European stocks extended their gains for a third consecutive session on Wednesday, with the STOXX 50 rising 0.4% and the STOXX 600 up 0.2%, as corporate earnings continued to dominate market sentiment. Siemens Energy advanced 1.8% after reporting a record quarterly order intake, while Fresenius edged up 0.2% following an upgrade to its revenue outlook. Zalando climbed 1.7% after lifting its full-year guidance, and Banco BPM gained 1.4% after beating net profit expectations. On the downside, Novo Nordisk shares were little changed despite a rise in operating profit that came in below forecasts. Glencore dropped 3.7% after reporting a 14% decline in first-half profit, while Commerzbank slipped 1% following a profit drop - though the bank did raise its full-year outlook. In addition, investors remain focused on trade policy developments, with US President Trump signaling plans to announce new tariffs on semiconductors and chips as early as next week.
