ASE Technology Gains 5% as Packaging Rival Amkor Touts “Expanding Customer Commitments”
ASE Technology (ASX) rose 5% after rival Amkor Technology (AMKR) reported record Computing revenue and strong demand, despite missing estimates. Amkor's customers are prepaying for capacity, indicating robust demand for advanced packaging. TSMC may raise CoWoS packaging prices by 20%, suggesting tight supply. ASE reports Q3 earnings this week, with a 148% gain this year.
