Dilution risk scoring (0-100 Dilution Pressure Score with 5-dimension assessment)
SEC filing extractions (warrants, convertibles, shelf registrations, and 10 more types)
Instrument lifecycle tracking (warrants, convertibles, ATMs with XBRL reconciliation)
Intelligence (counterparties, counsel, insiders, institutions, ROFR triggers, cluster buys)
Cross-company intelligence (top AUM institutions, cross-company counsel & insider patterns)
Compliance monitoring (Nasdaq/NYSE deficiency detection, listing classification)
Company screening (dilution-aware filters with 30+ fields)
ETF analysis (holdings, sectors, countries, performance, comparables)
