A small cap scanner with SEC filings tracks price and volume on small caps and tells you, in the same alert, which EDGAR filing sits behind the move: a 424B prospectus, an S-3 shelf, an 8-K, a Form 4 insider buy, or nothing at all. Judge one on five things: speed from EDGAR to you, forms covered, honest plain-English summaries, delivery and cost.
Hypothetical example: a ticker rips 80% before lunch. A price-only scanner tells you it is moving. A filings-aware scanner tells you a 424B5 landed on EDGAR an hour ago, or that there is no new filing at all. Those are two very different situations, and that second piece of information is the part worth paying for.

What is a small cap scanner with SEC filings integration?
It is a scanner that joins two data streams, live market data and the SEC’s EDGAR filing system, so a price alert arrives with its paperwork attached.
A regular scanner filters on price, percent change, volume, relative volume and sometimes float. A filings-aware one also watches EDGAR, matches each new filing to a ticker and labels it: offering, shelf registration, current report, insider transaction. Better ones go further and track how much a company can still issue, from remaining shelf capacity to outstanding warrants, convertibles and at-the-market programs.
That last part matters more than the headline alert. A company with an effective shelf and a pile of cheap warrants has supply waiting above the price, even on a day with no new filing.
How do scanners pull EDGAR filings in real time?
EDGAR publishes filings after the SEC accepts them. Scanners typically poll the latest-filings feeds or the SEC’s EDGAR APIs, map the filer’s CIK number to a ticker, read the form type and parse the text. The SEC’s fair access rules limit how fast automated tools can request data, so vendors have to be efficient about it.
Every step adds delay: SEC acceptance, the vendor’s polling interval, parsing, summarising, then delivery to your phone or Discord. When a vendor says real time, ask which of those steps they are actually measuring.
Why does a move with a 424B read differently from a move with no filing?
Because a 424B usually means stock has been priced or registered for sale, so there is new supply at a known price, while a move with no filing has no disclosed seller behind it yet.
A 424B is a final prospectus or prospectus supplement filed under Rule 424(b). On small caps, a 424B5 or 424B4 often accompanies a priced offering: the company sold shares, the price is fixed, and those shares can hit the tape. Not every 424B is a fresh raise (many 424B3 filings cover resales by existing holders), which is why the scanner should tell you which kind it is. Our guide to reading a 424B5 prospectus supplement walks through the sections that matter.
Fockets Terminal data shows why the label matters: runs on a priced offering closed down 4.3% on average and 65% of them faded, while runs on an 8-K closed up 3.5%. That is an average across many runs, not a prediction for the next one. But it tells you the same green candle carries different odds depending on the paperwork behind it.
A move with nothing behind it is not automatically clean. It can be news that has not been filed yet, sector sympathy, a low-float squeeze or plain promotion. It can also be a company sitting on an effective shelf it has not used yet. No filing just changes the question from who is selling at a fixed price to why is this moving, and who could sell into it.
A biotech running up ahead of a scheduled FDA decision can show no new filing at all, so use our guide to what to check in the filings during a PDUFA date run-up.
| What sits behind the move | What it usually means | What to check next |
|---|---|---|
| 424B4 / 424B5 | Priced offering or shelf takedown | Offering price, share count, warrants, closing date |
| S-1, S-3, F-1, F-3 | Registration or shelf: capacity to sell later | Size, and whether an EFFECT notice has posted |
| 8-K / 6-K | Material event: deal, results, financing | Which item number; Item 3.02 means unregistered share sales |
| Form 4 (code P) | An insider bought on the open market | Size relative to their holdings, price paid |
| Nothing new | Undisclosed catalyst, momentum or promotion | Existing shelf, warrants, ATM, recent press releases |
What should a small cap scanner with SEC filings have? The buyer’s checklist
Check seven things before you pay: latency, forms covered, summary quality, dilution tracking, delivery, coverage and price.
| Criterion | Question to ask | Red flag |
|---|---|---|
| Latency | How many seconds from EDGAR acceptance to my alert? | Real time claims with no timestamps you can check |
| Forms covered | Does it read 424B, S-1/S-3/F-forms, EFFECT, 8-K items, 6-K, Form 4, 13D/13G, 144, S-8? | Only 8-Ks and press releases |
| Plain-English summaries | Does every summary link to the source filing? | No link, or numbers you cannot find in the filing |
| Dilution capacity | Does it show remaining shelf, warrants, convertibles and ATM size? | Float only, no overhang |
| Delivery | App, email, Discord, push? Can I filter what reaches me? | One firehose you will mute within a week |
| Coverage | How many US tickers, how often rescanned, any Canadian coverage? | Vague thousands of stocks with no refresh rate |
| Price | What is included at each tier, and can I test it before committing? | Return screenshots, calls, alerts to copy |
How accurate and fast are SEC filing alerts?
