Tal Lomnitzer, Portfolio Manager on the Global Natural Resources Team, discusses the strong demand for resources fueled by evolving global energy needs as well as the diversification merits of a long-term allocation to the asset class as part of a balanced portfolio.
- The team’s analysis suggests that resources equities have shown a negative correlation with the broader equity market over the long term, yet are capable of generating similar returns with lower volatility.
- In an environment of rising inflation, certain sectors such as mining, packaging and forestry can have a good correlation with inflation expectations and are beneficiaries of decarbonization.
- The prospects for resources companies are bright. Sustainable natural resources companies have a key role to play in supporting the transition to a more sustainable and low-carbon economy.
Note: this article was first published in October 2019. We have re-run the data in our analysis against the MSCI World Index to provide a more global perspective compared to the S&P 500® Index used previously. The key message remains – resources equities can be an effective portfolio diversifier.
The global natural resources sector is generally considered to be highly cyclical, being sensitive to the economic backdrop, resulting in a strong temptation among investors to time their entry and exit with the economic cycle. We sympathize. Getting the timing wrong can be a career-limiting decision while getting it right can be extremely rewarding, so it is natural to be captivated by the short cycle outlook. A myopic focus can, however, miss the significant benefits of taking a longer-term perspective.
We encourage investors to consider an investment in the resources sector over the long term ‒ that is, to think of resources as an investment rather than a trade. Unlike other segments of the market, resources equities (i.e., materials, energy and agriculture) have shown they can be negatively correlated with the broader equity market over the long term. Yet they are capable of generating similar returns.
Similar return with lower risk is considered by some to be a holy grail of investing ‒ resources, anyone?
Essential Building Blocks
Resources provide the essential and fundamental building blocks of economic development. While demand for some commodities like coal or oil is likely to plateau and decline, the demand for others is growing and looks set to rise. The renewable energy industry requires copper, lithium, cobalt, nickel, iron ore and silver. Digitization requires massive server farms and enormous quantities of energy. As the world strives toward a digitized, electrified and fossil fuel-free future, resources have an integral and essential part to play. There is a fundamental growing demand for future energy sources and nutrition that can only be met by the resources sector. As the world evolves, so does the need for different parts of the resources sector.
Benefiting from Negative Correlation over Time
A 2016 white paper by Lucas White and Jeremy Grantham at GMO showed that “resource equities provide diversification relative to the broad equity market, and the diversification benefits increase over longer time horizons.”1 We set out to test this hypothesis on a broader data set that includes agriculture. Building from their analysis, we disaggregated the U.S. market into its various sectors and ran correlations between the sectors and the MSCI World Index (“the market”) over various rolling time periods using data from February 1995 to February 2022 (see Exhibit 1).
We defined resources as an equally weighted index of mining, energy and agriculture, broadly similar to the S&P Global Natural Resources Index. The analysis shows that the linkage between resources equities, other sectors and the market is high over the short term but declines dramatically over the longer term. Indeed, over a rolling 10-year period, the correlation between resources and the broad market has actually been negative, whereas it stays positive and rises over time for other sectors.

Potentially Higher Reward for Less Risk?
Beyond the ongoing contribution to wealth creation and quality of life, resources have the attributes of an attractive investment class in their own right. As with gravity in the domain of physics, there are certain immutable laws of investment – in particular, the relationship between risk and reward. Our analysis suggests that by adding resources to an equities portfolio, it is possible to generate a similar return but with lower risk, as measured by volatility (standard deviation).
Taking inspiration from GMO’s white paper, our analysis of more than 25 years of historical data shows that when compared against the market, the average 10-year return of a portfolio consisting of 75% MSCI World Index and 25% resources has increased while the standard deviation (the risk) has dropped. Interestingly, the results are consistent though less dramatic if a 90% MSCI World/10% resources portfolio is used (see Exhibit 2). Unsurprisingly, combining these metrics into a Sharpe ratio shows a similar result.
Exhibit 2: An Allocation to Resources May Improve Risk-Adjusted Returns over the Long Term (10 Years)

Past performance does not predict future returns.
Quantum physics teaches that something can exist in two states. Matter is both a particle and a wave; resources equities are both cyclical and an effective portfolio diversifier. In Schrödinger’s words, “this would not embody anything unclear or contradictory.” The answer lies in the time frame: While resources are tied to the economic cycle in the near term, over longer time periods they tend to march to the beat of their own drum. Not everyone thinks in 10-year horizons, so we have re-run the risk/return analysis over rolling five-year periods using the same data and generated similar results.
To summarize, over five- or 10-year horizons, adding resources, including agriculture, as a core part of a portfolio is likely to engender better returns with lower risk. Instead of looking on the sidewalk for pennies, it is far better to look to the horizon for nuggets of gold.
Furthermore, in an environment of rising inflation, an investment in the resources sector has additional attractions. Mining equities have been shown to have a good correlation (i.e., positive relationship) with inflation expectations and can be considered to be a real asset play as we move into negative real rates. The sector is not being technically disrupted; in fact, it benefits from the disruption within the energy and mobility sectors. Renewables use much more copper or steel than fossil fuels, while electric vehicles require much more copper than combustion engines.
Similarly, packaging and forestry have a high correlation with inflation expectations and are benefiting from a move to e-commerce and the replacement of plastics with fiber-based packaging. There are many companies in the resources sector that appear well positioned compared to the rest of the market in terms of balance sheet strength, cash flow generation and dividends. The team believes current valuations appear attractive and a long term-investment could well be rewarding.
Resources Play a Key Role in Sustainability
We are optimistic about the prospects for natural resources companies, which are at the nexus of sustainable development and the decarbonization transition. While some resource sectors have potentially high environmental and social impacts associated with their extraction, production, manufacture and distribution, we believe that sustainable natural resource companies have a key role to play in supporting the transition to a more sustainable and low-carbon economy. In our view, companies that adhere to sustainable practices are best prepared for the future and are therefore more likely to deliver attractive risk-adjusted returns.

Volatility is the rate and extent at which the price of a portfolio, security or index, moves up and down, and is used as a measure of the riskiness of an investment.
Correlation measures the degree to which two variables move in relation to each other. A value of 1.0 implies movement in parallel, -1.0 implies movement in opposite directions, and 0.0 implies no relationship.
Standard deviation is a statistic that measures the variation or dispersion of a set of values/data. A low standard deviation shows the values tend to be close to the mean while a high standard deviation indicates the values are more spread out. In terms of valuing investments, standard deviation can provide a gauge of the historical volatility of an investment.
Sharpe ratio measures a portfolio’s risk-adjusted performance. A high Sharpe ratio indicates a better risk-adjusted return. The ratio is designed to measure how far a portfolio’s return can be attributed to portfolio manager skill as opposed to excessive risk taking.
Commodities (such as oil, metals and agricultural products) and commodity-linked securities are subject to greater volatility and risk and may not be appropriate for all investors. Commodities are speculative and may be affected by factors including market movements, economic and political developments, supply and demand disruptions, weather, disease and embargoes.
Natural resources industries can be significantly affected by changes in natural resource supply and demand, energy and commodity prices, political and economic developments, environmental incidents, energy conservation and exploration projects.
Sustainable or Environmental, Social and Governance (ESG) investing considers factors beyond traditional financial analysis. This may limit available investments and cause performance and exposures to differ from, and potentially be more concentrated in certain areas than the broader market.
Diversification neither assures a profit nor eliminates the risk of experiencing investment losses.
