All three major U.S. stock market indices closed the day in positive territory, with the technology sector leading the way with particularly impressive gains. Notably, Apple's share price surged by an astonishing 4.24% in a single day, pushing its market value up by $138.3 billion. Recently, U.S. President Trump announced plans to impose significant tariffs on imported chips and semiconductors, but granted exemptions to companies with domestic production facilities, including NVIDIA and Apple. Leveraging this opportunity, Apple announced that it will invest $600 billion in the U.S. over the next four years, aiming to establish a comprehensive chip manufacturing supply chain and gradually reduce its reliance on overseas sources. This strategic move underscores Apple's dedication to the U.S. domestic manufacturing sector and adds a pivotal new dimension to its global supply chain strategy.
