Australian small cap resource stocks are often viewed as more speculative relative to their industrial counterparts. While historical returns generated by Australian small resources have been more volatile, periods of ‘super-normal’ returns have been demonstrated, resulting from outperformance in select commodity cycles.
The ability to consistently pick commodity cycles is inherently difficult and not a focus of our investment process. However, we believe there is significant alpha-generating potential at a stock specific level, although investors need to be selective at the smaller end of the Australian small resources market.
Small resources sector allocation and underlying commodity exposures have varied over different periods
The Resources sector allocation within the Australian small caps market, as measured by the S&P/ASX Small Ordinaries Index, has varied significantly over time. Over the past 20 years, the Resources sector allocation peaked at approximately 45% in 2010, coinciding with the Chinese commodity super cycle, and bottomed at approximately 12% weight in 2015. The current weighting is approximately 29% (as of end-March 2025), which is broadly at the mid-point of recent history. The quality of resources companies included in the S&P/ASX Small Ordinaries Index has improved over time with a shift away from exploration companies to more producers currently.
Looking at underlying commodity exposures, the dispersion has been volatile. This includesthe focus on steel and metal related commodities fuelling China’s infrastructure boom over the 2005–2010 period, the metals focus supporting the electric vehicle/lithium boom over the 2021–2022 period, and the gold bull market over the 2024–2025 period to date.

As compared to Australian large caps, the smaller end of the market currently has a higher index weight percentage allocation to the Resources sector. Large cap resource stocks are dominated by bulk commodities — most notably iron ore, and to a lesser extent, coal. Demand for these commodities is typically driven by global economic conditions, particularly Chinese economic growth, and stimulus measures, which can be difficult for investors to predict. In contrast, smaller resource companies offer greater diversity in terms of commodities, geographic exposure, and stages of the project cycle. Small resources also tend to have more exposure to high-growth, emerging themes such as the electric vehicle revolution, the energy transition, increased demand for battery and industrial metals and growing interest in uranium.

In addition, Australian small-cap managers that allocate to resources have been major beneficiaries of the recent surge in the gold price, which has boosted the performance of Australian small-cap gold miners. This is due to the substantial leverage associated with commodity prices, coupled with easing cost pressures and robust free cash flow generation. As at the end of March 2025, the gold miners represent approximately 17% of the S&P/ASX Small Ordinaries Index.

Small resources’ out-performance typically comes with select commodity cycles
The returns generated by Australian small resources vary widely on a calendar year basis. However, surprisingly, Australian small resources have outperformed Australian small industrials in 54% of calendar years and on a cumulative basis over the past 25 years.
There have been periods of ‘super-normal’ returns for small resources, driven by commodity outperformance from select commodity cycles. Performance mean reversion is typically observed between these select commodity cycles. Notable commodity cycles include the Chinese Industrial Commodities Super-Cycle (2005–2010, ex-GFC period), Electric Vehicle/ Lithium Boom (2021–2022) and Gold Bull Market (2024–2025 year-to-date).

Going forward, small resources offer higher earnings growth expectations relative to Australian large resources – this is driven by the higher gold and lower bulk commodity exposures.

Australian small-cap managers’ resource positioning and outperformance patterns
Many Australian small-cap managers invest in industrial-only companies despite typically being benchmarked against the S&P/ASX Small Ordinaries Index. Since 2017, the rolling 3-year performance of S&P/ASX Small Industrials Index relative to the benchmark has been mostly benign although has experienced material dispersion over the 2007-2011 and 2013–2016 periods. Since 2000, holding a passive small industrials portfolio had a tracking error of 5.7% p.a. relative to the S&P/ASX Small Ordinaries (Total Return) Index.

This structural Resources sector underweight by the Australian small cap manager universe is clear given the historical median alpha generation being negatively correlated with Australian small resources relative performance (correlation -0.7). This increases the risk of industrial-only Australian small-cap managers generating alpha during extended periods where resources outperform industrials.

In addition, the number of constituents in the small cap resources sector is growing given increasing dual stock listings and the strong Initial Public Offering (IPO) pipeline. On the other hand, several small industrial companies have been taken over and/or delisted with minimal IPO activity to replenish stock numbers. This increases the risk of a shrinking opportunity set for industrial-only Australian small cap managers.
Resources stock considerations for the Maple-Brown Abbott Australian small caps strategy
We define ourselves by our ‘earnings drive share prices’ investment philosophy with a company’s share price performance driven by medium-term earnings delivery and the sustainability of the earnings delivery being an important driver of long-term performance. In addition, we are driven by discovering undervalued Australian small companies with idiosyncratic exposures.
We believe these opportunities can be exploited across the entire Australian small companies’ universe, including both industrial and resource exposed companies, which is a key differentiator relative to many of our peers.
We do not make commodity calls (we use consensus forecasts for commodity pricing in our stock models, and run various scenarios using spot price and downside price assumptions to assess the robustness of a company’s balance sheet) rather focusing on idiosyncratic exposures at the stock level, which we believe is the most reliable source of alpha generation at the smaller end of the market. Exposure to both industrials and resources is expected to result in a smoothening of the strategy’s alpha generation potential over time relative to the S&P/ASX Small Ordinaries Index and peers.
Given the inherent risks of resource companies, we are highly selective with a key focus on producing companies (or those companies close to production) with strong management teams that have a track record of meeting/exceeding expectations. Our process screens out exploration companies in addition to those companies in the development phase that are not expected to be in production within our investment horizon of 2–3 years. This results in the strategy having a structural underweight to the Resources sector.
Summary
In summary, we believe investors should not shy away from the heightened volatility of Australian small resources but rather embrace the significant alpha generating potential. However, investors need to be selective and look to employ active Australian small cap managers that have a strong track record of outperformance in the resources sector.
