Stock Market Update

[BRIEFING.COM] The stock market is in the midst of another sleepy holiday-week session, with the S&P 500 (flat), Nasdaq Composite (flat), and DJIA (-0.1%) oscillating around their flatlines. 

A solid gain in the top-weighted information technology sector (+0.4%) gave the major averages a slight boost at the opening, with NVIDIA (NVDA 191.22, +2.61, +1.38%) leading the advance. 

The materials sector (+0.5%) also trades higher as metal prices continue to rise, but the broader market has turned lower since the open, with nine S&P 500 sectors now trading in negative territory.

The losses are modest and paced by the consumer discretionary sector (-0.5%). Tesla (TSLA 477.59, -7.81, -1.61%) is a laggard among mega-cap names, while cruise line stocks such as Royal Caribbean (RCL 285.52, -8.60, -2.93%) and Norwegian Cruise Line (NCLH 22.58, -0.58, -2.52%) face some profit-taking after outperforming over the past two weeks. 

Outside of the S&P 500, the Russell 2000 (-0.6%) and S&P Mid Cap 400 (-0.3%) are underperforming.
