When Is a Dow Theory Breakout Confirmed?
Explain confirmation between the two Dow averages and identify what would invalidate a bullish interpretation.

Two averages, one claim
Imagine the industrial average has climbed above a prior important peak. A commentator calls it a new bull-market signal. Before accepting that claim, ask what the transportation average is doing. Dow Theory treats confirmation between these two averages as evidence that broad economic activity is participating, rather than relying on one index alone.

Why those averages?
Historically, the industrial average served as a proxy for production, while the transportation average reflected distribution. The idea was that stronger production should eventually be reflected in the movement of goods. Modern constituents are not a pure map of those roles, so treat this as the historical logic of confirmation.

Read the chart
Suppose the industrial average closes at 106 after its old peak at 100. The transportation average reaches 99, then turns down. The industrial breakout is real as a price event, but the pair has not confirmed it. The disciplined conclusion is “unconfirmed advance,” not “the trend must reverse.”

What counts as a meaningful test?
Compare important peaks or troughs on compatible time scales. A minor intraday move in one average should not be matched against a major monthly peak in the other. Dow Theory distinguishes primary trends from secondary reactions and shorter daily fluctuations, so the horizon of the claim matters.

Think before the answer
Checkpoint: both averages previously made important highs near 100. Industrials are now at 106; transportation briefly touched 101 intraday but closed at 99 and is falling. Would you call the pair confirmed? Pause and name the specific evidence you would need before answering.

The careful answer
No. The transportation average has not closed above its important prior high, so the two-average confirmation is absent. That does not prove a bear market or guarantee failure. It means the bullish interpretation remains less fully confirmed and should be stated with that limitation.

What would change the read?
If transportation later closes above its comparable prior high, the pair gains confirmation. If the industrial average falls back below its breakout area before that happens, the immediate breakout thesis weakens. A gap, revised data, or a different chosen swing can also affect interpretation, so document the chart and rule used.

A framework, not a forecast
The averages are price series with their own composition and history. They can diverge for long periods, and confirmation can arrive after part of a move has occurred. Use the theory to organize evidence about trend, not as a precise entry rule or a promise about economic conditions.

Take the method with you
First identify the two averages and the important comparable swing. Next check whether both have moved beyond their prior turning points. Finally label the result confirmed, unconfirmed, or weakened, and say what would change your view. Try the free practice questions for more CMT examples.
