Applied Materials is trading at $395.78, down 3.22%, after hours on October 21, 2026, amid a likely Lam Research read-through; no verified company-specific announcement explains the decline.
- Lam Research beat quarterly estimates and issued broadly in-line guidance, but its shares fell about 6% after hours.
- SOXX was up 2.61%, so broad semiconductor strength does not explain the drop.
- Egerton’s disclosed sale is prior context, not a clear new catalyst.
