03:58 PM EST, 11/12/2025 (MT Newswires) -- US equity indexes were mixed ahead of Wednesday's close amid a decline in almost all the Magnificent-7 stocks and expectations of a House vote to end the longest federal shutdown in the country's history.

The Nasdaq fell 0.2% to 23,410.1, but was off session lows. The S&P 500 climbed 0.1% to 6,854.3, clawing back intraday declines. The Dow Jones Industrial Average advanced 0.8% to 48,300.6. Healthcare, financials, and materials led gainers intraday, while communication services, energy, and consumer discretionary were the steepest decliners.

For the week, technology and consumer cyclicals sat at the bottom of sector charts, while basic materials, healthcare, and energy 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 six declining Mag-7 stocks, the worst performer was Meta Platforms ( META ) , down 2.7%. Palantir ( PLTR ) , the poster child for AI-trade, fell 4.6%, the biggest laggard among stocks with a market capitalization of more than $200 billion.

The most telling indicator of this sentiment shift comes from short interest figures across major tech subsectors, S&P Global said in a Tuesday research note analysing the sell-off in technology last week. The companies in the North America Semiconductors and Semiconductor Equipment category now face a short interest of 0.285%, the highest level seen this year.

"These figures represent a significant move against the tech sector by institutional investors and hedge funds, who appear increasingly convinced that a correction is warranted after months of AI-fuelled enthusiasm drove valuations to ever higher levels," the S&P note said.

Meanwhile, the chamber is set to vote Wednesday evening on the Senate-backed bill to reopen the federal government, CNN reported. House Speaker Mike Johnson told reporters he's "very optimistic" about the vote tally tonight, the news report said.
