What the head and shoulders pattern is
The head and shoulders is a bearish reversal pattern made of three peaks. The first, the left shoulder, is followed by a higher peak, the head, and then a lower peak, the right shoulder, roughly level with the left. The line joining the two lows between the peaks is the neckline. A head and shoulders trade is planned around the neckline break, a stop-loss above the right shoulder and a measured downside target.
It tells a story of fading demand. Buyers push to a new high at the head, but the next rally, the right shoulder, fails well below it: a lower high after a long run of higher highs. If price then breaks the neckline, the uptrend is over, at least for now.
As a reversal pattern, it needs a clear rise before it. The shoulders need not be identical, and the neckline may slope a little. Volume is often lighter on the right shoulder than on the left.
How the head and shoulders is confirmed
Until the neckline breaks, the pattern is only a possibility; many stocks form a right shoulder and then go on to new highs. It is confirmed when price closes below the neckline.
Look for:
- a daily close below the neckline, not just an intraday dip;
- volume on the breakdown day above the recent average;
- a weak rally back to the neckline afterwards, which often stalls there because broken support tends to act as resistance.
Head and shoulders stop-loss and target
The pattern can be traded as a short: sell first, buy back lower. In Indian markets, shares can be shorted in the cash segment only within the day; holding a short overnight needs futures or options, which carry their own risks. Many swing traders use the pattern instead as a signal to exit a holding or to avoid buying.
For a short, the stop-loss goes above the entry. The usual place is just above the right shoulder: if price climbs back over it, the lower high is gone and the pattern has failed. A tighter stop just above the neckline is possible, but the retest rally often reaches it.
The target uses the measured move: take the height from the top of the head down to the neckline and project it downward from the breakdown point. A head ₹100 above the neckline gives a first target ₹100 below it. Because the right shoulder is lower than the head, the stop is usually nearer than the target, which gives a better reward-to-risk than a double top.
Sizing the head and shoulders trade
For a short, the risk per share is the stop minus the entry:
Shares = risk in ₹ ÷ (stop-loss − entry)
A separate example with round numbers: shoulders near ₹600, a head at ₹650 and a neckline at ₹550, so the pattern is ₹100 tall and the target is ₹450. You short at ₹545 after the breakdown and place the stop at ₹605, above the right shoulder. Your risk is ₹60 a share. If you are willing to risk ₹3,000, you can short ₹3,000 ÷ ₹60 = 50 shares. The target is ₹95 below your entry, so the reward is about 1.6 times the risk.
The Position Size Calculator does this for you and shows your risk per trade. Shorts can be hurt by an upward gap, so allow for slippage.
Common mistakes
- Acting on the right shoulder before the neckline breaks.
- Finding a head and shoulders in every three bumps on a chart, without a real rise before it.
- Shorting without a stop-loss, so the possible loss has no limit.
- Ignoring the broader market: the pattern fails more often when the whole market is rising.
- Covering a short in panic on the retest rally, then re-entering lower without a plan.
How often the head and shoulders fails
Often. The pattern is well known, but breakdowns below the neckline frequently reverse, and price can rally back above the right shoulder and the head. A sloping or messy neckline makes it harder still to say when the pattern is confirmed. Nobody can tell in advance which breakdowns will follow through, and the pattern guarantees nothing.
Its value is a clear point of failure. Size each trade so that the stop costs only a small, planned amount.
