Germany's DAX reversed course to close about 0.4% up at 24,049 on Wednesday, as European markets followed US peers, as concerns over lofty AI valuations eased. Meanwhile, the earnings season continued to be closely watched. BMW shares jumped more than 6%, also lifting the stocks of other automakers, after reporting higher Q3 earnings and saying it was on track to meet its full-year targets. On the opposite side, Siemens Healthineers was the top loser, slipping 8.6%, after the company posted a fall in fourth-quarter profit that undershot market expectations, blaming the impact of US tariffs. Fresenius SE moved into negative territory, falling about 1%, after reporting a mixed set of Q3 results, with a beat on operating earnings but a slight miss on revenue.
