This is the most uncertainty I've seen going into the fed in my short time trading. As I've never seen any surprises, I've never really traded the fed. What industries do you play if they decide not to lower the rate today? What industries if they raise? and I know, banks are the obvious answer, but what else?
Whatever you decide to do will be wrong. No rate increase? The market will tank. Why? Because the Fed thinks the economy sucks. Rate increase? The opposite. Or maybe not. Or not not. Or not not not.
Think usually you can fade first move, but then it will go (whatever market you look at) in the original diriction. IMHO
