How to read this. A Form 13F lists long positions in US-listed securities at
quarter-end. It is filed up to 45 days later and does not show short positions, most derivatives, non-US holdings, cash, or
trades made after the quarter ended, so it is a historical snapshot—not a current portfolio. Values are as reported in the
filing. This page is not investment advice and does not suggest buying or selling any security.
