The S&P 500 closed at 1885.52 this afternoon, eclipsing its prior all time highs. A wobbly March kept investors on their toes, but the worst sell offs of the month came from outside the S&P 500, hitting extended biotech, internet and growth-oriented names. The closing high once again confirms that the bull market dating to March 2009 is not over, and it also puts large cap stocks back on an upward path for the year after a difficult first quarter. The S&P is up 37 points, or two percent, since the close on New Years Eve, and the most recent gains will serve as ammunition from equity bulls as the second quarter unfolds. Below is a chart of the S&P 500 over the last six months. With the index now above the top end of the sideways range it had been in for the last month, is a breakout coming?
