On August 18, Amkor Technology fell 5.06% in pre-market trading, trading at $58.2/share, with turnover of $495,700. The decline comes after the stock gained approximately 4.57% in the previous session, largely giving back those gains amid broad semiconductor equipment sector pressure.

The Semiconductor Equipment sector where Amkor Technology belongs saw widespread selling in pre-market trading. Among individual stocks, Applied Materials fell 4.19%, Lam Research fell 4.12%, KLA Corporation fell 3.62%, ASML Holding fell 3.54%, and AXT Inc fell 7.39%. The sector-wide pullback follows a strong prior session where multiple semiconductor equipment names had posted gains exceeding 5%, suggesting profit-taking across the group.

Amkor Technology previously rallied on reports that the company is exploring a potential stake sale of its China business at an estimated valuation of $1 billion to $1.5 billion, as well as its multi-year $1.5 billion AI chip packaging partnership with Nvidia announced in late July. The current pre-market weakness appears driven primarily by sector-level selling pressure rather than company-specific developments.
