Tech Stocks Plunge as Nasdaq Enters Correction

U.S. technology stocks suffered a massive sell-off on Thursday, sending the Nasdaq Composite down 5.52% to close at 24,315.00 and pushing the benchmark into a technical correction. Wall Street tumbled as investors evaluated emerging regulatory risks surrounding data centers following the Democratic sweep of Congress, which erased expectations that a divided federal government would shield artificial intelligence expansion. The decline pulled down all major market indices, wiped out more than $1 trillion in combined market capitalization from seven top tech companies, and triggered the steepest single-day percentage drops for major benchmarks since April 2025.

How the major stock market indices performed

Thursday's drop was widespread, with all 11 sectors of the S&P 500 ending lower. To understand how the stock market functions during high-volatility events, investors look at broader index shifts and volatility gauges across sectors. The day's key figures include:

• Nasdaq Composite: Dropped 5.52% to 24,315.00, marking a technical correction of more than 10% from its recent high. The Nasdaq 100 declined 6.36% to close at 26,629.81.
• S&P 500: Fell 4.36% to end at 7,353.73.
• Dow Jones Industrial Average: Dropped 1,833.06 points, or 3.44%, to close at 51,523.06.
• Russell 2000: The small-cap index fell 4.45% to 2,729.89.
• Sector Performance: Information Technology fell 7.30%, its worst single-day performance since March 16, 2020. The Technology Select Sector SPDR ETF (XLK) plunged 8.04%.
• Market Breadth and Volatility: Declining stocks beat advancing issues on the NYSE by nearly 6:1. The CBOE Volatility Index (VIX) jumped 11.57 points to 28.18, its highest level since March 31 and its largest single-day gain since April 4, 2025.

The $1 trillion rout in semiconductor and mega-cap tech stocks

Semiconductor manufacturers and artificial intelligence infrastructure firms took the brunt of Thursday's rout. The Philadelphia Semiconductor Index sank about 12%, recording its second-largest single-day decline on record. Intraday trading saw SanDisk drop approximately 22%.

NVIDIA led the losses among mega-cap technology firms, plunging more than 9% and wiping out over $440 billion in market value. The fall brought NVIDIA's year-to-date performance to a decline of approximately 2.6%, turning its performance negative for the year. Both Micron and AMD stock dropped about 17%. CoreWeave fell around 10%, while GE Vernova retreated 7.5%. Meanwhile, mega-cap peers Apple stock and Microsoft pulled back alongside the broader market after setting all-time highs on Wednesday.

What the sell-off means for investors and everyday consumers

For everyday retail investors and retirement savers, a $1 trillion loss across leading technology stocks serves as a sharp reminder of concentration risk in market cap-weighted index funds. Because companies like NVIDIA, Microsoft, and Apple make up significant portions of standard S&P 500 funds, severe drops in the tech sector directly pull down broad 401(k) balances even when non-tech sectors experience smaller losses.

For consumers and corporate buyers, the sell-off reflects growing political and regulatory scrutiny over data center power consumption and AI infrastructure investment. If legislative hurdles slow down data center buildouts, hardware supply constraints could shift, potentially altering software pricing and infrastructure investment cycles for enterprise users.

Divergence in earnings and economic indicators

Despite the broader daytime market drop, several corporate earnings reports created sharp price swings in after-hours trading:

• Airbnb: Posted Q3 revenue of $4.87 billion (exceeding the expected $4.75 billion) and earnings per share of $3.16 (above the $2.85 forecast). The company raised full-year growth guidance to high double digits and authorized a $12 billion buyback, driving shares up approximately 11% to $188.89 after hours.
• Cloudflare: Reported Q3 revenue of $782.5 million and issued Q4 revenue guidance of $845 million to $846 million (beating expected $798 million), jumping about 14% after hours to $279.
• JFrog: Raised full-year outlook and rose about 25% after hours.
• DraftKings & Atlassian: DraftKings fell about 22% after hours after missing Q3 earnings and revenue estimates, while Atlassian dropped over 15% following a lowered data center revenue growth outlook. Affirm fell about 11% and Axon dropped roughly 13% after hours.

On the economic front, weekly initial jobless claims dropped by 6,000 to 189,000, lower than the estimated 197,000. U.S. Treasury yields eased, with the 10-year yield falling more than 5 basis points to 4.839% and the 2-year yield dropping more than 11 basis points to 4.466%. Energy prices jumped following tanker attacks, with WTI crude gaining 2.7% to settle at $90.52 per barrel and Brent crude advancing 3.8% to $98.29 per barrel.

What to watch next

Market participants are focused on the upcoming October U.S. Non-Farm Payrolls report. Economists surveyed by Dow Jones expect an addition of 59,000 jobs with the unemployment rate remaining at 4.2%, following September's lower gain of 29,000 jobs.

Central bank expectations are also adjusting rapidly. CME FedWatch data shows pricing for approximately a 70% chance of a 25-basis-point interest rate hike at the Federal Reserve's December 9 meeting. However, following Thursday's equity tumble, several rate traders began pricing in a delay for the next rate hike until March of next year.
