Factors Affecting Performance [Text Block]
WHAT FACTORS INFLUENCED PERFORMANCE FOR THE PERIOD?
Several factors contributed positively to the Fund’s performance during the period:
•Net long exposure to U.S. and developed market stocks, which did well this year.
•High exposure to Japanese stocks, which did well this year. Japan was the biggest country weighting in the ETF. Japanese stocks were (and still are) trading at much lower valuations than comparable U.S. stocks. The gap has been closing over the past few years due to corporate governance reforms that encourage companies to return cash to shareholders and divest crossholdings, among other things.
•Exposure to AI beneficiaries (both direct and indirect), which were one of the year’s best performing themes.
•Short exposure to publicly traded private credit via BDCs.
The biggest absolute detractors to the Fund were its large short positions in various higher-yield ETFs, which are used to hedge some of the Fund’s market exposure. However, the risk-adjusted returns of these hedges were generally worse than the risk-adjusted returns of the long positions.
