The Guinness Sustainable Energy Fund gives investors exposure to global sustainable energy markets.

The Fund is managed for capital growth and invests in companies involved in the generation, storage, efficiency and consumption of sustainable energy sources (such as solar, wind, hydro, geothermal, biofuels and biomass). We believe that over the next twenty years the sustainable energy sector will benefit from the combined effects of:
  • Demand growth - renewable energy becoming competitive with power from fossil fuels
  • Improving Economics - alternative energy equities are undervalued due to poor energy sector sentiment, whilst fundamentals of renewables remain strong due to low cost of installation
  • Public & Private Support – corporate, consumer and government interest due to economics underpins long-term prospects
  • Low current exposure - alternative energy offers solutions to climate change, pollution, and energy security
  • Sustainability ThemeThe sustainable energy sector offers ‘green’ credentials that some investors are targeting to help facilitate global de-carbonisation and to reduce carbon intensity of their portfolios
Single sector Companies engaged in the generation and storage of sustainable energy and the electrification and efficiency of energy demand

In brief: why invest in sustainable energy?

Demand growth
The electrification of transportation and improved energy storage economics brings attractive long term sustainable energy demand growth
Improving Economics
Both governments and companies are pursuing sustainable energy in order to achieve mandated carbon targets or to improve public perception
Public & Private Support
Both governments and companies are pursuing sustainable energy in order to achieve mandated carbon targets or to improve public perception
Low current exposure
Poor profitability and need for subsidies has kept the weight of sustainable energy in global indices and broad global equity funds at a low level
Sustainability Theme
The sustainable energy sector offers ‘green’ credentials that some investors are targeting to help facilitate global de-carbonisation and to reduce carbon intensity of their portfolios

Investment process

Our stock selection is driven 50% by our top-down views and 50% by bottom-up stock analysis. The top-down views shape our energy sub-sector allocation, whilst bottom-up analysis is designed to identify the best stocks to populate our sub-sector allocation. The investment team applies a mixture of value and growth investing, with a bias towards value.

Top-down views

We conduct rigorous independent analysis of the fundamental drivers of sustainable energy markets: energy commodity prices; sustainable energy technology research and development; installation and equipment prices; political and economic support for the sector; government and private sector demand. This allows us to analyse likely demand for sustainable energy equipment and services and creates our top-down view, which in turn informs our industry energy sub-sector allocation. Analysis of the key drivers of growth, scarcity, barriers to entry and economics informs our weighting to our internally generated Sustainable Energy subsectors

Bottom-up stock screening

The team operates a disciplined stock screening process. We review a universe of around 179 sustainable energy stocks each week to identify companies which look attractive on their return on investment, valuation, earnings sentiment and price momentum. Other sub-sector specific screens are also employed to generate ideas.

Stock due diligence

Stock ideas are taken from our screens. We then conduct due diligence to establish whether we have conviction to include the stock in our portfolio. The due diligence centres around detailed financial modelling.

Portfolio construction

Equally-weighted portfolio

The portfolio comprises around 30 equally-weighted positions. Our equally-weighted portfolio construction is designed to create a balance between maintaining fund concentration and managing stock-specific risk. It also imposes a structural sell discipline: an existing position must be sold to purchase a new holding.

Sector weights

There is no benchmark adherence in the Fund’s sub-sector weights.

Portfolio risk controls

Stock specific risk

Stock specific risk in the sustainable energy sector tends to be higher than the broader market. By constructing the fund of 30 equally weighted positions, we avoid significant exposure to any one individual stock.

Emerging market exposure

There are no limits to emerging market exposure.


The portfolio is liquid, with 90% of the Fund normally invested in companies with a market capitalisation over US $500 million.


The Fund is not hedged from a currency perspective.
