Commodities Trading Guide — How to Invest in Raw Materials and Resources
Commodities are raw materials used to produce goods and services. They offer portfolio diversification, inflation hedging, and exposure to global economic growth. Commodity returns have low correlation with stocks and bonds.
Major commodity sectors: energy (crude oil, natural gas, gasoline, heating oil, coal, uranium), metals — precious (gold, silver, platinum, palladium) and base/industrial (copper, aluminum, zinc, lead, nickel, tin, iron ore, steel), agriculture (corn, wheat, soybeans, coffee, cocoa, sugar, cotton, rice), and livestock (live cattle, lean hogs, feeder cattle). Investment methods: futures and options (direct commodity exposure through exchange-traded contracts, require a brokerage account with futures trading approval, have margin requirements and roll costs), exchange-traded funds (ETFs and ETNs — most accessible for individual investors, track commodity indexes or single commodities, examples include GLD, SLV, USO, DBC, GSG, and sub-sector ETFs), commodity-focused mutual funds (diversified across commodities, professionally managed, higher expense ratios than ETFs), commodity stocks (equities in mining, energy, and agricultural companies — provides indirect commodity exposure with company-specific risk added), physical ownership (holding physical gold, silver, and platinum bullion — requires storage and insurance, no counterparty risk), managed futures funds (CTA funds that trade commodity futures actively, high minimums and fees, can provide uncorrelated returns), and commodity pools and limited partnerships.

Benefits and Risks
Benefits of commodity investing: Inflation hedge (commodity prices rise with inflation — gold during high inflation, energy and agricultural commodities during inflationary periods), portfolio diversification (commodity returns have low correlation with stocks and bonds — typically 0.2-0.4 correlation with equities, negative correlation during some market environments), upside from economic growth (commodity demand rises with industrial production and infrastructure spending), and supply constraints can drive significant price appreciation (geopolitical events, weather, production cuts). Risks: Price volatility (commodities are more volatile than stocks — annualized volatility of 20-40% vs 15-20% for stocks), no income or yield (commodities do not pay dividends or interest — total return comes only from price appreciation), contango and roll yield (long-term futures positions can lose money from rolling contracts forward when the futures curve is in contango — future prices higher than spot), storage and insurance costs (physical commodities have carrying costs), leverage risk in futures (high leverage can lead to significant losses), commodity-specific risks (weather for agriculture, geopolitical for energy, mining disruptions for metals), and regulatory and tax complexity (futures are subject to 60/40 tax treatment — 60% long-term capital gains and 40% short-term gains; physical precious metals are taxed as collectibles at 28% maximum rate). Commodity investing is best suited for portfolio allocation of 5-15% rather than concentrated bets. Commodity allocation calculator →
FAQs
What is the best way to invest in commodities for beginners?
For beginners, broad commodity ETFs and ETNs are the best entry point. Invesco DB Commodity Index Tracking Fund (DBC) provides diversified exposure to energy, metals, and agriculture. iShares S&P GSCI Commodity-Indexed Trust (GSG) tracks a broad commodity index. For precious metals, SPDR Gold Shares (GLD) and iShares Silver Trust (SLV) are the most liquid and accessible. Commodity mutual funds and commodity-focused equity funds (mining, energy) are also beginner-friendly but add company risk. Avoid futures trading until you understand margin, contango, and roll costs. Start with 5-10% of your portfolio in commodities through ETFs. Rebalance annually. Do not try to time commodity markets — they are notoriously difficult to predict.
How do commodities perform during inflation?
Commodities are one of the best-performing asset classes during periods of high and rising inflation. During the 1970s inflationary period, commodity returns significantly exceeded stock and bond returns. Gold performs best during high inflation (1970s, 2020-2022). Energy commodities (crude oil, natural gas) perform well when inflation is driven by energy costs. Agricultural commodities perform well when food prices drive inflation. Broad commodity indexes have a correlation of 0.5-0.8 with CPI during inflationary periods. TIPS (Treasury Inflation-Protected Securities) and commodities together provide a comprehensive inflation hedge. The correlation between commodities and stocks increases during deflationary periods and decreases during inflationary periods — making commodities an effective hedge when inflation is the primary economic concern.
What is contango and backwardation?
Contango is when futures prices are higher than the current spot price — the normal state for most commodities due to storage, insurance, and financing costs (cost of carry). Contango creates negative roll yield for long-only futures investors (you sell low and buy high when rolling contracts). Backwardation is when futures prices are lower than the spot price — typically occurs when there is a supply shortage or high demand for immediate delivery. Backwardation creates positive roll yield (you sell high and buy low when rolling). The difference between contango and backwardation significantly affects long-term commodity returns. Broad commodity ETFs are most profitable when the commodity index is in backwardation. When commodities are in contango, short-dated futures ETFs may perform better than longer-dated ones.
