AI Summary

Summarized by AI from the source below

On Thursday, major U.S. stock indices suffered steep declines amid investor concerns about a slowdown in artificial intelligence development. The tech-heavy Nasdaq Composite dropped more than 5%, entering correction territory alongside the Russell 2000 small-cap index. The Dow Jones Industrial Average fell over 1,800 points, a decline of more than 3%, while the S&P 500 pulled back by more than 4%. These losses erased the gains made in Wednesday's postelection rally.

The Nasdaq Composite experienced its worst single-day decline since April 4, 2025, dropping 5.82%. The S&P 500 recorded its largest daily fall since the same date, declining 5.97%. The Dow also saw its worst day since April 4, 2025, falling more than 2,200 points or 5.5%. The group known as the "Magnificent Seven," led by Nvidia, lost over $1 trillion in combined market capitalization, with Nvidia alone shedding more than $440 billion and falling over 9% to turn negative year-to-date by 2.6%. The CBOE Volatility Index (VIX) increased by 11.57 points, marking its highest level since March 31 and its largest point gain since April 4, 2025.

All 11 sectors of the S&P 500 closed negatively, with the information technology sector down 7.30%, its worst daily performance since March 16, 2020. The Technology Select Sector SPDR Fund (XLK) fell 8.04% on volume three times its 30-day average. A large proportion of stocks in the S&P 500 and Nasdaq-100 were significantly below their 52-week highs, underscoring broad weakness in the market. This matters for investors as the steep declines, particularly in leading tech stocks and indicatives like the VIX spike, signal increased market volatility and risk affecting portfolio valuations.
