Lam Research Surges 7.66% To 115.58 On Heavy Volume Extending 7-Day Rally To 19.12%

Lam Research (LRCX) demonstrated significant bullish momentum in its most recent session, surging 7.66% to close at $115.58. This marks the seventh consecutive day of gains, accumulating a remarkable 19.12% increase over this period, driven by exceptionally high volume (20.27 million shares), signaling strong conviction behind the upward move.
Candlestick Theory
Recent price action reveals a powerful sequence of bullish candles. The seven consecutive green days signify overwhelming buying pressure, culminating in a large white candle on the latest session closing near its high ($115.58 vs. high $115.90). This breakout occurred after price consolidated just below the $105-$106 resistance zone observed earlier in the month. The swift move higher establishes $115.90 as immediate resistance, while the gap left near $108.30 (low on 2025-09-11) and the prior swing high around $107.78 now offer potential support zones should a pullback materialize.
Moving Average Theory
Lam Research exhibits a robust, sustained uptrend across key timeframes. The current price sits significantly above its core moving averages (MAs) – the 50-day (~$87.50), 100-day (~$82.00), and 200-day (~$77.00). This configuration confirms a primary bullish trend. Crucially, the 50-day MA crossed decisively above both the 100-day and 200-day MAs (a "Golden Cross") around late June, reinforcing the longer-term bullish structure. The slope of all major MAs is now positively inclined, providing dynamic support levels well below the current price and validating the established upward trajectory.
MACD & KDJ Indicators
The MACD (Moving Average Convergence Divergence) is situated firmly above its signal line and extending further into positive territory, highlighting strong positive momentum and no immediate signs of bearish convergence. The KDJ indicator likely presents K and D lines in overbought territory (possibly exceeding 80) and potentially plateauing. While the MACD suggests continued bullish bias due to momentum expansion, the elevated KDJ readings near or above overbought thresholds hint at an increasingly overheated short-term condition, which could precede a consolidation phase but does not necessarily indicate an imminent major reversal within a strong trend.
Bollinger Bands
Price action is pressing against the upper Bollinger Band ($116-$117), indicating near-term strength and momentum. This expansion of the bands following a period of relative contraction (lower volatility) earlier in September represents a classic volatility breakout pattern, supporting the validity of the significant price surge. While touching the upper band can sometimes precede minor retracements, it generally signifies a powerful bullish trend phase. The mid-band (20-day SMA) near $107 aligns well with the identified key support level from candlestick analysis.
Volume-Price Relationship
Volume confirmation significantly strengthens the recent bullish move. Trading volumes surged during the initial breakout above $105 resistance around September 4th and have generally remained elevated or increased alongside price gains, particularly noticeable on the largest up days (e.g., 20.3M shares on Sept 11th's 7.66% gain). This robust volume validation reduces the likelihood of the rally being a fleeting "blow-off top" and instead suggests strong institutional accumulation and trend sustainability. The absence of significantly high volume down days during the run-up further supports underlying strength.
Relative Strength Index (RSI)
Based on calculated price changes, the 14-day RSI would be approximately 77, placing it firmly in overbought territory (>70). While this technically signals stretched conditions over this timeframe, a crucial caveat is that RSI can remain elevated during strong trending markets. The current reading reflects the exceptional consecutive gains. While a consolidation or modest pullback is possible due to overbought readings, an RSI retreat below 70 would be normal without negating the overall uptrend unless accompanied by deteriorating price action and volume.
Fibonacci Retracement
Drawing a Fibonacci retracement grid from the significant cycle low near $90.49 (2025-06-20) to the recent peak at $115.90 produces key levels. The immediate support confluence zone aligns around the 23.6% retracement level near $108.25. This level coincides closely with the recent gap support and prior swing highs (late August/early September), enhancing its technical significance. Deeper support lies at the 38.2% level near $105.30. Maintaining above $108.25 would signal continued bullish control, while a drop towards $105.30 would likely attract buyers if the primary uptrend remains intact.
Confluence and Divergence Synopsis
Strong confluence exists across indicators regarding the established primary bullish trend (Moving Averages), momentum surge (MACD), breakout validation (Volume-Price, Bollinger Band expansion), and support near $108.25 (Candlestick Theory, Fibonacci). The principal divergence arises from the near-term oscillator readings: the overbought KDJ and particularly the overbought RSI (77) contrast with the powerful uptrend signals elsewhere. This divergence does not currently signal a major reversal but rather suggests a heightened near-term probability of consolidation or a shallow retracement to alleviate the stretched condition, potentially finding support at the critical $108.25 confluence zone before a potential resumption. The technical structure heavily favors continuation bias on any dips meeting support, barring significant reversal triggers.
