(ANSA-AFP) - FRANKFURT AM MAIN, APR 16 - German investor confidence rose more than expected in April, a key survey showed Tuesday, on growing optimism about the economic outlook at home and abroad. The ZEW institute's economic expectations index rose for the ninth consecutive time, climbing by 11.2 points month-on-month to reach 42.9 points. Analysts surveyed by FactSet had predicted a smaller jump to 35 points. "A recovering global economy is boosting expectations for Germany, with half of the respondents anticipating the country's economy to pick up over the next six months," said ZEW president Achim Wambach. "Further contributing to the heightened optimism are the much improved assessments of the situation and economic expectations in Germany's export destinations," he added. (ANSA-AFP).
