What is a VCP?

The Volatility Contraction Pattern (VCP) is Mark Minervini’s signature chart pattern. It occurs when a stock’s price swings contract over time — each successive pullback is shallower than the last, forming a series of tightening “contractions.”

This pattern signals that selling pressure is drying up and institutional buyers are absorbing available shares. When the pattern resolves, the stock often breaks out sharply on increased volume.

Anatomy of a VCP

A classic VCP has flat highs (the pivot resistance) and higher lows (each pullback bottoms higher than the last). Two valid variants:

Chart 1 — Clean VCP (no shakeout)

Price                                                   ___ Breakout!

  |           L1

• Highs are FLAT, not ascending — they form the pivot (resistance) line. P1 ≈ P2 ≈ P3.
• Lows rise: L1 (-30%) < L2 (-15%) < L3 (-5%). Each pullback bottoms higher than the last as supply gets absorbed.
• Each contraction is shallower than the previous (volatility drying up).
• Chart 2 (Undercut & Rally) is a special case: the last pullback briefly violates the prior low (L1). It looks like a breakdown, stops out weak longs, triggers shorts — then the stock rallies sharply back above the pivot. This shakeout flushes remaining supply and is often the best VCP setup.
• Pivot point: the resistance line connecting the highs. Breaking above it with rising volume is the entry signal.

Contraction terminology

• C1 (First contraction): The largest pullback, typically 20-35% from the high — peak P1 down to low L1.
• C2 (Second contraction): A shallower pullback, roughly half of C1 — peak P2 down to low L2 (higher than L1).
• C3 (Third contraction): Very tight, often 5-10% — this is the “sweet spot”. In Chart 1, L3 is the highest low; in Chart 2, L3 briefly undercuts L1 (Undercut & Rally).
• Pivot point: The right edge of the final contraction — the breakout entry.

Key measurements

How AlpharvestPro Detects VCPs

Our v3 VCP detection engine analyzes every stock in our coverage daily:

Detection Algorithm:

1. Identify the base: Find the recent swing high and the series of pullbacks that follow
2. Count contractions: Detect successive lower-high, higher-low formations
3. Measure tightness: Evaluate the narrowing of the most recent contraction
4. Check volume: Verify that volume is declining through the pattern (supply drying up)
5. Near-breakout flag: Mark stocks where the price is approaching the pivot point

How to Trade VCPs

Entry Rules:

1. Wait for the breakout: Buy when price moves above the pivot point on volume 50%+ above average
2. Don’t anticipate: Buying before the breakout means buying a stock that might not break out
3. Set a stop-loss: Place your stop just below the low of the final contraction (3-8% risk)

Quality Conditions:

• Minervini score 8+: Confirms an established uptrend
• RS Rating 80+: Outperforming the broader market
• Multiple contractions: More contractions = better supply absorption
• Tight final contraction: Narrow range = remaining sellers exhausted
• Volume dry-up near 1.0: Volume meaningfully below average

Common Mistakes:

1. Buying loose patterns: A 15-20% final contraction means the base isn’t done yet
2. Ignoring the market environment: Even a perfect VCP fails in a bear market — check market breadth first
3. Chasing after the breakout: If you miss the breakout day, don’t buy 5-10% above the pivot

VCPs Across 4 Markets

AlpharvestPro detects VCPs in all 4 markets with the same algorithm:

The number of VCPs varies with market conditions. In strong uptrends, you’ll see more patterns forming; in corrections, fewer stocks build proper bases.

FAQ

How many contractions does a VCP need?

Multiple contractions are required. A single pullback is just a correction, not a VCP — the pattern needs successive tightening pullbacks to demonstrate genuine supply absorption.

What timeframe works best for VCP detection?

Daily charts. Weekly charts can confirm the big picture, but the daily chart shows the contraction detail needed for precise entries.

Can a VCP fail after breaking out?

Yes. About 30-40% of VCP breakouts fail. That’s why stop-losses are essential — risk management matters more than pattern recognition.
