BEARISH FLAG PATTERN – Part 1: Formation

Bearish Flag is a short term bearish continuation pattern that occurs during a downtrend, indicating a pause / small consolidation before continuing its downward moves.
This pattern normally appears following a sharp price decrease on high volume.

The Formation of Bearish Flag



Bearish Flag Pattern is usually preceded by a very steep (almost vertical) decrease in price on heavy volume. This steep price decrease makes the “Flagpole” of the pattern.
The sharp decline in price may occur due to negative market sentiments toward unfavorable events / developments, such as negative earning surprises, downward guidance, fraud / court cases, etc.

After the sharp decrease, the price movement is then contained within two parallel lines, forming a small rectangle “Flag” shape, on decreasing volume.
The rectangle flag is often slightly sloping upward, although it could be horizontal as well.
This flag represents a brief pause / consolidation in the midst of a downtrend before resuming its downward movement.

The completion of the pattern occurs when prices break to the downside through the support level (i.e. lower parallel line) of the Flag with a spike in volume. This would mark the resumption of the original downtrend.

The Psychology Behind Bearish Flag Pattern
A Bearish Flag pattern takes place because prices seldom decline sharply in a straight line for an extended period. Hence, during a sharp price movement, prices will typically take brief pause periods to "catch their breath" before continuing their move.

During the 1st stage of the Bearish Flag pattern (Flagpole part), as a result of negative market reactions toward some unfavorable events / developments (e.g. negative earnings surprises, downward guidance, etc.), prices keep on dropping sharply as nervous sellers and new short sellers who were caught-up in the euphoria at that moment, are willing to sell at even lower prices.

As the prices drop, some early sellers who have sold short the stock at higher levels would begin to cover their short position. In addition, some investors might also start bargain-hunting. At this point, the 2nd stage of the Bearish Flag pattern begins (i.e. the Flag part).
At first, most of the stocks bought by the early sellers were easily absorbed by nervous new sellers, since the news and market sentiments are still very negative. Nevertheless, as time passes, the selling pressures subside and more investors come for bargain hunting. Consequently, the prices begin to climb up gradually, but the increase is slow and volume is diminishing, as the bearish sentiment is actually still very strong.

After some time, just as it starts to look as if a real increase is underway, new negative news come out. As a result, the price begin to collapse again and break out through the lower line of the Flag with a surge in volume, as new sellers now overwhelm those bargain hunting.
In the following days, there might be more unfavorable news / comments or less optimistic earnings forecast coming, leading the prices to drop even lower.

BULLISH FLAG PATTERN – Part 2: Important Characteristics

Go back to Part 1: Bullish Flag Formation.

Important Characteristics of Bullish Flag Pattern

Shape of Bullish Flag:
1) Flagpole:
For Bullish Flag pattern to be more reliable, there should be a very sharp / steep price increase (almost vertical, and may contain gaps) on heavy volume that makes the “Flagpole” part of the pattern.
Without a steep price increase, the pattern might be less reliable and riskier.
2) Flag:
A Flag part of the pattern is formed when the price movement is contained within two parallel lines, representing a brief consolidation after the sharp increase.
This consolidation forms a small rectangle that frequently slopes against the preceding trend (i.e. the trend of the Flagpole part).
Therefore, in case of Bullish Flag, since the preceding trend is up, the rectangle flag often slightly slopes downward.
However, the Flag could be horizontal as well.

Volume:
Volume should be heavy during the formation of the Flagpole part, then decreasing during the formation of the Flag part, and the volume should spike when the price break out through the resistance of the upper parallel line of the Flag.
High volume during the breakout increases the chances of continuation of the preceding trend.
Without a volume spike on the breakout, the pattern might be less reliable.

During the formation of the Flag, if the volume remains constant or was even increasing, then the reliability of this pattern would be doubtful and might signal a trend reversal instead.

Duration:
The duration of the pattern depends on the price fluctuation during consolidation.
The greater the fluctuation, the longer a pattern will take to form.

On a daily chart, this pattern might take about 1 to 12 weeks to develop.
Ideally, this pattern should form between 1 and 4 weeks.
When the duration is between 4 and 12 weeks, the pattern might carry more risk. After 4 weeks, interest in the stock might have decreased and make it unlikely to continue in a strong uptrend.

When the duration is more than 12 weeks, it would be classified as a rectangle.

Breakout Direction:
For Bullish Flag pattern, the breakout should happen to the upside (i.e. breakout through the upper parallel line).
However, in some rare cases, the price might break against the previous trend, and create a reverse of trend. This reversal pattern may be signaled during the Flag formation by a significant increase in volume, instead of decreasing.

Potential Price Target:
1) Compute the height of the Flagpole.
The height of the Flagpole is the distance from the start (lowest point) of the sharp price increase to the end (highest point) of the increase. (See picture in Part 1).
2) Add the result to the bottom the Flag to get the Potential Price Target.

Return to Breakout Level:
After the breakout occurs, the price may sometimes return to breakout level for an immediate test of this support level. (Remember, the previous resistance level has now become support level).
However, if the price closes below this support level, the pattern could be considered invalid.
