On August 24, Amkor Technology fell 5.01% in regular trading, trading at $47.38/share, with turnover of approximately $41.16 million.

The decline came amid a sector-wide selloff in semiconductor equipment stocks. Rising U.S. long-term Treasury yields — with the 30-year yield approaching 5.3% — have pressured growth and high-valuation technology sectors, triggering risk-off sentiment across the semiconductor industry. The Philadelphia Semiconductor Index recently posted a 5% decline, and the broader tech sector experienced significant rotation as investors repriced duration-sensitive assets.

Within the Semiconductor Equipment sector, the overall industry showed uniform weakness. Among individual stocks, Applied Materials fell 2.94%, ASML Holding fell 1.62%, Lam Research fell 4.05%, KLA Corporation fell 2.93%, and AXT Inc fell 10.45%. Options market activity in sector names has also reflected elevated bearish positioning, with large directional put spreads reported in recent sessions.
