US stocks slump amid eurozone worries

US stocks closed sharply lower Monday as signs of political instability in Italy and Spain renewed worries about the the eurozone's long-running public debt crisis. At the closing bell, the Dow Jones Industrial Average was down 129.25 points (0.92 percent) at 13,880.54. The S&P 500-stock index fell 17.42 (1.15 percent) to 1,495.75, while the tech-rich Nasdaq Composite Index shed 47.93 (1.51 percent) at 3,131.17. After the US equity markets hit highs unseen in more than five years last week, stocks were "pressured by political concerns out of the eurozone," Charles Schwab & Co. said in a market note.
