Distribution Day
A distribution day is a session with a meaningful decline on volume heavier than the day before. The combination of price down and volume up is the signature of institutional selling, since large sellers cannot exit without leaving a volume footprint. Clusters of distribution days are a classic warning sign.

What has to be true for a Distribution Day to trigger
- A meaningful decline on the session
- Volume heavier than the previous session
- The decline exceeding a noise threshold rather than a fractional dip
How PatternGrade grades it
A larger decline on heavier relative volume grades higher.
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 Distribution Day looks like in practice
A stock closes down 1.8% at $88.20 on 3.1 million shares, against a prior session's 2.2 million and a 50-day average of 1.9 million. The decline is not dramatic, but it happens on the heaviest volume in three weeks and the close lands near the session low. Three similar sessions occur within the following four weeks.
How a Distribution Day fails
A single distribution day means almost nothing. Individual heavy down sessions occur constantly, around news, expirations and rebalancing, and reading each one as institutional selling produces a stream of false alarms. The pattern only becomes informative as a count over a window, and even then it is a warning about supply rather than a directional signal.
What this pattern is telling you
One distribution day means little. The signal is in the clustering, several within a few weeks, which is a judgement about the market rather than a single stock.
PatternGrade is not a financial advisor and does not give buy or sell recommendations. Targets and stops shown on a pattern are reference levels derived from its geometry, not advice.
How to scan for Distribution Day 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.

Distribution Day FAQ
What is a distribution day?
A session where price falls meaningfully on volume heavier than the prior day, read as institutional selling, since large sellers leave a volume footprint.
What is a distribution day?
A session where the stock or index declines meaningfully on volume heavier than the previous session: the footprint of large holders selling into the market. The concept comes from William O'Neil's work and is most commonly applied to market indices as a breadth warning.
How many distribution days signal trouble?
The conventional threshold is four or five within a rolling four-to-five week window. That is a convention rather than a rule, and it was developed for index analysis. On individual stocks the count is noisier and should be read alongside the price structure.
How much does the price need to fall?
Conventionally at least a modest fraction of a percent, enough that it is a real decline rather than a flat close. The specific threshold matters less than the pairing of a genuine down day with elevated volume.
Do distribution days expire?
Yes, in the conventional treatment they roll off after about 25 sessions, and are also considered cancelled if the index or stock advances substantially from the level where they occurred. Without that expiry the count would only ever accumulate.
Patterns a Distribution Day is mistaken for
- Relative Volume
- RVOL flags unusual volume in either direction. A distribution day specifically requires a price decline on volume heavier than the prior session.
- Pocket Pivot
- The conceptual opposite: an up day on volume exceeding recent down-day volume. Together they describe institutional footprints in a base.
- Gap Down
- A gap down is defined by the open relative to the prior low. A distribution day needs no gap and is defined by close and volume.
- Breakdown Below SMA
- A breakdown references a specific average. Distribution days reference only volume and direction, and often accumulate before any average is lost.
