Stock Market Update

[BRIEFING.COM] With the support and influence of the mega-cap stocks, the selling activity beneath the surface hasn't had any meaningful impact on the market-cap-weighted indices (or even the price-weighted Dow Jones Industrial Average for that matter).

Selling activity was more apparent earlier when breadth favored declines at both the NYSE and Nasdaq. Things have changed, though, with the move to new highs. 

Advancers now lead decliners by a roughly 5-to-4 margin at the NYSE and the Nasdaq. Even so, the equal-weighted S&P 500 (-0.2%) remains stuck below the unchanged mark.

Small-cap stocks have perked up a bit. The Russell 2000 is up 0.7% and just shy of its best levels of the session.
