September 10, 2026 in numbers
Alstom SA (ISIN FR0010220475) closed at EUR 15.50 on Euronext Paris on September 10, 2026, down 2.21% from the previous session’s close of EUR 15.85, according to data from Le Figaro’s market overview. Over the day the stock moved in a range between an intraday high of EUR 15.99 and the low and closing level of EUR 15.50, indicating that selling pressure dominated into the finish.
Trading data from Le Figaro show that Alstom opened the session at EUR 15.90, slipped through most of the day, and ultimately settled at the bottom of its trading band, with volume consistent with recent sessions though not flagged as exceptional.
The broader CAC All-Share Index, which includes Alstom among its constituents, recorded a previous close of 9,314.34 points in the prior session per Euronext index data, providing a benchmark for French equities around the time Alstom’s shares lost ground.
Operational developments and today’s focus
On September 10, 2026, Alstom announced that it had begun dynamic testing of the first Line 7 train for the Santiago Metro, highlighting progress on a major Latin American transport project that aims to improve mobility for 1.6 million people and expand access to sustainable public transport across Santiago, according to Alstom. While the testing news came alongside the recent market weakness, trading data did not indicate an immediate sharp reaction tied solely to this announcement.
Heading into today’s session on September 11, 2026, investors can monitor how Alstom’s stock trades in the context of its latest operational milestone in Santiago and the recent pullback in the share price, as well as broader movements in French equity indices such as the CAC All-Share Index documented by Euronext.
