Apple's stock took a hit on Tuesday, falling 6.5%, after White House spokeswoman Karoline Leavitt said President Trump believes the iPhone can be made in the United States. This statement quickly attracted the attention and concern of investors, causing Apple to suffer a cumulative loss of up to 23% in the past four trading days.

For context, Apple has long relied on supply chains in places like China for production, and Trump's remarks may suggest a greater emphasis on U.S. manufacturing. However, experts point out that there are huge challenges in completely transferring iPhone production to the United States, including rising costs and insufficient production capacity.

Although some believe that US production will promote employment, in reality, this idea may be difficult to implement if relevant technical and cost issues cannot be effectively resolved. In the future, how Apple adjusts its global supply chain strategy and whether it will be affected by policies will become the focus of market attention.
