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 (+0,91%) and 350 $SHEL (-0,19%) shares were sold from my portfolio.

The following additions were made:

• $SIVE (+11,6%) 1,500
• $AAOI (+17,19%) 50
• $XFAB (+3,32%) 400
• $SHT B (-8,01%) 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 (+3,63%)
• 
  $LPK (-0,45%)
• 
  $AXTI (+8,43%)
• 
  $MRVL (+5,79%)

Have a nice evening, everyone!

I noticed something some time ago: The deeper I look for technological bottlenecks, the more often I suddenly end up in Sweden. Not with Ericsson or Volvo, but with small and medium-sized deep-tech companies.

A few examples from my portfolio (the first four) or my watchlist:

- Sivers Semiconductors - $SIVE (+11,6%) Radio frequency and photonics components for AI and data networks

- Acconeer - $ACCON (+3,8%) energy-efficient radar sensors for industry and edge applications

- BeammWave - $BEAMMW B digital beamforming technology for future mobile networks

- Obducat - $OBDU B (-14,29%) Nanoimprint lithography for advanced semiconductor and photonic structures

- Hexatronic -
$HTRO (-3,29%) Fiber optic infrastructure for the expansion of digital networks

- Smoltek Nanotech -
$SMOL (+0%) Carbon nanostructures for semiconductors, electrolyzers and future packaging solutions

- Smart High Tech -
$SHT B (-8,01%) Special electronics and technical components for demanding industrial applications

What many of these companies have in common: They are not located at the end of the value chain, but often several levels below it. This is where new technologies are made possible in the first place. This is exactly where I look for bottlenecks.

Of course, such stocks are not for every investor. Many are small, less liquid and in some cases still a long way from stable profitability. Individual orders or capital measures can have a massive impact on share prices. Not every technology will prevail and not every company will make it to broad commercialization.

This is precisely why I do not treat them like standard stocks, but as targeted additions within a more broadly diversified technology portfolio. I entered SIVE just over 2 months ago and was already at a price return of 1,150 %, now a little less again and have taken two partial profits 😅.

The deeper you delve into topics such as photonics, sensor technology, wireless technologies or advanced materials, the more frequently Sweden appears.

Sometimes the country seems like a small, listed deep tech incubator in the middle of Europe.

Attention ⚠️ These are very speculative stocks with high volatility! No investment advice!
