On June 3, UMC fell 5.65% in pre-market trading, trading at approximately $20.98/share, with trading volume of $388,600, extending its recent correction trend.

On the news front, UMC's TTM price-to-earnings ratio has risen to 36.7x, far exceeding its five-year median of 11.8x. Following a significant year-to-date rally fueled by strong Q1 results and pricing power announcements, the stock faces sustained valuation compression. Although the company previously reported Q1 net profit surging 108% year-over-year to NT$16.17 billion and announced selective price hikes for the second half with broader adjustments planned for 2027, the rapid share price appreciation has accumulated substantial valuation risk that is now being unwound.

Within the Semiconductors sector, sentiment remains subdued. Among individual stocks, Micron Technology down 0.25%, NVIDIA down 0.23%, Marvell Technology up 13.57%, Broadcom up 3.12%, Advanced Micro Devices down 1.06%.
