The fund is a passively managed fund that tracks an index of gold mining companies. The index has a simple premise: take the top 20 largest companies by market cap in the gold mining sector, and weight them equally within the portfolio. To be eligible for inclusion in the index, these companies must be listed on a regulated stock exchange in developed market countries. A constituent is dropped if they fall out of the top 25 companies according to company market capitalization, and will be replaced with the next largest company not already held by the fund. HGGG employs a sampling strategy, meaning it will try to hold securities in approximately the same proportion as that of the index. The index is rebalanced and reconstituted quarterly.
