In our recent survey of professional investors in Europe1, around 25% of all respondents said that passive strategies don’t provide expert stock selection. While it is true that many passive strategies are designed to give investors a pure beta exposure to known benchmarks like the MSCI World or the S&P 500, passive vehicles have immense scope to adopt a smart approach where it makes sense.

Thematic investing is one such area. Investing in megatrends is all about having a vision for the future and putting money behind things that will change the world. In such a space, adopting a beta approach does not work as it is tantamount to looking backwards rather than focusing on what lies ahead. At WisdomTree, we believe that expert stock selection in passive exchange-traded funds (ETFs) can be immensely valuable for investors.

Different themes require different approaches

Certain rules can be applied universally. When building products you can mandate broadly similar filters across themes on things like stock liquidity, market capitalisation, and basic ESG2. But stock selection itself, from defining a universe of eligible companies to picking and weighting the stocks, requires a bespoke approach which makes sense for the given theme.

At WisdomTree, we partner with industry experts with domain knowledge and experience in the theme under consideration. For example, in artificial intelligence (AI), our partnership with the Consumer Technology Association (CTA) helped us identify the AI value chain and the relative importance of the various components within it. We define the AI value chain as engagers – companies whose focus is in providing AI-powered products and services, enablers – companies who are key players in this space, with some of their core products and services enabling AI, and enhancers – companies who are a prominent force in AI but whose relevant product or service is not currently a core part of their revenue.

This approach is in stark contrast with how we view the automotive theme with our two partners Berylls and LeanVal. To capture trends of connectivity, autonomous driving, shared mobility, and electrification, we look to capture the 5 key categories of global automotive innovators. This includes suppliers, original equipment manufacturers, dealers and aftermarkets, mobility service providers, and infrastructure.

Approaching each theme differently in partnership with experts who fully understand the space helps us build strategies which give exposures that are representative of the underlying megatrend.

Informed view of the world

In our monthly report on the European thematic universe, we highlight how performance does not only vary among themes, but also differs significantly among funds within themes. We know there are no guaranteed recipes for success in investing. It can’t be said that an expert-led approach will always result in the best possible returns. However, we certainly claim that having expertise embedded within a product allows investors to make informed decisions.

For example, our Cybersecurity strategy developed in partnership with Team8 seeks to capture 8 different sub-themes. These include data security, cloud security, shift-left, smarter security, security of things, perimeterless world, resilience & recovery, and layer 8.

In contrast, our Renewable Energy strategy developed in partnership with Wood Mackenzie adopts an altogether different approach by conceptualising the idea of the renewable energy value chain. This comprises of 32 different subsectors within 5 major categories – raw materials, manufacturing, applications, enablers, and emerging technologies.

Experts guide investors on the best ways to represent and capture the theme. Incorporating expertise into strategies enables us to build thematic solutions that have a low overlap with major equity benchmarks but also among the different themes.

Evolving the theme over time

We know that in thematic investing the only constant is change. So how can investors ensure that their thematic investments evolve as the theme advances? Again, we believe an expert-led approach can help deliver a promising solution to this challenge.

Our Battery Solutions strategy, also developed in partnership with Wood Mackenzie, implements the idea of the intensity rating for each company in the battery universe when selecting stocks. The intensity rating calculation is illustrated in the figure below.

Each of the 37 different subsectors in the battery solutions strategy is evaluated at each rebalance every six months. The evaluation of the subsector and how much revenue the company generates from each subsector determines the company’s intensity rating which, in turn, influences the company’s selection and weighting.

Battery technology is a rapidly evolving theme. A lot can change in six months in terms of the relative attractiveness of different technologies. Having a forward-looking, bottom-up approach to evaluating the space allows the strategy to evolve with the broader theme over time. This is completely different to an approach that might use market capitalisation as a metric for selecting and weighting stocks.

Conclusion

The 25% of survey respondents who said that passive strategies don’t provide expert stock selection are almost right. Most strategies do not. But at WisdomTree, we have designed an approach that embeds expertise into thematic strategies giving investors a potential way to not only suitably capture the state of different megatrends today, but also better position themselves with an informed view of where the megatrend is headed.
