The CAC 40 edged lower to trade around 7,756 on Wednesday, marking its fourth consecutive session of losses, as investors weighed a fresh round of corporate earnings and news, alongside US tariff developments. Renault slumped 16% to its lowest level since February 2024 after issuing a downgrade to its full-year outlook and reporting preliminary first-half results that fell short of expectations. Fellow automaker Stellantis NV also fell 3.9% after announcing it would halt development of its hydrogen fuel-cell technology. Other notable underperformers included Edenred (-2.9%), Kering (-2.8%), and STMicroelectronics (-1.9%). Conversely, Essilor rose 1.1%, Sanofi gained 0.9%, and Publicis added 0.7%, all showing resilience. Meanwhile, trade tensions continued to weigh on market sentiment, following US President Trump's warning that tariffs on pharmaceuticals could be introduced by the end of the month, along with suggestions that levies on semiconductors may follow.
