On July 9, United Microelectronics rose 4.61% overnight, trading at $25.87/share, with turnover of $5,353.16.

On the news front, UMC's Q2 revenue surged nearly 17% year-over-year, reaching a 15-quarter high and providing fundamental support for the stock. The company reported June consolidated revenue of NT$23.125 billion, up 22.85% year-over-year, while first-half cumulative revenue rose 11.28% to NT$129.771 billion, demonstrating robust business momentum.

The current rally also carries characteristics of an oversold rebound. UMC had experienced sharp consecutive declines earlier in the week — falling 6% intraday on July 7 and another 3.32% in after-hours trading — accumulating nearly 9% in losses amid broad semiconductor sector weakness. The subsequent recovery reflects a technical snapback supported by strong revenue fundamentals. Additionally, market expectations surrounding UMC's collaboration with Intel on 3nm and 12nm process technologies, along with a new round of price hikes initiated by nearly 20 global analog and power semiconductor companies, continue to bolster sentiment.
