AUMI vs SIL

AUMIBThemes Gold Miners ETF

SILCGlobal X Silver Miners ETF

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.

SIL The original US silver-miner ETF, listed since 2010 and still the big, liquid name in a small aisle: about 40 global companies that mine, refine and explore for silver, rather than the metal in a vault.

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.

SIL The fund seeks to track the performance of the Solactive Global Silver Miners Total Return Index before fees and expenses, focusing on companies economically tied to silver mining.

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

• SIL The genre's originator, trading since 2010, now a multi-billion-dollar fund that changes hands actively, so getting in and out rarely takes gymnastics.globalxetfs.com
• Miners, not metal: roughly 40 global companies engaged in silver mining, refining or exploration, so production and cost discipline matter alongside the silver price.globalxetfs.com
• Rules-based and readable: it tracks the Solactive Global Silver Miners Total Return Index, so the lineup follows published index rules, not a manager's hunches.globalxetfs.com

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.

• SIL It charges 0.65% a year, above the typical precious-metals miner fund. Newer rivals undercut it: SLVP at 0.39% and AGMI at 0.35%.
• A global book, much of it listed outside the US, so currency swings and country-level mining rules ride along with the silver story.globalxetfs.com
• Income is a side effect here: cash distributions land once or twice a year, not monthly.
