$SOI from Soitec SA.

It isn’t just another AI infrastructure story.
The real question is: what happens if silicon photonics becomes the default way to move data inside AI clusters?
If that happens, every optical engine needs high-quality photonic material. Performance doesn’t improve through software—it depends on physics.
That’s why I’m watching $SOI.
This isn’t a company trying to build the next GPU. It’s aiming to supply a critical enabling material further down the stack. Those are often the businesses the market notices last.
Framework is simple:
• AI compute keeps scaling.
• Copper eventually becomes a bottleneck.
• Silicon photonics adoption accelerates.
• Demand for premium SOI wafers follows.
Of course, execution still matters. Customer qualifications, production scale, margins, and commercial wins all need to materialize. There are no guarantees.
But if the thesis plays out, the market may realize that the biggest winners aren’t always the companies selling the servers—they can be the companies supplying an indispensable input.
The best investments are often hidden where the physical bottlenecks are.
Now concerning TA:
Nice retest on the monthly chart to the bull market support band.
