Weight bar: held both quarters added sold at this quarter’s reported price

* Reported price is value ÷ shares from the 13F as of period end, not a live market quote. Weight % is each long-equity position ÷ full 13F AUM, so rows may not sum to 100% when the filing includes options or other non-equity (excluded from this table). Share change and $ change are vs 2022 Q2. Click a column header to sort, or New, Hold, Add or Reduce to bring those moves to the top. Exit opens the last-held block below.
