European shares fall as worries about AI costs hit technology stocks

European shares fell on Friday as technology stocks sold off worldwide.

The Stoxx 600, a broad European share index, dropped 0.36%, although it still had its strongest month since June.

Results from US companies Amazon and Intel renewed worries about the high cost of AI infrastructure.

European technology shares fell 2.75%, the sector's steepest daily decline since July 7.

Strong company results and faster-than-expected growth in the eurozone offered some support, but the sell-off showed how quickly investor confidence can shift.

Investors also faced higher-than-expected inflation in France and pressure from rising government debt; the sources give no specific next step.
