On June 16, United Microelectronics fell 3.23% in regular trading, trading at $22.37/share, with turnover of $18.47 million, extending its recent correction trend.

On the news front, UMC's current TTM price-to-earnings ratio of 35.28x remains far above its five-year median of 11.8x, with the stock having already accumulated over 15% in pullback due to valuation overextension. Meanwhile, the broader semiconductor sector is under pressure, with Intel down 2.06%, NVIDIA down 1.42%, and Marvell Technology down 0.89%, creating a drag through sector sentiment resonance.

Despite solid fundamental support — including Q1 net profit surging 108% year-over-year to NT$16.17 billion, May revenue growing 17.8% YoY, and confirmed selective price hikes of approximately 10% in the second half — short-term valuation correction continues to dominate trading logic as investors digest the prior run-up.
