On the final trading day of May, both the STOXX 50 and STOXX 600 indices hovered near stability, as investors considered the ongoing uncertainty of the US trade war. Notably, a federal appeals court temporarily reinstated President Donald Trump’s tariffs, following a trade court's previous ruling that he had overstepped his authority. Meanwhile, US Treasury Secretary Scott Bessent stated that trade negotiations with China were experiencing a "bit of a stall." Among the sectors, real estate showed strong performance, while mining and technology sectors underperformed. In corporate news, Sanofi's shares declined by over 5%. Despite the day's subdued results, both major European indices are positioned to close the month with gains of approximately 4%, marking their most substantial monthly increase since January.
