On August 18, United Microelectronics fell 5.22% in pre-market trading, trading at $18.53/share, with turnover of $2.6155 million. The decline was driven by broad-based weakness across the semiconductor sector, as concerns over AI supply chain valuation corrections and market sentiment volatility weighed on chip stocks.

Within the Semiconductors sector, the selloff was widespread. Micron Technology fell 4.9%, Intel dropped 4.6%, Advanced Micro Devices declined 3.48%, NVIDIA slipped 2.06%, and Broadcom lost 1.96%. The sector-wide retreat reflected investor concerns about AI hardware capital expenditure potentially falling short of expectations, triggering profit-taking after recent gains.

Despite the short-term headwinds, United Microelectronics reported robust operating fundamentals, with July consolidated revenue reaching NT$23.84 billion, up 19% year-over-year, driven by recovering demand in power management and sensor chips. The company's first-half earnings per share came in at NT$4.68, with net profit surging 250% year-over-year. However, the strong results were insufficient to insulate the stock from sector-wide selling pressure.
