Why Lam Research (LRCX) fell 4.21%
Lam Research (LRCX) fell 4.21% on November 13, 2026 — Chip supply-chain selloff drags equipment names.
What happened
Lam Research fell 4.2% with the Chip Supply Chain selloff, as Nvidia's slide led chipmaker weakness across the S&P 500 and Nasdaq. The move was shared across the group.
Why it moved
Lam sells wafer-etch and deposition tools, so its stock tracks semiconductor capex sentiment. When the complex de-rates together, equipment names fall in lockstep even without company news.
Why it matters
Lam is one of the equipment leaders in the Chip Supply Chain theme, and its AI-capex thesis is being tested by the broader chip pullback.
What would break the thesis
A reversal in the chip leaders, or evidence that wafer-fab spending is holding up, would bring equipment names back. Persistent sector weakness would signal the capex narrative is cooling.
