On July 7, United Microelectronics (UMC) fell 7.24% in pre-market trading, trading at $24.68/share, with turnover of $158,900.

The decline came amid broad weakness across the semiconductor sector. Among peers, Micron Technology dropped 5.27%, Intel fell 3.12%, Advanced Micro Devices declined 2.91%, Broadcom slid 1.38%, and NVIDIA dipped 0.75%, reflecting significant sector-wide selling pressure.

Notably, UMC had rallied approximately 4.65% during the prior trading session on July 6, buoyed by strong June revenue data showing a 22.85% year-over-year increase to NT$23.12 billion, along with a broader semiconductor rebound following the Philadelphia Semiconductor Index's 6%-plus plunge. The current pre-market pullback erases those gains as sector headwinds resume. UMC is a leading global semiconductor foundry providing wafer fabrication services, with its next earnings report scheduled for July 29.
