Morningstar Sustainability Rating

The Morningstar Sustainability Rating, sometimes referred to as the “Globe Rating” due to the globes used in its scoring system, is a metric that evaluates the environmental, social, and governance (ESG) sustainability of mutual funds and exchange-traded funds (ETFs). This rating system provides investors with a way to compare funds based on their ESG practices and impact, ultimately helping them make more informed decisions that align with their values.

Overview

Morningstar, Inc., a leading provider of independent investment research, introduced the Sustainability Rating in 2016. The rating aims to equip investors with insights into how effectively the companies within a fund are managing their ESG risks relative to their peers. Given the growing interest in sustainable investing, this tool has become a valuable resource for assessing fund performance from an ESG perspective.

How the Rating is Calculated

The Morningstar Sustainability Rating is determined based on two primary factors: the ESG risk ratings of the companies within a fund and the level of controversy associated with those companies.

ESG Risk Ratings

Morningstar relies on data from Sustainalytics, a leading provider of ESG ratings and research. Sustainalytics assesses companies across various ESG dimensions, including:

Controversy Score

Sustainalytics also provides a controversy score, which reflects incidents that may have a negative impact on stakeholders, such as environmental spills, lawsuits, or company scandals. The score ranges from 1 to 5, with 1 indicating low controversy and 5 indicating severe controversy.

Fund Scoring Process

  1. Company-Level Assessment: Each company within a fund is assessed for ESG risks and controversies. These scores are weighted based on the company’s size (market capitalization) and its percentage of the fund’s holdings.
  2. Fund-Level Aggregation: The individual company scores are aggregated to provide an overall ESG risk score for the fund.
  3. Relative Ranking: Funds are then ranked relative to other funds within the same Morningstar Global Category, which groups funds with similar investment objectives.

The final rating is expressed as a number of globes, ranging from 1 to 5:

Benefits for Investors

Informed Decision-Making

Investors can use the Morningstar Sustainability Rating to assess the alignment of their investments with personal values and goals related to sustainability. By comparing the sustainability performance of different funds, investors can select those that better manage ESG risks and contribute to positive societal impact.

Risk Management

Funds with higher sustainability ratings often demonstrate better management of material ESG risks, which can translate to lower operational risks and potential for long-term outperformance. This makes the rating a useful tool for risk-averse investors looking to mitigate exposure to ESG-related issues.

Enhanced Transparency

The rating system promotes transparency by providing a standardized method for evaluating the ESG performance of funds. It encourages fund managers to articulate and improve their ESG practices, thus fostering a more sustainable investment landscape.

Challenges and Criticisms

Despite its benefits, the Morningstar Sustainability Rating system faces several criticisms:

Data Reliability

The rating relies heavily on data from Sustainalytics, which may face challenges such as data gaps, inconsistencies, or misreported information from companies. The accuracy of the rating is dependent on the quality and completeness of these data inputs.

Subjectivity in ESG Factors

ESG factors can be inherently subjective, and the importance of various factors may differ among investors. While the rating system provides a comprehensive view of ESG risks, it may not account for specific nuances or priorities held by individual investors.

Evolving Standards

ESG standards and metrics are continually evolving, which can make it challenging for rating systems to stay up-to-date and relevant. What is considered a best practice today might change in the future, requiring ongoing adjustments to the rating methodology.

Future Developments

Morningstar continues to refine and enhance its Sustainability Rating methodology to address these challenges. Future developments may include:

Integration of New Data Sources

Morningstar is exploring the incorporation of additional data sources to improve the accuracy and breadth of ESG assessments. This may include more real-time data feeds, alternative data sources, and enhanced controversy monitoring.

Enhanced Customization

There is potential for more personalized sustainability assessments that allow investors to tailor the ratings to their specific ESG priorities. This could involve customizable weightings for different ESG factors or more granular analysis of specific issues.

Collaborative Efforts

As the ESG landscape evolves, Morningstar collaborates with other industry stakeholders, including regulatory bodies, financial institutions, and ESG research organizations, to refine best practices and ensure the ratings remain relevant and impactful.

Conclusion

The Morningstar Sustainability Rating provides a valuable framework for evaluating the ESG performance of mutual funds and ETFs. By using this tool, investors can make more informed decisions that align with their sustainability values, manage risks associated with ESG factors, and contribute to the broader goal of fostering sustainable development in the investment landscape.
