ETFs have established themselves as one of the preferred tools for individual investors to gain exposure to the financial markets. Simple, transparent, and low-cost, they make it easy to invest in broad long-term trends without having to pick individual stocks yourself.
But with the proliferation of themes and indices available, one question remains: how to use ETFs intelligently to capture the major market dynamics in 2026 without unnecessarily complicating one’s portfolio? Explanations.
Why are ETFs particularly well suited for investing in 2026?
2026 is likely to be far from easy for investors. The geopolitical context remains tense, economic balances fragile, and many major decisions will play out as well in Europe as in the United States, not to mention the rest of the world. In other words, market readability is likely to be limited.
In this kind of environment, certain themes could logically stand out (for example the defense sector), but nothing is ever guaranteed. Markets can change direction quickly, and the risk of error is real when trying to identify “the right stock” at the right time.
It is precisely in this context that ETFs make all the sense. They offer a simpler way to invest in the stock market, notably because they allow:
- to reduce the risk associated with choosing a single company;
- to benefit from immediate diversification;
- to avoid stock picking when visibility is low.
Then comes the choice of ETF type, and two broad types of ETFs exist: index ETFs and thematic ETFs.
Index ETFs or thematic ETFs: how to make the right choices in 2026?
One of the main trade-offs investors face when looking at ETFs concerns the choice between index ETFs (broad exposure) and thematic ETFs (more targeted exposure).
There is no universal method, nor a solution better than another in absolute terms. It all depends primarily on the investor’s sensitivity, their level of conviction, and their way of approaching the markets.
If you have a strong conviction about a specific theme (for example an innovative technology or a structural shift in the economy), thematic ETFs naturally take precedence.
Conversely, when visibility is lower or you want to stay exposed to the markets without any specific anticipation, index ETFs offer a more global and reassuring approach.
To better understand the differences between these two approaches, here is a concise comparison between index ETFs and thematic ETFs.
Index ETFs vs Thematic ETFs: the main differences
| Criteria | Index ETFs | Thematic ETFs |
| Objective | Follow the overall performance of a market or a geographic region | Expose to a trend or a specific sector |
| Diversification | High, with a broad basket of values | More limited, focused on a theme (e.g. artificial intelligence) |
| Performance potential | Aligned with the market’s average performance | Potentially higher, but riskier |
| Volatility | Generally moderate | Often higher |
| Risk of getting it wrong | Relatively low over the long term | Greater if the theme underperforms |
| Readability | Very good, simple and understandable approach, national stock indices | Depends on understanding the theme (notably in themes like biotechnology) |
| Investment horizon | Longer-term | Medium to long term, with more regular monitoring |
| Role in a portfolio | Core pillar | Complement or “satellite” |
In practice, many investors choose to combine these two approaches: a base of index ETFs to capture the overall market trend, and a more targeted exposure via thematic ETFs to reflect certain personal convictions.
Marc’s comment:
However, one must remain cautious with thematic ETFs, as some trends may be more fashion-driven than a durable economic dynamic. A theme can massively attract investors at a given moment, benefit from strong media buzz, and then gradually disappoint when growth prospects do not materialize.
What are the major market trends to watch in 2026?
In a difficult, even worrying, economic and geopolitical environment, identifying major market trends is not about chasing the “miracle sector,” but about spotting underlying dynamics likely to endure over time.
In 2026, several axes continue to guide investment flows.
Technology and innovation
Technology and innovation remain central pillars of financial markets, particularly in the United States. American markets maintain a lead, driven by a mature tech ecosystem, massive investments, and a continually high capacity for innovation.
In 2026, this dominance is expected to translate into a significant contribution to the performance of U.S. stock markets.
Europe, for its part, has historically lagged behind in this area.
However, recent geopolitical tensions, notably with the United States and the positions taken by Donald Trump, have highlighted Europe’s technological fragilities.
This awareness is gradually changing the game. It could translate into accelerated investments in Europe, stronger support for local players, and, in the long term, the emergence of new opportunities on European soil.
For investors, exposing themselves to technology and innovation in 2026 can therefore follow two distinct logics:
- prioritize American markets, which dominate today and offer higher visibility;
- accept a higher risk in Europe, with the idea that this technological lag could become, in the medium term, a lever for catch-up and value creation.
Artificial intelligence and semiconductors
Artificial intelligence now stands as one of the main battlegrounds of technological competition among the major economic powers, led by the United States and China.
U.S. markets today enjoy a clear advantage, driven by well-established players, substantial investment capacity, and a particularly dynamic tech ecosystem. In 2026, this lead is expected to continue supporting the valuation of AI-related companies and digital infrastructure.
China, for its part, follows a different trajectory. The country pursues a long-term strategy aimed at reducing its technological dependence, notably in semiconductors. This desire for autonomy could, in the long run, open interesting prospects, even if visibility remains more limited than on the American markets.
For investors, exposure to artificial intelligence in 2026 means weighing between:
- the strength and depth of the American market, which remains the reference today;
- the catch-up potential of China, with possible opportunities but also a higher level of risk.
Marc’s comment:
AI potentially belongs to those trends that generate very rapid enthusiasm, then disappoint when expectations become excessive. Many experts today warn about the risk of an AI speculative bubble, fueled by sometimes too-high expectations. This does not challenge the long-term potential of artificial intelligence, but calls for caution in the short term.
Global growth via major international stock indices
Rather than multiplying sector investments, many investors choose in 2026 to gain direct exposure to world growth via major international indices (e.g., MSCI World). This approach aims to capture broad economic dynamics without trying to forecast precisely which sectors or companies will outperform.
ETFs linked to broad stock indices thus allow:
- to track the evolution of developed and global economies,
- to automatically incorporate the best-performing companies over time,
- to benefit from broad geographic and sector diversification.
Marc’s comment:
However, one should keep in mind that even so-called “global” ETFs, such as those tracking the MSCI World, remain heavily exposed to the U.S. market, often at more than 60%.
How to invest in ETFs in 2026 in practice?
For many investors, the main obstacle to ETF investment remains perceived complexity: too many choices, too many decisions to make, and the fear of getting the timing right to start.
In 2026, solutions like Plum are precisely aiming to remove these obstacles.
The fintech Plum offers a simple and progressive approach to ETF investing, with a selection of about 40 ETFs covering major geographic regions and key market trends. The goal is not to multiply arbitrage opportunities, but to facilitate regular exposure to financial markets.
The Plum app focuses in particular on automation: scheduled investments, rounding up daily expenses, or personalized savings rules. This approach lets you invest without constantly thinking about it, while smoothing entry points into the markets.
In an uncertain environment like 2026, this logic can prove relevant: it helps the investor stay disciplined, avoid emotional decisions, and gradually expose themselves to long-term trends without trying to anticipate every market move.
