$221.43−9.29 (−4.0%)
Gekko Brief
AI summaryNov 4 closeLam Research's shares moved this week on a mix of record financial results and emerging operational concerns. The company reported record fiscal first-quarter revenue and adjusted EPS, with operating margin exceeding 40% for the first time, driven by AI-fueled semiconductor demand, and calendar 2026 systems revenue is expected to grow over 40% year-on-year. Shares fell 4.14% on 2 November amid supply constraints, moderating sales guidance from China, executive stock sales, and institutional profit-taking, even as shareholders backed the board and pay plan at the annual meeting. The stock also saw continued insider share sales via Form 4 filings during the period.
LRCX closed at $221.43, down 4% from the prior close, with the price sitting below both its 50-day average of $289.28 and 200-day average of $284.33. Over the past month the stock has declined 33.7%, extending a three-month drop of 27.6%, though it remains up 37.3% over the past year. The GekkoIndex reads 69.8, placing the stock in the Accumulation zone. The price sits 18.2% below Gekko Fair Value of $270.81.
The next earnings report is scheduled for 27 January 2027, after close, placing it outside the typical 20-trading-day window.

Last earnings call, Oct 21, 2026 AI summary
- What they said
- Lam Research delivered record revenue, gross margin, operating margin, and EPS in the September 2026 quarter, with operating margin exceeding 40% for the first time. Calendar year 2026 systems revenue is expected to grow over 40% year-on-year, driven by AI-fueled semiconductor demand. DRAM and foundry logic accounted for ~80% of systems revenue growth YTD. WFE for 2026 is expected in the mid-$150 billion range.
- Guidance
- 2027 WFE outlook exceeds $200 billion, led by DRAM, then foundry logic and NAND. Supply chain constraints and cleanroom availability may limit near-term fulfillment. Lam expects its third consecutive year of WFE outperformance in 2026.
