Head and Shoulders Pattern: Rules, Target and Stop

Everybody recognises this one. That’s part of the trouble, because three bumps on a chart get called a head and shoulders routinely and most of the time they are simply three bumps. What gives the pattern meaning is the order flow underneath it.

What the pattern describes

Three attempts by buyers, each weaker than the one before it.

1. Left shoulder. A new high arrives on strong volume, and nothing about it looks wrong.
2. First trough. Price pulls back the way it always does, and buyers step in again.
3. Head. Price makes a higher high, often on lower volume than the left shoulder, and this is the first warning worth noticing: reaching that high took less buying than the previous one did, so fewer participants were willing to chase it higher.
4. Second trough. Price falls back to roughly the level of the first trough, and those two troughs define the neckline.
5. Right shoulder. Here’s the tell, because buyers try once more and cannot reach the head, and demand has stopped producing higher highs.
6. Neckline break. Buyers are demonstrably spent by now, so the floor gives way.

Identification rules

Six conditions, and the pattern wants all of them:

• A clear preceding uptrend, because without one there’s nothing to reverse
• Three peaks, the middle one clearly the highest
• Roughly comparable shoulders, each with real height above the neckline, allowing for a little difference between them
• A neckline drawn through the two troughs, sloping if that’s how the troughs sit
• Declining volume across the three peaks, ideally
• A close below the neckline, because an intraday poke doesn’t count

The inverse version is the exact mirror at a bottom: three troughs, the middle one lowest, breaking upward through the neckline. Flip the signs and everything here still applies.

Measuring the target

Target = Neckline − (Head − Neckline)

On the chart above the head peaks near $76, and the neckline sits around $55. Height is $21, so a break at $55 projects to roughly $34.

Two qualifications matter more than the formula does.

Look at what sits in the way. If real support is parked at $48, that’s the realistic first target whatever the arithmetic projects, because a measured move is a piece of geometry with no knowledge of the buyers waiting a few points above it, and structure wins that argument more often than the formula does.

Treat the projection as an expectation. A meaningful share of patterns fall short, so take partial profit as price travels toward it.

The trade

Enter on the close below the neckline, or wait for the retest. Broken necklines get probed from beneath often enough to make the wait worthwhile, support turns into resistance on the way past, and that second entry usually offers better reward-to-risk than the break itself because the stop can sit so much closer to the level.

Stops go above the right shoulder. That high was the last genuine attempt buyers made, so price back above it means the pattern has failed. The neckline itself is the tighter alternative.

Size from the stop distance. A head and shoulders on a $70 stock can carry an $8 stop, and the position size calculator turns that into a share count.

Why it fails

No preceding trend. Three bumps inside a range are three bumps.

Volume rising into the right shoulder contradicts the whole premise, since the pattern is a description of exhaustion and a third attempt that draws more participation than the first two is describing something else entirely.

Identified after the fact. Spotting it once the neckline has already broken means you are describing history, so mark the neckline while the right shoulder is still forming.

Sometimes the neckline just holds. Textbook formations fail regularly. That’s what the stop is for.

Next, compare this against double tops and bottoms, which describe similar exhaustion with a simpler structure, and read support and resistance. The neckline is a level, and everything that governs levels governs it.
