Head and shoulders pattern


Family VI · Charts & indicators

Not to be confused with support and resistance, candlestick pattern, chart pattern.

Head and shoulders pattern is a reversal chart pattern that appears after an uptrend and consists of three peaks: a left shoulder, a higher head, and a right shoulder of similar height to the left. A neckline is drawn through the lows between the peaks, and a decisive close below it is taken as confirmation of a trend change. The pattern is widely watched but not infallible; false breaks occur.

Structure and confirmation

The pattern requires an existing uptrend, three distinct peaks, and a neckline connecting the two intervening troughs. Volume often diminishes on the right shoulder and expands on the breakdown. Confirmation is a close below the neckline, though some traders wait for a retest. The measured move target is the distance from the head to the neckline, projected downward from the breakdown point.

Neckline (support)100
Head-to-neckline distance120 - 10020
Measured move target100 - 2080

Limitations

Patterns are subjective; different analysts may draw the neckline differently. False breakdowns are common, especially in low-volume markets. The pattern works best when combined with other evidence such as volume, momentum divergence, or a retest of the neckline. No pattern guarantees a reversal.
