Bear Flag
A bear flag is the downside mirror of the bull flag: a steep decline (the pole) followed by a shallow consolidation that drifts up against the move. It represents a pause in which short covering lifts price without new buyers taking control.

What has to be true for a Bear Flag to trigger
- A steep, high-volume decline forming the pole
- A shallow consolidation drifting against it
- The bounce retracing only part of the pole
- Volume contracting through the flag
How PatternGrade grades it
A cleaner pole, a tighter and shallower flag, and clearer volume contraction raise the grade.
Every scanner grades its hits A+, A or B from the pattern's own measurable structure. The grading is deterministic — the same chart always produces the same grade. It describes how closely the chart matches the pattern, not how likely anything is to happen; no hit rate or probability is attached to a grade. The reasoning is set out in the methodology.
What a Bear Flag looks like in practice
A stock drops 22% in five sessions on volume four times average. That is the pole. Over the next eight sessions it grinds back up about 6%, each day's range narrower than the last, on volume fading toward average. The bounce recovers less than a third of the decline and rolls over from just beneath a moving average it lost on the way down.
How a Bear Flag fails
The bounce keeps going. Recover more than about half the pole and the pattern has lost its meaning. The sellers who drove the decline have been fully offset, and what looked like a pause is a reversal. Bear flags in oversold, sharply-declining markets are especially prone to this, because the sharpest rallies happen in downtrends.
What this pattern is telling you
In a strong market, bear flags fail regularly. A shallow drift higher on light volume is also what the start of a genuine recovery looks like.

How to scan for Bear Flag setups
PatternGrade rescans every liquid US stock (~4,500 names) for this pattern after every close and returns the hits as a graded list, with the pattern drawn on each chart, so you review setups rather than hunt for them.

Bear Flag FAQ
What is a bear flag pattern?
A sharp decline followed by a shallow upward drift on lighter volume. It is a continuation pattern that conventionally resolves lower.
How far should a bear flag retrace?
Ideally no more than a third of the pole, and rarely more than half. The point is that the decline was barely recovered: short covering without genuine buying. Past the halfway mark the structure reads as a reversal, and PatternGrade's grade falls off sharply with retrace depth.
How long does a bear flag last?
Usually one to three weeks on daily bars. Flags are brief by nature. A consolidation running past about four weeks has generally stopped being a flag and become a base, which carries the opposite implication.
What volume should a bear flag show?
Heavy on the pole, lighter through the flag. Volume expanding on the up days inside the flag is the main disqualifier. It suggests real buying rather than short covering, and it is weighted heavily in the grade.
Are bear flags harder to trade than bull flags?
In practice, often yes. Downtrends produce sharper counter-trend rallies than uptrends produce pullbacks, so the consolidation is noisier, and short positions carry borrow costs and unbounded upside risk. The geometry is symmetric; the trading is not.
Patterns a Bear Flag is mistaken for
- Bull Flag
- Identical geometry inverted: a sharp advance followed by a drift down. Pole direction is the only difference.
- Bearish Pennant
- A pennant's boundaries converge; a flag's are roughly parallel. Same pole, different consolidation shape.
- Rising Wedge Breakdown
- A rising wedge is a longer converging advance with no pole requirement. A bear flag is a brief drift after a specific sharp decline.
- New Low Bounce
- A dead cat bounce follows a large event-driven collapse and is about the bounce failing. A bear flag is a tighter, more orderly consolidation and can occur in any downtrend.
