United Microelectronics is trading 4% up at $21.12 as part of a broad semiconductor rebound driven by renewed AI optimism and sector bargain-hunting following last week’s sharp selloff.

  • The move follows recent volatility in chip names and improving sentiment regarding global AI infrastructure demand.
  • While no new stock-specific news was released this morning, investors remain focused on previously reported silicon photonics progress and expected Q2 strength.
