Global investment manager VanEck has conducted a re-weighting of its Junior Gold Miners ETF, and ASX stock Firefinch (ASX:FFX) has picked up a seat at the table.

The latest data from the US-listed ETF ((NYSE:GDXJ) shows it holds a portfolio of 97 companies across a number of global jurisdictions.

By geography, around half those stocks are based in Canada, while Australia makes up the next highest weighting with 18 companies (around 18.5% of the total).

ETFs work similarly to managed funds which invest in various financial assets including shares, bonds, infrastructure and in some cases even other ETFs.

They offer simple diversified exposure to different sectors such as gold, technology and ESG investments. Globally, fund inflows to ETFs rose to a new record high above US$600bn in the first half of this year.
