S&P 500 losing streak extends to ninth straight day

The S&P 500 ended lower on Friday for a ninth straight day, the longest losing streak for the benchmark index in more than 35 years, as investors stayed on edge ahead of an uncertain U.S. election. The tech-heavy Nasdaq also ended lower for a ninth-consecutive session, while the Dow industrials closed down for a seventh straight day. Investors have been unnerved by signs of a tightening presidential race between Democrat Hillary Clinton and Republican Donald Trump.
