Your Portfolio May Not Be Positioned for a Commodity Supercycle

Commodity markets may be entering a prolonged upswing, while broad equity portfolios remain underexposed to the businesses supplying essential physical inputs.

• Energy represents less than 4% and materials less than 2% of the S&P 500 as of September 30, 2026, roughly one-third to one-half of their average weights over the past three decades.
• AI, electrification, batteries, defense and industrial investment require copper, aluminum, lithium, nickel, graphite and other physical inputs.
• Mines entering production in 2020–2024 took an average of 17.8 years to develop, nearly three times the lead time for mines that began operating in the 1990s.
• Historical commodity upswings lasted roughly nine years on average; if the cycle that began in 2021 follows that pattern, it could have another three to four years to run.
• The Federal Reserve projects core PCE inflation at 3.4% in 2026, 2.5% in 2027 and 2.2% in 2028, remaining above its 2% target throughout the period.

Takeaway: Investors should reconsider commodity exposure as a source of diversification, inflation sensitivity and participation in real-asset demand, while recognizing that futures, physical funds and commodity equities have different structural, tax and risk characteristics.
