Head and Shoulders Pattern

The Head and Shoulders pattern is a financial market analysis chart pattern that predicts a bullish-to-bearish trend reversal. It is one of the most reliable and frequently encountered trading patterns and is used by traders across a variety of asset classes, including equities, commodities, and forex.

Components of the Head and Shoulders Pattern

The Head and Shoulders pattern is composed of four main parts:

1. Left Shoulder: This is characterized by a price increase followed by a peak and then a decline.
2. Head: This forms when the price rises again, creating a higher peak than the left shoulder before it declines again.
3. Right Shoulder: The price rises again but does not reach the high of the head before declining.
4. Neckline: This is a support line drawn through the lows of the left shoulder, head, and right shoulder. The neckline can be upward sloping, downward sloping, or horizontal.

Types of Head and Shoulders Patterns

1. Standard (Top) Head and Shoulders Pattern: This indicates a reversal from a bullish trend to a bearish trend. It is formed after an uptrend and signals that the asset’s price is likely to move lower.
2. Inverse (Bottom) Head and Shoulders Pattern: This indicates a reversal from a bearish trend to a bullish trend. It is formed after a downtrend and signals that the asset’s price is likely to move higher.

Psychological Background

The formation of the Head and Shoulders pattern is driven by underlying market psychology:

• Left Shoulder: This reflects an initial attempt to continue an uptrend or downtrend.
• Head: Reflects a stronger attempt to push the trend further, reaching lower lows or higher highs.
• Right Shoulder: Reflects a weaker attempt which fails to surpass the trend established by the head, indicating a potential exhaustion in the trend.
• Neckline Break: A decisive break of the neckline confirms the pattern, reflecting a shift in market sentiment.

How to Trade Head and Shoulders Pattern

1. Identify the Pattern: Spot the Left Shoulder, Head, Right Shoulder, and the Neckline.
2. Wait for the Breakout: Do not trade until the price breaks the neckline.
3. Trade Entry: Once the neckline is broken, enter a trade in the direction of the breakout.
4. Stop Loss: Position your stop loss above the right shoulder (for Standard pattern) or below the right shoulder (for Inverse pattern).
5. Profit Target: Measure the distance from the top of the head to the neckline. Project this distance from the breakout point to estimate the profit target.

Example of Head and Shoulders Pattern

Consider the stock price of Company XYZ:

• Left Shoulder formed at $50 with a decline to $40.
• Head formed as the price rose to $60 and fell back to $40.
• Right Shoulder formed at $45 with a subsequent decline.
• Neckline is drawn at $40.
• Upon breaking the neckline at $40, the price fell to $25, confirming the pattern.

Related Concepts

• Volume Confirmation: Traders often look for volume confirmation, where volume should ideally decrease on the formation of the head and rise during the breakout.
• Trend Analysis: The Head and Shoulders is a reversal pattern, thus it is crucial to identify existing trends.
• Support and Resistance: The neckline acts as a support (for Standard pattern) or resistance (for Inverse pattern).
