AUMI vs GDMN

AUMIBThemes Gold Miners ETF

GDMNCWisdomTree Efficient Gold Plus Gold Miners Strategy Fund

In short

AUMI Gold miners with the blends stripped out. AUMI tracks an index of roughly 30 large miners that must earn at least 90% of revenue from gold, and it charges less than the typical fund in its group.

GDMN Gold or the miners? GDMN declines to choose. For every $100 it aims to hold roughly $90 of global gold miners plus gold futures worth about $90 more in notional terms, stacking two gold trades into one ticker.

Stated mandate

AUMI The Fund seeks to track, before fees and expenses, an index of companies active in the gold mining industry. It uses a passive/indexing approach to pursue that objective.

GDMN The Fund seeks total return by investing in U.S.-listed gold futures contracts and global equity securities of companies deriving at least 50% of their revenue from gold mining. Gold futures are used to enhance capital efficiency.

Why people hold it

• AUMI The "pure" in the index name is a rule: members must generate at least 90% of revenue from gold mining, so copper-and-gold conglomerates and diversified diggers stay out.solactive.comthemesetfs.com
• A 0.35% fee undercuts the peer-group median and the category's household names, VanEck's GDX (0.51%) and iShares' RING (0.39%).
• Roughly 30 names, free-float weighted, rebuilt on a set schedule: a concentrated, rules-based way to own the diggers rather than the metal.solactive.com

• GDMN Return stacking in an ETF wrapper: about 90% of net assets in gold miner equities, with U.S.-listed gold futures adding roughly 90% of notional exposure on top.sec.govwisdomtree.com
• The 0.45% fee sits under the typical precious-metals miner fund and below GDX's 0.51%, even with the futures sleeve doing extra work.
• Discipline is written into the design: when exposure drifts 5% or more from the 90/90 target, the fund is expected to rebalance back toward it.sec.gov
• Actively run, but measured against the NYSE Arca Gold Miners Index, the same benchmark behind AUAU, so the equity sleeve is judged on familiar ground.

Worth knowing

• AUMI Thinly traded and small next to the group's giants, so bid-ask spreads can be wider and big orders can push the price.
• Concentrated by design and non-diversified: about 30 miners, one commodity, plus mine-level risks like costs, permits and politics.themesetfs.com
• Launched in December 2023, so the live track record is short, and cash comes back once or twice a year rather than monthly.

• GDMN The stack cuts both ways. Roughly 180% gold-linked exposure magnifies losses as well as gains, and the prospectus flags higher volatility than an unlevered version.sec.govwisdomtree.com
• It trades lightly next to the category's heavyweights, which can mean wider spreads and more care needed on size.
• Gold exposure runs through a wholly-owned Cayman subsidiary, routine for commodity futures in a fund but more machinery than a plain miners basket.sec.gov
