On August 3, Lam Research fell 4.82% in regular trading, trading at 280.2 USD/share, with turnover of $312 million.

The decline was driven by multiple converging factors. Japan's third round of semiconductor export controls on China officially took effect on August 1, covering 20 categories of advanced packaging equipment including HBM-compatible die bonders and TSV equipment, with near-80% rejection rates on AI chip-related export applications. This triggered a broad selloff across global semiconductor stocks, with Samsung Electronics and SK Hynix plunging approximately 7-8%, and Korea's KOSPI index briefly triggering a circuit breaker.

Simultaneously, Lam Research faced profit-taking pressure following its 23%+ single-day surge on July 30 after reporting record quarterly results. Several investment banks lowered price targets — Deutsche Bank cut to $320 from $385 and B. Riley to $350 from $385 — though both maintained Buy ratings. Within the semiconductor equipment sector, peers also declined: KLA Corporation down 4.24%, AXT Inc down 3.92%, Teradyne down 3.04%, Applied Materials down 2.87%, and ASML down 1.37%.
