Alstom stock breaks through its 15.50 € support and falls 26% over one year

The Saint-Ouen-sur-Seine railway manufacturer is declining sharply this Tuesday, in an SBF 120 that is itself in retreat. The stock crosses downward a closely monitored technical threshold, in a market context darkened by anticipations of Federal Reserve rate hikes and soaring oil prices.


Alstom stock breaks through its 15.50 € support and falls 26% over one year

A 15.50 € support breached during the session, against persistent downward pressure

Alstom falls 2% to 15.47 € during the session, after breaking through its 15.50 € support, now exceeded downward. The stock is trading below its MA20 (16.09 €) and MA50 (16.08 €), with a gap of approximately 3.9% below these two averages, which are holding at nearly identical levels and signal a neutral dynamic in the short term. The MA200, at 20.71 €, remains far above, with a gap of more than 25%, illustrating the scale of the downward trend engaged over the long horizon.

The RSI at 45 remains in neutral territory, without a marked signal of selling exhaustion for now. Over the week, the stock loses 5.12%, and over one year, the decline reaches 26.15%. The next identified resistance is located at 16.93 €, representing a gap of approximately 9.4% above the current price.

The macro backdrop weighs on industrial values this Tuesday: the Federal Reserve is widely expected to raise its key rate as soon as Wednesday, and the 10-year Treasury yield has crossed the 5% threshold, at its highest since October 2023. This tightening of global financial conditions accentuates caution on risky assets, including Alstom. On the fundamentals side, recently signed contracts (1.2 billion euros with TransPennine Express in the United Kingdom and 4.7 billion Canadian dollars with VIA Rail Canada in early September) testify to an active order book. When publishing first quarter 2027 results on July 22, 2026, the group had confirmed its outlook for fiscal year 2026/27, with targeted organic growth of approximately 5% and adjusted operating margin expected around 6.5%.

On the basis of expected earnings, the stock is trading at approximately 9.9 times the earnings for the current fiscal year, according to analyst consensus surveyed. Furthermore, net short positions declared stand at 4.48% of capital, distributed among five funds, according to the declarations consulted. This level, although down 0.74 percentage points over thirty days (against 5.22% a month earlier), remains high and reflects persistence of institutional bearish bets on the stock, to be monitored over time.
