Hypothetical clone — not this fund's returns. The performance on this page replicates only the long U.S. equity positions disclosed on this manager's Form 13F filings, rebalanced on filing dates at disclosed weights with dividend-adjusted prices. It excludes shorts, bonds, cash, non-U.S. listings, private holdings, leverage and fees. Treat it as a measure of how the disclosed stock picks performed, never as the fund's track record.
