The first is sensitivity to the Euro, as seen in the above chart.

Banks are largely a rate play. The automakers are floundering in a world of excess capacity and disappointed during Q2, and they also have the diesel scandal to overcome. VW looks cheap at 5.5X forward earnings. I like BASF, Siemens and a couple of other big industrial companies. But the index as a whole doesn’t persuade me.
