I expect the market to drift lower to 1440-1438 before an upside breakout on Thursday (or Friday) that will take price to 1500 very fast.
It will likely get to 1440-1438 on Tuesday (or Monday), followed by choppy good-for-daytrading sideways move that will setup the breakout.
NOTE:
If SPX moves above 1475 (or 1470 - aggressive), then expect a run up to 1500 regardless of the information above.
