On Tuesday, the French CAC 40 index rose 0.8% to 8034 points, rebounding from a decline in the previous session, with investors primarily focused on corporate earnings and news. Vicat shares rose 2.9% after the company reported first-quarter sales growth and reiterated its 2026 outlook. Saint-Gobain shares also rose 0.3% on plans to sell part of its distribution business. Other gainers included LVMH (0.7%), Schneider Electric (1.3%), Orange (2.6%), and Capgemini (1%). In contrast, Sanofi shares fell 4%, hitting their lowest level since March 2020, after the company announced a $294 million investment plan for artificial intelligence expansion. Beneteau shares also fell 2.4% despite first-quarter revenue growth, as its outlook was dampened by slower order growth related to uncertainty in the Middle East. Despite this, reports that the US military repelled an Iranian attack while escorting two US-flagged ships through the Strait of Hormuz, coupled with reports of a drone strike on the UAE port of Fujairah, have left investors uneasy. This renewed escalation of tensions could undermine the fragile ceasefire agreement between the US and Iran.
