Although thematic funds have been around for many decades, passive exposure via ETFs is a more recent development. A wide variety of thematic ETFs are now available but, with so much choice, how can you identify those with the greatest potential? It’s important for investors to understand what a thematic ETF aims to achieve, how to include them in a diversified portfolio, and be able to distinguish between genuine long-term investment opportunities and what may simply be interesting ideas based largely on hype and hope.
An evolution of sector ETFs
Thematics are an intelligent evolution of the traditional sector approach and can be used strategically or tactically in much the same way as sector ETFs. As an investor, you can expect thematic ETFs to have lower correlation with – and more short-term volatility – than broader equity exposures, and so it’s sensible to expect the potential for greater returns than broad equities over the longer term. That risk-return trade-off can be beneficial for diversification.
The biggest difference between thematic and sector ETFs is that sector ETFs group companies together by specific fields of business activity, while thematic ETFs seek to identify companies that are involved in a specific theme or global trend irrespective of their economic sector. A theme is often associated with disruptive technologies, such as clean energy, blockchain, robotics or other technological innovations.
When considering any theme, some of the questions an investor might want to ask include:
- Are there sustainable long-term growth drivers?
- Are there meaningful sources of demand?
- Is there a sufficient breadth of companies involved?
- Can the companies involved be measurably identified?
- Is the theme economically beneficial for companies involved?
- Where is the theme in terms of its evolution?
The rise of thematic ETFs
Thematic investments were once almost exclusively the domain of actively managed funds, but increased investor demand saw passively managed ETFs tracking new thematic indices gain popularity. There are now more than 200 thematic ETFs available in Europe with combined assets of more than $50 billion1. These thematic indices were typically created by specialist firms, sometimes in consultation with an ETF manager to ensure the index satisfied investor needs.
As this segment of the ETF industry grew, larger index houses either developed in-house capabilities or acquired these specialist firms. Today, many of the thematic ETFs in Europe follow indices that are constructed by the specialist arm of a large index house, which provides both expertise in the subject matter and a long robust history in the administration of indices.
Artificial intelligence as a technological innovation
Artificial intelligence (AI) has already made an important contribution to investing, including in the construction of thematic ETFs. Because these ETFs follow indices designed to select stocks based on characteristics other than sector classification, an index provider needs an efficient way to screen the universe of stocks for those meeting the theme’s definition.
Natural language processing (NLP), machine learning (ML) and other sophisticated AI technologies can be used to quickly and objectively search through thousands or potentially millions of corporate documents and communications to flag occurrences of relevant key words and phrases to identify potential candidates for inclusion in that theme.
The use of these technologies offers a powerful complement to more traditional subject-matter-led approaches to identifying thematic exposures and some strategies look to combine both.
Artificial intelligence as a thematic investment opportunity
The use of AI in index construction is just one example of the potential for the technology. Experts expect there to be examples of companies in most industries incorporating some form of AI into their products, services and business activities. This enormous growth potential makes AI a good case study for what makes a good theme from an investment perspective.
AI-enabled applications are predicted to contribute potentially US$15.7 trillion to the global economy by 20302. The largest part of this market is expected to be NLP followed by ML, with other potential growth areas including AI-enabled robotics and automation, and generative AI. Demand is being driven by the desire for greater efficiency and productivity from data-intensive devices that are such a critical part of our daily lives.
The concepts underpinning today’s AI date back to at least the 1950s, when scientists, mathematicians and even the Hollywood industry envisioned the potential for machines to formulate ideas. However, AI began taking shape in the ‘90s and has gathered pace more recently with more scalable applications. NVIDIA dominates the specialist chip market that is fundamental to the growth in AI-enabled applications, but the broader AI space includes more than enough diversity to construct indices, from broad to more specifically focused exposures.
Cyber Security and Defence Innovation
Cyber Security is a theme growing in importance, partly due to the success of AI. Cyber crime is one of the most advanced threats that anyone connected to the internet faces today and is predicted to cost US$12 trillion by 20253. The rising threat is due to more sophisticated cyber criminals using AI to make their attack more convincing through deepfake and other tactics. Companies that make the internet and mobile communications more secure should be in high demand, with growing sources of revenue, for decades to come.
The defence industry, unfortunately, is also seeing growing demand as threats intensify around the world. Technological innovation is reshaping defence strategies, with unmanned drones reducing the need for soldiers to be in harm’s way on the front line. Other innovations will hopefully act as deterrents for future conflict and, in so doing, make the world safer.
