German DAX index edged lower on Tuesday as worries intensified over the inability of Greek parties to form a new government. The losses were limited as data showed industrial output in Germany accelerated three times as much as economists predicted in March. BMW retreated from previous gains and dropped 1.8%. On the upside Deutsche Telekom climbed 1.7% and Fresenius Medical surged 1.5%. At the moment of writing DAX 30 is 0.49% or 32.47 points down at 6,537.04.
