Distribution days are down days that trade on heavier volume than the session before — and a cluster of them over a few weeks is one of the earliest signs that a rising market is topping before the high actually prints. They measure something a price chart alone hides: large holders quietly selling while the index still looks healthy. Gary Glover (AR 259215), Authorised Representative of Novus Capital Limited (AFSL 238 168), who reviews ASX momentum stocks in a recorded weekly session with Finer Market Points, counted roughly seven of them on the Nasdaq in the three-to-four weeks to his 30 June 2026 session. This guide explains the exact rule for a distribution day, how many is a genuine warning, what the 2000, 2007 and 2021 market tops revealed, the tells that confirm a forming top, why money rotates rather than leaves, and how ASX momentum traders should read it.
What is a distribution day, and how does it signal a market top?
A distribution day is a down close on volume heavier than the previous session — the fingerprint of institutions selling into a rising market. Investor's Business Daily (IBD), building on William O'Neil's CAN SLIM methodology, gives the concept a precise definition: the Nasdaq Composite or S&P 500 closes down at least 0.2% on volume higher than the prior session. The detail that surprises most traders is that the volume does not need to be above average — only above the day before.
The concept is the "M" — Market Direction — in O'Neil's seven-factor CAN SLIM framework, documented in How to Make Money in Stocks (2009). Rather than guess at a top, O'Neil and IBD count heavy-volume down days to read whether the general market is under accumulation or distribution.
The signal is best understood as the mirror image of its opposite:
- Accumulation — an up day on heavier volume. Institutions are building positions; demand is winning.
- Distribution — a down day (at least 0.2%) on volume above the prior session. Institutions are trimming; supply is winning.
- The shift that matters — when a market that had been making progress on accumulation starts stacking up distribution days, the character of the buying has changed from strong hands adding to strong hands stepping back.
A distribution day is not permanent. Under IBD's method, a distribution day expires after 25 trading sessions, or sooner if the index trades 5% above that day's closing price intraday — the count is a rolling, self-clearing tally, not a running total since the high. That rolling window is what makes a cluster meaningful: several heavy-volume down days inside the same 25-session window is the counter-signal to a healthy uptrend, the first evidence that the move is being sold into rather than bought. It is why O'Neil treated the distribution-day count as a core read on US index health that sits alongside resistance analysis.
Gary Glover's anecdotal observation from the 30 June 2026 session matches the rule: a session down only a fraction of a percent still counts when it trades on more volume than the day before. This is a practitioner observation consistent with the documented IBD threshold, not a formal study of his own.
How many distribution days signal a market top?
Distribution days are not a single-day sell signal — O'Neil's method treats them as evidence accumulation. One heavy-volume down day can be noise. The number, and the window it falls in, is what turns noise into a warning.
IBD's practical danger zone is four to five definite distribution days over roughly four to five weeks. More recent IBD guidance is that markets often roll over after six or seven distribution days within 25 sessions, though an uptrend sometimes survives eight or more. The thresholds are a rising-risk scale, not a precise trigger:
- 1–3 days — background noise; an uptrend absorbs these routinely.
- 4–5 days in 4–5 weeks — IBD's classic warning zone; raise caution.
- 6–7 days in 25 sessions — the uptrend is often under real pressure or rolling into a correction.
- 8+ — elevated, though not an automatic top; some uptrends survive.
Set against that scale, Gary noted during the 30 June 2026 session that the three major US indices were not behaving alike:
US index | Distribution days (last 3–4 weeks) | Range behaviour | Read |
Nasdaq | ~7 | Widening | Most extended — inside IBD's "often rolls over" zone |
S&P 500 | 4 | Narrower | At the lower warning edge |
Dow Jones | ~0 | Calm, near ~52,000 | Holding; old-economy names steady |
The divergence is the more useful signal. When one index distributes heavily while another stays calm, it points to rotation between parts of the market rather than a wholesale exit from it. Gary observed that the Dow had shown neither the distribution nor the volatility expansion visible in the Nasdaq, and was holding beneath the ~52,000 level — behaviour consistent with capital favouring older, value-oriented names rather than abandoning equities altogether. That sets up the question of where the money goes, addressed below.
