Stock Market Update

[BRIEFING.COM] The S&P 500 (+0.2%), Nasdaq Composite (+0.2%), and DJIA (+0.5%) are under pressure just before the close, as the major averages now sit considerably below earlier highs. 

Notably, mega-caps have given up the majority of their early advacne, with the Vanguard Mega Cap Growth ETF now up just 0.1% after trading as much as 0.7% higher today. 

Though semiconductor names have seen some profit taking from earlier levels, NVIDIA (NVDA 187.64, +4.50, +2.46%) remains a mega-cap standout, but weakness in Apple (AAPL 257.65, -2.31, -0.89%) and Microsoft (MSFT 456.59, -2.79, -0.61%) pressure the information technology sector (+0.8%) to its lowest levels of the session. 

Elsewhere, Amazon (AMZN 237.32, +0.67, +0.28%) and Tesla (TSLA 440.10, +0.90, +0.20%) are now flattish, which contributes to the consumer discretionary sector (+0.4%) giving up about half of its previous strength, while Alphabet's (GOOG 332.89, -3.42, -1.02%) underperformance keeps the communication services sector (-0.7%) firmly lower.
