European equities ended Thursday, 5 November 2026, on a mixed-to-negative note. A sharp sell-off in semiconductor stocks and a steep fall in defence shares outweighed gains in selected French and Spanish equities, as investors reassessed the outlook for artificial intelligence investment, corporate earnings and geopolitical risk.
◉ The STOXX Europe 600 fell 0.38% to 654.87, retreating from near-record territory.
◉ European technology shares dropped 3.2%, with ASML, Infineon and other chipmakers among the session’s biggest losers.
◉ Stocks of Rheinmetall plunged 16.1% after another reduction to its 2026 sales outlook, weighing on the defence sector.

Semiconductor Sell-Off Leads the Decline
Technology was the weakest major European sector, falling approximately 3.2% to its lowest level in nearly two months. The decline reflected broader pressure on global technology shares as investors reconsidered the scale and sustainability of investment in artificial intelligence infrastructure.
The sharpest losses were concentrated among semiconductor and equipment companies:
- Soitec: -16.7%
- Siltronic: -12.3%
- Aixtron: -9.8%
- Infineon: -8.5%
- ASML: -6.6%
The concern is not necessarily that demand for AI infrastructure is disappearing. Rather, investors are questioning whether tighter scrutiny of data-centre construction and AI development in the United States could affect the pace of future investment. Existing orders and strong infrastructure spending remain important counterweights to that uncertainty. Reuters+1
Defence Stocks Face a Reality Check
Defence shares also weighed heavily on European markets. The sector declined approximately 2.6%, with Germany’s Rheinmetall at the centre of the sell-off.
The company fell 16.1% after cutting its 2026 sales forecast for the second time in three months. Delays affecting major contracts and slower ammunition deliveries have raised questions about how quickly the company can convert strong defence demand into reported revenue.
The reaction highlights a distinction increasingly important to investors: long-term European defence spending may remain structurally strong, but company valuations also depend on execution, production capacity and delivery schedules.
Earnings Provide Selective Support
Corporate results helped prevent a broader decline across all European sectors.
Air France-KLM advanced approximately 12% after reporting third-quarter operating results that exceeded expectations. Renewable energy company Ørsted gained 3.5%, supported by its results.
Mining shares also benefited from stronger metals prices, providing some support to the wider market. These gains, however, were not sufficient to offset the pressure from technology and defence stocks. Reuters+1
Bank of England and Oil Add to Market Uncertainty
The UK market faced an additional monetary-policy development. The Bank of England raised interest rates for the first time in more than three years and indicated that another increase could be necessary if the US-Iran conflict continues to place pressure on energy prices.
Oil also moved higher during Thursday’s session, with Brent crude gaining more than 2% as investors reassessed geopolitical risks surrounding Iran. For European economies, which depend heavily on imported energy, renewed increases in crude prices can complicate the inflation outlook and the path of monetary policy. Reuters+1
The Bigger Picture
Thursday’s European close exposed a market increasingly sensitive to the quality and sustainability of corporate growth. Semiconductor companies remain central to the AI investment cycle, but investors are demanding greater clarity on future spending. Defence companies continue to operate in a strategically important industry, yet forecast reductions and delivery delays can trigger substantial valuation adjustments.
The mixed performance across national indices also shows that the session was not a uniform retreat from European equities. Earnings and sector-specific developments continued to create opportunities for individual companies even as the broader benchmark moved lower.
The next test for European markets will be whether technology shares stabilise, corporate earnings continue to support valuations and energy prices remain contained enough to prevent additional inflation pressure.
