Applied Materials, Lam Research, Marvell Technology, Micron, and Semtech Shares Skyrocket, What You Need To Know

• Beaten-down chip stocks rebounded after JPMorgan upgraded Intel and Treasury yields eased. • Rally follows a 4.5% Nasdaq drop driven by AI-spending durability doubts and widening credit spreads. • Lam Research up 49.6% YTD but still 36% below its 52-week high; gains may be tactical dip-buying. Semiconductor stocks rebounded after a rough prior week in which the Nasdaq fell 4.5% on doubts about AI infrastructure spending, following Anthropic's $16.8 billion Q3 revenue report and widening credit spreads among debt-funded compute providers. Sentiment improved after JPMorgan upgraded Intel to neutral and the 10-year Treasury yield pulled back, easing pressure on balance-sheet-sensitive chipmakers. Applied Materials, Lam Research, Marvell, Micron, and Semtech all gained 3-4.3% in the move. Lam Research, up 49.6% year to date but still 36% below its June 2026 high of $433.33, has seen 52 moves of more than 5% over the past year, suggesting the market views the news as meaningful but not business-changing. With major platform earnings due later in the week, the rally's durability hinges on whether software monetization can justify continued hardware capex growth.
