Stock Market Update

[BRIEFING.COM] The S&P 500 (+1.0%), Nasdaq Composite (+1.4%), and DJIA (+0.8%) maintain significant gains, bringing them closer to recent record highs. 

The advance has been broad-based, with ten S&P 500 sectors trading higher. Advancers outpace decliners by a roughly 4-to-1 ratio on the NYSE and a roughly 3-to-1 clip on the Nasdaq. 

Mega-cap and tech names contribute to the advance, as the Vanguard Mega Cap Growth ETF (+1.1%) is up over 1.0%. The information technology sector (+1.5%) holds the widest gain, supported by strength in chipmakers that push the PHLX Semiconductor Index (+2.2%) higher. 

Apple (AAPL 263.36, +11.07, +4.39%) is a standout so far, trading higher amid strong iPhone 17 sales in the U.S. and China. 

While the market's largest names certainly contribute to the major averages' gains, they are not the sole driver of the index-level advance, as the S&P 500 Equal Weighted Index (+0.9%) performs similarly to the market-weighted S&P 500 (+1.0%). 

The market did not receive any economic data today amid the ongoing government shutdown. White House Economic Advisor Kevin Hassett told CNBC that the shutdown "is likely to end sometime this week."
