NYSE New Highs Contract While SPX Makes 50-day High

Also notable from Friday afternoon is the fact that new highs contracted substantially while the S&P made a 50-day high. The percentage of stocks hitting new 52 week high dropped from a little over 7% on Thursday to under 5% on Friday. I looked at other times the SPX made a 50-day high while the drop in new highs equaled 2% or more of the total issues.

What I found interesting and compelling about the above test was NOT the size of the average decline. In fact that was somewhat weak. It was the fact that 95% of instances closed below the trigger day close at some point in the next 5 days. This suggests that while the lagging new highs might not indicate an immediate selloff, the market has consistently struggled to move higher.
