On June 5, United Microelectronics (UMC) fell 3.01% in regular trading, trading at $20.23/share, with trading volume of $133 million, extending a multi-day correction trend.

On the news front, UMC's current TTM price-to-earnings ratio stands at approximately 35.5x, far exceeding its five-year median of 11.8x. Despite the company reporting Q1 net profit surging 108% year-over-year to NT$16.17 billion, with gross margin reaching 29.2%, and announcing selective price hikes of approximately 10% for the second half, the elevated valuation accumulated from its sharp year-to-date rally remains the primary market concern triggering sustained selling pressure.

Meanwhile, the broader semiconductor sector experienced a significant selloff, with Marvell Technology down 8.68%, Advanced Micro Devices down 6.91%, Micron Technology down 6.41%, Broadcom down 4.91%, and NVIDIA down 4.13%, creating a broad-based drag that amplified UMC's decline.
