Overview
On 1st January 2025, the Guinness Sustainable Global Equity Fund was renamed to the Guinness Global Quality Mid Cap Fund to better reflect its investment philosophy - the Shareholder notice is available here.
The Guinness Global Quality Mid Cap Fund provides investors with exposure to a diversified portfolio of mid-cap companies from around the world. The Fund focuses on businesses that are consistently profitable and exposed to structural growth themes within the sustainability space, delivering potential for long-term capital growth. Actively managed and benchmarked against the MSCI World Mid Cap Index for performance comparison, the Fund maintains a high-conviction portfolio of quality equities across developed markets.
We believe that companies that can maintain a high return on capital as they grow, will outperform.
- By accessing businesses exposed to or enabling structural growth themes within the sustainability space, we avoid story stocks, focusing instead on businesses with underlying demand drivers.
- Mid Cap businesses are frequently overlooked despite exhibiting long-term outperformance with better risk-adjusted returns versus their large and small cap counterparts.
We maintain a high-conviction portfolio of around 30 equally-weighted stocks, with low turnover and no benchmark-driven constraints on sector or regional weightings
Investment Team
High quality funds are run by high quality people.
We are proud of our collegial culture, with teams across the business benefiting from each other’s expertise as they target long-term returns for investors.
How to Invest
We aim to make it simple to invest in our funds. All our funds are open to direct investment via an application form. They are widely available on investment platforms and are eligible for UK investors’ ISAs and SIPPs.

Investment Case
The Fund is designed to provide investors with exposure to quality mid cap equities exposed to structural growth themes within the sustainable space. We believe this provides investors with a differentiated exposure to future leaders with growth driven by long-term demand drivers such as improved health and wellbeing, resource management, and innovative technologies.
Why Invest in the Guinness Global Quality Mid Cap Fund?
Quality-first approach
We believe that companies that can maintain a high return on capital as they grow will outperform. We aim to identify companies that generate persistently high returns on capital, ensuring a focus on quality businesses capable of compounding shareholder value without using excessive debt.
Mid cap focus
Mid cap companies occupy a unique position in the investment landscape, combining the resilience of established businesses with the dynamism of growth-oriented firms. These companies are often under-researched and underutilised by investors – no more so than today with the overconcentration of indices and funds in a narrow set of mega-cap businesses. We believe mid caps represent a “sweet spot” for equity investing.
Structural growth within the sustainable space
In order to find companies capable of outgrowing the broader market, we seek companies exposed to structural growth themes within the sustainability space such as improved health and wellbeing, resource management, and innovative technologies. These areas have long-term demand drivers driven by changing consumer preferences, social norms and changing government regulations.
High conviction
The Fund usually invests in just 30 companies, with each company having a broadly equal weighting. This provides a good balance between the benefits of diversification while allowing each company to add meaningfully to performance. We do not have a long tail of small positions and by definition we can never just 'hug' the benchmark index.
How do we run the Fund?
Quality Screen
Our starting point in selecting our investment universe is to identify companies with persistently high or improving return on capital. Specifically, we look for two separate – but not distinct – groups of companies:
- Established compounders that have a return on capital of greater than 10% in each of the previous ten years.
- Emerging compounders that have a return on capital of greater than 10% in each of the previous 5 years with that return on capital growing across the previous 5-year period.
Our analysis shows that established and emerging compounders are highly likely to continue generating persistently high return on capital in the future. Consequently, it shows emerging compounders are highly likely to turn into established compounders in the future. Together, they show that these businesses will continue to create shareholder value.
“It's a rare achievement for a company to meet our investment criteria and we think it shows a mark of genuine quality. And this is where our portfolio starts – consistent high return on capital.”
On average, only 5% of global listed companies achieve our threshold. We then exclude highly leveraged businesses (net debt/EBITDA > 3), leaving a pool of around 650 companies.
Negative Screening
We find that companies exhibiting quality characteristics, as described above, positively correlate with better ESG scores, using MSCI ESG research methodology. Hence, we find that by first screening for high quality businesses, we indirectly exclude many businesses that have been deemed to have below average or inadequate management of ESG issues.
However, this alone does not mean we end up with a pool of companies automatically deemed sustainable. In order to further increase our chances of finding these companies, we apply exclusionary screens to filter out companies whose products or services are harmful, and whose ESG practices are sub-standard. Namely we exclude companies which derive more than 10% of revenue from:
- Alcohol
- Fossil fuels
- Gambling
- Nuclear energy
- Palm oil
- Tobacco
- Weapons
- Adult entertainment
We also exclude those companies on the Norwegian Council of Ethics exclusion list. Such businesses tend to display inadequate or worsening management of ESG issues and are vulnerable to ESG related disruptions and controversies.
