European equity markets have experienced a significant resurgence around November 20, 2025, with major indices climbing as robust company results, particularly from the technology sector, have effectively soothed widespread concerns about an "AI bubble." This upturn signals renewed investor confidence in the region's economic stability and the tangible value being generated by artificial intelligence, marking a pivotal moment after a period of market apprehension.

The rebound, which saw the pan-European STOXX 600 index gain 1% and the European technology index climb 1.8% on November 20, was largely catalyzed by stellar earnings reports. These strong performances have provided a much-needed antidote to the growing skepticism surrounding the sustainability of AI-driven valuations, suggesting that the industry's growth is grounded in solid fundamentals rather than mere speculation.

Detailed Coverage: A Market Transformed by Performance

The recent European stock market rally around November 20, 2025, was a direct response to a pivotal shift in investor sentiment, largely orchestrated by stronger-than-expected corporate earnings. This rebound followed a period of pronounced anxiety regarding an "AI bubble," which had seen European equities, particularly tech stocks, experience notable declines.

In the days leading up to the rebound, specifically between November 15 and 19, 2025, the market was gripped by a "risk-off" mood. The STOXX Europe 600 index and other major bourses repeatedly fell, with investors citing "AI bubble fears," weak economic data from China, and diminishing prospects of immediate U.S. Federal Reserve rate cuts. Tech giants like ASML Holding N.V. (AMS: ASML), SAP SE (ETR: SAP), Infineon Technologies (ETR: IFX), and Prosus (AMS: PRX) all saw their shares dip, reflecting widespread doubts about AI valuations. Volatility gauges jumped, underscoring "higher anxiety throughout the market."

The turning point arrived with the post-market close announcement on November 19, 2025, from the U.S. chipmaker Nvidia (NASDAQ: NVDA). Nvidia reported record revenue of $57 billion for its fiscal third quarter, a staggering 62% year-on-year increase, and projected an even more optimistic fourth-quarter revenue of $65 billion, significantly exceeding Wall Street's expectations. Crucially, Nvidia's CEO, Jensen Huang, directly addressed the "AI bubble" fears, stating that the "AI ecosystem is scaling fast" and that "compute demand keeps accelerating and compounding across training and inference, each growing exponentially."

This bullish outlook from a key AI industry player triggered an immediate "relief rally" across global markets, profoundly impacting European stocks. On November 20, 2025, several European companies with direct or indirect exposure to the AI and technology sectors saw substantial gains:

• ASML Holding N.V. (AMS: ASML) and Infineon Technologies (ETR: IFX) both rose 2.8%.
