The CAC 40 index surged in afternoon trading on Wednesday, reaching a new all-time high of 8,279 points, amid signs that the US government shutdown could end by the week’s close, which would enable the resumption of US economic data releases and ease broader market uncertainties. Further support came from rising expectations of Federal Reserve rate cuts in December, following weaker-than-expected US private employment data. Top gainers included Capgemini (+3.5%), BNP Paribas (+3.5%), Publicis (+3.4%), Renault (+3.0%), and Societe Generale (+3.0%). The luxury sector also performed strongly, with LVMH and Hermes advancing 2.5% and 2.0%, respectively. Veolia added 0.5% after announcing two new contracts and an extension for the operation and maintenance of water services in Australia. In contrast, Edenred plunged as much as 10% after cutting its 2026 profit guidance, citing the impact of new regulations in Brazil.
