In the Fund Check series, fund managers of selected funds look back on developments over the past year and give their assessment of what we can expect in 2026. (Note: Prognoses are not a reliable indicator of future performance. Please note that investing in securities involves risks as well as opportunities.)

Summary

  • The fund performed well in 2025. However, this performance was accompanied by very high volatility, which was mainly due to political factors, particularly in the United States.
  • As in previous years, the focus remained on the energy sector, which in our case includes renewable energy such as wind and solar power, as well as batteries and geothermal energy.
  • After years of stagnation, we can see a sharp rise in electricity demand for the first time in 25 years. This is mainly due to data centres and AI (artificial intelligence), which are driving investment in infrastructure.
  • In the fund, we are therefore focusing on infrastructure providers, whether in the energy sector or in the field of energy efficiency.

Commentary by fund managers
Clemens Klein and Alexander Weiss

How did the fund perform in 2025?

The fund performed well in 2025. However, this performance was accompanied by very high volatility, which was mainly driven by political factors, particularly in the United States. Here, it was Trump's budget bill and flagship project, the One Big Beautiful Bill (OBBB) – which, with various drafts and amendments, led to significant fluctuations in our segment. Ultimately though, the final bill was better than the market had expected, and our fund has since outperformed the broader market. Although the tone and rhetoric from the White House will remain negative, the legal situation continues to be supportive for renewable energies such as wind and solar.

What were the fund’s main areas of focus in 2025?

As in previous years, the focus remained on the energy sector, which in our case includes renewable energy such as wind and solar, but also batteries and geothermal energy. After years of stagnation, we can see a sharp rise in electricity demand for the first time in 25 years, particularly in the United States. This is mainly due to data centres and AI (artificial intelligence), which are driving investment in infrastructure. Hyperscalers and the Magnificent 7 in particular are investing enormous sums in the expansion of these data centres – and in addition to the race for chips, the energy bottleneck is increasingly being cited as an important factor for further expansion. Accordingly, strenuous efforts are being made to bring as much electricity as possible onto the grid. Wind and solar are currently not only the cheapest sources of energy but can also be brought onto the grid the fastest. It is precisely this speed that is a strong argument for tech companies to rely on solar and wind energy – the price is often secondary.

 

What are the expectations of your fund management team with regard to global economic development and trends, among other things, for 2026?

The themes in the fund will remain unchanged. The biggest risk for the fund, as for the market as a whole, is a setback of the AI theme. In the fund, we are focusing on infrastructure providers, both in the energy sector (HASI, First Solar, Nextracker, etc.) and in the energy efficiency sector (Schneider Electric, ABB, Legrand, etc.). We are therefore investing more in the “shovel” part of the gold rush and are less dependent on which model or company ultimately prevails. Mark Zuckerberg recently said in a podcast, “If we end up misspending a couple of hundred billion dollars, I think that that is going to be very unfortunate, obviously. But what I'd say is I actually think the risk is higher on the other side.” This illustrates very well that no company wants to fall behind in the race for AI – and accordingly, we also see infrastructure investments as a longer-term driver.

What are your priorities in the fund, based on your expectations?

We continue to place a high emphasis on energy, and the USA remains an important market segment. Most AI innovation is currently taking place in the United States, which is also where the largest investments in data centres are being made. In addition, the legal situation has been clarified and is very supportive of renewables. Meeting energy needs is more important than ideological views. China is still not represented in either fund – most companies operating in our segment in China tend to work with very thin margins and are exposed to fierce (local and international) competition. Currently, the segments are weighted as follows: energy 64%, water 10%, recycling 10%, transformation 14%, and adaptation 2%.
