AI bubble fears trigger sharp selloff in European chip stocks

European semiconductor stocks plunged on October 15, with ASM down 8.5%, Besi down 6.1%, and ASML down 5.2%, as investor concerns over an AI-driven bubble intensified. The selloff reflects growing skepticism about the sustainability of AI-related capital expenditure and valuations. This marks a notable shift in sentiment after a prolonged rally in chip stocks.
