Methodology
Holdings come from the manager’s Form 13F-HR filings on SEC EDGAR, with amendments applied. Values and shares are reported at quarter-end; the filing date is when the report became public. These disclosures show reported long positions and listed options, not the manager’s entire portfolio or its trades since quarter-end.
Quarterly changes compare shares with the immediately preceding quarter on file. New and exited positions appear or disappear; added and trimmed positions change their share count by more than 1%. A share change can also reflect a stock split or other corporate action.
Opened and sold out is the value of new positions plus the prior value of exited positions, divided by the average of the two quarters’ reported portfolio values. It excludes changes to positions still held. Reported value growth includes price changes and is not a measure of investment performance. Largest-five and largest-ten weights exclude options.
