Euro Stoxx 50 closes at 6,170.49, down 0.98 percent on AI concerns

The Euro Stoxx 50 ended Friday, November 6, 2026, at 6,170.49 points. The blue-chip eurozone index fell 61.05 points, or 0.98 percent, from Thursday's close of 6,231.54, according to Dow Jones Market Data and FactSet, published by Morningstar. The decline marked the index's largest one-day percentage fall since October 30, while the benchmark remained 0.64 percent higher for the week.

Global technology sell-off reaches Europe

Friday's losses followed a sharp retreat in US technology shares on Thursday and steep declines across Asian markets. Investors were concerned that the Democratic victory in the US midterm elections could lead to tighter oversight of artificial intelligence and slow the expansion of data centers. Questions about the returns on large AI investments, high valuations and debt-funded spending added to the pressure.

Reuters reported that losses were broad-based in early European trading and said the region's smaller exposure to major AI stocks had limited the damage relative to Asia and Wall Street. The news agency also cited concerns that a slowdown in AI infrastructure spending could weigh on the wider economy.

Weekly gain survives Friday decline

Friday's setback extended the Euro Stoxx 50's decline to a second consecutive trading day. Over the past two sessions, the index lost 95.22 points, or 1.52 percent. It nevertheless advanced for the second week in a row and remained 6.55 percent below its record close of 6,551.22 reached on August 11.

For investors, the session underlined the sensitivity of European equities to developments in US technology markets and to changing expectations for AI investment. The weekly gain provides a broader context, but the immediate direction remained dominated by risk reduction and uncertainty over future regulation and spending.
