Market Variability and Tracking Error Insights
The fluctuations in tracking error reveal significant variations over time, particularly influenced by market conditions, especially during the years 2022 and 2023. For instance, the MSCI World Climate Change Index exhibited a rolling 12-month average tracking error that oscillated between approximately 100 basis points and 400 basis points throughout a five-year span. Notably, in 2023, there was a divergence where the climate change index moved further away from its parent index, while the selection index maintained a closer alignment. Understanding the reasons behind these fluctuations becomes complex due to the intricate and interconnected sustainability criteria within each methodology. Our findings indicate that sustainable passive strategies present diverse and volatile tracking-error profiles, which introduce inherent risks to investment portfolios.
Performance Risks Linked to Sustainability Strategies
One primary risk associated with these strategies is performance risk. This has been particularly evident during periods of adverse market conditions, such as the energy supply shocks and rising inflation and interest rates experienced in 2022-2023. This risk is often related to the investment horizon implied by a strategy’s sustainability focus. For example, themes like climate transition, which unfold over an extended period, rely on long-term sources of excess returns that may not align with immediate performance drivers. Without strategies to mitigate volatility, passive sustainable approaches may struggle against cyclical market dynamics and short-term fluctuations.
Transparency and Control Risks in Sustainable Indices
Another crucial aspect to consider is the necessity of addressing transparency and control risks. Many sustainable indices incorporate a mix of complex and interrelated sustainability factors. The intricate nature of these parameters and their interdependencies can obscure their effects on the risk and return profiles of investment strategies aiming to follow these indices. It is our belief that without a comprehensive understanding of how sustainability criteria shape portfolio composition and performance, effectively managing the associated risks may prove challenging.
Strategies for Managing Sustainability-Related Risks
Addressing sustainability-related risks in passive equity strategies requires fulfilling three essential objectives: systematically managing the risks posed by sustainability criteria, reducing performance volatility, and ensuring transparency regarding the attribution of performance impact. We propose that an Alpha Enhanced approach can assist investors in reaching these goals. These strategies are crafted to create opportunities for outperformance through investments that diverge from a benchmark while maintaining risk within acceptable parameters.
Implementing Alpha Views to Mitigate Risks
An investment manager adept at implementing alpha views that are minimally correlated with a strategy’s sustainability-related tilts can effectively manage the risks arising from sustainability criteria. By integrating an alpha component, a strategy can mitigate the influence of sustainability-related biases and reduce short-term volatility, thereby enhancing resilience against cyclical market fluctuations. In performance analysis, disentangling the effects of sustainability criteria from alpha views can be intricate, as the two elements are often intertwined. Therefore, a quantitative approach that sequences the implementation of sustainability criteria alongside the alpha-engine overlay is essential.
Optimizing Tracking Error and Performance
The initial phase involves minimizing the tracking error caused by sustainability criteria, thereby lessening the impact of related tilts and biases. The subsequent phase aims to optimize the risk-adjusted performance of the portfolio by integrating a systematic alpha engine that operates within a tracking-error budget defined by the client. This sequenced methodology balances the active risks introduced by sustainability criteria and the alpha engine, potentially resulting in a more robust sustainable equity solution.
Diversification Benefits and Cost Efficiency
Incorporating an alpha engine serves to effectively manage performance risk and attenuate the impact of sustainability parameters on returns. Given that passive sustainability strategies often depend on unique performance patterns stemming from sustainability criteria, a moderate alpha component can enable investors to harness more systematic sources of excess returns, potentially counterbalancing the overall return profile of the portfolio. By integrating alpha views that are independent of sustainability criteria, this approach can provide diversification advantages within risk budgets, as some sustainability-related risks may be leveraged for alpha generation. Consequently, the total tracking error from this two-step process is lower than the cumulative tracking error incurred from each step if executed separately, enhancing the portfolio’s risk-adjusted return profile.
Enhancing Transparency and Decision-Making
This methodology can also lead to improved cost efficiency by optimizing active risk allocation and offering the potential for moderate excess returns that typical passive index replication strategies may not provide. Importantly, the separation of each step allows for a clear distinction between excess returns and tracking error derived from systematic stock selection versus tailored sustainability criteria. We consider this transparency a valuable asset for investors, offering clearer insights into how their sustainability goals influence portfolio risks and returns, ultimately aiding them in refining their sustainability parameters while keeping performance considerations in view.
