The head and shoulders pattern
The head and shoulders pattern is a
common technical analysis chart formation that signals a potential trend
reversal in a financial market, typically occurring after a bullish trend.
Recognized by its distinctive shape, this pattern is named for its resemblance
to a person’s head and shoulders. It consists of three peaks: a central, higher
peak (the “head”) and two smaller peaks on either side (the “shoulders”). This
pattern can be used to indicate that a stock or other asset's price has reached
its peak and may start to decline, making it valuable for traders aiming to
identify optimal points for selling or shorting.
Formation of the Head and Shoulders Pattern
- Left Shoulder:
After a prolonged upward trend, the price reaches a peak and then declines
to a local low, forming the first "shoulder."
- Head:
The price rises again, usually to a higher peak than the first, and then
falls back down again. This second, higher peak is the “head” of the
pattern.
- Right Shoulder:
The price rises once more but fails to reach the height of the “head,”
creating the second “shoulder.” After reaching this peak, the price
typically begins to drop once more, often breaking the
"neckline."
The neckline is a key feature
of the head and shoulders pattern. It is formed by drawing a line that connects
the two low points between the shoulders and the head. This line often serves
as a level of support in an uptrend. When the price breaks below the neckline,
it typically signals a more significant trend reversal, as buyers lose control
and sellers take over. The neckline’s slope can vary, but a downward slope is
often more bearish.
Inverse Head and Shoulders Pattern
An inverse (or "inverse head
and shoulders") pattern is a mirror image of the standard head and
shoulders and indicates a potential trend reversal from bearish to bullish.
Here, the price forms a low (left shoulder), followed by a lower low (head),
and then a higher low (right shoulder), before breaking above the neckline.
This pattern suggests that sellers are losing momentum, and a bullish reversal
may be on the horizon.
Key Points and Trading Strategy
- Volume Analysis:
Volume is often highest during the formation of the left shoulder,
decreases through the head, and remains low at the right shoulder. An
increase in volume when the neckline breaks is a strong confirmation of
the pattern.
- Entry Point:
Many traders choose to enter a trade once the price breaks through the
neckline, confirming the trend reversal.
- Target Price:
The estimated target price for the move after the breakout can be
calculated by measuring the distance from the neckline to the head. This
distance is then projected downward (for head and shoulders) or upward
(for inverse) from the breakout point.
- Stop Loss:
A stop-loss order is commonly placed just above the right shoulder in a
standard head and shoulders to limit potential losses in case of a failed
pattern.
Limitations
The head and shoulders pattern,
while useful, is not foolproof. False breakouts can occur, where the price
briefly moves beyond the neckline but quickly reverses back, trapping traders
in unfavorable positions. Additionally, while volume can support the
reliability of the pattern, it is not always consistent, making it essential
for traders to combine this pattern with other technical indicators or price
action for confirmation.
Practical Example
Imagine a stock in a bullish trend
that forms a peak at $50 (left shoulder), then another higher peak at $55
(head), and a lower peak at $52 (right shoulder). The neckline connecting the
two lows is at $48. If the stock breaks below this neckline, a target of around
$43 might be projected (taking the $5 difference between the head and
neckline). This target can help traders plan entries, exits, and stop losses
for maximum advantage.
In summary, the head and shoulders pattern is a versatile tool for identifying trend reversals. By understanding its structure, significance, and strategy, traders can leverage it to make informed decisions and manage risks effectively.
