Shares of Amkor, Himax, and Entegris fell sharply in afternoon trading as investors took profits across the chip sector following a strong first-half rally and escalating Middle East tensions. The selloff was triggered by a more than 5% drop in SK Hynix shares in South Korea after a local brokerage lowered its second-quarter earnings forecast, projecting operating profit of 60.4 trillion won, roughly 8% below the 65 trillion won market consensus. The expected miss was attributed to the company's heavy reliance on long-term fixed-price contracts for its premium High Bandwidth Memory chips, which prevented it from benefiting from recent 30% to 50% price surges in the spot market. This revelation prompted a reassessment of the memory sector, accelerating profit-taking among investors already questioning the durability of AI capital spending. Amkor fell 6.9%, Himax dropped 7.3%, and Entegris declined 6.5%.
