What its reported holdings returned
Held through each quarter, the holdings it reported returned -12.9% over the 2 quarters to 30 June 2026, against +9.5% for the S&P 500.
Not the fund's own return: each 13F's holdings are kept unchanged until the next one, so trades inside a quarter, dividends, cash and fees are left out. A rough guide to how its picks have done over time.
