Either would be helpful in diversifying your portfolio to incorporate an exposure to broad-based commodities.

This is a comparison of GSG vs DBC. Learn how to analyse which index fund is a better investment.

What are the drivers for Commodities?

A rise in inflation, tighter oil supplies, strong demand from the industrial sector and crop-friendly weather are some factors that can impact the prospects for commodity markets.

GSG: iShares S&P GSCI Commodity-Indexed Trust

The fund invests in a diversified group of commodities and tracks S&P GSCI Total Return Index. iShares S&P GSCI Commodity-Indexed Trust (the 'Trust') seeks to track the results of a fully collateralized investment in futures contracts on an index composed of a diversified group of commodities futures.

DBC: Invesco DB Commodity Index Tracking Fund

The Fund tracks the DBIQ Optimum Yield Diversified Commodity Index.

DBC uses futures contracts to maintain exposure and selects them based on the shape of the futures curve to minimize contango. It represents 14 commodities drawn from the Energy, Precious Metals, Industrial Metals and Agriculture sectors via futures contracts. The fund’s index aims to maximize the potential roll benefits in backwardation markets and minimize any loss from rolling down the curve in contango markets.

It does so by employing a rules-based approach when it rolls from one futures contract to another for each commodity. Rather than rolling based on a predefined schedule (e.g. monthly), the index rolls to futures (within the next 13) which, by its rules, generates the maximum implied roll yield. Structured as a commodity pool, investors should expect a K-1 at tax time. The fund and the index are rebalanced and reconstituted annually in November.

It's suitable for investors who want a cost-effective and convenient way to invest in commodity futures.
