On July 8, United Microelectronics fell 3.32% overnight, trading at $23.07 per share, with turnover of $477,600.

The decline extends the prior trading session's weakness. On July 7, the semiconductor sector saw broad-based selling, with Intel falling 7.98%, Advanced Micro Devices dropping 7.12%, and Micron Technology declining 6.3%, dragging UMC down 6% during regular hours. The systemic sector pressure continued into overnight trading.

While UMC reported solid June consolidated revenue of NT$23.125 billion, representing a 22.85% year-over-year increase, and first-half cumulative revenue grew 11.28% to NT$129.77 billion, this positive data had already been fully priced in during the July 6 session when shares rallied over 4.6%. With no incremental catalysts emerging, the stock continues to retrace those gains under sustained selling pressure.
