There’s more than one way to invest in copper. In addition to buying shares of copper stocks, investors can gain exposure through copper exchange-traded funds (ETFs) or copper exchange-traded notes (ETNs).
For the uninitiated, ETFs are securities that trade like stocks on an exchange, but track an index, commodity, bonds or a basket of assets like an index fund. In the case of base metal copper, there are various options — an ETF can track specific groups of copper-focused companies, as well as copper futures contracts or even physical copper.
ETNs also track an underlying asset and trade like stocks on an exchange, but they differ from ETFs in some ways. Specifically, ETNs are more like bonds — they are unsecured debt notes issued by an institution, and can be held to maturity or bought and sold at will. The main disadvantage to be aware of is that investors risk total default if an ETN’s underwriter goes bankrupt.
The copper outlook is strong as demand rises and concerns about supply increase as the energy transition gains traction. This has caused many investors to wonder how to take advantage of the potential in the copper market.
