European shares rose strongly last week, helped by Greece voting for austerity measures. Strategists said investors were now turning their attention to economic growth issues and the forthcoming corporate earnings season.
"Shares are rangebound and having tested the bottom of the range, and been supported by earnings and valuations, they may now test the higher end, and whether the macro picture, geopolitical picture, might be clearing somewhat.
