The decline in Ford's stock price can be attributed to two main factors: the overall market weakness triggered by the release of March inflation data, and the negative perception associated with the recall of 42,652 vehicles. The market's reaction to inflation data typically affects stocks broadly, indicating a macroeconomic influence. Meanwhile, vehicle recalls can lead to concerns about product quality and potential financial impacts due to repair costs and damage to brand reputation. Both factors are likely contributing to the short-term negative sentiment towards Ford's stock.