What did past market tops reveal about distribution days?
The method has a documented track record across three of the most-studied US market tops — and in each case distribution showed before the deeper damage. O'Neil's own writing and IBD's market-top education use these as canonical examples.
March 2000 — the Nasdaq dot-com top
In How to Make Money in Stocks (2009), O'Neil describes IBD flagging the March 2000 Nasdaq top through a sequence of distribution and churning signals. According to StatMuse market data and O'Neil's account, the sequence ran:
Date | O'Neil / IBD read | Nasdaq close | Volume |
7 Mar 2000 | First lower close on higher volume in 6+ weeks — the first yellow flag | 4,907.35 (−2.8%) | Above prior session |
10 Mar 2000 | New intraday high, then reversed to finish only slightly higher on heavy volume ~13% above average — "churning"; the dot-com peak | 5,048.62 | 1.992bn |
14 Mar 2000 | Down ~4% on a large volume increase — the third major warning | 4,706.63 | 1.978bn |
28 Mar 2000 | Suspect rally stalls again — a fourth distribution day | 4,833.89 | 1.490bn |
30 Mar 2000 | Rolls over on heavier volume — a fifth distribution day, confirming the 10 March top | 4,457.89 | 1.926bn |
The angle that matters: O'Neil was not claiming to call the exact top on 10 March. The method read progressive institutional selling and churning after the peak, giving sell-and-raise-cash evidence well before the deeper collapse.
October 2007 — the pre-GFC top
IBD's market-top education uses the 2007 Nasdaq top as a canonical distribution-day chart. O'Neil writes that IBD's Market Pulse showed five distribution days, switched the market outlook to "Market in correction", and suggested raising cash before the 2008 collapse:
The 2007 market top "began with at least five distribution days in October of 2007."
— William O'Neil, How to Make Money in Stocks (2009)
A separate IBD account notes five distribution days were on the count by 31 October 2007, roughly two weeks before the Nasdaq's late-October top. This is the cleanest "IBD said it in real time" example: five distribution days, the Market Pulse status changed, raise cash.
September 2021 — the stalling warning before the 2022 bear
The modern version of the signal includes not only classic down-volume days but also stalling days — heavy volume with little upward progress and a weak close. IBD's later analysis dates the warning to 1 September 2021, when the Nasdaq rose but closed near the day's lows while volume rose about 1.4% from the prior session — a stalling signal that gave roughly three trading sessions before the next leg lower began on 8 September 2021. According to StatMuse data, the Nasdaq fell 5.6% over September 2021 (closing 14,448.58 on 30 September on 5.951bn volume), and the S&P 500 fell 4.9% (closing 4,307.54 on 30 September).
Across all three tops, the pattern is consistent — distribution and stalling appeared while the index still looked strong:
Market top | Distribution signal (O'Neil / IBD) | What followed |
Nasdaq, March 2000 | ~5 distribution days, with churning at the 5,048 peak | Dot-com collapse |
Nasdaq, October 2007 | 5 distribution days by 31 Oct → Market Pulse "Market in correction" | 2008 bear market |
Nasdaq, September 2021 | Stalling day 1 Sep (heavy volume, weak close) → 3 sessions' warning | Nasdaq −5.6% in September; 2022 bear |

What other signs confirm a top is forming before the high?
Distribution days rarely arrive alone — Gary watches for several confirming tells before he treats a top as a live risk. Gary Glover's anecdotal observation, developed across his trading career, is that the cleanest warnings come when the distribution count is joined by these structural changes:
- Volatility expansion — daily ranges widening rather than tightening. A healthy trend tends to coil; ranges that start swinging wider are a late-cycle tell.
- Overlapping or churning price — back-and-forth bars at resistance where the market stops leaving clean space above prior highs. This is the overlapping-high topping signal Gary associates with distribution rather than continuation — and it is the same "churning" O'Neil flagged at the March 2000 peak.
