Why Is ASE Technology Holding (ASX) Stock Price Down 6.64% Today, July 24? Chip Risk Reset

ASE Technology Holding fell 6.64% as semiconductor risk appetite weakened and profit-taking accelerated after the stock broke a key near-term support zone, despite no same-session negative operating update. The move reads as sector-driven de-risking tied to valuation and AI capex durability concerns, with a secondary overhang from disclosed executive selling. Near-term trading conditions look fragile until chip-sector breadth stabilizes.
