I think as long as 1545 holds on SPX a lot of big traders will remain confident and buy support that has held for 4 weeks. When that level breaks I would expect a quick trip down to the March high at 1531. Weekend news could tip the scales one way or the other as well. Most markets around the world including many major sectors in the U.S. topped out in Jan through March. Odd that the SPX is still hanging in there.
