On September 11, ASE Technology declined 3.04% overnight, trading at $38.65 per share, with turnover of $694,500. The stock had already fallen 3.28% in the prior session, extending a pullback from recent highs.

The decline was driven by continued weakness across the semiconductor sector. Intel fell 0.56%, Broadcom dropped 0.16%, and Micron Technology edged down 0.06%, reflecting broad-based softness in chip stocks. ASE Technology had rallied nearly 10% from $37.51 on September 4 to $41.20 on September 9, fueled by Google TPU advanced packaging order expansions, Intel accelerating its EMIB outsourcing to ASE, and a strong August revenue report showing 45.7% year-over-year growth to NT$82.25 billion. Assembly, testing, and material revenue surged 53% to NT$51.29 billion. With no material change to the company's fundamentals, the current retreat appears largely driven by sector-wide sentiment and short-term profit-taking pressure following the sharp run-up.
