After a bunch of disappointing fundamental data and pessimistic comments from Europe, a release of German ZEW economic sentiment index acts like a sip of fresh air for Euro optimists. The ZEW Center for European Economic Research said a gauge of investor and analysts expectations, which is designed to predict economic performance during the next six months, soared to 54.6 in November, up from 52.8 a month earlier, beating analysts' estimates for a 54.0 reading. Nonetheless, market reaction was tepid, as EUR/USD has moved to 1.3542 and almost immediately plunged back to 1.35.
