AUMI vs SGDJ

AUMIBThemes Gold Miners ETF

SGDJBSprott Junior 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.

SGDJ Junior gold, filtered. Sprott runs roughly 30 explorers, developers and producers through a revenue-growth and price-momentum screen instead of owning the entire junior bench by size alone.

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.

SGDJ The Fund seeks to track, before fees and expenses, the performance of the Solactive Junior Gold Miners Custom Factor Index. It uses passive indexing and invests primarily in junior gold companies, including exploration-stage companies, developers and producers.

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

• SGDJ The screen is the whole point: the index tilts toward junior miners with better revenue growth and price momentum, not just whatever is small and listed.
• 0.50% a year, a shade under the median for precious-metals miner funds and under GDXJ's 0.52% for the broader junior basket.
• Trading since 2015 from a house built around precious metals, and it sits in the upper half of its miner peer group on our review.
• Rules-based and passive: it follows a published Solactive index rather than a manager's stock picks, so you can see what the portfolio is chasing.

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.

• SGDJ Juniors are the jumpy end of an already jumpy sector. Exploration-stage names move on drill results and financing, not only on the gold price.
• About 30 holdings, spread across US, developed, emerging and frontier listings. Concentration means one company's news lands harder than in a broad miner index.
• Moderately traded rather than a top-of-book name, so spreads deserve a look and limit orders earn their keep.
