On July 24, United Microelectronics fell 4.19% in regular trading, trading at $19.84/share, with turnover of $14.93 million.

On the news front, the semiconductor sector weakened broadly as market anxiety over massive AI capital expenditure continued to spread, putting broad pressure on technology stocks. Within the sector, SK hynix fell 4.56%, Micron Technology dropped 4.06%, Intel declined 2.27%, and NVIDIA slipped 0.67%. The persistent concerns over whether AI infrastructure spending can generate adequate returns have triggered sustained selling across chip-related names.

United Microelectronics had previously accumulated a decline exceeding 18% over multiple consecutive trading days. After a brief rebound on July 21-22 driven by sector recovery, the stock resumed its downward trajectory, indicating that systematic selling pressure has not yet been effectively released. On the fundamental side, the company reported Q2 revenue growth of nearly 17% year-over-year, reaching a 15-quarter high, and its Singapore fab has achieved mass production of its first silicon photonics wafers. The next earnings report is scheduled for July 29.
