Carrefour SA was up 10.6% after Canadian convenience-store operator Alimentation Couche-Tard Inc said it had approached Europe’s biggest retailer to discuss a combination. The stock topped gains on Paris’ CAC 40, which was up 0.2%, while shares in French retailer Casino jumped 6.4%. Another big gainer was Spanish telecom company Telefonica , which rose over 8% after it agreed to sell its mobile phone masts in Europe and Latin America to U.S.-based telecom infrastructure operator American Towers for 7.7 billion euros ($9.41 billion) in cash. However, the pan-European STOXX 600 index rose just 0.1%, as utilities were a drag after Orsted slumped 7.5% on warning a return to more normal wind speeds this year would hit operating earnings. The German DAX remained muted as Health Minister Jens Spahn said the country will not be able to lift all restrictions imposed to curb the spread of the coronavirus at the beginning of February.
