U.S. Stocks Open Lower, On Track For 6th Straight Drop

U.S. stocks opened lower, on track for their sixth straight drop, after both the Federal Reserve and Bank of Japan expressed concern about the potential fallout from a "Brexit." The S&P 500 shed 7 points, or 0.4%%, to 2,063. The Dow industrials were off 56 points, or 0.3%, to 17,576. The Nasdaq Composite slid 22 points, or 0.5%, to 4,812. U.K. voters head to the polls on June 23 to decide whether to remain a member of the European Union, or to leave. Economists and market strategists say an "out" vote could instigate widespread turmoil in global markets.
