I am puzzled why so many people on ET ( and this thread ) believe that SPX 1400 is of any real significance. Surely there aren't many technicians on ET, because if there actually were, we would not see such a thread even generate such "aggreement" in regards to the 1400 level.
The last time I checked the chart, the 50% retracement of the entire move down off the highs of last October at 1576.09 doesn't even come through until 1416.
