On August 18, Amkor Technology fell 6.07% in regular trading, trading at $57.41 USD/share, with turnover of $18.86 million.

The decline came amid broad weakness across the semiconductor equipment sector, driven by surging U.S. Treasury yields pressuring growth stock valuations. The 30-year U.S. Treasury yield climbed to 5.29%, its highest level since 2007, triggering selling across technology names. Within the sector, Applied Materials fell 5.06%, Lam Research dropped 5.53%, ASML declined 3.75%, KLA Corporation lost 3.52%, and AXT Inc fell 5.58%.

Amkor Technology had previously risen on news of a potential stake sale of its China business, valued at an estimated $1 billion to $1.5 billion, and a $1.5 billion multi-year AI chip packaging partnership with Nvidia announced in late July. However, broader macro headwinds overshadowed these positive catalysts during the session.
