HGER attempts to diversify efficiently across commodities to target the most sensitive to US-CPI. Selection begins with the 24 most liquid commodity futures, scored for economic significance and quality, considering open interest, holding and trading costs, and inflation sensitivity. The index holds at least 15 commodity futures with weights ranging 2-20%, except gold which can have up to 40% weight. A proprietary scarcity debasement indicator determines the type of inflationary environment, to which the allocation to gold is adjusted accordingly. The index is reconstituted and rebalanced quarterly. Index calculation is based on total return, which includes the futures returns plus returns from managing the funds cash collateral. The fund invests using excess return swaps through a wholly owned Cayman Islands subsidiary, avoiding K-1 tax forms. Before March 6, 2023, the fund traded as the Harbor All-Weather Inflation Focus ETF and tracked the Harbor Inflation Index.
