Shares of computer hard-drive manufacturer Western Digital (NASDAQ: WDC) rose 7% today. The surge follows comments from Trump Commerce Secretary Howard Lutnick, who told The Wall Street Journal that the Trump administration "is not in favor" of Apple buying high-bandwidth memory (HBM) from Chinese manufacturers Yangtze Memory Technologies and CXMT. Instead, the administration prefers Apple to source from companies reshoring semiconductor manufacturing to the United States. While Western Digital does not produce HBM, its hard disk drives offer an alternative for computer memory, which is in high demand for data centers and AI inference functions. Investors are anticipating stronger demand for Western Digital's products as obtaining HBM supply becomes more challenging and expensive.
