What you will learn
- Describe the structure of a head and shoulders top and its neckline
- Explain why the pattern suggests a reversal
- Recognize the inverse pattern at the bottom of a downtrend
- Estimate a measured-move price target after a neckline break
Where the previous lesson covered continuation patterns, this one covers the most famous reversal pattern in all of technical analysis: head and shoulders. A reversal pattern suggests that an existing trend is not merely pausing but actually ending and turning the other way. Whether or not you ever trade it, you will hear it referenced often, so understanding its structure is part of basic chart literacy.
Head and shoulders pattern (Rayner Teo)
A reputable walkthrough of the pattern and the neckline break. Watch how the right shoulder failing to make a new high signals weakening buyers.
The structure of the top
A head and shoulders top forms at the end of an uptrend and is built from three peaks. The first peak, the left shoulder, rises and then pulls back. The second peak, the head, rises higher than the first before pulling back again. The third peak, the right shoulder, rises but falls short of the head, roughly matching the height of the left shoulder. A line connecting the lows between these peaks is called the neckline. The shape resembles a head flanked by two shoulders, hence the name.
Key terms
- Head and shoulders top
- A reversal pattern of three peaks, a higher middle head between two lower shoulders, at the end of an uptrend.
- Neckline
- The line connecting the lows between the peaks. A break below it confirms the pattern.
- Inverse head and shoulders
- The upside-down version at the end of a downtrend, signaling a possible upward reversal.
- Measured move
- A target: the head-to-neckline distance projected from the neckline break.
Why it suggests a reversal
The pattern tells a story about a weakening uptrend. The lower right shoulder shows that buyers could no longer push price to a new high, a failure of the higher-highs pattern that defines an uptrend. The structure captures the moment when control is shifting from buyers to sellers. The pattern is confirmed only when price breaks decisively below the neckline, which is taken as the signal that the reversal is underway. Until that break, the pattern is merely potential.
The inverse pattern
The mirror image, called an inverse head and shoulders or a head and shoulders bottom, forms at the end of a downtrend and signals a potential reversal upward. It consists of three troughs, with the middle trough, the head, lower than the two surrounding troughs, the shoulders, and it is confirmed when price breaks above its neckline. Everything about it is the upside-down version of the top.
A reversal pattern is the market changing direction. Head and shoulders captures the moment buyers run out of strength and sellers take over.
Measured move and volume
Traders often estimate a price target for the move after a confirmed break using the measured move: the vertical distance from the head to the neckline, projected from the point where price breaks the neckline. Volume frequently adds confirmation, often declining as the pattern develops and then expanding on the neckline break, which suggests genuine conviction behind the reversal.
Estimating the measured-move target
A head and shoulders top has its head at 120 and its neckline at 100. Price breaks below the neckline at 100. What is the measured-move target?
- Measure the pattern height. From the head at 120 down to the neckline at 100 is 20.
- Project it down from the break. Subtract that 20 from the neckline break at 100.
- Read the target. 100 minus 20 is 80.
Why it matters: The projected move equals the height of the pattern. It is an estimate, not a promise, and should be paired with risk management.
Calculate the measured move
A head and shoulders top has its head at 60 and its neckline at 50. Price breaks below the neckline at 50. What is the measured-move target?

The familiar caution
All the skepticism from the chart-patterns lesson applies here too. Identifying a head and shoulders is subjective, and the pattern fails often enough that a neckline break is no guarantee of a reversal. Hindsight bias makes these formations look cleaner and more reliable in retrospect than they are in the moment. A head and shoulders is a probabilistic hint that the balance of power may be shifting, useful as one input, dangerous as a standalone prediction, and only as good as the risk management behind any trade based on it.
Is the pattern confirmed?
A stock has formed what looks like a head and shoulders top, with a clear head and two shoulders. Price is now sitting just above the neckline but has not broken it. A trader shorts immediately, calling the reversal. What is the flaw?
The pattern is only potential until price breaks decisively below the neckline. Shorting before that confirmation risks the pattern failing, so waiting for the break, ideally on rising volume, is the disciplined move.Name the parts
