FRANKFURT, May 29 (Reuters) - European shares advanced early on Friday, with gains virtually across the board, after U.S. stocks climbed overnight and Asian markets followed suit, with the focus on U.S. economic data due later in the session.
At 0845 GMT, the FTSEurofirst 300 <
> index of top European shares was up 1.1 percent at 869.31 points. It closed 1.2 percent lower on Thursday, having fallen as much as 2 percent earlier in the session."We trade in a narrow range, up and down, without any clear direction," said Heinz-Gerd Sonnenschein, equity strategist at Postbank in Bonn, Germany.
The European benchmark index lost 45 percent in 2008 and fell further early this year, hitting a lifetime low on March 9. It rose 36 percent between that day and May 7, and has remained rangebound between about 823 and 878 points since then.
"We have lost the triggers from the company side ... on the company side it is quiet," Sonnenschein said, referring to the end of the first-quarter corporate earnings season.
"It's a mood of wait and see. There are no drivers to push the markets down but there's also no strong news to push the markets up."
LandesBank Berlin (LBB) pinpointed 2,500-2,600 points as a key area for the DJ EuroSTOXX 50 <
>, which was up 1.0 percent at 2,478.05 points."If it were able to jump over that hurdle, the charts would improve clearly, boding for a new technical upward potential," LBB said.
