Blast off breadth
Things could always change before the close, but stocks are on track to do something they haven't done since at least 1962. The S&P 500 is on track for a record close, with more than 90% of issues advancing on the NYSE.
Such an overwhelming breadth tailwind has never happened before. There were only 2 days when more than 85% of issues advanced on a day the S&P set a record, on November 3, 1982 and July 11, 2013. Both preceded sustained bull runs.
Looking at all record closes with more than 80% advancing issues, the S&P 500 rallied every time over the following four months. Tough time to be a bear.
