Lam Research Stock Jumps 7% as Chip Equipment Names Lead Semiconductor Sector Rally

Lam Research shares climbed as much as 7% on Friday, September 18, reversing a portion of recent losses and outpacing the broader semiconductor sector. Applied Materials rose 4% and KLA Corp. gained 3% on the same session, with buying concentrated in chip equipment and tools stocks rather than chip designers and foundries. Analysts attributed the move to expectations of future capital spending on semiconductor infrastructure rather than immediate demand, with the group seen as a direct beneficiary of sustained AI-driven capital expenditure by chipmakers and data center operators.

The rally unfolded even as a wider technology sell-off was triggered by Anthropic CEO Dario Amodei's public call for an AI slowdown, suggesting investors are treating chip equipment makers as resilient to near-term AI sentiment swings. Lam Research ended the session up roughly 7%, according to Seeking Alpha. The company had previously raised its quarterly dividend 27% to $0.33 per share, with an ex-dividend date set for September 23, 2026, adding an income angle to the stock's appeal. Analysts are projecting approximately 70.6% year-over-year EPS growth for the company, which has drawn fresh buy recommendations heading into the move.
