AUMI vs SGDM

AUMIBThemes Gold Miners ETF

SGDMBSprott Gold 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.

SGDM SGDM doesn't just rank gold miners by size. It tracks a custom-factors index of roughly 50 larger miners listed in Canada and the US, and charges 0.46%, under its peer group's median fee.

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.

SGDM The fund seeks to track, before fees and expenses, the performance of the Solactive Gold Miners Custom Factors Index, which targets larger gold companies listed on Canadian and major U.S. exchanges.

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

• SGDM Fee of 0.46% sits under the median for precious-metals miner funds, and under both GDX (0.51%) and GDXJ (0.52%).
• Rules-based and named out loud: it follows the Solactive Gold Miners Custom Factors Index (SOLGMCFT), and it has stayed close to that stated mandate.
• Running since 2014, a long life for a thematic fund, and it holds about 50 larger gold companies rather than a sprawling list.
• Lands in the upper half of the gold and silver miner group in our review, with high confidence in the underlying data.

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.

• SGDM Thinly traded next to the category's giants, so spreads can be wider and larger orders can push the price around.
• The index sticks to Canadian and major US listings, so gold miners quoted only on other exchanges sit outside the portfolio.
• One industry, driven by the gold price and how well mines actually run, so the ride is bumpier than a broad stock fund.