Identifying Mid Caps
Mid cap companies occupy a unique position in the investment landscape, combining the resilience of established businesses with the dynamism of growth-oriented firms. These companies are often under-researched and underutilised by investors – no more so than today with the overconcentration of indices and funds in a narrow set of mega-cap businesses. We believe mid caps represent a “sweet spot” for equity investing.
Mid caps have outperformed both their large and small cap counterparts over 25 years (MSCI indices) by growing their earnings and revenues faster – and with a better return/risk ratio.
The above screens leave the investible universe with around 500 companies from which to seek our 30 best ideas for the portfolio.
Mid cap companies are defined as companies having market capitalisations between the smallest and largest market capitalisations of companies included in the MSCI World Mid Cap Index. The Fund intends that the companies whose equity securities are held by the Fund will meet this definition when initially purchased by the Fund.
Stock selection
From this universe, we then seek to identify which companies are the most attractive long-term investment propositions. We apply screening and utilise scorecards based on quality, growth, and valuation to prioritise candidates for extended due diligence.
Fundamentally, we seek businesses capable of outgrowing the broader market. In addition to seeking growth through a mid cap lens, we also seek companies exposed to structural growth themes within the sustainable space as these areas have long-term demand drivers driven by changing consumer preferences, social norms, and changing government regulations.
To do so, we look for companies with the majority of the business activity exposed to at least one of the following themes:
- Health
- Wellbeing
- Safety & Security
- Cleaner Energy
- Resource Management
- Innovative Technologies
Above all, we want to understand what competitive advantages or barriers to entry are sustaining a company’s return on investment to determine whether the returns will persist. We also recognise that sentiment and hype can sometimes drive up the valuations of sustainable companies and so we try to maintain a strict value discipline. We want to avoid paying up for high levels of expected growth in the future, and therefore use a variety of valuation tools including looking at valuations vs sectors, peers and the company’s history, as well as looking at the quality and growth metrics baked into a company’s valuation relative to alternatives.
Sell discipline
It is often easier to find companies to buy that look cheap than it is to identify those companies you own which should be sold. We consider sell discipline as important as selecting companies for purchase and continuously monitor the companies we hold in the Fund. The six core reasons we may sell a company are outlined below.
- The company no longer qualifies as sustainable
- The company now derives a material portion of revenue from harmful products
- The company’s ESG practices have deteriorated materially - The balance sheet becomes stretched
- The valuation becomes too rich, or no longer offers compelling upside
- There is a change in a company’s capital budgeting approach
- Our original investment thesis no longer holds
- We find a more compelling investment idea
How do we construct the portfolio?
The Guinness Global Quality Mid Cap Fund is a concentrated portfolio of around 30 broadly equally weighted stocks. This provides a number of useful attributes:
- It reduces stock-specific risk, as we will not be overweight in a small number of favourite companies.
- We will not have a long tail of small holdings in the portfolio, which can be a distraction and a potential drag on performance.
- It instils a strong sell discipline as we must typically sell a position in order to make way for a new one; and we must constantly assess the companies we own in the portfolio in comparison to the rest of the universe available to us.
- We are truly index independent. All companies held are given equal target weights without regard to their weighting in the benchmark index, so our portfolio has a high active share.

Guinness Global Quality Mid Cap Fund is an equity fund. Investors should be willing and able to assume the risks of equity investing. The value of an investment and the income from it can fall as well as rise as a result of market and currency movement; you may not get back the amount originally invested. For full information on the risks, please refer to the Prospectus, Supplement, and KID/KIID for the Fund, which are available on our website (guinnessgi.com/literature). If you decide to invest, you will be buying units/shares in the Fund and will not be investing directly in the underlying assets of the Fund. Past performance does not predict future returns.
Source: FE fundinfo. Net of fees. Investors should note that fees and expenses are charged to the capital of the Fund. This reduces the return on your investment by an amount equivalent to the Ongoing Charges Figure (OCF). The current OCF for the share class used for the fund performance returns is 0.89%. Returns for share classes with a different OCF will vary accordingly. Transaction costs also apply and are incurred when a fund buys or sells holdings. The performance returns do not reflect any initial charge; any such charge will also reduce the return.
