Now that I think about it, this short GREK trade might be a decent one. If there is a bailout, its likely to squeeze something 10-20%, maybe more? But if Greece gets out of the EUR, its likely to tank 50-60% (in line with the study mentioned earlier). Potentially more as people create a selling climax after being hit with such a huge overnight loss
Ideally I would want to only short Greece's euros but since you can't do that, shorting the stock market becomes a 2nd option. I might get in this. No big or even medium size, I haven't macro traded in a while and I'm a little rusty but I think this one could work
