Advanced Energy is trading at $188.04, down 11.12%, amid semiconductor-sector pressure.
- Semiconductor shares broadly fell amid concerns tighter AI oversight could slow data-center construction; Qualcomm’s weak handset-chip outlook added to sector losses.
- Broader weakness included the Nasdaq down 3.68%.
- Advanced Energy’s November 2 earnings beat and bullish Q4 outlook do not appear to explain the decline; no company-specific negative catalyst was identified.
