Each list shows up to 20 positions, largest first by dollar amount. Changes compare two quarter-end snapshots, with the earlier share count adjusted for stock splits AltMountain detected. They do not show when, or at what price, anything was bought or sold.
From public Form 13F filings, not verified. Form 13F is filed up to 45 days after the quarter ends, so positions may have changed. It lists only certain long positions in U.S.-listed stocks and exchange-traded funds; options are not shown here, and short positions, most bonds, cash, non-U.S. securities and private investments are not reported at all, so a holding may be one side of a hedge. A filing covers the manager as a whole, not any single fund, and filings contain errors. This is not investment advice or a recommendation to buy or sell any security. Disclosures
