Germany's ZEW institute said on Tuesday its gauge of investor confidence in Europe's largest economy rose in July, though it said analysts were still waiting for evidence of an upswing in the domestic economy. The Mannheim-based think tank said its expectations indicator for Germany rose by one point to 48.4 from 47.4 in June. The consensus forecast of 28 analysts polled by on Friday was for a drop to 47.0. Forecasts ranged from 44.0 to 49.3 . "This is in principle pleasing news, but financial analysts appear still to be waiting for significant domestic impetus to boost the export-driven recovery," ZEW President Wolfgang Franz said in a statement. A gauge of current conditions advanced to minus 69.3, from minus 69.8 in June, while a measure of expectations for the 12-nation euro zone fell to 55.5, from 56.8.//
