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 holdings report: this manager reports its visible U.S.-listed equity holdings in this filing.
