Nasdaq participation
I don't want to make anything dramatic out of this yet, because it could change, and it hasn't been a consistent pattern. But despite the Nasdaq Composite charging ahead by more than 2% so far today, fewer than 55% of securities on the Nasdaq are advancing. That's thanks to some relative weakness in smaller-cap stocks.
This would be the first time since 2002 the Nasdaq rallied so hard on such poor internal participation.
