SRA Fund Quality Ratings: Ratings to Screen Funds and Construct Portfolios

Access our SRA Fund Quality Ratings, an evaluation of sustainable funds that combine qualitative and quantitative elements expressed along a five-point scale that runs from A (highest quality) to E (lowest quality). Fund quality ratings are assigned to the major investment categories across the focused long-term sustainable investing universe consisting of mutual funds and ETFs and may be used in constructing and monitoring investment portfolios consisting entirely or partially of sustainable funds. Once assigned, ratings are updated on a periodic basis.

SRA Resources and Tools: Asset Allocation, Portfolio Creation, Monitoring and Related Tools

Investors and financial intermediaries can access and review various resources and tools that will be updated, as required, and expanded to include additional related resources and tools over time. Currently available, for example, is a Risk Tolerance Investor Questionnaire for assessing an investor's financial profile, including both their investment time horizon and risk tolerance. Responses to the questionnaire produce one of five investor profiles and corresponding asset allocations. Another available tool is our Sustainable Investor Preferences Questionnaire designed to assess an investor’s interest in and preferences for sustainable investing. The analysis and resulting profile allow investors and financial intermediaries to reflect and translate an investor’s individual sustainable preferences into a tailor-made investment program that fits into a broader financially oriented asset allocation strategy.

SUSTAINABLE INVESTING SOLUTIONS THROUGH MUTUAL FUNDS AND ETFs

Getting Started with Sustainable Investing

Many questions have surfaced in recent years regarding sustainable and ESG investing. Here, investors and financial intermediaries will find essential materials that describe the various approaches to sustainable investing and their practical implementation.

Sustainable investing is an approach that incorporates ESG considerations, i.e. environmental, social and governance factors, into investment decision making with the dual aim of achieving financial returns and positive social and environmental outcomes over time. While sustainable investment strategies vary and have thus far defied universally accepted definitions, most practitioners agree that sustainable investing refers to a range of strategies that combine traditional investment approaches with environmental, social, and governance (ESG) insights. This contributes to a more comprehensive analysis, better investment decisions in terms of risks and opportunities and an alignment of values based on the preferences expressed by investors.

The range of sustainable investing strategies fall into the following broad categories: Values-based investing, screening and exclusions, impact investing, thematic investing, and ESG integration. These approaches are not mutually exclusive and, in conjunction with each of these approaches, investors may also adopt various issuer engagement procedures covering stock holdings as well as bonds, and proxy voting practices. It’s important to remember that sustainable investing approaches and practices will continue to evolve.
In addition to periodic updates regarding sustainable investing and how this form of investing is evolving, investors and financial intermediaries interested in implementing a sustainable investing approach will also find source materials that cover basic investing themes as well as asset allocation strategies, providing a holistic view for portfolio construction.

Why focus exclusively on sustainable investing?

The landscape of sustainable investing has seen rapid growth in recent years, marked by an increasing number of investors, expansion in the number of investment managers operating in this market segment, expansion in the number and type of investment product offerings, and a significant accumulation of assets under management. This growth has occurred during a time when sustainable investing has continued to evolve but without the benefit of widely accepted sustainable investing frameworks, definitions, and rules.   In turn, this has contributed to confusion and misunderstanding regarding the true meaning of sustainable investing, and related to this, the financial and non-financial expectations or outcomes associated with sustainable investment product offerings.

 

A particular area of misunderstanding has been the fact that in the process of pursuing financial goals and objectives as well as sustainability preferences, certain sustainability goals, or non-financial-oriented goals, may require investors to accept some trade-offs between the achievement of their sustainability preferences and their financial outcomes.  These trade-offs will vary in line with the sustainable strategy that investors may wish to implement. Fortunately, these trade-offs can be measured, and investors can decide on the risk-return trade-offs they are willing to accept to achieve their financial and sustainability preferences.         

 

Affecting a broad range of participants, including investors, regulators, managers, politicians, and other stakeholders, it has become increasingly difficult to differentiate between various funds and their stated sustainable strategies and intended outcomes, if any. This makes it more challenging for investors and financial intermediaries to align investment products with the sustainable goals, objectives, and values expressed by investors. As sustainable products continue to evolve and expand in number, there is a growing risk that fund strategies might diverge from investor expectations, a phenomenon commonly known as “greenwashing,” or may not align with investor beliefs or values, potentially leading to disappointments or, in severe cases, redemptions and even litigation. The recent politicization of ESG is, in part, yet another manifestation of this complex issue.

By closely monitoring, scrutinizing, and reporting on these trends and developments, an independent, original, and research-driven information source, such as sustainableInvest.com, can provide invaluable support to investors, financial intermediaries, and other stakeholders. Our analysis aids them in effectively navigating the current state of confusion and misunderstanding prevalent in this dynamic sector of investing.

What is sustainable investing? Core Approaches Explained

Sustainable investing is an approach that incorporates ESG considerations, i.e. environmental, social and governance factors, into investment decision making with the dual aim of achieving financial returns and positive social and environmental outcomes over time. While sustainable investment strategies vary and have thus far defied universally accepted definitions, most practitioners agree that sustainable investing refers to a range of strategies that combine traditional investment approaches with environmental, social, and governance (ESG) insights. This contributes to a more comprehensive analysis, better investment decisions in terms of risks and opportunities and an alignment of values based on the preferences expressed by investors.

