On June 2, UMC fell 3.28% in pre-market trading, trading at $22.16/share, with trading volume of $378,100.
The decline was primarily driven by valuation concerns following a sharp run-up. UMC's trailing twelve-month P/E ratio has been pushed to 36.7x, far exceeding its five-year median of 11.8x, creating significant reversion pressure. The broader semiconductor sector also weighed on sentiment, with Micron Technology down 0.6%, Intel down 1.71%, and AMD down 1.1%.
Despite strong fundamental catalysts — including Q1 net profit surging 108% YoY to NT$16.17 billion, gross margin expanding to 29.2%, capacity utilization recovering to 79%, and management confirming selective price hikes of approximately 10% for the second half — market focus has shifted to the elevated valuation risk accumulated during the stock's rapid appreciation in recent sessions. UMC had risen over 10% in pre-market trading on May 26-27 alone, amplifying the current pullback dynamics.
