What separates the best Australian small cap managers is how risk is allocated, sized and monitored

Every fund manager is looking for the next great stock. In Australian small caps, stock-picking alone is not enough to turn good stock calls into the consistent delivery of alpha. A key differentiator between managers is their approach to risk management. That is, the best managers embed a disciplined risk framework around their stock picking skills.

A philosophy built on quality, valuation discipline and risk management

Quality matters in small caps because it has been a persistent source of outperformance. This is intuitive - businesses with the potential to compound earnings growth over time require durable models, capable management and strong balance sheets. It is companies with these characteristics that are best placed to keep delivering, through one cycle and into the next.

For these reasons, quality is a common bias in many small cap portfolios. But quality alone won’t deliver consistent outperformance. Other elements necessary include valuation discipline and strong risk management. These features help good stock picking to pay off consistently. The quality factor can, and does, become over-priced at different points in a cycle and the drawdowns that result can be material. Valuation discipline is what keeps a manager from over-paying for exciting narratives and helps to limit these large drawdowns when regimes shift. Buying quality well, not just buying quality, is the harder and more valuable discipline.

Risk management is the second feature necessary to support consistency in performance. Macroeconomic swings and factor rotations can be significant drivers of market returns and few, if any, managers have repeatable skill in identifying these changing regimes. With increasing geopolitical risk, sovereign fiscal stress and fractured political systems, it is possible that such gyrations will become more frequent. To ensure that the gains from stock selection aren’t lost to these unforecastable effects, managers must be diligent in controlling their exposure to such factors.

There's a simple test worth applying to any small cap manager: is performance being driven by stock-specific insight, or by macro and factor exposures that came along for the ride? A process genuinely built around stock selection should be able to answer that question with evidence, not assertion.

A robust risk management framework is multifaceted, and it extends beyond the idiosyncratic or stock-specific risks identified through research. The Bell Australian Small Companies team’s risk management includes the following components:

• Discrete and deliberate risk allocation. The team’s key skill set is stock-picking and they spend the vast majority of their time understanding individual companies in substantial detail. It is logical then that the risk taken at a portfolio level should come primarily from stock specific risk. For this reason, the team ensures at least 80% of the risk budget is consumed by idiosyncratic risk.
• Position sizing. Fundamental equity investing is about assessing and understanding mispricing. But it is conducted in an environment of imperfect information. Even the most thorough research process is only pushing probabilities slightly in one’s favour. Moreover, the most diligent research process cannot cater for the myriad of exogenous and unforecastable variables that can impact a stock’s valuation. For this reason, the team is extremely strict on position sizing, allowing a maximum active weight of 4%.  This is designed to allow meaningful exposure to an attractive, high conviction opportunity in a controlled manner, so that the impact on the overall portfolio is limited if the team is wrong.
• Monitoring and controlling factor and macroeconomic exposures.  The team monitors variables it has no compelling insight into so that they do not inadvertently create outsized risk in the portfolio. Variables such as macroeconomic shocks, currency movements, oil prices and style rotations are difficult to predict consistently. The team limits their potential impact by controlling exposure to them.
• The use of risk models to ensure there are no unintended biases. A portfolio of 30-70 names contains thousands of correlations, and the sum of these correlations can result in biases or exposures that aren’t identifiable without comprehensive risk models. A recent example of how the accumulated impact of individual stock bets can introduce outsized risk was seen in the portfolio’s exposure to gold. Despite an active exposure of less than 1% to the gold sector, due to correlations across other stocks and sectors, the risk model showed gold accounting for approximately 8% of the risk budget. The team does not believe it has insight into the short-term gyrations of gold prices and for this reason would not want an excessive allocation of risk to this variable. A 1% active bet wouldn’t appear to be risky – but in combination with others, it was adding far more risk than would have been assessed without the use of these models.

Allocating risk to where the team has an edge (i.e. stock selection), rather than variables that have unforecastable dynamics, ensures the outcomes for the portfolio will come from the areas where the team has insight and where they have invested their time understanding.

Three beliefs that shape the process

Markets are inefficient

Bottom-up, fundamental research can identify mispriced companies, and individual stock selection is a genuine, repeatable edge in a market that is less well researched. The best small cap managers treat this as the primary source of portfolio returns, not a byproduct of broader market moves.

Quality is a defining feature of small caps

As noted, it has been an enduring source of alpha. But it is also an excellent way to manage risk at a stock level. Small companies, by virtue of being less mature, have a wider range of potential future outcomes. Add to this more limited access to capital and it is unsurprising that small caps can have more dispersed outcomes compared to large caps. By introducing quality upfront at an individual stock level, this risk can be mitigated.

Stock picking should drive outcomes

The edge in small caps lies in understanding individual businesses, not in forecasting macroeconomic conditions or shifts in factor performance. A well-built process puts most of the portfolio risk where that edge is: stock selection. Macro and factor exposure should be managed deliberately, so they support the stock-selection thesis rather than dilute it.

The four-stage process

Here's what that discipline looks like applied using the Bell Australian Small Companies team’s process as an example:

1. Quality assessment: every company is assessed against five factors, two qualitative (business model durability and management capability) and three quantitative (return on equity, relative earnings stability and balance sheet strength).
2. Fundamental research and valuation: a bottom-up process focused on value drivers, execution risk and competitive dynamics, informing the team's own view of intrinsic value and total return potential.
3. Portfolio construction: bottom-up insights are combined so that exposure to any given theme, sector or style factor is a conscious decision, not an accident of stock selection. Aggregate exposure to any stock, sector or factor is controlled.
4. Risk assessment: a continuous overlay across the whole process, covering both stock-specific and portfolio-level risk.

Two dimensions the process is built around

Stock-specific conviction reflects how strongly the team backs an individual thesis. That conviction is built through research depth and translated into a defined share of the portfolio's risk budget for any single stock, so the biggest ideas get the biggest say in outcomes, in a considered and deliberate way.

Portfolio-level design is what turns a collection of good stock decisions into a coherent portfolio. The team actively manages how positions combine (sector weights, factor tilts and macro sensitivities) so the portfolio's overall risk budget is allocated deliberately, with a clear ceiling on how much can come from these broader, less controllable sources.

Position sizing: conviction, not consensus

The largest active weights go to companies combining quality, an attractive valuation, high conviction in the thesis, and a supportive fit within the portfolio's overall design. That's how the best ideas earn the biggest say in outcomes.

It also reflects a clear-eyed view that investing is a game of probabilities, and sizing positions to conviction, rather than treating every idea equally, is what allows a portfolio to compound the value of genuine insight over the long term.

What it all comes down to

Stock selection identifies the opportunity. How risk is allocated, sized and monitored determines how much of that insight shows up in the portfolio. As at 30 September 2026, the split between stock selection and factor risk in the Bell Australian Small Companies team portfolio was 81% to 19%. On the same date, the portfolio also showed a higher return on equity, a lower forward PE and lower debt than the benchmark.

For investors assessing small cap managers, the questions worth asking go beyond headline performance:

• How is tracking error decomposed between stock selection and factor exposure?
• Is position sizing deliberately calibrated to conviction, or applied uniformly?
• Can strong performance be explained by specific investment decisions, rather than a favourable market backdrop?
