The FTSEurofirst 300 index of leading European shares extended its gains on Friday to trade up 0.5 percent at 1,516.9 points after a key survey showed U.S. consumer sentiment rose to a three-year high. The Reuters/University of Michigan Surveys of Consumers said its preliminary January reading on consumer sentiment came in higher-than-expected, propelled by falling gasoline prices and a favorable view of personal finances and economic growth. Britain's FTSE 100 rose 0.1 percent, while Germany's DAX added 0.4 percent and France's CAC 40 rose 0.7 percent. U.S. stocks pared their earlier losses. Among the region's gainers, Vinci rose 5.2 percent on bid speculation after the holding company of French billionaire Francois Pinault bought a 5.1 percent stake in the public works and transport concessions group.
