On August 4, United Microelectronics rose 5.46% in regular trading, trading at $19.97/share, with turnover of approximately $24.58 million. The stock recovered from the prior session's 7.78% decline as the broader semiconductor sector staged a collective rebound.

On the news front, the semiconductor sector saw broad-based gains, with Intel up 6.59%, Advanced Micro Devices up 5.45%, and Micron Technology up 5.07%, lifting sector sentiment and supporting United Microelectronics' recovery. Additionally, the company's Q2 earnings released on July 29 continue to underpin bullish sentiment — EPS came in at $0.54, beating the consensus estimate of $0.15 by 260%, while revenue of $2.176 billion also exceeded the $2.060 billion estimate. Wafer shipments grew 10.6% quarter-over-quarter with utilization rising to 85%, driven by strong communication and consumer demand. The board also approved approximately $5 billion in capital expenditure for phased capacity expansion at its Singapore and Tainan facilities to capture AI and edge computing opportunities, including silicon photonics production.
