Bespoke: S&P 500 Breadth Back at New Highs

"As mentioned in our prior post, the S&P 500 has quickly shaken off the weakness to start the month of May.  Although the index is still 1% below its 52-week high, breadth readings suggest that new bull market highs are in the cards.  As shown in the chart below, with today's rally the S&P 500's cumulative A/D line is now back to new bull market highs."http://www.bespokeinvest.com/thinkbig/2011/5
