Despite the possibility of a market rebound on Tuesday following a tough three days, Wall Street is still grappling with evaluating the potential impact of tariffs on American corporations. Retail giant Walmart faces significant profit risks due to potential tariffs, according to analyst Greg Melich. If tariffs on China and the rest of the world are increased, Walmart's earnings per share could experience substantial pressure. Trump's imposition of tariffs on various countries, including key trading partners of large retailers like Walmart and Target, poses challenges. The uncertainty surrounding tariffs has led to a drop in Walmart's stock price. The company, along with others, is working on strategies to mitigate the impacts of potential price hikes on consumer goods.
