Breakdown Below SMA
This setup identifies stocks that have broken decisively below a moving average that previously supported the trend. The first real loss of a key average is often how a trend change announces itself, converting former support into overhead resistance.

What has to be true for a Breakdown Below SMA to trigger
- A prior uptrend with the average acting as support
- A decisive close below the average rather than a brief poke beneath it
- The break confirmed rather than immediately recovered
How PatternGrade grades it
A more decisive break of a more significant average, after a better-established uptrend, raises 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 Breakdown Below SMA looks like in practice
A stock has held its 50-day average on four separate pullbacks over five months. On the fifth test it does not hold: price closes at $61.40 against an average at $63.80, on volume 2.4 times average and a session that closes near its low. Over the following two weeks it bounces back to $63.50, fails at the average that had supported it, and turns down again.
How a Breakdown Below SMA fails
Price reclaims the average within a few sessions and the trend resumes. Single closes below a moving average are common and mean very little on their own. A stock in an uptrend will dip below its 50-day several times a year without consequence. The pattern only carries weight when the break is decisive, on volume, and followed by a failed retest from below.
What this pattern is telling you
Moving averages are broken and reclaimed constantly in choppy markets. A single break is weak evidence without follow-through.

How to scan for Breakdown Below SMA 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.

Breakdown Below SMA FAQ
What does breaking below the 200-day moving average mean?
A widely watched long-term trend reference has been lost. It is read as a trend deterioration signal, though single breaks are frequently reclaimed.
Which moving average matters most for a breakdown?
The one the stock has actually been respecting. The 50-day is the most-watched for swing horizons and the 200-day for longer ones, but an average the stock has ignored for months is not support, and losing it is not a signal. PatternGrade weights how well the average was respected before the break.
How decisive does the break need to be?
More than a marginal close beneath. PatternGrade scales the threshold to the stock's own volatility rather than using a fixed percentage, since the same absolute distance means very different things on a quiet large-cap and a volatile small-cap.
What confirms a moving-average breakdown?
A failed retest: price bounces back to the average from underneath and turns down there. That reversal of roles from support to resistance is the strongest confirmation the break was real, and it is what separates a breakdown from an ordinary dip.
Does the average need to be falling?
Not at the moment of the break, but a breakdown below an average that then rolls over is far more significant than one below an average that keeps rising. The slope in the following weeks is what distinguishes a genuine trend change from a shakeout.
Patterns a Breakdown Below SMA is mistaken for
- Pullback to SMA
- The bullish counterpart, and what this pattern becomes if the average holds. They sit on either side of the same line.
- Death Cross
- A death cross is two averages crossing each other. This is price losing one average.
- Stage 4 Downtrend
- Stage 4 is a sustained regime below a falling long-term average. A breakdown is the event that can begin it.
- Distribution Day
- A distribution day is defined by a decline on heavier volume, with no reference to any average. The two often coincide.
