Lam Research Corporation closed at $307.16 on September 25, 2026, a decline of 0.09% from the prior session. The modest pullback followed a sharp weekly advance that left the semiconductor equipment maker up 14.04% over the past seven days.
Despite the near-term strength, LRCX remained down 2.39% on a 30-day basis, reflecting some choppiness in the broader trading environment over the past month. The stock's market capitalization stood at $384.51 billion as of the close.
The contrast between the 30-day decline and the seven-day gain suggests the recent week's move recaptured a significant portion of earlier losses. Thursday's flat finish indicated traders largely held their positions rather than extending or trimming exposure after the outsized run.
Lam Research is a major supplier of wafer fabrication equipment to the global semiconductor industry, making its share price closely watched as a gauge of capital spending trends among chipmakers.
