I doubt there will be a compromise. They have not been able to come up with one when the deal was cut to go over the cliff when they negotiated the new debt ceiling. That was over a year ago. White House too stubborn and if they cut spending they risk the senate in 2014 and election in 2016.
If one is reached (it will be a lame one if that), market will react positively of course since Ben and his boys will be buying. Retail will jump on board and that is when they will really slam it down. Last 6 days was just practice.
