NEW YORK, Jan 18 (Reuters) - The euro rose more than 1 percent against the dollar on Tuesday on buying by sovereign funds and a surge in German investor sentiment, while global stocks hit a fresh 28-month high despite a sluggish U.S. open.
More gains for the euro are expected after the ZEW think tank in Germany said about 50 percent of investors now expect the European Central Bank will have to raise interest rates within the next six months. For details see: [
