Quote from Martinghoul:
I am long CHF, but, according to some data, Swiss banking system is quite exposed to the Eurozone peripherals. The Eurozone is also their main trading partner, still. I think it's still hard for Switzerland to not catch a cold when the Eurozone sneezes.
While I agree with this premise in general, I think you underestimate the Swiss Banking System a bit. There is a reason why they chose to forgo the the Euro and maintain the franc.
