On November 18, 2025, US stock markets faced notable declines amid growing apprehension over artificial intelligence valuations and the overall economic outlook. The Dow Jones Industrial Average fell approximately 1.1%, or nearly 500 points, marking its worst three-day performance since April. The S&P 500 and Nasdaq Composite also experienced significant drops, with the Nasdaq pulling back nearly 1.2%. These downturns were influenced by worries about an AI bubble and broader economic concerns, leading to a risk-off sentiment among investors. Additionally, Bitcoin briefly dipped below $90,000, erasing all of its gains for the year, further reflecting market unease.
The technology sector was particularly impacted, with major companies like Amazon, Microsoft, Tesla, Nvidia, and Meta Platforms all experiencing declines of over 2%. Nvidia's stock, for instance, fell by about 2.7% ahead of its third-quarter earnings report, which investors are closely watching to gauge the health of the AI market. The upcoming earnings report is expected to provide insights into Nvidia's performance and the broader AI sector, potentially influencing market sentiment in the coming days. Investors should remain vigilant, monitor upcoming earnings reports, and stay informed about economic indicators to navigate the current market volatility effectively.
