Introduction
The Nasdaq Composite suffered its worst day in 19 months on Thursday, 5 November 2026, plunging 5.5 per cent as fears of tougher AI regulation sent chip stocks tumbling — two days after the Democrats swept both houses of the US Congress in the midterm elections.
What Happened?
The tech-heavy Nasdaq Composite fell 1,421.52 points, or 5.52 per cent, to close at 24,315.00 on Thursday — its steepest single-day fall since April 2025, when President Donald Trump's tariff announcement rattled markets. It left the index 11.9 per cent below its record closing high of 27,599.89, reached on 6 October 2026. A fall of 10 per cent or more from a recent peak is widely regarded as a correction, so Thursday's close confirmed the Nasdaq is in correction territory — its second of 2026, after one in March.
The sell-off was broad: the S&P 500 dropped 4.36 per cent to 7,353.73 and the Dow Jones Industrial Average fell 3.44 per cent to 51,523.06, giving all three benchmarks their worst session since April 2025. About $3 trillion in market value was wiped from S&P 500 companies, and the VIX fear gauge jumped nearly 70 per cent to 28.18.
Chip and AI infrastructure stocks bore the brunt: Nvidia fell 9.26 per cent, AMD 17.26 per cent, Micron 17.46 per cent and SanDisk 22.26 per cent, while Tesla dropped 10.86 per cent. AppLovin bucked the trend, surging 31 per cent after strong results and an expanded share buyback.
Why Does This Matter?
The trigger was politics as much as economics. Democrats won control of both the House and the Senate in Tuesday's midterm elections, and investors fear the new Congress will tighten rules on AI and slow the data-centre building boom behind the market's rally. That matters because the AI trade has carried Wall Street through 2026: the Nasdaq's surge to its October record was built on heavy spending by chipmakers, cloud providers and data-centre operators. Thursday's rout was investors repricing that bet, asking whether the returns on trillions of dollars of AI investment will arrive as fast as the spending. Weak results from chipmaker Qualcomm added to the doubts. Indian IT stocks track Nasdaq sentiment closely, and a prolonged US correction would weigh on the foreign inflows behind Mumbai's recent rally.
Important Details
Nasdaq Composite: Down 5.52% (1,421.52 points) to 24,315.00 on 5 November 2026; 11.9% below its record close of 27,599.89 on 6 October 2026. Biggest one-day fall in 19 months.
Worst-hit stocks: SanDisk -22.26%, Micron -17.46%, AMD -17.26%, CoreWeave -15.30%, Tesla -10.86%, Nvidia -9.26%. The Philadelphia Semiconductor Index fell 12.2%.
India on Thursday: The Sensex surged 2,008.61 points (2.6%) to 79,310.01 and the Nifty gained 576 points (2.4%) to 24,536.60 — a sixth straight session of gains.
Asia on Friday: South Korea's Kospi plunged more than 8%, triggering a 20-minute circuit-breaker halt, and Japan's Nikkei fell 6.23%, entering bear-market territory.
Background and Context
The Nasdaq has swung sharply through 2026: it closed in correction in March, recovered to record highs in early June, nearly slipped into correction again in late July, then set fresh highs in September and October as AI spending accelerated. Thursday's fall erased the gains from Wednesday's post-election rally. For months, analysts have questioned whether the vast sums being poured into AI chips, data centres and power capacity will generate matching profits; what changed this week was the political backdrop, with a Democrat-controlled Congress now expected to scrutinise AI companies and data-centre construction.
What Happens Next?
Attention turns to the US October jobs report, due at 8:30 am Eastern Time on Friday, 6 November. Economists expect about 65,000 new jobs and an unemployment rate steady at 4.2 per cent; a weak report could deepen the sell-off, a strong one could steady nerves. In India, GIFT Nifty was trading around 24,424 on Friday morning, down about 175 points, signalling a weak open after the Sensex and Nifty's six-session rally.
What Readers Should Know
A correction is a fall of 10 per cent or more from a recent high — not the same as a bear market, which requires a 20 per cent drop. The Nasdaq is still up 4.6 per cent in 2026 despite Thursday's rout. For Indian investors, the direct exposure is limited: domestic markets rallied strongly on Thursday and have been cushioned by lower crude prices and foreign inflows. Watch the US jobs report and the opening in Mumbai rather than panic.
