Stellantis stock hits five-year low after announcement of partial unemployment in October
The multi-brand carmaker (Peugeot, Fiat, Jeep) faces renewed heavy selling pressure on Tuesday, erasing yesterday's gains and breaking through the five-year low. The day is marked by a concrete operational announcement: three French production sites will be temporarily halted in October.
Red lantern of the CAC 40, a new five-year low at €3.87 during the session
Stellantis closed at €3.89, down nearly 4%, marking the largest decline in the CAC 40 at market close. The stock touched €3.87 during the session, thus breaking the previous five-year low record of €3.90 set on Friday, September 25. This unprecedented floor is part of a continuous slide: the stock has lost nearly 17% over one month and more than 22% over the quarter, bringing the decline to over 50% on a year-to-date basis. The €3.97 support level was breached downward during the session and the stock failed to recover it.
Far from its moving averages, it is trading 12.29% below the 20-day MA at €4.43 and 16.44% below the 50-day MA at €4.65. The 200-day MA at €6.30 is nearly 38% above the current price, signaling a deteriorated trend over several months. The RSI at 35, approaching oversold territory without clearly reaching it, reflects selling exhaustion during the week without signaling an imminent reversal. For context, Renault declined 1.29% during the session.
Three French plants halted in October, reasons that differ by site
Today's announcement directly weighs on the session: Stellantis will temporarily suspend production at its Sochaux, Rennes and Mulhouse plants in October. At Sochaux and Rennes, the group lacks batteries to meet strong demand for high-range electric versions. At Mulhouse, the opposite is true: demand is weakening at the end of the Peugeot 308 and 408 life cycle. Two nearly opposite causes producing the same operational result.
These interruptions add to persistent fundamental pressure. When publishing first-half 2026 results on July 30, the Stellantis Pro One commercial vehicles division posted 7% growth, but the group had identified among its risks the variable pace of electrification across markets and the alignment of electric van pricing with diesel, which weighs on margins. According to analyst consensus, the stock trades at approximately 6.8 times expected earnings for the current fiscal year, a low multiple that reflects persistent doubts about the group's trajectory. The next financial publication will be critical in measuring the impact of these production stoppages on second-half volumes.
