Why now
SEC filings are public. Knowing which one matters still isn't.
EDGAR is free, complete, and authoritative. The problem is turning 6,000 filings a day into the two or three that should actually change how you think about a position this week.
Important filings arrive all day
A Form 4 at 4:02pm or an 8-K mid-session can move a stock before you ever refresh EDGAR. Manual checking means you're always late.
8-Ks and exhibits hide the event
The headline is buried under boilerplate and attached as an exhibit. The thing that matters is one sentence on page nine.
Insider trades need context
A Form 4 is just codes and share counts. Is this a routine 10b5-1 sale or the CFO's first open-market buy in three years? The filing won't tell you.
Pro terminals are overkill
BamSEC and AlphaSense are powerful and priced for institutions. Most investors don't need another document reader — they need actionable alerts.
How it works
From 6,000 filings a day to the three that matter.
No dashboards to learn, no raw filings to parse. Point FilingRadar at the tickers you care about and it does the watching.
Build your watchlist
Add the tickers you hold or follow and the filing types you care about — Form 4, 8-K, 13D/G, 10-Q, S-1. No import, no onboarding call.
We watch every filing
A continuous pull of EDGAR — every Form 4, 13D/G, and 8-K for your tickers, straight from the source, nothing skipped.
AI scores the signal
Insider-buying clusters, 5%+ activist stakes, and surprise events get scored Strong, Notable, or FYI — grounded in the filing's real fields.
You get a plain-English alert
"CFO bought $2.1M — first open-market buy since 2021." What changed, why it matters, and a link to the raw filing.
The signals
Three kinds of filing reliably precede price moves.
Each one arrives with a plain-English summary, the numbers that matter, and a score — so you can act on the strong ones and skip the noise.
Insider clusters
Multiple insiders buying within days, or a single buy that's unusually large versus that person's history. The strongest tell in the book.
Activist stakes
The moment a fund crosses 5% and signals intent — board seats, a strategic review, or a push to sell. We flag the filer and the ask.
Material events
M&A, executive changes, guidance cuts, financings, and litigation — surprise corporate events the moment they're disclosed.
Real-time delivery
Email the instant a watched ticker files something that scores. A daily digest batches the routine; strong signals hit immediately.
Plain-English read
What happened, why it matters, and how big it is — grounded in the filing's real fields and always linked back to the source.
Per-ticker history
A clean, searchable timeline of every high-signal filing for any U.S.-listed company — insider trades, activist stakes, and 8-Ks in one view.
The plain-English read
Every alert answers what happened, why it matters, and how big — before you open the filing.
Raw filings are codes, exhibits, and boilerplate. FilingRadar reads each one and returns a structured, source-backed summary so you can make a call in seconds, not after an hour of EDGAR.
01What happened - a one-line, plain-English read on the filing.
02Why it matters - the investor's-eye view, with historical context.
03How big - the dollars, the percentage, the score, the link to source.
Strong — act-worthy
Notable — worth a look
FYI — context only

Form 4 · Insider clusterScore 85 / 100
Three NVDA insiders bought a combined $4.2M of stock in 5 days — including the CFO's first open-market purchase since 2021.
What happened
The CFO, a director, and an EVP filed Form 4s reporting open-market buys, not option exercises or planned 10b5-1 sales.

Why FilingRadar
Lightweight where EDGAR is passive, affordable where the terminals are heavy.
SEC EDGAR is authoritative but built for lookup, not action. BamSEC and AlphaSense are deep but priced for institutions. FilingRadar sits in the middle: alert-first, plain-English, self-serve, and cheap enough to just start.

FAQ
Built to surface filings, not to give you advice.
Is this investment advice?
No. FilingRadar provides informational, plain-English summaries of public SEC filings and links back to the original document. We don't give buy/sell ratings or recommendations — always verify against the source filing.
Where does the data come from?
Entirely from official SEC EDGAR sources — company submissions, the latest-filings feeds, and the raw filing documents. We're not affiliated with or endorsed by the SEC.
How fast are the alerts?
For watched tickers, a scored alert is typically sent within a minute of the filing appearing on EDGAR. Lower-priority matches are batched into a daily digest.
Which filings do you cover at launch?
The high-signal forms first: Form 4 (insider trades), SC 13D/G (activist and 5%+ stakes), and 8-K (material events). 10-K/10-Q diff summaries, S-1, and 13F follow close behind.
Can the AI be wrong?
It can miss nuance, so every summary is conservative, flagged for review when needed, and linked to the original filing. Treat it as a fast first read, not a substitute for the document.
