Breakouts, pullbacks and retests

In simple terms

A breakout happens when a price moves above a resistance zone it has failed to pass before. A breakdown happens when it moves below a support zone. Traders watch for them because a move through a level that has held several times may mean the balance between buyers and sellers has changed.

Breakouts are popular in trading courses and tip groups. They are also one of the most common sources of losses, because many of them fail.

Defining a breakout

"Moving above resistance" is vague: does a single trade above the zone count? A wick that pokes above and closes back inside? Define a breakout by a rule, for example:

• a close (not an intraday high) above the top of the resistance zone,
• by at least a set percentage, such as 1% or 2%, or by a multiple of the average true range,
• on the timeframe you are analysing.

A clear rule makes the breakout an observation that you, or anyone else, could check, and lets you test how breakouts defined that way have performed.

Pullbacks and retests

After a breakout, prices often fall back towards the broken level. This is a pullback. If buyers appear near the old resistance, it has acted as support, the role reversal described in the support and resistance lesson. Traders call this a retest.

What volume adds

Volume on a breakout day well above the share's average shows that many shares traded at the new prices, which suggests broad participation rather than a few orders. That is useful information. But:

• volume does not show who was buying, or that buyers outnumbered sellers, as the volume lesson explains;
• high-volume breakouts also fail;
• volume can be inflated by index changes, block deals or circular trading.

Treat volume as context, not confirmation.

A breakout as a hypothesis

The disciplined way to think about a breakout is as a testable idea:

1. Observation: the price closed above resistance by your rule.
2. Hypothesis: the balance has shifted towards buyers, and the price may continue higher.
3. Invalidation: if the price closes back below the zone, the hypothesis is wrong.
4. Plan: what you would do at each point, including the size of any position and the loss you would accept, as the entry and exit planning and position size lessons explain.

Writing these down before acting stops you from explaining away a failed breakout afterwards.

Thinly traded shares

In shares with little volume, a single buyer can push the price through resistance. Pump-and-dump operators use apparent breakouts to attract buyers, as the pump-and-dump lesson explains. Be especially sceptical of breakouts in small, illiquid shares promoted in tip groups.

Why it matters

Breakouts are one of the most widely taught chart signals, so understanding how to define them, what volume does and does not add, and how often they fail is essential. Treating every breakout as a hypothesis with an exit point limits the damage when, as often happens, it fails.

Limitations

Breakout definitions are choices, and results depend heavily on them. Past breakouts that worked are easy to find on charts; those that failed are easy to forget. No rule turns breakouts into reliable predictions. The false breakouts lesson looks at failure in detail.

Common mistakes

• Treating an intraday poke above resistance as a breakout.
• Assuming high volume makes a breakout reliable.
• Having no invalidation point.
• Chasing breakouts in thinly traded or promoted shares.

Try it yourself

1. Find three shares on a daily chart that broke above a clear resistance zone in the past year, by a 2% closing rule.
2. For each, note volume on the breakout day relative to its 20-day average.
3. Record what happened over the next 20 sessions: follow-through, retest, or failure back into the zone.
4. Then find three more breakouts you did not choose by hindsight, for example the first three you find in a list of shares, and repeat.
