Thematic ETFs: Zeroing In on Trends and Values

Key Points

  • Thematic ETFs offer targeted exposure to specific trends.
  • They allow you to align your portfolio with your outlook and values.
  • Investment goals can be balanced with the theme and your risk tolerance.
  • Example thematic ETFs include the technology, ESG, healthcare, blockchain, and clean energy sectors.

Long-term investing is boring. It should be boring, too. Growing wealth is a marathon, and the best way to succeed in the market is to sit on your hands, letting your well-diversified portfolio marinate for as long as you can.

But. We also understand the allure of chasing the Next Big Thing. Or the compulsion to put your money to work making the world a better place.

So, why thematic ETFs? It’s simple: they resonate with the investor who wants a bit more control, a bit more specificity, maybe a bit more excitement. They cater to those who aren’t just looking to ride the market’s broad waves but are keen on surfing the more nuanced ripples of individual sectors or themes. They can help scratch that itch to be more involved with your portfolio.

Understanding Core and Satellite Investing

Core and satellite investing is a strategic approach that balances stability and growth in an investment portfolio. At its heart lies the ‘core’, typically consisting of global equity and bond ETFs. These core investments form the foundation, offering broad market exposure and a cushion against market volatility. They’re chosen for their reliability and potential to deliver consistent returns over the long term.

Surrounding this core are the ‘satellites’ – specialised investments like thematic ETFs. These satellites provide the opportunity to jump on specific trends, sectors, or investment ideas, such as technological innovations or environmental sustainability. While they carry higher risk and volatility, they also offer the potential for higher returns, making them an excellent complement to the more stable core investments.

This approach marries the best of both worlds: the security of global equities and bonds with the dynamic growth potential of thematic ETFs. It’s a strategy that allows investors to stay rooted in the fundamentals while reaching for the stars in specific areas of interest or growth.

The Appeal of Thematic ETFs as Satellites

Thematic ETFs allow you to target specific market niches and trends that you feel strongly about, or that align with your values. As satellite components in a core and satellite strategy, these ETFs offer several compelling advantages:

Targeted Exposure to Emerging Trends: Thematic ETFs allow investors to tap into emerging or disruptive trends like artificial intelligence, renewable energy, or healthcare innovation. This targeted exposure can potentially lead to significant gains, especially if these sectors outperform the broader market.

Enhanced Portfolio Diversification: While the core holdings in global equity and bond ETFs provide broad market exposure, thematic ETFs add another layer of diversification. By investing in specific themes, investors can reduce the risk of their portfolio being overly concentrated in one sector or geography.

Flexibility and Responsiveness: Thematic ETFs offer the flexibility to quickly capitalise on evolving market trends. Investors can adjust their satellite holdings to respond to new developments or shifts in market dynamics, keeping the portfolio aligned with the latest investment opportunities.

Alignment with Personal Interests and Values: Many thematic ETFs focus on areas like sustainability, social responsibility, or specific technological advancements. This allows investors to align their portfolios with personal values or interests, adding a meaningful dimension to their investment choices.

Potential for Higher Returns: While they come with higher risks, thematic ETFs often have the potential for higher returns, especially if the selected theme experiences rapid growth. For investors with a solid core portfolio, these higher-risk investments can provide an opportunity to boost overall portfolio performance.

Scratching the Active Investment Itch: For those who desire to be more hands-on with their investments, thematic ETFs offer a way to actively engage with specific market trends, beyond the more passive core portfolio.

Incorporating thematic ETFs as satellites in a core and satellite investment strategy allows you to maintain a stable base while exploring opportunities in specific areas of the market. This balance of stability and targeted growth can be an good way to build a robust, diversified portfolio.

Selecting the Right Thematic ETFs

Choosing the right thematic ETFs to complement your core portfolio of global equity and bond ETFs is ultimately a personal choice. Here are some of the things you should consider when selecting thematic ETFs as satellite investments:

Alignment with Investment Goals: Assess how a thematic ETF fits with your overall investment objectives. Whether you’re seeking long-term growth, jumping on specific trends, or aligning with personal values, ensure the ETF’s focus aligns with these goals.

Understanding the Theme: Whether it’s technology, clean energy, healthcare innovation, or another niche, having a solid grasp of the sector’s potential and risks is essential. Research the driving forces behind the theme and its long-term viability.

Performance History and Fund Management: Examine the ETF’s track record and the approach of its management team. While past performance is not indicative of future results, it can provide insights into how the ETF has navigated market ups and downs. As ever, look for passive funds that track an index as they will almost certainly outperform actively managed funds.

Costs and Fees: Thematic ETFs can have higher expense ratios compared to traditional ETFs. Understand the fee structure, including management fees and transaction costs, as these can impact overall returns.

