On July 17, ASE Technology fell 5.85% in pre-market trading, trading at $37.04/share, with turnover of $582,500.

The decline was driven by a broad semiconductor sector selloff combined with accelerated profit-taking following the stock's prior sharp rally. ASE Technology had previously surged over 10% in a single session after reporting June consolidated revenue of NT$65.78 billion, up 32.9% year-over-year, with its core ATM business jumping 41.8% year-over-year. The stock has since retreated over multiple consecutive sessions as short-term gains are unwound.

Within the Semiconductors sector, major peers declined broadly: Micron Technology down 4.53%, Advanced Micro Devices down 4.14%, Intel down 3.82%, Taiwan Semiconductor Manufacturing down 3.66%, and NVIDIA down 2.84%. The systemic sector pressure made it difficult for individual stocks to avoid the downdraft. The company's July 1 announcement of advanced packaging price hikes exceeding 20% provides medium-to-long-term fundamental support, but near-term technical selling pressure remains dominant.
