what are thematic ETFs?

Investing has evolved far beyond just picking individual stocks or broad market index funds. One of the most exciting developments in recent years has been the rise of thematic exchange-traded funds (ETFs). These funds allow investors to align their portfolios with long-term trends, disruptive innovations, and themes that reflect their personal beliefs about where the economy, technology, or society is headed.

understanding thematic ETFs

A thematic ETF is an exchange-traded fund that invests in companies tied to a specific theme or trend, rather than focusing on a region (e.g., Australian shares) or a broad sector (e.g., healthcare). These themes are often based on long-term structural changes in the economy or society.

For example, a thematic ETF might focus on:

• Clean energy (solar, wind, battery technology)
• Artificial intelligence and robotics
• Cybersecurity
• Aging populations and healthcare innovation
• Space exploration

Instead of holding a wide mix of unrelated companies, a thematic ETF narrows its scope to businesses directly connected to the chosen theme.

the Netflix way to think about it

You don't just watch one show. You click on "Sci-Fi & Fantasy" and get Stranger Things, Black Mirror, The Witcher, and a bunch of other titles that all fit the vibe. A thematic ETF does the same with investing. Instead of buying one company, it groups together a bunch of companies tied to the same trend. Buying a thematic ETF is like saying: "I don't just want one show, I want the whole category because I believe this theme is going to stay popular."

how thematic ETFs work

Like all ETFs, thematic ETFs are traded on stock exchanges just like individual stocks. Investors can buy and sell shares throughout the trading day, making them liquid and flexible.

The fund manager selects companies based on the theme, which could include:

• Pure-play companies are businesses that are primarily focused on the theme itself. Their main products, services, and revenue streams come directly from that trend.
• Supporting players are businesses that may not be fully centered on the theme but still benefit from it in important ways. They provide the tools, infrastructure, or complementary services that help the theme grow.

For example, the BetaShares Global Cybersecurity ETF (ASX: HACK) includes leading cybersecurity firms like CrowdStrike and Palo Alto Networks, but also exposure to broader tech providers that support secure digital ecosystems.

benefits of thematic ETFs

• Targeted Exposure: Investors can focus on specific areas they believe will grow in the future.
• Diversification Within a Theme: Unlike picking a single stock, thematic ETFs spread risk across multiple companies within the theme.
• Accessibility: They provide exposure to complex or niche sectors without requiring deep expertise.
• Alignment with Personal Values: Many investors like backing themes such as sustainability, innovation, or diversity.

risks to keep in mind

While thematic ETFs can be exciting, they come with unique risks:

• Concentration Risk: Because they zoom in on one theme, you don't get the same spread of companies that a broad index fund gives you.
• Volatility: New or fast-changing themes, like space exploration or streaming, can rise and fall in value very quickly.
• Hype Risk: Some themes get a lot of attention for a while but may not last in the long run.
• Higher Fees: Thematic ETFs often charge slightly more in fees than traditional ETFs.

thematic ETFs on the ASX

If you're investing in Australia, the good news is that thematic ETFs have grown significantly on the ASX over the past few years. You don't need a US brokerage account to get exposure to global trends.

Each of these trades on the ASX in Australian dollars during normal market hours. Management fees typically range from 0.47% to 0.69% per year, which is higher than a broad market ETF but reasonable for specialised exposure.

thematic vs broad index ETFs

Most Australian investors start with broad market ETFs like Vanguard Australian Shares (ASX: VAS) or BetaShares Australia 200 (ASX: A200). These give you a slice of the entire market in one trade. So where do thematic ETFs fit?

think of it like building a meal

A broad index fund is the base. Rice, pasta, whatever fills the plate. Thematic ETFs are the ingredients you add because you care about a specific flavour. You wouldn't build an entire diet around chilli flakes, but a bit goes a long way.

The key difference is time horizon. Broad index funds are designed to track the market over decades. Thematic ETFs are a bet on a specific trend playing out over the next 5-15 years. Sometimes that bet pays off enormously (clean energy post-Paris Agreement). Sometimes it takes longer than expected (hydrogen is still early). Knowing that going in helps you stay patient.

how to evaluate a thematic ETF

Not all thematic ETFs are built the same way. Before you invest, here are a few things worth checking:

• Clarity of theme: Is the theme well-defined and not overly broad? A fund called "future technology" could mean almost anything.
• Holdings quality: Are the underlying companies true innovators, or just tangentially related? Look at the top 10 holdings and see if they make sense for the theme.
• Geographic exposure: Some themes are more prominent outside Australia. EV supply chains run through Asia, cybersecurity is dominated by US firms, and green hydrogen has significant Australian exposure. Know where your money is going.
• Fund size and liquidity: Larger ETFs with higher trading volume tend to have tighter bid-ask spreads, meaning you pay less to get in and out. On the ASX, check daily trading volume before buying.
• Management fees: Compare costs across similar funds. A 0.20% difference might not sound like much, but over 10 years on a growing balance, it adds up.

who should consider thematic ETFs?

Thematic ETFs may suit investors who:

• Want to add growth potential through emerging trends.
• Have high conviction about certain industries or innovations.
• Are looking to complement a core portfolio of broad index funds with more targeted bets.

However, they may not be ideal as the foundation of a portfolio - rather, they work best as a satellite holding to add flavor and future-focused exposure.

how inaam uses thematic thinking

inaam builds on the same idea behind thematic ETFs, but starts from a different place. Instead of picking a theme from a list, you tell us what matters to you. Sustainability, healthcare access, ethical supply chains, renewable energy. We take those values and build a micro-portfolio around them, selecting the companies and funds that actually match.

The difference is that a thematic ETF gives you one theme per fund. inaam lets you combine multiple themes into a single portfolio that reflects all of your values at once, for $10 a month. You can see exactly what you own, why it's there, and what impact it's connected to.

If you've been reading about thematic ETFs and thinking "I want something like this but more personal," that's essentially what we built.

final thoughts

Thematic ETFs give everyday investors access to ideas that used to require specialist knowledge or large minimums. From clean energy on the ASX to global cybersecurity, you can back the trends you believe in with a single trade.

The important thing is understanding what you're buying and why. Themes go through cycles. Some will take off, others will take longer than expected. Keeping thematic positions as part of a broader portfolio, not the whole thing, helps you stay in the game long enough for the thesis to play out.
