About This Data

Schedule 13D/13G filings are SEC disclosures that report beneficial ownership. They are required when an investor acquires more than 5% of a company's shares. Schedule 13D filings indicate activist intent (potential influence over company direction), while 13G filings indicate passive investment.

New positions are filings where a fund discloses more than 5% ownership in a company for the first time.

We track 18 biotech-focused institutional investors with known sector expertise.
