Lam Research is trading 8.73% lower at $5.12 on October 15, 2026, amid a broad semiconductor selloff following hotter-than-expected U.S. inflation. - No company-specific catalyst surfaced; pressure also reflects renewed interest-rate concerns, doubts about the sustainability of AI infrastructure spending, and intensifying Chinese chip competition. - The shares have reportedly declined more than 10% over the previous six sessions. Quarterly results are scheduled for October 21, but available reporting does not identify them as the cause of this move.
