The ZEW economic institute showed

Confidence among German investors beat analysts' expectations to reach its highest level since summer 2015 in April, a monthly survey by the ZEW economic institute showed Tuesday.
The institute's headline index measuring expectations for the coming months leapt to 19.5 points, from 12.8 in March. Analysts surveyed by Factset had predicted a much smaller increase, to 13.8 points.
ZEW compiles its investor confidence index based on a survey of 204 financial players in Germany.
