US stocks opened solidly higher Friday after an extremely volatile week, helped by revived confidence in the eurozone and positive US consumer data for July. The Dow Jones Industrial Average rose 101.15 points (0.91 percent) to 11,244.46 in the first 15 minutes of trade, adding to Thursday\'s 423-point, 3.95 percent rebound. The broader S&P 500 was up 8.58 points (0.73 percent) at 1,181.22; and the Nasdaq Composite pushed up 7.68 points (0.31 percent) to 2,500.36. The positive opening followed a strong day on the European stock markets, where indices were up 2-4 percent on renewed confidence in eurozone finances after the IMF gave its approval to Portugal\'s restructuring path -- allowing a new release of bailout funds -- and bank shares calmed on rules restricting short sales in four eurozone countries. Also helping was data showing an 0.5 percent rise in US retail sales in July, and an upward revision to the originally flat June number -- a sign that US consumer spending might be healthier than economists believed.
