Divergences are taking place by both ratios as the S&P has been diverging since earlier this year and the NDX has been diverging the past few years.
The divergences by themselves do not mean the market has to head south right or a bear market is ready to start. Historically when fewer and fewer stocks are powering a bull market rally, it does reflect a thinning of the market and could result in unimpressive gains going forward.
Stock bulls want to see these ratios heading higher, not continuing to diverge.
