In summary, the line of least resistance is still to the upside. After getting to all time highs a week ago, the market has lost some of its mojo this week. The overbought conditions are slowly beginning to take a toll.

SP- 500 support is at this week's lows around 4120, with stronger support just below the March highs, and the major support at 3870. If 4000 is penetrated that would be a short term negative, and if 3870 is penetrated that would be a major change of trend.
