How to read this filing
- Start with the largest positions and changes, then open issuer-level rows for CUSIP-specific history.
- Form 13F market value excludes cash and many non-13F assets, so it should not be treated as total assets under management.
- SEC classifies this as a combination report: some holdings appear here and some are reported by other listed managers.
