Stocks fall on good news because an announcement delivers the one thing a large shareholder waiting to exit has been short of: buyers. In a thinly traded company, a holder with a meaningful parcel has no way out on an ordinary day. News brings volume, volume is the exit, and the selling that follows can outweigh the buying the announcement attracts. The price falls while the news itself remains good. That mechanism was described by 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, speaking on 21 August 2026 from his own years executing those sell orders — one of which, he recalled, ran for 21 to 22 consecutive trading days.

Why Does a Smaller ASX Company Sometimes Fall on a Good Announcement?
Because an announcement solves a seller's problem before it solves a buyer's. A company trading a few thousand dollars a day offers no exit to a holder with a large parcel. Any attempt to sell into that market moves the price against them before the order is half filled. So the parcel waits — sometimes for years — for a day when enough buyers arrive at once. An announcement is that day.
The reason this reads as counterintuitive is that most traders treat a price reaction as a verdict on the news. It usually is, in a liquid company. In a thin one, the first thing good news buys is liquidity, and liquidity is what a seller has been waiting for. The resulting print describes the share register, not the announcement.
"That's why you often sort of see these small names sort of come off in the face of good news." — Gary Glover, 21 August 2026 session
Gary Glover's anecdotal observation, developed across his trading career, is that this is ordinary behaviour in the smaller end of the ASX rather than an anomaly. It sits alongside a related but distinct pattern at the index level, where a long-anticipated catalyst arrives and the buying that anticipated it has already happened — the dynamic Finer Market Points has covered separately in how a market catalyst can mark a top. The two look alike on a chart. They are not the same thing. One is a crowd that has already positioned; the other is a single holder who could not.
Who Is Selling Into the News, and Why Do They Have To?
How These Companies Are Put Together
The seller is typically a founding or seed shareholder in a company that was assembled around an asset. Gary described the structure plainly: a corporate vehicle is put together, a key asset and key people are brought into it, and the promoters take scrip at a low issue price — he suggested a couple of million shares at half a cent as an illustration — with further scrip issued over time as performance hurdles are met.
Two or three years later, those holders are sitting on a large parcel acquired at a fraction of the current price. The reasons they want to realise it are ordinary. Gary listed them without ceremony: a house, a boat, a tax bill. He was direct that, in all his years of broking, assembling a vehicle in this way and exiting it was among the more effective wealth-building approaches he had watched from the desk.
Why the Exit Takes Weeks
The parcel cannot be placed in a day, which is why the selling outlasts the announcement. Gary's own role for much of his career was executing those orders, and his recollection of the scale is the useful detail:
"They don't care where they get out. They just… need liquidity to get out." — Gary Glover, 21 August 2026 session
He recalled working one small name for 21 to 22 consecutive trading days, selling into every session. A trader watching that chart sees a stock that will not advance, on volume that looks healthy, for a month. Nothing in the announcement explains it, because the announcement is not what is happening.
This is lawful selling by shareholders entitled to sell, and it is disclosed. Nothing in the mechanism described here involves acting on information that is not already public — the entire point is that the seller is waiting for the market to have the news, because that is when the buyers arrive.
What Does the Disclosure Regime Actually Show a Trader?
A holder of 5% or more of the voting shares in a listed company is required under section 671B of the Corporations Act 2001 (Cth) to lodge a substantial holding notice within two business days, and to lodge again on any movement of at least 1%. This is one of the few places in the mechanism where a trader gets documentary evidence rather than inference.
What the regime makes visible is useful but partial:
A holder beginning or ceasing to be a substantial holder
Any movement of at least 1% in an existing substantial holding
The identity of the holder and the price range of the transactions
What it does not make visible matters more for the trader watching in real time. A holder sitting below the 5% threshold never appears at all. Neither does the pace of an order in progress — the notice arrives after the movement, not during it. The 1% rule is the part worth knowing, because a holder selling down from 6% leaves a paper trail before they have finished, which is occasionally enough warning to be useful.
The practical consequence is that the chart usually shows the selling before the paperwork does. That makes the next two sections a question of reading price and volume rather than reading the register.

How Is This Different From Overhead Supply?
Overhead supply is many small holders trying to get back to break-even; a working sell order is one large holder trying to get out at any price. The two produce a similar-looking chart and call for opposite responses, so telling them apart is worth the effort.
