ChipMOS Technologies is exploding higher today, reaching a fresh 52-week high as investor sentiment remains buoyed by the company's strategic pivot toward memory packaging and testing. This segment now accounts for approximately 51 percent of total revenue, positioning the firm to capitalize on the surging demand for memory-related semiconductor infrastructure. This momentum follows a strong start to the month, where the stock showed early signs of strength by gapping up during the October 2 trading session.
