AUMIBThemes Gold Miners ETF

SILJCAmplify Junior 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.

SILJ The original junior-silver play. Since 2012 SILJ has done one job: passively track an index of roughly 70 small silver miners, producers and explorers, the high-octane end of a niche most metals funds cover with gold.

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.

SILJ The Fund is a passively managed ETF seeking results that generally correspond, before fees and expenses, to an index focused on companies engaged in 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
  • SILJ Pure junior-silver mandate: the index holds companies that earn most of their revenue from silver mining, production or exploration, not a gold fund with a silver garnish.amplifyetfs.com
  • A multi-billion-dollar fund that trades actively, which matters in a corner of the market built from thin, tiny stocks.
  • Rules over hunches: a passive fund that rebalances when its Nasdaq index does, with roughly 70 holdings and a published methodology behind them.amplifyetfs.com
  • Launched in 2012, it has run through several silver cycles and kept the same strategy through a change of sponsor to Amplify and an index renaming in 2024.sec.gov

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.
  • SILJ The 0.69% expense ratio sits above the typical fee in its precious-metals-miner peer group. Specialist access has a sticker price.
  • Non-diversified by design and concentrated in metals and mining, so a handful of names can drive the outcome.amplifyetfs.com
  • Junior miners are the geared end of silver. The prospectus flags small-cap, foreign-issuer and commodity-price risks that move the fund in both directions.amplifyetfs.com
