Materials sector offers defensive traits amid inflation risks

The chart illustrates that the Materials sector has generally performed well during periods of rising inflation. The chart compares the Materials sector’s performance against the Producer Price Index (PPI) over the past three years. As of June 30, 2023, the S&P 500 Materials Index level was 522, and the PPI year-over-year change was 0.3%. As of May 29, 2026, the S&P 500 Materials Index level was 639, while the latest PPI year-over-year change for April 2026 was at 6.0%.Sources: FactSet and Wells Fargo Investment Institute. Monthly Index Level data is from June 30, 2023 – May 29, 2026; monthly PPI data is from June 2023 - April 2026. PPI = Producer Price Index. The S&P 500 Materials Sector represents companies within the S&P 500 Index that are classified within the Materials sector based on Global Industry Classification Standards (GICS). S&P 500 Materials Sector Index Level is as-of the last trading day of each month. An index is unmanaged and not available for direct investment. Past performance is no guarantee of future results.

Cyclical and secular forces improve the Materials sector’s outlook

While Materials is a highly cyclical sector with strong operating leverage to the global economy, it also offers defensive traits that can help reduce the near-term risks of accelerating inflation to equity portfolios. We believe that geopolitical dynamics are increasing the focus on supply chain resilience, supporting structurally higher pricing power and improving reinvestment opportunities for many companies within the sector.

The Materials sector has significant international exposure, and we view current U.S. trade policy and tariffs as a net benefit. The renewed focus on domestic supply chains is creating additional demand and opportunities for U.S. expansion. As shown in the chart, the sector has generally performed well alongside rising producer price inflation.

What it may mean for investors

We recently upgraded the Materials sector to favorable. Within the sector, we favor Industrial Gases for high margins, consistent pricing power, and diversified end-market demand; Construction Materials for potential infrastructure and heavy non-residential construction tailwinds, including data centers; and Specialty Chemicals for strong margin resilience through cycles. Overall, we believe each subsector offers attractive quality characteristics.

Risk Considerations

Each asset class has its own risk and return characteristics. The level of risk associated with a particular investment or asset class generally correlates with the level of return the investment or asset class might achieve. Stock markets, especially foreign markets, are volatile. Stock values may fluctuate in response to general economic and market conditions, the prospects of individual companies, and industry sectors. Sector investing can be more volatile than investments that are broadly diversified over numerous sectors of the economy and will increase a portfolio’s vulnerability to any single economic, political, or regulatory development affecting the sector. This can result in greater price volatility. Materials industries can be significantly affected by the volatility of commodity prices, the exchange rate between foreign currency and the dollar, export/import concerns, worldwide competition, procurement and manufacturing and cost containment issues.
