Pennant Pattern
A Pennant is a small symmetrical triangle that forms after a sharp price move — called the “flagpole”. The brief consolidation that follows looks like a small triangular pennant. Pennants are short-term continuation patterns that often complete in a few sessions and signal that the prior strong move is likely to resume.
Key takeaways:
- Pennants form after a sharp, near-vertical price move (the flagpole).
- They are short-duration symmetrical triangles, typically 1–3 weeks.
- Volume contracts within the pennant and surges on the breakout.
- Continuation pattern — bullish pennant resolves up, bearish resolves down.
- Target = the length of the flagpole, projected from the breakout.
Anatomy of a Pennant
- Flagpole: Sharp, sustained move in one direction with strong volume.
- Pennant body: A brief symmetrical triangle as price pauses.
- Volume contraction: Volume falls during the pennant formation.
- Breakout: Price exits the pennant in the direction of the flagpole, with renewed volume.
Why pennants work
A sharp move often runs out of fuel temporarily. Traders take profits, new entrants wait for a pullback, and the price drifts sideways. As soon as enough fresh demand (or supply) returns, the original momentum resumes. The pennant is the visual signature of this pause-and-continue cycle.
Trading a Pennant
- Identify the flagpole — a sharp move on strong volume.
- Wait for a short consolidation that narrows into a symmetrical triangle.
- Enter on a breakout in the direction of the flagpole, ideally with volume confirmation.
- Project the target by adding the flagpole’s length to the breakout price (or subtracting for shorts).
- Place stops on the opposite side of the pennant.
Pennant vs Flag
| Pennant | Flag |
|---|---|
| Symmetrical triangle shape | Parallel channel shape |
| Converging trendlines | Parallel trendlines slope against the flagpole |
| Brief consolidation | Slightly longer than pennants |
Common pitfalls
- Treating a long sideways range as a pennant. Pennants are brief.
- Trading without volume confirmation. Pennants that break without a volume surge often fail.
- Missing the initial flagpole. A pennant without a flagpole is just a small triangle.
- Holding through the entire flagpole projection without managing risk.
Indian market examples
Pennants frequently appear in F&O charts of high-momentum stocks after results, news, or sector-wide moves. Bullish pennants in banking sector leaders during a rally often signal continuation legs of 5–10%. Combine with sector strength and broader market trend for higher-probability setups.
Frequently asked questions
How long should a pennant last?
Usually 1–3 weeks. Longer pauses become symmetrical triangles or rectangles.
Should the flagpole always be vertical?
It should be a sharp move, but it does not need to be perfectly vertical.
What if the breakout is in the opposite direction?
Treat it as a failed pattern — the original move may be reversing.
Can pennants form intraday?
Yes, particularly on news-driven days. Intraday pennants are common in F&O scalp setups.
