12:25 PM EST, 11/12/2025 (MT Newswires) -- US equity indexes were mixed in midday trading on Wednesday as the Nasdaq Composite and S&P 500 declined amid a retreat in all of the Magnificent-7 stocks.

The Nasdaq fell 0.5% to 23,361.1, with the S&P 500 edging lower at 6,844.4, but the Dow Jones Industrial Average rose 0.8% to 48,288.8. Healthcare, financials, and materials led the gainers intraday, while communication services and energy were the steepest decliners.

For the week, technology and consumer cyclicals sat at the bottom of sector charts, while basic materials, healthcare, and financials perched at the top, implying a sector rotation out of the so-called artificial intelligence trade could be in play amid valuation concerns.

Among the Mag-7 stocks, the worst performer was Meta Platforms ( META ) , down 2.4% intraday, giving up a bulk of this year's gains in the aftermath of its plan to raise the lower end of its full-year 2025 capital expenditure outlook by $4 billion to $70 billion-$72 billion. Next year, the company expects capex growth to be "notably larger" amid higher AI-related expenses.

Palantir ( PLTR ) , the poster child for AI-trade, was the biggest laggard intraday among stocks with a market capitalization of more than $200 billion, which includes all the Mag-7 stocks. The company has fallen out of favor after its Q3 beat-and-raise on Nov. 3 failed to justify its lofty 85 times price-to-sales ratio.
