description: "On November 5, 2026, the U.S. stock market suffered a brutal, broad-based sell-off that completely erased the previous day's post-midterm election rally, presumably driven by panic in artificial intelligence (AI) and semiconductor stocks.It first got my attention when I received multiple price alerts simultaneously. Seeing so many tickets tickets down make me realised a broad based selloff was happening.Major Index Performance• Nasdaq Composite: Plunged 5.52% (closing at 24,314.99), tumbling into correction territory (more than 10% below its recent record high) and wiping out roughly $2 trillion in market capitalization in a single day.• S&P 500: Dropped 4.36% (closing at 7,353.73), marking its worst single-day drop since April 2025.• Dow Jones Industrial Average: Fell 1,833.06 points or 3.44% (closing at 51,523.06).Possible Key Drivers Behind the Sell-Off• Midterm Election Fallout & AI Regulation Fears: The sharp decline followed the decisive Democratic sweep in the U.S. midterm elections.

Meanwhile, Wall Street's "fear gauge" (the CBOE Volatility Index or VIX) surged sharply.Now let's see how this transmit to the rest of the other markets today..."
