Nasdaq enters correction territory as AI-linked selloff deepens

Reporting Notes

Nasdaq’s official index history page showed the Composite at 24,451.75, down 4.99% from its previous close on Nov. 5; this is an intraday snapshot, not the final session close. Reuters and the Associated Press independently reported the technology-led decline and gave earlier intraday snapshots. The 10% correction threshold is calculated against the Oct. 6 record close of 27,599.89 reported by Reuters. Market explanations are attributed investor concerns, not a verified single cause.

A market snapshot crosses the 10% line

A sharp technology-led selloff pushed the Nasdaq Composite more than 10% below its record closing high on Thursday, placing the index in correction territory for the first time in the current retreat. Nasdaq’s official index page showed the Composite at 24,451.75, down 4.99% from its previous close during Nov. 5 trading. Reuters reported the record close was 27,599.89 on Oct. 6; the gap between that peak and the Thursday snapshot was about 11.4%.

The reading is an intraday snapshot, not a final closing result. The Associated Press reported an earlier 1:46 p.m. Eastern snapshot in which the Nasdaq was down 5.2%, the S&P 500 3.9% and the Dow Jones Industrial Average 3.1%. Those figures describe the market at that time, not where the indexes ended the day.

AI and chip shares led the retreat

The decline followed a second day of heavy selling in semiconductor and data-centre companies. Reuters reported that Qualcomm shares fell after smartphone-chip sales missed Wall Street estimates, while investors also reassessed the cost and expected returns of the rapid buildout of AI computing infrastructure.

Some investors are weighing whether the Democratic victories in Tuesday’s U.S. midterm elections could make data-centre approvals more difficult in places where candidates campaigned against expansion. That is a market concern about possible future policy, not evidence that projects have been cancelled. Reuters also reported a broad fall in global shares, while AP described losses in South Korea and Japan alongside the U.S. decline.

A correction measures the fall, not what comes next

Market convention calls a decline of 10% or more from a recent high a correction; a 20% fall is commonly called a bear market. The label marks the size of a drawdown, not a forecast of further losses or a verdict on whether AI investment will pay off.

The change does show how quickly expectations can shift when several risks arrive together: financing costs, doubts about returns on large infrastructure spending, company results and uncertainty over permitting. None of those factors alone establishes why every investor sold or how much future data-centre capacity will be built. The record remains a price signal from markets, not a measure of completed investment or a settled outlook for the wider economy.
