Head and Shoulders: The Most Reliable Reversal Pattern
The head and shoulders is a classic chart pattern that signals a trend reversal from bullish to bearish.
What Is the Head and Shoulders Pattern?
The head and shoulders is one of the most recognized and reliable chart patterns in technical analysis. It's a bearish reversal formation that appears after an uptrend and signals that buyers are losing control. The pattern resembles a head with two shoulders on either side, making it easy to identify on a chart.
What the Pattern Looks Like
The head and shoulders consists of four components:
- Left shoulder: A peak formed during the uptrend
- Head: A higher peak that forms the top of the pattern
- Right shoulder: A lower peak that fails to reach the head's height
- Neckline: A support line connecting the lows between the shoulders and head
The neckline can be horizontal or sloped (up or down). A downward-sloping neckline is considered more bearish because it shows buyers accepting lower support levels.
What It Signals
The head and shoulders signals that each successive rally is weaker than the last. The lower right shoulder shows buyers can no longer push price to new highs, indicating exhaustion of the uptrend. Once the neckline breaks, the pattern is confirmed.
The pattern is only complete when price closes below the neckline. Before that, it's only a setup.
How to Trade It
- Identify all four components — left shoulder, head, right shoulder, neckline.
- Enter on the neckline break. Short when price closes below the neckline.
- Place your stop-loss above the right shoulder.
- Measure the target. The expected move equals the distance from the head's peak down to the neckline, projected downward from the breakout point.
Trading Example
A stock rises from $40 to $60, forms a left shoulder at $58, a head at $62, and a right shoulder at $57. The neckline sits at $52. When price breaks below $52, traders enter short with a stop above $57. The target is $62 - $52 = $10, projected down from $52 to give a target of $42.
Common Mistakes
- Entering before the neckline breaks
- Drawing the neckline incorrectly (it must connect the lows between shoulders)
- Ignoring volume — the right shoulder should ideally form on lower volume
Inverse Head and Shoulders
The bullish counterpart — the inverse head and shoulders — forms after a downtrend and signals a reversal upward. The mechanics are identical but inverted.
The head and shoulders pattern is favored by swing traders and position traders because it provides clear entry, stop-loss, and profit target levels based on measurable pattern geometry.