Test it yourself. Every EDGAR filing index page shows an acceptance timestamp. Pick a handful of 424Bs and 8-Ks over a week, note that time, and compare it to when the alert reached you. Do it premarket and mid-session, because load differs.
Accuracy works the same way. Open the source filing and check the share count, offering price and warrant terms against the summary. If they do not match, you have learned more about the tool than any review will tell you.
If the scanner writes its own summaries, our guide on what to verify before trusting an AI filing summary walks through the checks in more detail.
Which forms actually matter for small caps?
- 424B4, 424B5: priced offerings and shelf takedowns.
- S-1, S-3, F-1, F-3: registrations and shelves, the capacity to sell later.
- EFFECT: the SEC notice that a registration is effective and the shares can be sold.
- 8-K and 6-K: material events; foreign private issuers often report offerings on a 6-K.
- Form 4: insider transactions; code P is an open-market purchase, grants are not buys.
- Schedule 13D / 13G: 5% holders arriving, adding or leaving.
- Form 144 and S-8: insider sale notices and employee share registrations.
Plain-English summaries and delivery
Summaries save time, but a summary is only as good as the filing it reads. Good tools put the source link next to every line so you can check the numbers yourself. Treat any summary, human or AI, as a pointer to the filing, not a replacement for it.
On delivery, pick what you will actually watch. If you already live in Discord during the session, DM alerts beat an app you have to remember to open. Email is fine for overnight filings and useless for a 9:41 a.m. spike.
Are there free small cap scanners with SEC filings?
Partly: EDGAR itself is free and you can wire its feeds into alerts, but free tools rarely tie a filing to a live price move for you.
EDGAR full-text search lets you search filing text for phrases like warrants or at the market offering. The latest-filings page and RSS feeds show new filings as they post. Free stock screeners handle price, volume and float filters, though free tiers often run on delayed data. If you are willing to spend an evening, you can set up free SEC filing alerts to Discord straight from EDGAR feeds.
Some traders build their own version in Excel or a short script using the SEC’s JSON APIs. That works well for research, like pulling a company’s full filing history. For intraday speed it is weaker, because of request limits and parsing. The real cost of free is your time, and the matching step, which filing explains which move, is still on you.
Are paid small cap scanners a scam?
Most are not; they sell data and speed. What turns a tool into a problem is the pitch wrapped around it.
Be wary of any scanner sold with return screenshots, calls or alerts you are supposed to copy. A scanner is a research tool. It tells you what moved and what was filed. Deciding whether there is a trade, and how much to risk, is your job.

Where the Fockets Terminal fits
It is one option, built for the specific job of explaining moves with filings. Here is what it does:
- Ties big moves to the filing behind them: offering, 8-K, insider buy, or nothing.
- Translates filings into plain English.
- Shows how many more shares a company may issue.
- Rescans roughly 13,000 US stocks every 30 seconds.
- Sends price level, big move, unusual volume and opening-range break alerts to your Discord DMs.
- Includes the tape (time and sales), Congress trades and a trade log.
Full access includes the Terminal; the Fockets Terminal page lays out what you get. Run the checklist above on it exactly as you would on any other tool. It scans US stocks; for TSXV and CSE names, filings live on SEDAR+ and you will be checking those yourself.
FAQ
Is DilutionTracker legit and accurate?
It is an established dilution-tracking service. As with any tool that reads filings, ours included, treat its numbers as a starting point and spot-check them against the EDGAR source, especially warrant terms and share counts after a reverse split.
What is the best small cap scanner for beginners?
The one whose alerts you will actually verify. Beginners get more from a scanner that links every alert to its filing than from one with 200 filters. Start with a few alerts, read the filing on each, and keep notes on what happened next.
Do SEC filing alerts work for Canadian small caps?
Only for companies that also file with the SEC. Most TSXV and CSE issuers file on SEDAR+, and many financings show up first as press releases, so you need a separate process for those.
Can a scanner tell me whether to buy?
No. It tells you what moved and what paperwork is behind it. The read, the plan and the position size are yours, and that is the skill worth building.
