Lam Research Plunges 3.86% Intraday, Is This a Technical Breakdown or Sector Reversal?

Summary
• Lam Research (LRCX) trades at $97.81, down 3.86% from its 2025-07-22 open of $101.0
• Intraday range spans $97.055 to $101.123 as sector leader AMAT declines 2.91%
• 52-week high of $102.59 now 5.4% above current price

Lam Research’s intraday plunge has ignited urgent scrutiny in a semiconductor sector otherwise buoyed by AI-driven demand. The stock’s sharp decline has breached critical support levels, with options volatility surging as traders debate whether this is a technical selloff or a sign of deeper sector challenges. With the stock now trading below its 30-day moving average and key Bollinger Band support, the question looms: is this a fleeting correction or a turning point?

Technical Breakdown Amid Sector Optimism
Lam Research’s 3.86% intraday decline reflects a technical breakdown rather than fundamental deterioration. The stock has pierced its 30-day moving average ($96.02) and now trades below key Bollinger Band support at $93.62. This follows a short-term bullish trend reversal flagged by the MACD histogram (-0.35) and RSI (67.24) hovering near overbought territory. While SEMI’s forecast of $125.5B 2025 equipment sales suggests sector strength, LRCX’s underperformance contrasts with ASML’s recent $2T valuation milestone and Tokyo Electron’s market cap surge past Sony. The selloff appears to be a reaction to overbought conditions and profit-taking, rather than a fundamental shift in semiconductor equipment dynamics.

Semiconductor Equipment Sector Mixed as AMAT Leads Decline
The Semiconductor Equipment & Materials sector shows divergent momentum. While SEMI’s mid-year forecast projects 7.4% equipment sales growth through 2026, sector leader Applied Materials (AMAT) trades down -2.96% alongside LRCX. This suggests broader technical pressures rather than sector-specific concerns. Notably, Tokyo Electron’s market cap surpassing Sony on NVIDIA-driven demand highlights divergent performance within the sector, with LRCX’s 3.6% drop diverging from ASML’s recent rally. The sector’s mixed performance underscores the importance of monitoring AMAT’s trajectory as a barometer for sector health.

Backtest Lam Research Stock Performance
The backtest of LRCX's performance after an intraday plunge of -4% shows favorable short-to-medium-term gains. The 3-Day win rate is 54.35%, the 10-Day win rate is 56.98%, and the 30-Day win rate is 61.25%. Although the maximum return during the backtest period is 7.96%, it suggests that LRCX tends to recover moderately well from such significant dips, with the maximum return occurring on day 59 after the event.

Critical Levels and Sector Leadership to Watch
The $93.62 Bollinger Band support and $97.16 intraday low will determine whether this is a technical correction or a trend reversal. With sector leader AMAT down -2.96%, investors should monitor ASML’s $2T valuation momentum for cross-sector cues. Short-term traders may find value in LRCX20250801P96 for volatility plays, while longer-term investors should watch the 52-week high retest at $102.59. If the $93.62 level holds, a mean reversion setup could emerge by mid-August expiry. Watch AMAT’s trajectory and LRCX’s support/resistance levels to gauge sector sentiment and position accordingly.
