United Microelectronics is trading at $14.00, down 13.14%, amid a broader semiconductor selloff as investors weigh whether tighter data-center rules could slow AI infrastructure construction.
- Reuters reported on November 5 that chip stocks remained under pressure, citing those concerns.
- October sales were up 18.33% year over year; available news does not point to a negative company-specific announcement driving the decline.
- The move aligns with weakness across semiconductor markets, including Asian chip shares.
