SEC 13D/G Activist Stake Monitor: Investor Stakes and Intent Signals

See who is taking a big stake in a company - and whether they mean to shake it up. Provide one or more tickers and get their recent Schedule 13D and 13G filings from SEC EDGAR, classified and scored: activist (13D, intent to influence) vs passive (13G), new stake vs amendment, with the filer and a direct link. A curated stake signal, not a raw filing dump.

What it does

Activist vs passive: Schedule 13D (intent to influence) scored far above a passive 13G index holding.
Direction: inbound (someone is taking a stake IN this company) vs outbound (this company is taking a stake in another).
Filer identification: the actual holder/activist pulled from the filing header.
New vs amendment, plus an impact score 0-100 driven by filing type and recency.
A direct SEC.gov link for every filing.

Who uses activist-stake data

Traders and quants building event-driven and activist-campaign screens.
Fintech and research apps embedding 13D/G stake signals.
Competitive-intelligence teams tracking who is accumulating a position.

How it works

The tool reads the official SEC EDGAR submissions API (free, public, JSON), maps each ticker to its CIK, filters the 13D/13G filings, then reads each filing header to identify the holder and classify activist vs passive, new vs amendment. Clean and stable.

Example

GME in live data: GameStop itself disclosed a new Schedule 13D activist stake in eBay (outbound, impact 88), while RC Ventures / Ryan Cohen appear as inbound 13D/A amendments on GameStop.

FAQ

What is a Schedule 13D vs 13G? A 13D is filed by a >5% holder who intends to influence the company (activist); a 13G is a passive >5% holder. The “/A” suffix is an amendment. Which companies can I track? Any US-listed company with a ticker in SEC EDGAR, or any CIK. Is this investment advice? No. It is data for research and monitoring.
