Bear Pennant Pattern: Tight Coil After a Decline

Key Takeaways

• A bear pennant pairs a steep downward flagpole with a small symmetric triangle that compresses price into a tight apex.
• The pattern lasts no more than about three weeks, longer formations are treated as full symmetric triangles instead.
• The most common mistake is shorting inside the coil before a confirmed close below the lower trendline.
• The measure rule projects the flagpole height from the breakdown to set a downside target.

What It Is

A bear pennant has two parts. The flagpole is a sharp decline, usually a 20% drop or more, that establishes the downtrend. The pennant is the consolidation that follows, drawn as two converging trendlines, one connecting lower highs and one connecting higher lows.

The figure looks like a small triangular flag hanging from a vertical line. Without the prior decline, the same coil is just a generic symmetric triangle and has no built in directional bias.

The Intuition

After a steep drop, short term traders cover their positions and dip buyers test the lows. Both sides become less aggressive over time, so the range tightens from both directions at once. Volume falls during the indecision, then surges when the dominant trend reasserts itself and the original sellers return.

The shape tells you that supply has not gone away, the market is just briefly catching its breath. The tighter the coil and the lighter the volume during the build, the stronger the case for continuation.

How It Works

A textbook bear pennant has these features. The flagpole loses 20% or more in a short window, often a few days to two weeks. The pennant is built from at least two lower highs and two higher lows over no more than three weeks. Volume drops sharply through the consolidation, often more than in any other continuation pattern.

The measure rule sets the target:

Target = Breakdown price - (Top of flagpole - Base of flagpole)

Confirmation requires a close below the lower trendline on volume above the recent average. Many traders wait for two consecutive closes below the line or apply a percentage filter to limit false breaks.

If the pennant retraces more than 50% of the flagpole, the pattern is weakened. A deep bounce signals the prior sellers may have backed off, and the continuation read becomes less reliable.

Worked Example

A stock falls from 120 to 90 over eight sessions, a 25% drop on rising volume. Over the next two weeks it prints lower highs at 96, 94.50, and 93, with higher lows at 90, 91.50, and 92. Volume on the consolidation is about 40% of the decline average.

Price closes at 91.20 on volume 90% above its 50-day mean, breaking the lower trendline. Flagpole height is 30 points, giving a measure rule target of 91.20 minus 30, or 61.20. A short entered at 91.20 with a stop at 93.50, just above the most recent lower high, risks 2.30 for a reward of 30, well over ten to one.

Common Mistakes

1. No flagpole, no pennant. A coil without a preceding sharp decline is just a small triangle. The pole is what gives the pattern its bearish bias.
2. Shorting inside the coil. The setup confirms only on the breakdown. Selling at the upper line is a different trade with no statistical edge from this pattern.
3. Letting the pennant run too long. A coil that drags on past three weeks loses its pennant character. Bulkowski treats those as full triangles with their own statistics.
4. Skipping volume. A coil that compresses on rising volume is suspect. Visibly drying volume through the build is part of the textbook pattern.
5. Setting stops at obvious points. Placing a stop one tick above the upper trendline ignores normal noise. Use a buffer above the last lower high or an average true range stop.

Frequently Asked Questions

What is a bear pennant pattern in simple terms? It is a brief tight coil that forms after a sharp drop and usually breaks lower. The shape is a small symmetric triangle with converging trendlines.

How does a bear pennant pattern affect investment decisions? A confirmed breakdown below the coil gives a short entry, a stop above the most recent lower high, and a measured target equal to the flagpole height. For long-only investors it is also a clean exit signal.

What is a real-world example of a bear pennant pattern? Stocks reacting to a downgrade or guidance cut often print bear pennants. The flagpole is the news day drop, and the pennant is a quick coil before the next decline.

How can investors trade the bear pennant pattern effectively? Require a clear flagpole, a coil lasting no more than three weeks, a close below the lower line on heavier volume, and a flagpole-based target.

How is a bear pennant different from a bear flag? A bear flag has parallel trendlines sloping slightly upward. A bear pennant has converging trendlines forming a small symmetric triangle. Same setup, different geometry.
