Hedge funds big sellers of EUR/CHF overnight

Hedge funds were reportedly large sellers of EUR/CHF throughout the European session yesterday. The German constitutional court decision next Wednesday is the big looming risk event and with pressure piling onto European banks, the safe bet seems to be to sell EUR/CHF. I still don’t understand why anyone would want to buy CHF if they think a banking crisis is about to happen anywhere, but that’s just me I guess.
