The last ASX trading day’s announcements, ranked by what the market did about them
Catalyst Ahead reads every ASX filing as it lands. These are the day’s biggest price moves with real money behind them — one board for the drill bit, one for the clinic.
No company cleared the A$250k turnover floor this week — a quiet market, not a fault.
· ASX MOVERS
ASX risers and fallers — and the moves with no news behind them
The biggest price moves in mining and healthcare over the week and the month, with the volume behind them — and the companies that moved hard with no announcement lodged. Updated after each ASX close.
Open any company for its news-flow record — every market-sensitive announcement it has filed this year, against its price. Or press Chart on a row for its price chart, delayed 15 minutes.
Measured across 953 ASX mining and healthcare companies; 773 had a price at this close.
ASX movers, week and month →The same boards on a page of their own, with what counts as a mover, why the window is a week rather than a day, and what “moved with no news” does and does not mean.
· ASX MARKET CAP
Biggest ASX market cap gains and falls, in dollars
These boards rank by the dollars that moved, not the percentage — over the week, the month, the quarter and the year.

* 23% of the figures here are measured against a dated share count from the start of their window; the rest (marked *) are measured on today’s count. We started recording each company’s share count every trading day on 17 August 2026, so the record is still building out — the quarterly board is covered from about November 2026 and the yearly from about August 2027.
Measured across 953 ASX mining and healthcare companies; 770 had a share count at this close.

Catalyst Ahead is built and managed by stock pickers who kept meeting the same question — “when is that catalyst due?”. The platform’s AI reads each company’s own announcements, pulls out the source quotes that answer it, and settles them on a dated timeline — so you can see what is coming, and when, for every stock you hold.

Your holdings, and what is coming for them · The loop the whole product is built around: add the companies you hold, and get back a dated list of what each of them has said is coming.
Watchlist & catalyst timelineFlagshipFree with an account
Every catalyst you are waiting on, dated.
One line per holding
12-month catalyst timeline
Every date keeps its source quote
One line per holding — the next catalyst due, its date, how confident we are in that date, plus short interest, recent raises and cash runway on the same row. Underneath, a rolling timeline plots every expected announcement out to a year, colour-graded by confidence.
How it works When you add a ticker we read that company’s own ASX announcements and pull out the sentences where it says when something is due — “assays expected in the June quarter”, “FDA decision by year end” — and settle each one on a date. Every catalyst keeps the quote it came from, so you can check it against the source rather than take our word for it.
A free account holds a limited number of companies; the cap is stated on the page and on the pricing page, and it is the same cap the home page quotes.

The catalysts hiding in the interviews.
Conference talks + company videos
Catalysts timestamped to the moment
Watchlist YouTube scan is Pro
Mining-conference presentations and company videos, with the catalysts mentioned inside them pulled out and timestamped, so you can jump to the exact moment a claim was made, confirm it, and drop it onto your own timeline.
How it works The talk’s transcript is read for forward-looking statements the same way an announcement is, and every proposal it produces carries the timestamp it was said at. Nothing reaches your timeline until you have watched the moment and pressed confirm.
Browsing the conference library is free. Scanning your own watchlist for new company videos is a paid feature, and a free account gets a limited number of talks parsed.

Trading journalFree — no account needed
Your trading, honestly recorded.
Typed by you, computed in your browser
Day, week and month views
No broker connection
A day, week and month record of your own trading: entries and exits, size and direction, a running P&L, the behaviour and emotion you tag each session with, and a self-rating you fill in at the close. The week and month views are read-only retrospectives built from it.
How it works Everything on it is typed by you and computed in your browser — the equity curve, the aggregates and the pattern notes are all arithmetic on your own entries. We do not read your broker and we do not infer your trades from anything.
Without an account a session is saved in your browser only, so it will not follow you to another device.
What the whole market is doing · The public desks. None of these need an account, and they are the same pages the leaderboards at the top of this page link into.
News flowFree — no account needed
Market-sensitive news, ranked and deduped.
1,100+ ASX tickers
Market-sensitive only, deduped
Refreshed daily
Every market-sensitive ASX announcement, ranked and de-duplicated: a leaderboard of who is filing the most, a chronological stream, a breakdown by category, and a matrix crossing every category against every sector.
How it works We read the ASX announcements feed daily and count only the ones flagged market-sensitive, collapsing the repeats a single event generates so one piece of news counts once. The counts are stored as a single daily document, which is why the page loads instantly and costs nothing to serve.

