Head and Shoulders Top
Well-DocumentedA three-peak reversal pattern that forms at the end of an uptrend, where a higher middle peak (the head) sits between two lower, roughly equal peaks (the shoulders), separated by a support line called the neckline.
Candlestick chart showing an uptrend rising into a left shoulder peak, pulling back, rising higher to form a head peak, pulling back to a similar level (forming a roughly flat neckline), rising again to a right shoulder peak lower than the head, then breaking down decisively through the neckline into a new downtrend.
Sample data — illustrative only, generated to demonstrate this pattern's shape. Not a real security.
Identification Criteria
- Forms only after a sustained, identifiable uptrend — without a prior advance, a similar shape is just noise.
- Left shoulder: price rallies to a peak, then pulls back on a wave of profit-taking.
- Head: price rallies again to a new high, clearly above the left shoulder, then pulls back to roughly the same level as the first pullback.
- Right shoulder: price rallies a third time but fails to reach the height of the head, then turns down again.
- A neckline connects the two pullback lows; it can be flat or gently sloped in either direction.
- Volume is often (not always) heaviest on the left shoulder and head, and lighter on the right shoulder — a classic waning-momentum signature.
Formation Logic
The pattern reflects a gradual exhaustion of buying pressure. Each rally attempt is met with selling, and the failure of the third rally (the right shoulder) to reach the head's high is the first visible sign that demand is losing to supply. The neckline represents the support level that buyers have defended twice already — a close below it removes that support.
Breakout / Confirmation Rule
The pattern is only considered complete when price closes decisively below the neckline, ideally accompanied by an increase in volume. A break on low volume, or a break that is not followed by a close beyond the neckline, is treated as unconfirmed and carries a materially higher risk of failing.
Measured-Move Price Target
A widely used, purely illustrative measured-move technique: measure the vertical distance from the head's peak to the neckline, then project that same distance downward from the point where price breaks the neckline. This is a heuristic for framing risk/reward, not a guaranteed outcome.
Common Pitfalls
- Mistaking a normal pullback within an uptrend for a right shoulder before the neckline actually breaks.
- Acting on a neckline touch rather than a confirmed close below it — many "breaks" are false and price returns above the neckline.
- Ignoring an upward-sloping neckline, which requires a lower breakout level than a flat one and changes the measured-move math slightly.
- Treating the pattern as valid without a clear prior uptrend to reverse.
