The United Auto Workers union has struck a tentative deal with Ford Motor Co., potentially ending a strike that started in mid-September and impacted production at Ford, General Motors Corp., and Stellantis N.V. The strike has negatively affected the stocks of these companies, with Ford and GM seeing a downward trajectory, while Stellantis has traded in a broad range. The strike came at a difficult time for the automakers, who were already dealing with a challenging economy, higher input costs, and a transition to electric vehicle manufacturing.
