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.