- Stalling days — heavy volume with little upward progress and a weak close, the subtle distribution variant IBD read before the September 2021 decline.
- Flattening moving averages — longer-term averages losing their slope and overlapping one another, as on the ASX 200, which has spent recent weeks travelling sideways inside its band with its longer EMAs flat and tangled.
Context matters for how reliable these tells are. Gary observed that high-inflation environments produce more frequent false breaks — marginal breaks of prior highs and lows that reverse — a pattern visible in both the 1940s and 1970s and again across recent ASX price action. The lesson there is a historical one, examined in detail in what the 1940s and 1970s teach Australian investors. The Nasdaq is showing the widening ranges; the Dow is not — which is why Gary reads the topping risk as specific to growth, not the whole market.
Why does money rotate from growth to value when a top forms — instead of leaving the market?
A topping growth index is not the same as a falling market — Gary's anecdotal observation is that capital rotates rather than leaves. He pointed to the precedent: after the March 2000 Nasdaq high, value shares rallied roughly 11% over the following twelve-to-fifteen months while the Nasdaq itself fell hard. The Dow's current calm, set against the Nasdaq's distribution, is consistent with the same dynamic beginning again — money favouring what is cheap and steady over what is extended.
Where that money has tended to go is into two buckets: low-PE, higher-yielding value names, and beaten-down large caps near the bottom of their year — the "dogs of the Dow" effect, where the year's worst performers can turn at the end of the financial year. Gary discussed several illustrative names from the session:
Stock | What Gary noted (30 June 2026) | The evergreen lesson |
Harvey Norman (ASX: HVN) | Building above shorter-term averages; property-backed balance sheet | Value with asset support tends to firm first |
JB Hi-Fi (ASX: JBH) | From above $120, roughly a 50% retracement; three broken accelerating trend lines pointing to ~$85 as a minimum | Broken trend lines define a downside target, not a buy |
CSL (ASX: CSL) | From ~$280 early in 2026 to ~$100; P/E compressed to ~10–11, yield ~4.5% | A growth name can re-rate as a value share as spending falls |
Cochlear (ASX: COH) / Clinuvel (ASX: CUV) | Healthcare names showing early accumulation | Heavily sold sectors base before they run |
Telstra (ASX: TLS) | The FY2018 "dog" — down ~30–40% one year, then up ~30–35% the next | End-of-year weakness can mark a turning point |
These are dated illustrations of a pattern, not recommendations, and the figures are Gary's session observations. The flip side of the same coin is that the most-extended AI and growth infrastructure leaders are exactly where the distribution tends to show up first. That dynamic is why the move is best read as sector rotation rather than a market-wide top. Whether a beaten-down name is a genuine opportunity or a value trap is a separate question that a low multiple alone does not answer.
How should ASX momentum traders read US distribution — without calling the top?
Distribution is a risk gauge, not a sell signal — and Gary was explicit the high is not yet in. The IBD reading of past tops never tried to pick the exact peak; it raised cash as the evidence built. Gary noted during the 30 June 2026 session that the market could still see one more leg up; the disciplined response is to raise caution and lean harder on relative strength, not to liquidate on a count.
The seasonal map reinforces patience over panic. Gary's anecdotal observation is that midterm election years tend to put in a low around late June or early July, run into August, then pull back toward an October low — and that October midterm-year lows show weakness in something like nine of ten cycles. A top forming now would need roughly two-to-three months to run into that window. This is an illustration of how the pattern tends to unfold, not a forecast of a particular outcome.
For ASX momentum traders, the practical takeaways are:
- Trade only genuine relative strength — names holding firm or advancing while the index distributes.
- Size down while the risk gauge is elevated; respect a sideways ASX rather than forcing trades into it.
- Raise cash on the evidence, not the calendar — the lesson of 2000, 2007 and 2021 is that the count builds before the break, so a rising tally is the trigger to lighten, not a forecast of the exact day.
