Just my personal feelings, but I am not keen on banking. Seems to me that the central banks have failed and were then propped up by their respective governments, but there is still a lot of trouble out there for banks. The commercial lending sector is facing down trouble on commercial real estate, which is still inflated. Credit issues for consumers are still a problem. While more related to US banks, we see that Freddie and Fannie bailed them out by buying something like 1/3 of all US mortgages so we now have a situation where our government owns homes through the bailout acquisitions of both Freddie and Fannie. I'm not sure if Germany and Deutsche Bank fall into that same sort of situation but I suspect that they do.
I'm very bearish right now on the financial sector. Strikes me that the best plays in the sector may well be sound regional banks that don't have either INTERNATIONAL exposure or lots of commercial real estate exposure.
Other sector plays may be in emerging market banks in Brazil, India, etc. But I'd be cautious of Chinese and Russian banks.
