2.4%, to 5,166. Banks and health care companies rose more than the rest of the market.
