The CAC 40 fell 0.3% to close at 8,480 on Monday, weighed down by losses in the luxury and pharmaceutical sectors.

In healthcare, Sanofi fell 1.7%.
Industrials traded mixed, with Schneider Electric down 0.6% and Air Liquide losing 1.5%, while Airbus rose 1.6%, Stellantis gained 2%, and Thales advanced 1.2% after agreeing to acquire a stake in Exail Technologies.
Vinci fell 2.1% after France's construction PMI declined to 38.2 in June from 39.6 in May, remaining deep in contraction territory and signaling that the sector has now been shrinking for four consecutive years.
Meanwhile, financial stocks outperformed as lower oil prices eased inflation concerns and reinforced expectations of a more dovish ECB, with BNP Paribas up 0.9% and AXA gaining 1%.
