Lam Research Slides After 30% Nasdaq Rally Sparks AI Valuation Doubts
LRCX•Lam Research shares slid alongside semiconductor peers as investors question whether massive AI infrastructure spending justifies current valuations. Samsung’s robust quarterly earnings beat failed to offset broader sector pressure, with the Nasdaq up 30% since March raising profit-taking risks.
1. Semiconductor Stocks Under Pressure
Lam Research shares declined in line with a broader semiconductor sell-off as investors grow more selective about chipmakers tied to AI growth. A sector-wide pullback saw peers like KLA and Applied Materials also fall, reflecting concerns over near-term demand.
2. Valuation Concerns Around AI Infrastructure
Market sentiment has shifted from questioning AI demand to doubting whether anticipated infrastructure investments can support current multi-year highs in valuations. The Nasdaq’s 30% gain since March has amplified profit-taking risk if upcoming earnings miss lofty projections.
3. Samsung’s Earnings Beat Offers Limited Relief
Samsung Electronics reported a stronger-than-expected quarterly profit, but the surprise wasn’t enough to reverse the semiconductor downturn. Investors remain cautious that even leading players may struggle if capex on AI hardware slows.
