Another sign the 17-nation bloc is still struggling to build up momentum occurred on Thursday, as the EU statistics agency said that industrial output shrank unexpectedly in October. Soon after the report the single currency pulled back from 1.38 and was traded at 1.3764. The industrial output, which is considered as a leading indicator of economic health as businesses reacts quickly to any changes in the business cycle, sank 1.1% in October. This comes after a 0.3% drop a month earlier, and well below analysts' expectations for a 0.3% gain. On a yearly basis, however, output advanced 0.2% in the reported period, while analysts estimated a more positive reading of 1.1% annual growth.
