European shares rose in early trading on Friday, buoyed by gains overnight in Wall Street and at steelmaker Thyssenkrupp , although persistent concerns over Greece kept a lid on the overall progress. The pan-European FTSEurofirst 300 index rose 0.4 percent to 1,530.97 points. Thyssenkrupp climbed 1.5 percent after Citigroup upgraded its rating on the stock to "buy" from "neutral".
