Semiconductor Momentum: LRCX's 44% Gain in 57 Days
Lam Research (LRCX) gained 44% in 57 days as semiconductor momentum accelerated. This trade combined RSI divergence, volume analysis, and sector rotation—here's the complete technical breakdown.
📊 The LRCX Trade
Entry (Dec 1, 2025)
Exit (Jan 27, 2026)
Technical Analysis: The 4 Indicators That Signaled the Move
1. RSI Divergence (Most Important)
The Relative Strength Index (RSI) showed bullish divergence in late November—price made lower lows while RSI made higher lows. This is one of the most reliable reversal signals.
RSI Timeline:
Why RSI Divergence Works:
When price makes new lows but RSI doesn't, it shows selling pressure is weakening. Smart money is accumulating while retail panics. This often precedes strong rallies. Win rate: 65-70%.
2. Volume Analysis
Volume confirmed the reversal. On Dec 1, LRCX had 35% above-average volume on the bounce—institutional buying.
Volume Pattern:
- • Decline (Nov 15-28): Below-average volume (weak selling)
- • Bounce (Dec 1): 35% above average (strong buying)
- • Rally (Dec-Jan): Consistent above-average volume
Volume Trading Rules:
Bullish: Price up + volume up = strong trend
Bearish: Price up + volume down = weak rally (avoid)
Key: Compare to 20-day average volume, not just previous day
3. Relative Strength vs SPY
LRCX was outperforming SPY by 2:1 ratio. When a stock shows relative strength during market weakness, it's a powerful signal.
Relative Strength Calculation:
How to Use Relative Strength:
RS > 1.5: Stock is a leader, prioritize it
RS 0.8-1.2: Moving with market, neutral
RS < 0.8: Lagging market, avoid
Best trades: RS > 2.0 in strong sectors
4. Sector Rotation Signal
Semiconductors were rotating into favor. When multiple stocks in a sector show similar patterns, it's sector momentum—not just individual stock strength.
Semiconductor Sector (Dec 2025):
Sector Rotation Strategy:
When 3+ stocks in a sector show similar technical setups (RSI divergence, volume, breakouts), it's sector rotation. Trade the strongest stock in the strongest sector. LRCX had the lowest RSI (most oversold) = best entry.

Educational Deep Dive: Understanding RSI
What is RSI?
The Relative Strength Index (RSI) measures momentum on a scale of 0-100. It compares the magnitude of recent gains to recent losses.
RSI Formula:
RSI Divergence: The Most Powerful Signal
Bullish Divergence (What LRCX Showed):
Price makes lower low, RSI makes higher low = Selling exhaustion, reversal coming
Bearish Divergence:
Price makes higher high, RSI makes lower high = Buying exhaustion, top forming
Pro Tip: RSI divergence works best when combined with volume confirmation. LRCX had both—that's why it gained 44%.
Key Takeaways for Your Trading
RSI Divergence is Gold
When you see bullish divergence + volume confirmation, take the trade. Win rate: 65-70%.
Volume Confirms Everything
Price moves without volume are fake. Always check if volume is 20%+ above average.
Trade Sector Leaders
When a sector rotates, trade the stock with the best technical setup (lowest RSI, highest volume).
Scale Out Profits
Take 50% at +15%, 25% at +30%, trail 25% with MA. This locks in gains while catching extended moves.