Who really got bigger — in dollars.
Dollars, not percentages
Week, month, quarter and year
Price vs new shares, split
Who gained and lost the most market capitalisation over a week, a month, a quarter and a year — in dollars, not percentages, so a large company moving quietly outranks a small one moving loudly.
How it works Closing price multiplied by shares on issue, compared with the same figure at the start of the window. Where we have both share counts, the row splits the move into how much came from the price and how much from new shares being issued — a company can “gain a billion” purely by issuing stock, and the board says which it was.
Rows where we only hold today’s share register are marked as such and claim less. The board never presents an estimate as a measurement.

Reporting calendarsFree — no account needed
Every reporting window, one chart.
Statutory reporting windows
Twelve months on one chart
A calendar, not a prediction
The statutory reporting windows for the year, drawn as a twelve-month chart: quarterly activity and cashflow reports, half-year and full-year results, for the ASX and the other exchanges we cover.
How it works Straight from each exchange’s published filing deadlines. It is a fixed calendar, not a prediction — it tells you the window a company must report inside, not the day it will.
The mining desks · Two different questions about a miner — is it hitting guidance, and is the weather about to interrupt it.
Beta · company names hidden
Mining guidanceBetaPro
On track to hit guidance — or quietly behind?
Quarterlies vs stated guidance
Margins at any price you type
Identities hidden in beta
Producers tracked against their own stated guidance: quarterly production against the full-year target, so you can see who is on pace, who is ahead and who has to have an unusually strong quarter to get there — plus a cost-and-margin read you can run at any commodity price you choose.
How it works Production and cost figures are read out of quarterly reports, then compared with the guidance range the company itself published. The margin lens re-prices the same production at whatever spot price you type in, so you can ask what a fall in the metal would do.
Company identities are deliberately hidden on this page while it is in beta and we keep improving the accuracy of the figures behind it.
The mining desks · Two different questions about a miner — is it hitting guidance, and is the weather about to interrupt it.
Production weatherPro
Rain on a mine you hold? You’ll know first.
350+ operational mines
Open-Meteo forecasts + BoM warnings
30-year rainfall baseline
Operational mines plotted against live rainfall: which are wetter or drier than normal right now, filterable by commodity and state, and clickable through to the companies exposed to each site.
How it works Each mine’s location is matched to a live forecast and compared against a thirty-year rainfall baseline for that spot, so “wet” means wet for that place at that time of year rather than wet in the abstract. Updated daily.
The biotech desks · For holders of clinical-stage companies, where the catalyst is a trial result or a regulator’s decision rather than a quarterly.
Clinical trialsPro
The whole pipeline, phase by phase.
Phase-by-phase matrix
FDA, TGA and EMA designations
Advances only on filings
The pipeline of every ASX biotech we cover as a phase-by-phase matrix — what stage each programme is at, which indication it is in, and which regulatory designations it carries from the FDA, the TGA and the EMA.
How it works Trial records are reconciled against the companies’ own filings, so a phase only advances when an announcement says it has. Each row keeps the announcements behind it.

Readouts and decisions, by month.
Colour-coded by phase
Every date names its source
Estimates never dressed as fixtures
Trial readouts and regulatory decision dates laid out by month, colour-coded by phase.
How it works Dates are ranked by how reliable their source is: a sponsor-disclosed completion date beats a regulator’s decision date, which beats our own reading of a company’s guidance. Every entry shows which of the three it came from, so an estimate is never mistaken for a fixture.

IndicationsNo screenshot yet — the description below is the tour.
IndicationsPro
Everyone chasing the same disease.
Grouped by disease, not company
Ordered by progress
Deliberately beyond your watchlist
The same trials regrouped by disease rather than by company — everyone chasing the same indication in one table, ordered by how far along they are.
How it works Deliberately not scoped to your watchlist: the point is to show the companies you do not hold that are ahead of the one you do.
Who is raising, and who is short · The two things most likely to move a small-cap that have nothing to do with its project.
Capital raisesPro
Every raise, graded A–F.
Graded A–F
Two-year window
Dilution, discount, spend, price path
Placements, share purchase plans, equity lines and rights issues across a two-year window, each graded A–F, with the price path after the raise plotted so you can see whether the discount closed or stuck.
How it works The grade is built from four measurable things — how much the raise diluted holders, how deep the discount was, how specifically the company said it would spend the money, and how the price actually traded afterwards. A cash-runway read on top flags who is likely to have to raise next.
This page does not scan your whole watchlist on its own. You ask for a company and it answers — a deliberate choice, so it never runs up work you did not request.

From the regulator’s own reporting
Refreshed daily
Lagged by law — dated as at
Every ASX company carrying a reported short position, bucketed by how heavy it is, with the day-on-day change and your own holdings marked.
How it works From the regulator’s own aggregated short-position reporting, refreshed daily. It is reported on a lag by law, so the figure is a few days behind the market by design — the page shows the date it is as at rather than implying it is live.
