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 (-3.52%) (Onto Innovation), $CAMT (-5.46%) (Camtek) or even $FORM (-8.52%) (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 (-5.63%) (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 (-4.27%) (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 (-4.27%) (BE Semiconductor) or $ONTO (-3.52%) (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.

Hey, GQ crew ✌️

My first post since I got kicked out about 4 weeks ago—who would’ve thought that showing solidarity with one of the members (@Klein-Anleger ) would lead to a ban so quickly? But getquin’s generosity was so BIG (and, most importantly, “on a trial basis”) that they graciously let me back into the holy grail of the GQ community 😉

So guys, learn from my mistakes: The leniency here isn’t an “infinite money” glitch! Save your solidarity for later, keep your support for other members at zero, and most importantly 🚨: No sneaky advertising for alternative financial platforms like “Cisdord” 😉😂.

Sorry, that little dig after four weeks away was a must 🤝

But joking aside…

⏳The first three months of 2026 have passed. Time for a brief interim assessment of the current status of my portfolio rebuild.

Before I started rebuilding my 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 maintain a portfolio with a maximum of 20 stocks. As things progressed, however, I realized that it probably wouldn’t stay at 20—the number is more likely to rise to around 30 positions (+/-)—

♟️My Focus & Strategy:

To put it simply: The clear focus is on growth 🚀. Dividends play a rather secondary role here. Here, I’ll show you my shopping list—or rather, what my portfolio should look like in the future. The stocks I’ve already bought are marked with a green checkmark; those without a checkmark are ones I’m still waiting on ⏳

🏭INDUSTRY: ~10–15%

REMAINING: ~5–10%

Given the global political situation—especially because of that 🍊 in the White House, whose tweets cause more tsunamis 🌊than actual natural disasters—and the current drawdown in the S&P 500 (which is actually working out great for me right now and bringing me a lot of joy 🤩), I’m consequently in the red on some of my purchases so far 💦🫧.

But hey, we’re investing for the long term, after all, right? So, taking it easy, keeping it chill 🥱 I’ll most likely hold off on making any more purchases for the time being over the next few days or weeks, park my cash elsewhere or put it in a money market account, and wait to see where the market settles or wait for it to stabilize.

What do you guys have on your watchlist?

Are you sitting on the sidelines right now, or how are you handling the current situation?

@Get_Rich_or_Die_Tryin
@Tenbagger2024
@Max095 And, of course, all the other members

Okay, that’s enough for now 😂

That’s all from me for now ✌️