Gary described the overhead supply case during the same session, using Accent Group (ASX: AX1) as the example. The retail segment had been difficult, the stock had broken below its 50-day moving average, and it then reported a result the market liked and gapped higher — an episodic pivot in shape. The rally was capped anyway. His explanation was about the holders sitting above it: everyone who bought at each higher level is looking to sell into any decent rally, and the target is not a profit but a recovery. Some want half their money back, some want three-quarters, some want the price they paid. Finer Market Points has covered what overhead supply does to a rally in full separately.
Overhead supply | A large holder working an order | |
Who is selling | Many holders who bought higher | One holder with a single parcel |
What they want | To get back toward break-even | Out, at close to any price |
How it is distributed | Spread across price levels | Concentrated in time, not price |
How it ends | Thins gradually as each level clears | Stops abruptly when the parcel is placed |
What it asks of a trader | Patience — the levels do clear | Avoidance — until it ends |
Gary's related point is that at an all-time high neither problem exists. Every holder is in front, nobody needs to recover anything, and there is no supply waiting above the price to be worked through.
What Is the Vacuum, and How Does a Trader Spot the Seller Finishing?
The Vacuum
When a large order completes, the pressure that was capping the stock simply stops — and the absence is more consequential than the selling was. Christopher Hall framed it during the session as a vacuum:
"The vacuum that you or I create when we finished our sell order… the selling pressure is eased, and then anyone who wants to buy has to pay up. We're no longer feeding them." — Christopher Hall, 21 August 2026 session
While the order was live, every buyer was being served. Nobody had to bid up, because stock was always available at the offer. The moment that supply is exhausted, the next buyer has to reach higher, and the stock can move a long way on modest volume. The mechanism is the mirror image of the one that held it down.
What the Contraction Looks Like
The tell is a contraction in range and volume, not a price signal. A stock that has been fed all month suddenly trades a very narrow session on volume that has dried up, because the seller is no longer there and the buyers have not yet noticed.
Narrow range days have a documented literature. Toby Crabel, in Day Trading with Short Term Price Patterns & Opening Range Breakout (1990, now out of print), set out the NR4 and NR7 — a session whose high-to-low range is the narrowest of the last four or seven. The premise is that a volatility expansion often follows a volatility contraction, the same logic underlying the Bollinger Band Squeeze. David Weis in Trades About to Happen (2013) and Richard Wyckoff before him describe the same event in supply-and-demand terms: a narrow range on depleted volume means the supply that was being absorbed has run out.
Gary's caveat travels with the pattern and should not be dropped. He was blunt that these bars appear everywhere — a chart is littered with them, and traded in isolation they generate far more false signals than useful ones. They carry weight inside an existing tightening pattern: a B-wave, a volatility contraction pattern, a high tight flag. Finer Market Points has set out the NR7 entry and its risk definition separately, and a Wyckoff spring covers the washout version of the same exhaustion.
Gary's worked example was Energy One (ASX: EOL), a chart he called a basketball held under water — price pushed down through the session, bouncing hard off the low, closing back above the 10-day moving average, on an unloved chart following a good update. He named Mayne Pharma (ASX: MYX) as a second instance from the same reporting season. He also said he had been stopped out of it and was still watching, which is the honest version of what this tell is worth. It marks a condition, not an outcome.
One further constraint applies to the deeper cases. Gary's anecdotal observation is that after a V-shaped sell-off, roughly 97% of stocks need time to build a base — only about 2% or 3% recover in a V, and he named Afterpay as the rare exception he had seen. An impulsive move normally requires at least three months of congestion, and consolidations can run three, five, seven or nine months. The vacuum can lift a price; it does not shorten a base.
Why Is the 2026 Reporting Season Amplifying This?
The Reaction Window Has Halved
The market is repricing results roughly twice as fast as normal, which compresses both the seller's opportunity and the trader's. Gary's observation from the 21 August 2026 session was that a good result would normally rally for about three days and a poor one sell off for about three, and that in this reporting season the window has been cut to a day or a day and a half. Alongside it he described V-shaped and W-shaped turns and stocks darting up and then straight back down.
