Today we are leaving the field of acute AI bottlenecks (HBM/Memory, Power & Cooling, Advanced Packaging, Energy/Grid) and take a look at future AI bottlenecks.

Here I see, among other things Test & Metrology, because modern AI systems are becoming increasingly complex. More layers, more integration, smaller structures and higher power densities. At the same time, fault tolerance is decreasing massively. Or to put it another way:

‼️ The industry is slowly moving towards "zero tolerance".

Even minimal deviations can affect yield, energy consumption or stability in the future. Precisely because of this This is precisely why the requirements for measurement, control, verification and precision along the entire production chain.

Level 1: Core Metrology (measurement & process control)

For me, this is the structural core. Put simply, it's about making the smallest deviations in modern production processes visible and controllable. Company $ONTO (+5,8%) (Onto Innovation), $CAMT (+3,36%) (Camtek) or even $FORM (+6,84%) (FormFactor) address precisely this level.

Level 2: Test & Verification (functional testing & verification)

It is checked whether complex systems function stably at all. As integration density increases, the importance of test systems also grows considerably. It is often almost impossible to correct errors later on. Companies such as $TER (+6,8%) (Teradyne) show how important Test & Verification becomes with increasing system complexity.

Level 3: Yield Engineering & Integration Control

This is where a lot of value is currently shifting within the stack. With topics such as HBM, chiplets or 3D integration, the requirements for precision, yield and thermal control are increasing massively. For me, for example $BESI (+3,17%) (BE Semiconductor) is very close to this development.

Level 4: Specialized Metrology (high-precision special metrology)

Future optical systems and new integration architectures will further increase the requirements for precision and control. Increasingly, the bottleneck no longer lies in the integration itself, but in the ability to combine highly complex components without errors and maintain stable quality. Companies such as $BESI (+3,17%) (BE Semiconductor) or $ONTO (+5,8%) (Onto Innovation) are addressing precisely this development.

The more complex modern systems become, the more critical the ability to make minimal errors visible and controllable becomes.

Emerging areas such as photonics (optical data transmission), optoelectronics (combination of electronics and lighting technology) or CPO/Co-Packaged Optics (optical components directly next to the chip) are also driving this development, as increasingly complex stacks, optical connections and integration architectures are being created.

Hello to the GQ community ✌️

My first post after being kicked about 4 weeks ago - who would have thought that solidarity towards one of the members (@Klein-Anleger ) would lead to a ban so quickly? But the goodwill of getquin was so BIG (and above all "on trial") that they graciously let me back into the holy grail of the GQ community 😉

So guys, learn from my mistakes: the goodwill here is not an Infinite Money glitch ! Save your solidarity, reduce your commitment to other members to zero and the most important thing 🚨: No surreptitious advertising for alternative financial platforms like "Cisdord" 😉😂.

Sorry, the side blow after 4 weeks of abstinence had to be 🤝

so joking aside...

⏳The first three months of 2026 have passed. Time for a brief interim summary of the current status of my reconstruction.

Before I started rebuilding the portfolio, I naturally thought about what strategy I wanted to pursue in the coming months and years - especially with regard to stock selection and weighting.

To be honest, my original plan was to keep a portfolio with a maximum of 20 shares. In the course of time, however, I realized that it will probably not stay at 20 stocks, but that the number is more likely to increase to around 30 positions (+/-).

♟️Mein Focus & my strategy:

In a nutshell: The clear focus is on growth 🚀. Dividends tend to play a subordinate role. Here I show you my shopping list and what my portfolio should look like in the future. The stocks I have already bought are marked with a green tick and without a tick, I'm still waiting ⏳

What should the sector/country weighting look like?

Let's start with the "desired"

🌍country weighting:

🇺🇸🇨🇦USA ~60%

🇪🇺EUROPA ~20%

🇯🇵JAPAN/ASIA ~15%

Rest ~5%

Sector weighting should be as follows:

💻TECHNOLOGY: ~30-35%

💸FINANCE: ~ 20-25%

HEALTHCARE: ~ 10-15%

🏭INDUSTRY: ~ 10-15%

REST: ~ 5-10%

So, what has happened since the beginning of the year?

Due to the global political situation - especially because of this 🍊 in the White House, whose tweets cause more tsunamis 🌊than real natural disasters - and the current drawdown in the S&P 500 (which is very convenient for me right now and gives me a lot of pleasure 🤩), I am accordingly under water💦🫧 with some of my purchases so far.

but hey, we're investing for the long term, aren't we? So easy going, all relaxed 🥱 I will most likely not make any more purchases in the next few days or weeks, park my cash position elsewhere or put it in overnight money and wait and see which zone the market settles in or wait for it to stabilize.

What do you have on your watchlist?

Are you currently waiting or how are you dealing with the current situation?

Ok, that's enough now 😂

that's it from me for now ✌️
