European stocks were little changed as German investor confidence surged, offsetting an unexpected decline in U.S. sales of existing homes.

German investor confidence increased to the highest in 2 1/2 years in January. The ZEW Center for European Economic Research in Mannheim said its index of investor and analyst expectations, which aims to predict economic developments six months in advance, climbed to 31.5 from 6.9 in December. That’s the highest since May 2010. Economists forecast a gain to 12.
