The pan-European STOXX 600 index rose 1% in early trading after worries about the fast-spreading Delta variant and slowing economic growth knocked 2.3% off the index in the previous session. Miners led the gains, rising 1.6%, after BHP Group and Anglo American provided upbeat production numbers. Swiss bank UBS gained 4.6% after it posted a 63% jump in second-quarter net profit, helped by a booming wealth management business. Peer Credit Suisse rose 1.8%. Among decliners, Sweden’s AB Volvo fell 3.6% as it warned of further production disruptions and stoppages this year due to chip shortages. Home appliances maker Electrolux tumbled 8.7% after it reported a lower-than-expected second-quarter operating profit and warned global supply chain woes would worsen in coming months.
