On July 2, United Microelectronics declined 3.07% in regular trading, trading at $24.895/share, with turnover of $129 million.

On the news front, the U.S. semiconductor sector faced heavy selling pressure, with the Philadelphia Semiconductor Index plunging over 6%. Micron Technology and SanDisk fell more than 10%, Intel dropped over 9%, while TSMC and AMD declined nearly 7%, as systematic selling pressure spread across the sector.

United Microelectronics had previously surged on rumors of a collaboration with Intel to co-develop 3nm and 12nm process technologies, as well as expectations surrounding a global semiconductor price hike cycle. However, the company issued a statement on the Taiwan Stock Exchange noting it does not comment on speculative reports or market rumors. Profit-taking pressure from the prior rally, combined with broad industry weakness, has continued to weigh on the stock, which had already fallen over 5% in the previous trading session.
