AI Confidence Crisis Weighs on European Markets!

European stock markets faced sharp pressure during Thursday’s trading session (October 22, 2026), mirroring a wave of sell-offs across global equity markets. The STOXX 50 index slumped 1.5%, hitting its lowest level since mid-June, while the STOXX 600 fell 0.9%. This decline was triggered by investor disappointment regarding the financial results of several major U.S. technology firms, which reignited concerns over the high valuations of stocks linked to artificial intelligence (AI).

Market pressure intensified as global oil prices continued to climb following fresh attacks on facilities in Saudi Arabia. Surging energy costs have fueled concerns regarding corporate operating expenses and the risk of global inflation. Should price pressures persist, central banks may be compelled to maintain a restrictive interest-rate policy for longer—a scenario that could stifle economic growth and diminish the appeal of equities.

On the corporate front, shares of Hermes plummeted 6.6% after the company reported zero sales growth in the region that includes China. Roche shares dipped 1.3% despite posting sales that beat expectations, while Thales fell 1.7% even after raising its annual performance forecast. Barclays also edged down 0.2%, despite a 12% year-on-year increase in profit. These movements underscore a cautious investor sentiment, even as some companies reported relatively positive results.

Amid the broader market weakness, shares of SAP remained relatively stable after the company lifted its annual performance outlook, while Nestle rose 2.3% on the back of solid third-quarter sales growth. Looking ahead, European stock markets are expected to remain sensitive to corporate earnings reports, oil price fluctuations, and the trajectory of global interest rates. If concerns regarding AI valuations continue to mount and energy prices remain high, selling pressure in European markets could potentially persist.
