When it comes to the world of investing, people want to make sure that their money is going to the right place. Over the past few years, exchange traded funds, or ETFs have been gaining in popularity. They act much like a mutual fund and an index fund combined, but you are able to move ETFs daily, much like a stock on the stock market. You can also get an ETF that is focused on one specific item. People often get what is called a commodity ETF, which are made up of futures or asset-backed contracts. The contracts will represent the commodity and will track the performance of the particular product, but the actual good is not in the ETF. So, if you were to buy a copper ETF, you would have a commodity ETF. You would not be buying copper products, but you would be buying an ETF that consists of assets backed by copper. Copper has gotten back on track as of 2015, so it may be a good time to invest in it. Here is a list of three popular copper ETFs that you may want to consider investing in.

1.) First Trust ISE Global Copper Index (CU)

This copper fund follows the ISE Global Copper Index, and the holdings in the fund and index represent a wide range of stocks. These stocks are of companies that are involved in the copper mining industry. Some of the holdings include Southern Copper Corporation and Xsrata. The mining companies that CU has holdings with mine copper, but some of the mining companies also operate with focuses on gold, silver and other metals. They decide which stocks are involved by looking at the revenues that are obtained from the sale of copper from each firm.

2.) Global X Copper Miners (COPX)

This ETF invests in copper miners that concentrate solely on copper. This is unlike many other ETFs who invest in miners that do mine copper, but other metals as well. According to ETF Database, as of 2012, they had $36 million in assets under management, and is five points cheaper than CU (listed above). Some of the fund’s holdings include Sandier Resources (SFR) and Southern Copper (SCCO). It has an expense ratio of 0.65%, and has a lower risk than other ETFs, like the other two that are listed. If you want a company with the main focus on copper, COPX may be the ETF for you.

3.) United States Copper Index (CPER)

This is a futures-based product that is structured as a publicly-traded limited partnership. This eliminates exposure to the credit risks that come along with other ETFs. It is traded on the NYSE ARCA (New York Stock Exchange Archipelago). It uses observable market prices at the end of each month to select its futures contracts. This ETF is designed to reflect the price of the Summer Haven Copper Total Return Index. The Summer Haven copper index is used as a benchmark for copper prices. This fund has an expense ration of 0.65%.