Liquidity and Size: Consider the ETF’s liquidity and assets under management. Highly liquid ETFs are easier to trade, especially in volatile markets. The size of the fund can also be a factor, as very small or new funds might carry additional risks.

Diversification within the Theme: Look at the ETF’s holdings to ensure it’s not overly concentrated in a few stocks. A well-diversified thematic ETF can mitigate risk while still providing focused exposure to the theme.

Market Trends and Timing: By all means stay informed about current market trends and consider the timing of your investment. Remember though that timing the market is almost impossible, and a better strategy is to take a long-term view of where you think the sector is headed.

By carefully selecting thematic ETFs that complement your core global equity and bond holdings, you can enhance your portfolio’s potential without straying from your overall investment strategy. Think about what’s important to you, or the direction you think the winds of history are blowing.

This is just a small selection of what is available. It’s important to conduct thorough research and consider the fit of these thematic ETFs with your core portfolio. The goal is to ensure these satellites add value, diversification, and growth potential without disproportionately increasing risk.

Integrating Thematic ETFs with Your Core Portfolio

Successfully integrating thematic ETFs into a core and satellite strategy requires a thoughtful approach. Here’s how you can blend these dynamic investments with your core global equity and bond ETFs:

Assess Your Current Portfolio Composition: Before adding any thematic ETFs, evaluate your existing portfolio. Understand the weightage of your core global equity and bond ETFs, and determine how much of your portfolio you’re comfortable allocating to higher-risk thematic investments.

Determine the Allocation to Thematic ETFs: Satellites should form a smaller portion of your portfolio compared to the core. Decide on the percentage of your total investment you want to allocate to thematic ETFs, keeping in mind your risk tolerance and investment horizon.

Choose Complementary Themes: Select thematic ETFs that complement rather than overlap with your core investments. For instance, if your core portfolio lacks exposure to a particular sector like healthcare or a specific geographic region, a thematic ETF in that area can fill the gap. It’s worth bearing in mind that global equity ETFs are already heavy on technology stocks.

Diversify Across Multiple Themes: Rather than concentrating on a single thematic ETF, consider diversifying across different themes. This reduces the risk associated with any one sector or trend underperforming.

Monitor and Rebalance Regularly: Thematic investments can be more volatile than core holdings. Annual rebalancing is a good idea to ensure that your thematic ETFs don’t get out of proportion with the rest of your portfolio.

Stay Informed and Flexible: The appeal of thematic ETFs lies in their ability to capitalise on emerging trends. Staying informed, but try to take the long view where possible. It’s also OK to have fun with this part of your portfolio – the core is there to stop you gambling away your retirement.

Integrating thematic ETFs into your investment strategy can add a dynamic element to your portfolio, offering both diversification and the potential for enhanced returns. They also allow you to get involved in sectors you believe are important.

Risks and Considerations in Thematic ETF Investing

While thematic ETFs can be a valuable addition to a core and satellite investment strategy, you need to be aware of the risks and considerations associated with these types of investments:

Market Volatility and Concentration Risk

Thematic ETFs often focus on specific sectors or trends, which can lead to higher volatility and concentration risk. If a particular theme or sector experiences a downturn, it can significantly impact the ETF’s performance. Stay small and nimble.

Timing and Trend Longevity

The success of thematic ETFs often depends on getting the timing right. Investing too early or too late in a trend can affect returns. Additionally, some themes may be short-lived or may not develop as expected, leading to underperformance. Timing the market is a fool’s errand – take a long view.

Liquidity Concerns

Some thematic ETFs, especially those targeting niche sectors, may have lower trading volumes, leading to liquidity concerns. This can make it challenging to buy or sell shares when you need to. Stick to the bigger funds.

Research and Due Diligence

Thematic investing requires more research and due diligence compared to more traditional investments. Investors need to thoroughly understand the theme, the ETF’s holdings, and the factors that can influence its performance.

Costs and Expense Ratios

Thematic ETFs can have higher expense ratios than more traditional ETFs. Higher fees can eat into returns, so it’s important to weigh the potential benefits of the investment against its costs.

Diversification Limits

While thematic ETFs can add diversification to a portfolio, they should not be relied upon as the sole means of diversification. Balancing them with broader, more diversified investments is crucial to maintaining a well-rounded portfolio.


It’s essential to balance the pursuit of higher returns with a clear understanding of the potential risks involved in thematic investing. On the other hand, if you are investing based on your values, a lower return may be an acceptable price to pay for knowing your money is working for the good of the planet.

It’s also OK to see your satellite investments as an entertainment expense. Your core portfolio is there to cushion your long-term wealth against dodgy bets. Just make sure your satellite fund is small enough not to cause you anguish if it goes belly-up.
