Semiconductor stocks are experiencing a significant rally as the market reassesses fears of a slowdown in the AI sector that were triggered by the recent U.S. midterm election results. The sharp downturn late last week is now being viewed by some investors as a buying opportunity. This rebound is occurring despite negative news surrounding industry leader Nvidia, whose stock is under pressure due to a board investigation involving its CEO. Strength in other major chipmakers, particularly Taiwan Semiconductor Manufacturing Co. (TSMC), is helping to fuel the broader sector's gains.
