Broadening Wedge, Descending
3 min read
Core idea
The descending broadening wedge is the mirror of the ascending version: two down-sloping trendlines that diverge, with the lower line falling more steeply than the upper. The pattern most often appears as either a consolidation in an existing uptrend — the corrective phase of a measured move up — or a reversal of an intermediate-term downtrend. Upward breakouts dominate at roughly 72% of cases, making it one of the few broadening patterns with a clear directional bias. Volume usually trends upward through the pattern (about two-thirds of the time), which is unusual for chart patterns and contributes to the upside thrust at breakout.
The shape's logic
Falling highs but even-faster-falling lows describe a market that is broadly selling but progressively more willing to bid back up. The widening swings mark increasing volatility around a decreasing-then-stabilizing baseline — the noise that often precedes a trend reversal or resumption.
Performance is below average
Despite the upside bias, the descending broadening wedge sits near the bottom of the performance rankings. Average rises after upward breakouts are modest, and the cumulative failure rates (18% fail to climb more than 5%, ~51% fail to clear 25%) make hitting big measure-rule targets unlikely. The redeeming quality: when a downward breakout busts (47% do), 75% become single-busts with average rises of 65%.
Why it matters
This pattern is a useful regime signal: if it appears mid-uptrend, treat the breakout as a continuation entry; if it appears after a downtrend, treat the breakout as a reversal. The volume trend is your tiebreaker — rising volume through a long, scrappy decline often catapults price out the top of the pattern even when the average move is modest. The lesson is to size positions to the modest move, not to the dramatic shape.
Key takeaways
Mental model
Practical application
Trading the upward breakout
-
Confirm context. Identify whether the wedge sits in an established uptrend (continuation) or after a downtrend (reversal). Either is tradeable, but knowing the regime helps with stop placement and exit expectations.
-
Check volume. Linear-regression the volume from start to end. Rising volume during a wedge that consolidates lower highs and lower lows is a meaningful bullish tell.
-
Wait for the breakout close. Price closing above the upper trendline. Avoid intra-bar fakeouts — wait for the close.
-
Set a modest profit target. The full measure-rule target rarely hits. Take partial profit at 1× pattern height and let the rest ride to a trailing stop.
-
Stop below the most recent minor low inside the pattern. A reversal back through that level kills the thesis.
When to skip it
Example
A consumer-staples stock has rallied from $50 to $80 over a year, then enters a four-month corrective phase. Highs print at $78, $74, $69, $64; lows print at $72, $66, $58, $51. A descending broadening wedge forms. Volume trends upward through the four months — unusual for a stock that's declining.
In month five, price closes above the upper trendline at $66 on heavy volume. A trader enters long with a stop at $51 (below the lower trendline) and a first profit-target at the pattern height ($78 − $51 = $27) added to the breakout price → $93. Half the position is closed at $93 four months later; the remainder rides a trailing stop and exits at $98 after a brief throwback.
Total return: ~45% on the position, in line with the pattern's ~39% average — modest enough that position-sizing relative to portfolio risk mattered more than picking the perfect entry.
