Stock Market Update

[BRIEFING.COM] The S&P 500 (-0.8%), Nasdaq Composite (-0.8%), and DJIA (-0.9%) trade at their worst levels of the day, with the former two indices sitting below their 50-day moving averages. 

Breadth figures have deteriorated throughout the session, with decliners now outpacing advancers by a roughly 3-to-1 clip on the NYSE and a roughly 2-to-1 margin on the Nasdaq. 

Perhaps even more detrimental to the state of the major averages is the widening losses across the market's largest names. The Vanguard Mega Cap Growth ETF is down 0.9%, which pushes its month-to-date loss to 3.8%.
