Adam Hetts and Sabrina Geppert from the Portfolio Construction and Strategy Team examine whether unintended risks are introduced by a shift to ‘sustainable’ investing and the scarcity of allocation options.
- There is an inconsistency of risk profiles between traditional and sustainable model portfolios. This is arguably because the asset management industry’s product offering is still catching up to advisor demand for sustainable investment solutions.
- Differences based on more limited sustainable investment availability are not just attributed to regions but can also be influenced by a style and sector tilt, all of which can have an impact on returns.
- These are important considerations for advisors in maintaining asset allocation risk consistency across model portfolios and finding a sustainable method to accomplish clients’ sustainable investing goals.
Sustainable investment considerations are currently a major catalyst shifting the investment landscape. They carry myriad, intended influences on one’s asset allocation including the application of a forward-looking view accounting for the varied impact of climate change across global asset classes and sectors. However, what if this relatively new investment landscape is also creating the potential for other, unintended, asset allocation risks? What if many of the new sustainable model portfolios that advisors are building as a service to their clients are actually unrecognisable to their traditional models when it comes to regional biases, style drifts, and sector concentrations? What are these unintended risks introduced by a shift to ‘sustainable’ investing?
At Janus Henderson, our Portfolio Construction and Strategy (PCS) Team sees this risk dilemma as prevalent in client consultations with UK advisors. We provide consultations free of charge with instant portfolio ‘look through’ analysis that, when attempted independently, can be timely and complicated to assess. These assessments are currently showing risks and inconsistencies in sustainable model portfolios that may have been masked by recent strong equity performance in certain sectors and regions. We believe that a case study outlined below from a recent UK client consultation is representative of the issues many advisors face.
The scarcity of sustainability
If our main concern is the inconsistency of risk profiles between traditional and sustainable model portfolios, we should begin by focusing on the root cause of this inconsistency. This, in our view, is that the asset management industry’s product offering is still catching up to advisor demand for sustainable investment solutions.
For example, an advisor investing in Europe ex-UK equity for their traditional model portfolio has a plethora of solutions available. That same advisor looking to mirror this selection in their sustainable model portfolios is limited to a much smaller selection. Compared to traditional Europe ex-UK equity, the sustainable options are severely limited with only 5.0% of the number of funds and 5.3% of the assets under management (AUM) as shown in Figure 1. There is a similar discrepancy within global fixed income.

Granular or global?
This availability challenge for advisors makes it easy to understand why many sustainable model portfolios take a different approach to traditional model portfolios. If, for example, an advisor owns a Europe ex-UK equity fund in their traditional model portfolio and wants to select a sustainable European equity ex-UK fund but there are none available for the sustainable model, the likelihood is they will transition to a global sustainable fund. The result is often that the different approach presents a different set of, often unintended, risks.
The example portfolios in Figure 2 show exactly this phenomenon in our recent UK client consultation case study. Within equities, the traditional model portfolio includes fewer global strategies, with more granular regional equity allocations, while the sustainable model portfolio relies more on global equity. Within fixed income, the phenomenon is the opposite with the traditional model portfolio fixed income allocation split between UK and global fixed income and the sustainable model with all its fixed income allocated to the UK. As we will discuss, we believe these asset allocation shifts – and therefore risk shifts – are attributable to the relative paucity of sustainable strategies in certain categories, which has forced the advisor in this case study to find alternative categories.

Different risks mean different returns
The inconsistent asset allocation creates a meaningful return divergence. The sustainable model portfolio has fared well in the last year with a calendar return of 13.4% in 2020, returning approximately five percentage points more than the broader ‘traditional’ portfolio (see Figure 3).

Past performance is not a guide to future performance.
The scarcity of sustainable regional equity strategies is one of the many reasons for the sustainable model being underweight regional equity strategies and overweight global equity strategies. This introduces meaningful return differentials as shown in Figure 4.

The differences between traditional and sustainable solutions are not just attributed to regions. It is interesting to note that, even when controlling for regional differences (eg. global versus UK), a sustainable implementation alone can often introduce a style and sector tilt.
Comparing the sector exposures of global and UK funds versus their sustainable counterparts, we see global sustainable equity funds tend to have a stronger bias towards the technology and healthcare sectors (Figure 5). These sectors generally outperformed in recent years, especially in 2020 as ‘beneficiaries’ of the COVID-19 crisis. Our analysis shows that managers of sustainable funds have typically been less exposed to cyclical sectors, such as consumer cyclicals, energy and communication services, relative to broader equity funds.

Taken to the extreme, a swap from traditional UK equity to a sustainable global equity would introduce a significant sector tilt (Figure 6):

The unfortunate reality today is that selection is still limited for many portions of advisors’ sustainability asset allocation. The appropriate risk management tools and asset allocation perspective is indispensable for advisors focused on building sustainable model portfolios while limiting unintended asset allocation tilts, biases, drifts, and other risks. These, in our view, are important considerations in maintaining asset allocation risk consistency across model portfolios and finding a sustainable method to accomplish your clients’ sustainable investing goals. We would be delighted to contribute to conversations on the issue.
