After a rally to 1378 in the morning the SPX corrected and closed 6.5 points lower - that's actually the fourth worst day of the year...
As long as the market keeps making higher highs and higher lows pullbacks should be bought. I still like the comparison with 2010 though, i. e. a 50-point-correction sometime soon, and if the support at 1355ish breaks the correction should be underway.
