European stock markets declined sharply on Friday, November 6, as heavy selling in technology shares followed a substantial overnight decline on Wall Street, where the Nasdaq Composite entered correction territory.
The pan-European STOXX 600 fell as much as 1.6%, marking its steepest daily decline since July and erasing its gains for the week. The index had approached a record high during Thursday’s session before the global technology sell-off reversed market sentiment.
Germany’s DAX declined 1.7%, France’s CAC 40 lost 1.4%, Spain’s IBEX 35 fell 1%, and London’s FTSE 100 retreated 1.5%.
Despite the latest losses, European equities continued to outperform their US counterparts in 2026, with the STOXX 600 maintaining a year-to-date gain of more than 10%, compared with just over 7% for the S&P 500.
Technology Shares Lead European Market Declines
European semiconductor and software companies were among the hardest hit as investors reduced exposure to technology stocks following the sharp decline in US equities.
Dutch semiconductor equipment manufacturer ASML Holding (EU:ASML) fell more than 1%, while technology investment group Prosus (EU:PRX) also declined by over 1%.
French IT services company Capgemini (EU:CAP) dropped 2%, while German enterprise software provider SAP (EU:SAP) lost 0.9%.
The declines reflected concerns that increased regulatory scrutiny of artificial intelligence and large technology companies could affect future investment and earnings growth.
European technology shares had previously benefited from positive corporate earnings and sustained spending on AI infrastructure, but the latest market volatility prompted investors to reassess valuations across the sector.
Nasdaq Enters Correction Territory After 5.52% Plunge
The European sell-off followed one of Wall Street’s sharpest declines in recent months.
The Nasdaq Composite fell 5.52% on Thursday, its largest single-session loss in 19 months.
The decline left the technology-heavy index more than 10% below its October 6 record high, confirming a technical correction.
The S&P 500 also dropped more than 4%, reflecting widespread selling across US equities.
The losses represented Wall Street’s steepest daily decline since the market disruption following President Donald Trump’s “Liberation Day” tariff announcements in April 2025.
The sharp retreat in US technology stocks quickly affected European markets, particularly companies exposed to semiconductor manufacturing, enterprise software and artificial intelligence infrastructure.
US Midterm Elections Raise Concerns Over AI Regulation
Investor sentiment deteriorated following Tuesday’s US midterm elections, which resulted in Democrats securing majorities in both the Senate and the House of Representatives.
The election outcome prompted investors to consider the possibility of tighter antitrust enforcement and increased federal oversight of major technology companies.
Artificial intelligence infrastructure has become a particular area of concern because of the substantial electricity and water requirements associated with large data centres.
Democratic victories in several competitive states also drew attention to growing local opposition to data centre developments.
Investors are assessing whether more restrictive environmental requirements and permitting procedures could delay projects or increase costs for companies investing heavily in AI infrastructure.
Such developments could affect the pace of capital expenditure that has supported strong demand for semiconductors and related technology services.
The resulting uncertainty contributed to selling pressure across both US and European technology stocks.
European Corporate Earnings Provide Support
Despite Friday’s decline, European equities have benefited from a comparatively resilient third-quarter earnings season.
Approximately half of STOXX 600 companies have reported quarterly results, with more than 50% exceeding analysts’ profit expectations.
Companies operating in consumer staples, capital goods and electrification infrastructure have delivered encouraging updates, supporting confidence in corporate profitability.
The results have helped offset concerns surrounding higher transport costs and geopolitical tensions in the Persian Gulf.
European businesses have also benefited from changes in energy prices, particularly the recent sharp decline in crude oil.
Brent crude futures fell approximately 20% during the week, dropping below $100 per barrel.
Lower oil prices could ease cost pressures for energy-intensive manufacturers and support consumer spending by reducing some energy-related expenses.
These developments have provided support to parts of the European market despite continued volatility in technology shares.
STOXX 600 Overtakes S&P 500 in Year-to-Date Performance
European equities have maintained a stronger overall performance than US stocks during 2026, despite the latest market correction.
The STOXX 600 entered the weekend with gains exceeding 10% since the beginning of the year.
By comparison, the S&P 500’s year-to-date advance had narrowed to slightly more than 7% following the recent technology sell-off.
The difference reflects, in part, the contrasting composition of the two markets.
US equity benchmarks have substantial exposure to large technology companies whose valuations depend heavily on expectations for artificial intelligence growth.
European indices have a more diversified sector composition, including financial services, industrial businesses, consumer goods and companies with comparatively value-oriented valuations.
This difference has provided some relative protection during the recent decline in technology shares.
Nevertheless, Friday’s losses demonstrate that European equities remain vulnerable to changes in global investor sentiment, particularly when substantial selling affects major US markets.
Investors Monitor Technology Valuations and Earnings Outlook
The latest decline comes after a volatile week for European markets, characterised by sharp movements in energy prices, changing political expectations in the United States and monetary policy developments in the United Kingdom.
The Bank of England’s first interest-rate increase in three years added another factor for investors to consider alongside corporate earnings and global economic conditions.
Although the STOXX 600 surrendered its weekly gains, its stronger year-to-date performance highlights the relative resilience of European equities.
Investors will continue to assess whether the technology sell-off represents a temporary adjustment in valuations or signals a more sustained change in expectations for artificial intelligence investment.
The direction of European markets will also depend on upcoming corporate earnings, developments in energy prices and the potential effects of changes in US technology regulation.
