First, we have a gap to fill around 4000 on SPX. Second, while we have been pushing new highs in the past couple weeks, we have a bearish divergence on both the MACD and RSI which are making lower highs with these new price highs. Third, there is a possible ascending wedge (bearish formation). Lastly, these 'push new highs and then fail' reversal days are not a good sign. Easy target is 4000; more likely though we find 3600-3800 in the coming weeks.
