ANALYZING CHART PATTERNS: HEAD AND SHOULDERS
The head-and-shoulders pattern is one of the most
popular and reliable chart patterns in technical analysis. And as one might
imagine from the name, the pattern looks like a head with two shoulders.
Head and shoulders is a reversal pattern that, when
formed, signals the security is likely to move against the previous trend.
There are two versions of the head-and-shoulders pattern. The
head-and-shoulders top is a signal that a security's price is set to fall, once
the pattern is complete, and is usually formed at the peak of an upward trend.
The second version, the head-and-shoulders bottom (also known as inverse head
and shoulders), signals that a security's price is set to rise and usually
forms during a downward trend.
Both of these head and shoulders have a similar
construction in that there are four main parts to the head-and-shoulder chart
pattern: two shoulders, a head and a neckline. The patterns are confirmed when
the neckline is broken, after the formation of the second shoulder.
The head and shoulders are sets of peaks and troughs.
The neckline is a level of support or resistance. The head and shoulders
pattern is based on Dow Theory's peak-and-trough analysis. An upward trend, for
example, is seen as a period of successive rising peaks and rising troughs. A
downward trend, on the other hand, is a period of falling peaks and troughs.
The head-and-shoulders pattern illustrates a weakening in a trend where there
is deterioration in the peaks and troughs.
Head and Shoulders Top
Again, the head-and-shoulders top signals to chart users
that a security's price is likely to make a downward move, especially after it
breaks below the neckline of the pattern. Due to this pattern forming mostly at
the peaks of upward trends, it is considered to be a trend-reversal pattern, as
the security heads down after the pattern's completion.
This pattern has four main
steps for it to complete itself and signal the reversal. The first step is the
formation of the left shoulder, which is formed when the security reaches a new
high and retraces to a new low. The second step is the formation of the head,
which occurs when the security reaches a higher high, then retraces back near
the low formed in the left shoulder. The third step is the formation of the
right shoulder, which is formed with a high that is lower than the high formed
in the head but is again followed by a retracement back to the low of the left
shoulder. The pattern is complete once the price falls below the neckline,
which is a support line formed at the level of the lows reached at each of the
three retracements mentioned above.
