On July 1, United Microelectronics Corporation (UMC) fell 3.14% in regular trading, trading at $26.05/share, with turnover of $38.616 million. The decline came as the broader semiconductor sector experienced significant selling pressure, reversing gains from the previous session.

On the news front, Morgan Stanley strategist Mike Wilson warned that the semiconductor sector may be approaching a cyclical peak, citing extreme short-term volatility in the Philadelphia Semiconductor Index and concerns that earnings revision breadth has reached historical extremes. Wilson noted that capital outflows from cloud service providers — key semiconductor capex customers — could signal an impending period of underperformance for the sector.

UMC had risen approximately 3-5% on June 30 on expectations that a global semiconductor price hike wave starting July 1 would benefit wafer foundry utilization rates and pricing. However, profit-taking and broader sector weakness erased those gains. Within the Semiconductors sector, Micron Technology fell 6.84%, AMD fell 5.01%, Intel fell 4.57%, TSMC fell 3.98%, and NVIDIA fell 2.93%.