- Treat sitting out as a position when quality setups are absent — and watch whether a catalyst arrives near resistance, the configuration in which a catalyst can mark a top.
Conclusion
Distribution days are a volume-based early read on a forming top: under IBD's rule, a close down at least 0.2% on volume above the prior session, counted over a rolling 25-session window. Four or five in a few weeks is a warning; six or seven is often a market under real pressure. The method warned before the 2000, 2007 and 2021 tops, and the current picture is a divergence — the Nasdaq more extended than the S&P 500, and the Dow calm — which points to rotation from growth toward value rather than a market-wide exit. Most importantly, the distribution-day count is a caution gauge, not a sell trigger; Gary Glover sees one more leg as possible into the seasonal window. The signals worth watching from here are whether the Nasdaq distribution count keeps rising and ranges keep expanding, whether value and old-economy names keep firming, and how the late-June-to-October midterm-year map plays out.

Frequently Asked Questions
What is the exact definition of a distribution day?
Under Investor's Business Daily's rule, a distribution day occurs when the Nasdaq Composite or S&P 500 closes down at least 0.2% on volume higher than the prior session. The volume does not need to be above average — only above the day before. It is the signature of institutional selling, drawn from the "M" (Market Direction) in William O'Neil's CAN SLIM methodology.
How many distribution days signal a market top?
There is no single trigger number, but a cluster is the warning. IBD's classic danger zone is four to five definite distribution days over four to five weeks, and more recent guidance is that markets often roll over after six or seven within 25 sessions — though some uptrends survive eight or more. Gary Glover noted roughly seven on the Nasdaq versus four on the S&P 500 to 30 June 2026.
When does a distribution day expire?
A distribution day stops counting after 25 trading sessions, or sooner if the index trades 5% above that day's closing price at any point. That makes the tally a rolling, self-clearing count over the most recent 25 sessions rather than a running total since the high — which is why several distribution days inside the same window matter more than the same number spread across months.
What is the difference between accumulation and distribution?
Accumulation is buying pressure — up days on heavier volume, as institutions build positions. Distribution is the reverse — down days on heavier volume, as institutions reduce. A market shifting from accumulation to distribution is shifting from strong hands adding to strong hands trimming. That change of character is what often precedes a top, even while prices are still near their highs.
Have distribution days warned before past market tops?
Yes. William O'Neil and IBD document distribution clustering before the March 2000 Nasdaq top (including churning at the 5,048 peak), the October 2007 top (five distribution days by 31 October, prompting IBD's "Market in correction" signal), and the September 2021 decline (a stalling day on 1 September that preceded the 8 September leg lower). In each case the evidence built before the deeper fall.
What is a stalling day?
A stalling day is a subtler form of distribution: the index closes higher or roughly flat on heavy volume, but makes little upward progress and finishes near the day's lows. The heavy volume without price gain shows supply meeting demand. IBD read the 1 September 2021 session this way before the Nasdaq's September decline.
Why is the Nasdaq showing more distribution than the S&P 500 or the Dow?
Because the selling is concentrated in growth. Gary Glover noted roughly seven Nasdaq distribution days versus four on the S&P 500 and effectively none on the Dow, which held near 52,000. When one index distributes while another stays calm, it points to rotation between sectors rather than a market-wide exit.
What happens to ASX stocks when US indices start to top out?
Often a rotation rather than a collapse. Gary Glover's anecdotal recall is that after the March 2000 Nasdaq peak, value shares rallied around 11% over the following year-plus while the Nasdaq fell. On the ASX that has tended to favour low-PE, higher-yielding names and beaten-down large caps — though the local index can also simply grind sideways, as it has through its recent range.
Does a high distribution-day count mean a trader should sell everything?
No. The IBD reading of past tops raised cash progressively as the count built, rather than picking an exact peak. Gary Glover's anecdotal observation is that distribution is a caution gauge — in the 30 June 2026 session he was explicit the high was not yet in. The disciplined read is to raise caution, lean on relative strength, and size down. Traders unsure how this applies to their circumstances may wish to speak with a qualified financial adviser.
