On June 22, United Microelectronics rose 3.2% overnight, trading at $24.85/share, with turnover of $1.2583 million, extending its recent rebound momentum.

On the news front, UMC's embedded Deep Trench Capacitor (DTC) technology has successfully entered Qualcomm's supply chain and commenced shipments. This breakthrough is compounded by robust Q1 results showing net profit surging 108% year-over-year to NT$16.17 billion, along with confirmed selective price hikes of approximately 10% planned for the second half. The stock had previously pulled back over 15% on elevated valuation concerns, and these multiple positive catalysts are now converging to attract capital inflows.

Within the Semiconductors sector, performance was mixed. Among individual stocks, Intel up 2.62%, Micron Technology up 0.64%, Marvell Technology down 0.28%, Advanced Micro Devices down 0.87%, NVIDIA down 1.13%.
