The Eurozone's STOXX 50 rose 0.2% to 5,670 and the pan-European STOXX 600 rose 0.3% to 572. Industrial giants and auto producers led the gains in the session to rebound from their losses yesterday, with Schneider Electric and Wolters Kluwer advancing between 2% and 1.5%. In the meantime, BMW surged close to 7% after posting improved margins despite dealing with tariff uncertainties in the third quarter, lifting shares of Mercedes Benz, Volkswagen, and Stellantis by 2% to 4%. On the other hand, ASML dropped 1% amid the pessimistic earnings calls from AMD and Super Micro Computer. Also, Novo Nordisk fell 3.5% after the drugmaker trimmed its growth outlook for its Ozempic obesity and diabetes treatments.
