On July 17, United Microelectronics fell 7.22% in regular trading, trading at $20.53/share, with turnover of $94.85 million. The stock extended its multi-day slide after already plunging over 7% in the prior session.

On the news front, the semiconductor sector continues to face broad-based selling pressure, with industry peers Advanced Micro Devices down 6.24%, Intel down 6.08%, Micron Technology down 4.31%, NVIDIA down 3.52%, and Broadcom down 3.37%, reflecting persistent systematic risk-off sentiment across the chip space.

On the fundamental side, United Microelectronics reported Q2 revenue growth of nearly 17% year-over-year, marking a 15-quarter high, and its Singapore 12-inch wafer fab successfully delivered its first batch of mass-produced silicon photonics wafers supporting 1.6Tbps high-bandwidth interconnect solutions. However, sustained sector-wide bearish sentiment has overwhelmed company-specific positives. The next earnings report is scheduled for July 29.