Company | What Gary observed | Time to reverse |
Super Retail Group (ASX: SUL) | A good result, one day of strength, then selling | About one day |
Seek (ASX: SEK) | Run up into a slightly disappointing result, buried, then a bounce on the second day and higher again the next | Two days down, then recovery |
Sonic Healthcare (ASX: SHL) | About 15% growth delivered, met by a downgrade of roughly 1% to FY27 and about 2% to net profit | Down about 10% |
CSL (ASX: CSL) | A result carrying a decent write-down, received as better than feared rather than good | Held, close to a 100% financial-year rally |
Gary's reading of Sonic is worth separating from the figures themselves: in the prior year the market had looked for about 13%, received 9% growth, and sold the stock down; this year it wanted less, got more, and still marked it down on a small trim to next year's outlook. His conclusion was that management restraint on guidance is the sensible posture in this environment. These are his session observations rather than figures drawn from the company's reports.
What the Data Says About the Conditions
The proprietary readings put the difficulty in context. Christopher Hall's Momentum Profile summary at the time of the session showed conditions better than only 32% of observations, with 63% of tradable ASX companies above their 50-day moving average, and the composite reading approximately 1% harder than normal to trade. Breadth was reasonable; longevity and follow-through were not.
Gary's response was to adjust rather than to stop. He noted that Mark Minervini keeps the same setup in a weak tape but tightens risk and accepts smaller gains, and said plainly that this is not a market in which to overstay a position — that he would take more off into a strong move than his rules would normally call for, and that a good trader has to do what the tape is telling them. Finer Market Points has covered the same adjustment as hard penny market trading conditions.
Conclusion
A fall on good news is usually a supply event rather than a verdict. In the smaller end of the ASX the seller is generally a large holder with an ordinary, lawful need for liquidity and no other day on which to get it — and the selling can outlast the announcement by weeks. The end of it is visible as a contraction in range and volume rather than as a price signal, and the vacuum that follows is where the move often comes from. What is worth watching from here is whether the compressed reaction window persists past the August 2026 reporting season, or whether results return to being repriced over three days rather than one.

Gary closed the session on a line he had read that morning from US momentum trader Dan Zanger, and it fits the mechanism described here better than most:
"Love your stops, not your stocks." — Dan Zanger, quoted by Gary Glover, 21 August 2026 session
A stock that will not advance on good news is telling a trader something about its share register, and the stop is the part of the position that does not require knowing what.

Frequently Asked Questions
Why Does a Stock Fall on Good News?
Because an announcement creates trading volume, and volume is what a large shareholder waiting to exit has been missing. In a thinly traded company the selling that arrives on good news can outweigh the buying it attracts, so the price falls while the news itself remains good. The move describes the share register rather than the announcement.
How Long Can a Large Shareholder Take to Sell Out of a Small ASX Company?
Longer than most traders expect. Gary Glover noted during the 21 August 2026 session that he had once worked a sell order for a major shareholder across 21 to 22 consecutive trading days. In a company that trades thinly, a single parcel can take weeks to place without collapsing the price, which is why a stock can stay capped long after the announcement that triggered the selling.
How Can a Trader Tell Whether a Large Shareholder Is Selling?
Rarely with certainty, and usually from the chart before the paperwork. Rallies are repeatedly capped near the same level, volume is heavy without net progress, and follow-through fails on days that should have produced it. A substantial holding notice confirms it afterwards, but only for holders above the 5% threshold.
Is Selling Into a Good Announcement Legal?
Yes, where the selling is based on public information and the holder meets their disclosure obligations. A holder with 5% or more of the voting shares in a listed company is required under section 671B of the Corporations Act 2001 to lodge a substantial holding notice, and to lodge again on any movement of at least 1%. This is general information and not legal advice.
What Is the Difference Between Overhead Supply and a Large Seller Working an Order?
Overhead supply is many holders spread across higher prices, each waiting to get closer to break-even, and it thins as the stock clears each level. A single large seller is concentrated in time rather than price and stops abruptly once the parcel is placed. The first situation calls for patience; the second calls for avoidance until it ends.
What Does It Look Like on a Chart When the Selling Finishes?
The range contracts and volume dries up. Narrow range days — the NR4 and NR7 bars described by Toby Crabel — mark a contraction in volatility that often precedes an expansion. Gary Glover cautioned during the 21 August 2026 session that these bars appear constantly and produce many false signals, and that they carry more weight inside an existing tightening pattern than they do on their own.
Should Traders Avoid Smaller ASX Companies Around Announcements?
Not necessarily, but position size is the adjustment that matters. Gary Glover observed during the 21 August 2026 session that smaller companies are hard to enter and exit, and that this is the same characteristic that lets a single seller dominate the price. Traders in this situation may wish to speak with a qualified financial adviser about position sizing appropriate to their circumstances.
