1) They make some progress and kick the can down the road again, short term up market and overall good.
2) Deal falls apart, Trump raises tariffs again. This is the end of the bull market, we are looking at a possible 1000 point fall in the ES but not in 1 day. Probably 90 point fall.
3) Trump was doing art of the deal mind games, and he was actually planning on doing a deal, it gets done, and we see a 1000 point up move in the ES as least 90 points upside in 1 day.
