IONCProShares S&P Global Core Battery Metals ETF

REMXAVanEck Rare Earth and Strategic Metals ETF

In short

ION Most battery funds hand you carmakers and cell assemblers. ION stays upstream: only the miners pulling lithium, nickel and cobalt out of the ground, weighted by how much of their revenue actually comes from those three metals.

REMX The original rare earths ETF. Trading since 2010, it holds roughly 30 miners, refiners and recyclers of the metals behind magnets, EV motors and defense hardware, in one concentrated global basket priced under most of its critical-materials rivals.

Stated mandate

ION ION invests globally in companies producing battery metals used in next-generation technologies. Its mandate focuses on lithium, nickel, and cobalt mining companies and the battery-driven demand supporting those metals.

REMX The fund seeks global exposure to companies involved in producing, refining, and recycling rare earth and strategic metals and minerals, while tracking the MVIS Global Rare Earth/Strategic Metals Index before fees and expenses.

Why people hold it

  • ION Launched in 2022 as the first ETF built to hold only battery-metals miners. No EV brands or battery assemblers riding along in the basket.proshares.com
  • The index ranks companies by the share of revenue they earn producing cobalt, lithium and nickel, so the purest miners carry the heaviest weights.spglobal.com
  • A 0.58% expense ratio sits below the typical fee in the critical-materials aisle, and the fund distributes quarterly.proshares.com
  • Global net: the eligible pool is S&P's worldwide market index, so miners listed outside the US compete for slots on equal footing.spglobal.com
  • REMX Launched in 2010, it is the elder statesman of rare earth funds, and its mandate spans producers, refiners and recyclers worldwide rather than one link in the chain.
  • Fee of 0.53% a year undercuts Global X's EART (0.59%) and Sprott's SETM (0.65%), and sits below the median for its critical-materials peer group.
  • A multi-billion-dollar fund that trades actively, which matters in a corner of the market where the underlying stocks are thin.
  • Rules-based, not discretionary: the basket follows the MVIS Global Rare Earth/Strategic Metals Index, so holdings are set by published index rules.

Worth knowing

  • ION Roughly 50 miners levered to three commodity prices. Purity cuts both ways: when lithium, nickel and cobalt move, there is little else in here to cushion it.proshares.com
  • A small, thinly traded fund. Spreads can run wider than in the aisle's household names, which matters most on larger orders.
  • Broader miner funds such as PICK spread across metals and mining generally and charge less. ION is the narrower, more concentrated cut of the theme.
  • REMX About 30 holdings means one company's news can move the whole fund. This is a focused bet on a single supply chain, not a diversified materials sleeve.
  • Mining and refining shares move with commodity prices, so swings here run deeper and faster than in a broad equity fund.
  • Distributions arrive annually or semiannually, so cash flow is lumpy rather than a steady drip.

How we measure overlap

Each holding counts at its smaller weight in the two funds, summed over the full Holdings. Sector, country and asset class use the same rule on each fund’s split. Cash, FX and derivative lines stay out of the counts. Two bond funds get no overlap figure.