The range of sustainable investing strategies falls into the following broad categories:

Values-based Investing: A strategy based on the guiding principle of investments that align with a set of faith-based or religious beliefs, ethical, moral, environmental or social mandates, aimed at achieving a positive societal outcome. Typically, this approach is executed via negative screening, divestiture, or divestment from companies or sectors misaligned with specific values.

Screening and Exclusionary Investing: This involves the overweighting or underweighting of stocks, bonds and other instruments in portfolios based on their ESG scores or categorically excluding securities, companies or certain sectors or industries as eligible securities based on specific ethical, religious, social or environmental guidelines or preferences. Traditional examples of exclusionary strategies cover the avoidance of any investments in companies fully or partially engaged in activities like gambling, sex-related industries, the production of alcohol, tobacco, firearms, fossil fuels, or even nuclear energy. These exclusionary categories have been extended in recent years to incorporate serious labor-related actions or penalties, compulsory or child labor, human rights violations, and genocide.  Screening can also extend to positive/best in class screening or norms-based screening in which issuers may be selected on the basis that they would outperform peers on specified ESG metrics or exceed a minimum ESG-rating threshold or excluded when issuers violate international standards such as the UN Global Compact, OECD Guidelines or ILO conventions.

Impact Investing: A relatively small but growing segment of sustainable investing, impact investments are directed to companies, organizations, and funds with the explicit intention to achieve measurable social and environmental impacts alongside a financial return. The direct capital in this strategy addresses challenges in sectors such as sustainable agriculture, renewable energy, conservation, microfinance, and affordable and accessible basic services, including housing, healthcare, and education.

Thematic Investing: An investment approach with a focus on a particular idea or unifying concept. Clean energy, clean technology, and gender diversity are a few of the leading sustainable investing fund themes. Investing in green, social, and sustainability bonds or low-carbon-emitting stocks, bonds, and funds also falls into the thematic investing category.

ESG Integration: This investment strategy involves the systematic, ongoing analysis of financially material environmental, social, and governance factors and risks. When deemed relevant and material to an entity’s long-term financial performance, these factors directly influence the buy, hold, and sell decisions of a security.  Within this category of sustainable investing, significant variations exist regarding how ESG integration is deployed in investment portfolios.  That said, no automatic restrictions on the investable universe are implied.    

Engagement/Proxy Voting: Employed either in conjunction with one of the above-mentioned categories or on a stand-alone basis, this approach leverages the power of stock ownership in publicly listed companies and, on a more limited basis, bond investments.  At one of the range, investors may seek information regarding a company’s strategies through direct corporate engagement and exercising proxy voting responsibilities.  But investors can exercise their ownership rights through action-oriented methods to influence corporate behavior, file shareholder proposals, and approach proxy voting in a more strategic manner.   While not owners, bond investors can also leverage their power of scale as investors, but their scope and leverage are more limited.  

It should be noted that these approaches are not mutually exclusive.  In practice, investors often blend several techniques. e.g., ESG integration plus thematic tilts plus active stewardship—to balance risk, return and real-world impact.

Navigating the Sustainable Investment Landscape: Key Insights for Informed Decisions

Sustainable investing may seem complex, but understanding its core drivers and benefits is straightforward. Firstly, it’s about aligning your investments with your values, moving beyond pure financial returns to consider broader societal and environmental impacts while also understanding and proactively accepting any trade-offs that may be involved. This values-driven approach fosters a more meaningful connection to your portfolio. Secondly, the increasing demand for sustainable products is driving significant innovation and growth in this sector, creating new opportunities for long-term investors. Finally, robust, sustainable research and analysis are crucial. It helps investors cut through the noise, identify investment opportunities, and avoid potential “greenwashing,” ensuring their investments genuinely align with their sustainability preferences and deliver on their expectations. Our independent analysis empowers you to make smarter, more sustainable choices.

Why offer research dedicated exclusively to sustainable investing?

The rapid expansion in the number of investors, investment managers, product offerings and assets under management and the continuing evolution of sustainable investing without the benefit of widely accepted sustainable investing frameworks, definitions, and rules, have contributed to confusion and misunderstanding regarding this sector of investing, the meaning of sustainable investing, and related to this, the financial and non-financial expectations or outcomes associated with sustainable investment product offerings. Affecting investors, regulators, managers, politicians, and other stakeholders, it has become increasingly difficult to differentiate between various funds and their sustainable strategies and outcomes. This makes it more challenging for investors and financial intermediaries to align investment products with sustainable goals, objectives, and values expressed by investors. As sustainable products continue to expand in number and investors, there is a growing risk that fund strategies might diverge from expectations (“greenwashing”) or may not align with investor beliefs or values and lead to disappointments or worse, in the form of redemptions and possibly litigation. The recent politicization of ESG is another manifestation of this issue.
