Shares of Stellantis and Aston Martin have dropped sharply following multiple profit warnings attributed to challenges in the global car industry, particularly due to increased competition from Chinese automakers and a general market downturn. Stellantis, the maker of Chrysler and Jeep, has announced plans to slash its U.S. inventory by 100,000 vehicles by early 2025, reflecting its struggle to cope with weak demand and rising production costs. The company has revised its financial forecasts downward for 2024, with expectations of a significant decline in profit margins and free cash flow. This development comes shortly after Volkswagen also issued a profit warning, causing the European auto sector to lose approximately $10 billion in market value. As the automotive landscape becomes increasingly competitive and challenging, Stellantis appears to be navigating through a particularly difficult period.
