The pan-European STOXX 600 index inched up 0.3% in its third session of gains, with miners and travel stocks leading the rise. UK’s commodity-heavy FTSE 100 outperformed as a surge in metals prices lifted shares of companies such as Rio Tinto, Anglo American and BHP. Swiss engineering company ABB rose 3.3% after raising its full-year sales outlook. French advertising group Publicis gained 2.6% as it returned to organic growth for the first time since before the COVID-19 pandemic. Britain’s food delivery company Deliveroo slipped 1.5% even as its quarterly orders more than doubled in its first trading update since its underwhelming market debut last month.
