European shares slip as tech selloff bites, Zalando slides

European markets retreated from record highs Friday, with tech stocks mirroring global weakness. Zalando shares plunged after a German probe into its accounts, impacting the retail sector. Investors grappled with AI's uncertain impact on tech, while chipmakers saw declines. Despite the dip, the STOXX 600 managed modest weekly gains, buoyed by easing oil concerns and Europe's lighter tech exposure.
