GDXJ's holdings include many smaller gold explorers and miners listed in Australia, Canada, the US and China.
RBC Capital Markets said in a note on the topic last week that the VanEckGDXJ ETF (assets under management) had expanded by 225% since 2016 to the point where it announced the inclusion methodology change.
"This has resulted in VanEck taking increasingly larger ownership stakes in relatively illiquid junior companies, which appears to have necessitated the change," RBC said.
Sameer Samana, a Wells Fargo Investment Institute quantitative strategist in St Louis, told Bloomberg: "They're starting to run into issues of how much they own in certain names, how many names qualify for the index and they're running into issues of how big the fund has gotten."
"The index provider is loosening the criteria and making it more inclusive in order to deal with the liquidity and capacity issues." ETF.com said GDXJ "may have become too big for its index, the MVIS Global Junior Gold Miners Index".
"The [now] $5.4 billion exchange-traded fund owns giant positions in its underlying holdings, putting it at risk of violating certain Canadian and US regulatory thresholds," it said.
"To avoid crossing those thresholds, the ETF bought up stocks of companies that aren't in its index — creating a significant divergence between the ETF components and the index components. VanEck acknowledged the divergence by announcing it would broaden the scope of the index and include many more gold miner stocks in the portfolio at the next rebalance date."
