Schedule 13D and 13G activist stake filings by ticker: every beneficial-ownership filing made about a US-listed issuer in the last 365 days, each validated against its own cover page so a company's outbound filings about OTHER companies are excluded. Returns 13D vs 13G counts, amendments, reporting-person names and EDGAR links. 13D is the schedule filed without a passive/qualified certification. Public-domain SEC EDGAR. $0.005 per call.

"plain": "Schedule 13D and Schedule 13G are different filings. A 13G is the short form, available only to filers who certify they are a qualified institution, exempt, or passive. A 13D is the general schedule, filed by holders who do NOT make that certification — which is why a 13D is the one worth reading closely. That is the whole of what the form type tells you: it is not a declaration of activism, and it says nothing about the size or direction of the stake."

Otto AI · Equity News
x402.ottoai.services
Latest company news for a vendor-resolved equity: licensed Finnhub headlines from the trailing seven days with publication time, source, and summary. Only articles that name the company are served — labelled `primary` when the headline names it, `mentioned` when only the summary does — so a symbol-tagged story about another company never fills the list. Redirect URLs withheld; no sentiment is fabricated.
