Inverse head and shoulders

An inverse head and shoulders pattern is a bullish reversal formation consisting of three distinct lows (troughs): a shoulder (lower left), a head (deeper center), and a shoulder (lower right), with two peaks between them forming an approximately flat neckline. The pattern reveals that a downtrend has exhausted—the middle trough (head) reaches a lower low than the prior trough, but the subsequent trough (right shoulder) is higher than the head, showing strengthening buying. When price breaks above the neckline, the reversal is confirmed. It is the bullish mirror of the head and shoulders and is similarly regarded as one of the more reliable reversal patterns.

How inverse head and shoulders forms

The pattern unfolds over weeks or months in a downtrend. The first trough (left shoulder) forms as sellers push price lower, then cover. Price rallies to a resistance level (the neckline). Sellers return, pushing price even lower—this is the head, the lowest point in the pattern. Buyers step in at this depth and price rallies back to approximately the same level as the previous high (the neckline).

Sellers make one more attempt to push price lower, creating the right shoulder. But this trough is shallower than the head, revealing weakening selling power. This is the crucial signal: the downtrend is fading. Buyers then push price above the neckline, completing the pattern and confirming the reversal.

The neckline

The neckline is the horizontal (or slightly sloped) line connecting the two highs between the three troughs. It acts as resistance. When price breaks decisively above the neckline, the pattern is complete, and a sustained uptrend often follows.

The neckline can be perfectly horizontal or sloping slightly upward or downward.

Volume and the pattern

Volume typically declines as the pattern develops—reflecting consolidation and buying indecision. On the final break above the neckline, volume often surges, confirming buyers are taking control.

The measuring objective

Once the pattern is confirmed (price closes above the neckline), traders calculate the expected upside target. The formula is: neckline level plus the depth of the head below the neckline. For example, if the head is at $80, the neckline at $95, then the measuring objective is $95 + $15 = $110.

Variations

Sloppy neckline: The two highs are not at exactly the same level; one shoulder is shallower than the other. The pattern is still valid but less clean.

Rounded head: The head is not a sharp trough but a rounded bottom. The pattern works, though it is less visually striking.

Multiple shoulders: Some patterns have four or more troughs, with the two center ones clearly deeper than the outer ones.

False breakouts

Price can briefly break above the neckline on low volume, then reverse back below it. High volume on the breakdown and a decisive close above the neckline increase the likelihood the reversal is genuine.

Trading inverse head and shoulders

Confirmation: Many traders wait for price to close clearly above the neckline before entering a long position.

Entry: Buy at the neckline break, or wait for a pullback to the neckline for confirmation.

Stop-loss: Place below the right shoulder’s low or below the head.

Profit target: Use the measuring objective; price often extends further.

Inverse H&S at the bottom of downtrends

An inverse head and shoulders at the bottom of a major downtrend (after weeks of declining) is more significant than one appearing after a brief, minor decline. The longer the prior downtrend, the more meaningful the pattern.

Comparison to bullish reversals

• Inverse head and shoulders: Three troughs; clear reversal; high reliability.
• Double-bottom: Two troughs; simpler; less reliable than inverse H&S.
• Morning star: Three candles; reversal; different timeframe.

Real-world example

A stock declines from $130 to $85 (left shoulder), rallies to $105 (first neckline high), declines to $75 (head), rallies to $103 (second neckline high), declines to $82 (right shoulder), then closes above $103 on high volume. The measuring objective is $103 + $28 = $131.

Academic perspective

Academic research on inverse head and shoulders finds mixed results, similar to the bearish version. Some studies suggest modest predictive power; others find no edge.
