On the technical analysis chart, the head and shoulders formation occurs when a market trend is in the process of reversal either from a bullish or bearish trend; a characteristic pattern takes shape and is recognized as reversal formation.[1]
Head and shoulders top edit
Head and shoulders formations consist of a left shoulder, a head, and a right shoulder and a line drawn as the neckline.
The left shoulder is formed at the end of an extensive move during which volume is noticeably high.
After the peak of the left shoulder is formed, there is a subsequent reaction and prices slide down somewhat, generally occurring on low volume.
The prices rally up to form the head with normal or heavy volume and subsequent reaction downward is accompanied with lesser volume.
The right shoulder is formed when prices move up again but remain below the central peak called the head and fall down nearly equal to the first valley between the left shoulder and the head or at least below the peak of the left shoulder. Volume is lesser in the right shoulder formation compared to the left shoulder and the head formation.
A neckline can be drawn across the bottoms of the left shoulder, the head and the right shoulder.
When prices break through this neckline and keep on falling after forming the right shoulder, it is the ultimate confirmation of the completion of the head and shoulders top formation.
It is quite possible that prices pull back to touch the neckline before continuing their declining trend.[2]
Head and shoulders bottom edit
This formation is simply the inverse of a head and shoulders top and often indicates a change in the trend and market sentiment.[3]
The formation is upside down and the volume pattern is different from a head and shoulder top.
Prices move up from first low with increase volume up to a level to complete the left shoulder formation and then fall down to a new low.
A recovery move follows that is marked by somewhat more volume than seen before to complete the head formation.
A corrective reaction on low volume occurs to start formation of the right shoulder and then a sharp move up due to heavier volume again breaks though the neckline.
Another difference between the head and shoulders top and bottom is that the top formations are completed in a few weeks, whereas a major bottom (left, right shoulder or the head) usually takes longer, and as observed, may be prolonged for a period of several months or sometimes even more than a year.[4]
Importance of neckline edit
The neckline drawn on the pattern represents a support level, it cannot be assumed that a head and shoulder formation is complete unless the support level is broken. Such breakthrough may happen to be on greater volume or may not. Breakthroughs should be observed with great care. Serious drops can occur if a breakthrough is more than three to four percent of price.[citation needed]
When a stock drifts through the neckline on small volume, there may also be a wave up in some cases, although it has been observed that such a rally normally will not cross the general level of the neckline before selling pressure increases and a steep decline occurs, after which prices may due to greater volume.
Characteristics edit
- Most of the time, head and shoulders are not perfectly shaped. This formation is slightly tilted upward or downward.
- One shoulder may appear to droop.
- On many chart patterns, any one of the two shoulders may appear broader than the other which is caused by the time involved in the formation of the valleys.
- The neckline may not be perfectly horizontal; it may be ascending or descending.
- If the neckline is ascending, then to qualify as a head and shoulders formation, the lowest point of the right shoulder must be noticeably lower than the peak of the left shoulder.
Usage as a tool edit
Head and shoulders is a useful tool after its confirmation to estimate and measure the minimum probable extent of the subsequent move from the neckline. To find the distance of subsequent move, measure the vertical distance from the peak of the head to the neckline. Then measure this same distance down from the neckline beginning at the point where prices penetrate the neckline after the completion of the right shoulder. This gives the minimum objective of how far prices can decline after the completion of this top formation.[citation needed]
If the price advance preceding the head and shoulders top is not long, the subsequent price fall after its completion may be small as well.
Complex head and shoulders edit
This type of head and shoulders pattern has more than one left or right shoulders or head. It is also known as multiple head and shoulders pattern.[citation needed]
One particular type is known as a Wyckoff distribution, which usually consists of a head with two left shoulders and a weaker right shoulder.[citation needed]
