Last week, I decided to reduce the size of some positions in my portfolio in order to invest more in the current AI boom.

This involved 35 $BRK.B (+0,02 %) and 350 $SHEL (-0,37 %) shares were sold from my portfolio.

The following additions were made:

• $SIVE (+9,36 %) 1,500
• $AAOI (+1 %) 50
• $XFAB (+15,67 %) 400
• $SHT B (-0,58 %) 750

I didn’t quite time the entries perfectly in some cases, but let’s see what happens over the next few months and in 2027/2028. I’m curious to see how it goes.

In addition, the following stocks are on my shortlist for future purchases:

• $NOKIA (+5 %)
• 
  $LPK (+16,33 %)
• 
  $AXTI (+5,29 %)
• 
  $MRVL (+10,34 %)

Have a nice evening, everyone!

Probably not. Perhaps a European photonics cluster. When people talk about AI, it’s usually about NVIDIA, data centers, or the next language models. At the same time, something exciting has happened in Europe: In the planned Chips Act 2.0 , photonics has been explicitly named for the first time as a strategic field of the future.

This comes as no surprise. After all, modern AI systems need more than just computing power. Above all, they must process ever-larger amounts of data quickly, reliably, and energy-efficiently. This is precisely where a future infrastructure bottleneck could emerge.

What I find exciting is that (with the exception of X-Fab and Nokia) my own portfolio and, to some extent, the bottleneck wikifolios already include several European companies that together almost form a complete photonics value chain :

🇫🇷 Riber
$ALRIB (+8,7 %)

MBE systems for the production of highly specialized III-V semiconductors.

🇫🇷 Soitec
$SOI (+9,06 %)

Specialty substrates and wafer technologies as the foundation for photonic integration.

🇩🇪 Aixtron
$AIXA (+6,11 %)

Production equipment for InP, GaN, and other photonics applications.

🇳🇱 X-Fab
$XFAB (+15,67 %)

European foundry expertise for sensor technology and photonic applications.

🇸🇪 Sivers Semiconductors
$SIVE (+9,36 %)

Photonics and high-frequency chips for data transmission.

🇮🇹 Technoprobe
$TPRO (+6,54 %)

Probe cards and test solutions for increasingly complex semiconductor structures.

🇫🇮 Nokia
$NOKIA (+5 %)

Optical networking technologies for the next generation of data transmission. The acquisition of Infinera makes Nokia an increasingly relevant European player in the field of optical networking.

🇮🇹 Prysmian
$PRY (+7,95 %)

Fiber-optic infrastructure as the physical backbone of digital data transmission.

Taken individually, some of these companies seem rather unremarkable. Taken together, however, they tell a different story. Not that of a continent that has fallen behind. But rather the story of a potential European photonics ecosystem in the making.

Whether this will actually give rise to global champions, no one knows today. But that is exactly where I look for bottlenecks: one level below the obvious winners. Where new technologies are made possible in the first place.

⚠️ Not investment advice.

Thanks to our Donald 🍊, I took a look at which European stocks could follow the current hot American stocks. While tech giants in the USA are often valued at the limit, the European "backyard" offers massive catch-up potential - driven by the need for technological sovereignty.

Two stocks in particular caught my eye: $AAC (+2,43 %)
(AAC Clyde Space) and $XFAB (+15,67 %)
(X-FAB Silicon Foundries). Both are still quite small compared to their US peers, but they set a decisive course in January 2026.

- AAC Clyde Space (AAC): Just a few days ago (12.01.2026), the green light was given for the 60 million euro "EPS-Sterna" project. With the new anchor shareholder Bonnier Capital the financing is finally in the bag until the 2026 break-even point. 🚀

- X-FAB (XFAB): While Trump is ramping up tariffs on chips in the USA, X-FAB has just (January 2026) received massive EU subsidies for the plant in Erfurt. The valuation is attractive with a P/E ratio of approx. 11-13 (2026e) is almost laughably cheap compared to the US competition.

My conclusion:

We will see a massive rotation if Trump continues to push through his policies so aggressively.

Forecast: 🔮The money is flowing out of the overheated US markets back into European small caps, which provide real hardware for the "sovereignty agenda."

- AAC Clyde Space is the speculative bet on the European "new space" boom. Those who invest here are betting that Europe will build its own satellite infrastructure independently of SpaceX & Co.

- X-FAB is the solid basis. If you want to manufacture chips for the automotive revolution and quantum sensor technology in Europe, there is no way around this foundry.

The verdict: If the US tariffs put further pressure on supply chains in 2026, local champions like AAC and X-FAB will be among the big beneficiaries.
