Very unusual to see the S&P500 decline with the kind of positive breadth statistics seen Tuesday. Advancing volume among SPX components accounted for over 65% of total volume, and advancing issues also accounted for over 65% of total issues. It’s only happened eight other times in history, so very small sample. But interesting to see next-day gains were quite large, averaging nearly 2%…
