On September 14, Amkor Technology fell 5.28% in pre-market trading, trading at $48.88 per share, with turnover of approximately $291,700. The decline came as the company's massive capital expenditure plan and ongoing strategic uncertainty weighed on sentiment, compounded by broad weakness across the semiconductor equipment sector.

On the news front, Amkor Technology recently announced the launch of phase 2 construction at its advanced packaging and test campus in Arizona, raising the total planned investment to approximately $12 billion. The scale of the capital commitment has triggered market concerns over near-term earnings dilution. Additionally, the company has reportedly been exploring a partial stake sale of its China business, with the unit valued at an estimated $1 billion to $1.5 billion. The company has hired an adviser to gauge interest among potential buyers, including Asian investment firms and industry players. The strategic uncertainty surrounding the China divestiture continues to pressure market sentiment.

Within the Semiconductor Equipment sector, the overall sector posted broad declines. Among individual stocks, Lam Research fell 5.11%, Applied Materials fell 4.96%, ASML Holding fell 4.27%, KLA Corporation fell 5.00%, and Teradyne fell 5.19%.
