United Microelectronics is trading at $26.00 (8% up) in pre-market, extending a strong multi-day rally. - Recent catalysts include its Q1 2026 earnings beat and positive coverage of its 14nm FinFET platform. - Further boosting investor sentiment are recent reports of planned selective wafer price increases for H2 2026 and the strategic divestment of its stake in Novatek Microelectronics Corporation, contributing to last week's gains. - The current move appears to be follow-through buying, as no new company-specific news has been reported overnight.
