LONDON, May 24 (Reuters) - European shares edged lower on Friday, led by auto and banking shares as investor sentiment remained shaky on concerns about a possible rolling back of U.S. monetary stimulus.
The pan-European FTSEurofirst 300 index was down 0.4 percent at 1,225.26 points at 0941 GMT, with selling momentum accelerating as the index approached Thursday's intra-day low at around 1,223 points.
"(I've) just seen a few stop levels triggered there on decent volume," Peter Rice, head of investment strategy at Logic Investments, said. "We're now close to yesterday's lows, a break below will likely see further selling pressure."
Autos and banks were the top fallers, down 1.3 percent and 1 percent, respectively.
Volume was thin at 26 percent of the FTSEurofirst 300's full-day average for the past 90 days, with some traders already away ahead of a long weekend in Britain and the United States.
