The CAC 40 fell 0.3% to 8,400 on Monday, trimming gains from the previous week as investors weighed mixed developments surrounding US-Iran diplomatic efforts. While US President Donald Trump renewed threats of military action if Hezbollah continues its attacks on Israel, the US and Iran reportedly made encouraging progress in negotiations, with both sides agreeing on a roadmap aimed at reaching a final agreement within 60 days. Luxury stocks led the declines, with LVMH falling 0.6% and Hermes losing 0.5%. On the upside, STMicroelectronics advanced 2.2% after announcing the launch of the VL53L9, a compact direct Time-of-Flight (dToF) 3D LiDAR all-in-one module designed to deliver high-resolution sensing performance and reinforcing the company's position in advanced sensor technologies.
