Stock Market Update

[BRIEFING.COM] The S&P 500 trades near its low of the session, just two points above its prior close. For now, the flat line has held as support for the index. 

The equal-weighted S&P 500 is down 0.5%, though, reflecting more selling under the surface. Even Apple (AAPL 235.21, -2.41, -1.0%), which was up as much as 4.0% after reporting earnings, has turned lower. 

Other mega caps remain in positive territory, providing some support to index performance. Alphabet (GOOG 206.85, +4.22, +2.1%), Tesla (TSLA 412.46, +12.18, +3.1%), and Amazon.com (AMZN 238.79, +4.19, +1.8%) are standouts in that respect.
