@88magalhaes Lmfao actually $SPCX uses $NBIS now. Did not think of that angle.
Donβt think itβs anything newly material though for Nebius, just a fun connection.

Woah, $SPCX acquired Cursor for $60B.
I did not think it was worth that muchβ¦
Maybe network effect or data for improving models became invaluable?
Iβm sure Elon has a plan in mind, the Twitter acquisition paid extreme dividends.
$SPCX
Still holding Foci/Nextronics. There was a CPO bear post from an analyst that said there would be delays (which $NVDA denied), which caused CPO related stocks to crash.
Personally think Foci will end up a bottleneck for $TSM COUPE / $NVDA and Nextronics to be a beneficiary of optical components relative to MC in $NVDA supply chains.
We'll see how this plays out.

@hoarderresearch yep, trying my best! Always a fun time to get anonymous threats of violence when i post about $IREN excessive ATMs from time to time.
$IREN
Yeah... I'm not quite sure why everyone likes just throwing personal accusations.
Like "scam" or "memestock" every time I post a thesis.
Like when I bought $AXTI (still holding shares btw):
- spent the time mapping the InP substrate supply chain
- found analyst sources around market share
- tracked high purity indium pricing on SMM
- modeled game theory around bottleneck hikes/supply shocks.
- tracked Gov publications like seizure of optical companies or export controls
Then just posted the idea for free, cause it's a hobby.
Everyone just threw out personal insults as it went up in price...
Just for Reuters to confirm it 7M later that InP substrates can halt the AI buildout.
I'm just sharing ideas out for free, could always be wrong, and they usually take some time to play out.
But would prefer instead if folks/media played devil's advocate on the thesis side like export controls or ASP pricing power...
Over just making up narratives or personal accusations like "memestock" or "foreign institutional team" when they lack the technical depth to understand AI supply chains.

Put more concentration into the memory theme like $SNDK and others, Jan of this year.
And I'm glad my prediction with Micron + memory is playing out well!
Hope people had fun with $EWY longs too, those are up a lot.

@aletir99 When has US investors ever cared about what people in Sweden think?
I still think $SIVE has the potential to be the next $75B $LITE if they follow the same M&A route after NASDAQ Listing.
$SIVE$LITE
@aistruder CPO hasn't ramped up yet so very early. Shunsin should actually benefit the fastest though given H2 scale out with Foxconn.
Win Semi is great regardless but benefits from photonics vertical. Foci/Msscorps are more h2 2027.
$AXTI took like 5-7 months to fully play out.
$AXTI
@yangqisniper $AXTI was a fun one.
Actually every single one of my photonics ideas last year went up triple % digits. Got the entire theme + supply chain right!

@cchronobreakk I don't need to open any new US stock position when all my ideas from memory to photonics like $AAOI are still playing out?

Fun throwback to random ideas back in 2025.
Back then, $AAOI was $2B MC, $LITE was a $26B MC, $AXTI was $500M
Now:
- AAOI is $15.37B
- Lumentum is $74.47B
- AXT is $7.24B
Was working off less information back then, given it was an early theme.
Obviously nuances with ASIC programs might have been missed as more details came out.
But directionally, glad thematically my ideas turned out correct.
Feels like dejavu seeing current $3B MC optical longs like $SIVE.

Other way around, $NVDA bottlenecked the entire industry for EML capacity.
And did the same with CW capacity ONCE AGAIN with $LITE, $COHR, and $MRVL (if they have LTA in place with Celestial)
I said this a few months ago, we'd see this exact same playbook. But $AMD, $AMZN, $META, and others are just so stupidly slow that they let themselves get bottlenecked.
Now there's only a few merchant players like $AAOI, $MTSI, and $SIVE that they all need to fight over.

New reports that $AMD is scrambling for CW laser supply.
And is negotiating large-scale purchase orders for CW Lasers to ensure its production capacity is not constrained by $NVDA (Trendforce)
Obvious CW laser beneficiaries:
- $SIVE (AMD went to GFS for CPO, Sivers reference laser level)
- $AAOI (Rosenblatt analyst checks)
Lumentum/Coherent are kinda booked out way into 2028 as well.
Lumentum is especially constrained for CW capacity already from existing EML contracts (so they probably are buying from Sumitomo/Furukawa and co).
Maybe Macom and Japanese giants still have spare capacity. (disclosure, own aaoi/sivers).
I predicted this last year and said hyperscalers should go more upstream to secure capacity... at laser levels, epiwafer levels, or even inp substrate levels.
To not get bottlenecked by Nvidia.

Just as a recap, these were all my core European longs:
1. $SIVE
2. $LPK
3. $SOI
4. $RPI
5. $IQE
6. $ALRIB
7. $XFAB
Sivers: As you know by now, core laser chokepoint over next generation photonics, from 1.6T pluggables to CPO.
Embedded in many hyperscaler suppliers from Jabil to Ayar. Should go brrr 2027 but markets are forward looking, so ramps + qualifications should get priced in now.
LPK Laser - Glass core substrate "monopoly" with LIDE.
"More than 80% of major global players have selected our equipment for process validation, learning and scaling to mass production"
Soitec - Silicon photonics SoI substrate pure monopoly while coming out of legacy drag segments.
Raspberry Pi - Was my fun idea around Raspberry Pis being used for AI hardware deployments.
Previously this thing was mainly educational or hobby boards, but now used for edge/local AI. Just thought revenue increase would be extremely material and it played out well.
IQE - Critical epiwafer player for your Western photonics like Macom, Tower, Lumentum, and others.
Was kinda going under, but thought their latent capacity relative to Landmark was undervalued.
Also given how important it was, I thought that your downstream players + Govs wouldn't let it go under, so it was more of a moonshot idea earlier in the year.
Lot more derisked now, very important.
Riber - Kinda monopoly in the MBE space, exposure to Quantum / quantum dot + silicon photonics.
Found out from OSINT help from a friend latentvalue that Microsoft Quantum was buying their machines, so this was direct hyperscaler validation + kinda de-risked at current MCs.
XFab - SiC foundry backed by EU/US CHIPS Act with power semi upside. (152% Y/Y growth for their sic vertical).
Main growth was their silicon photonics foundry past 2027 that's getting evaled by nvidia. And that they're leading Europe's value chain efforts in photonics, kinda like an early tower semi.
We'll see how this plays out, thought power semi exposure + low P/B would derisk the company until they scale their photbunchonics efforts.
From my own personal thoughts:
Out of the maybe $SOI has already been re-rated the most? But I'm holding anyway.
$LPK and $ALRIB I think are still undervalued despite their monopolies.
$RPI is just kinda seeing how things go at this point, would be hilarious if they ended up like a mini nvidia for low end edge ai.
$IQE probably has a long way to go given new tower long term agreement, alongside macom. And if they convert latent capacity, I still think it has a chance of rerating like landmark.
$XFAB idk if im missing something or are markets missing something. you have nvidia as a direct eval of their silicon photonics foundry, and it's trading below replacement P/B. i think im right though.
$SIVE I see has the highest upside out of all of them given laser company ability to vertically integrate, acquire companies downstream to make their lasers more valuable, etc. Just like coherent/lumentum.
There's like 1-2 more random ones that aren't really material, but just in general.
These are the ones I've liked the most.

Iβve written a thesis on these 3 themes early on:
Neoclouds, Photonics, and Memory.
Now, itβs fun to sit back and watch all my thesis ideas play out from $AAOI to $EWY to $NBIS.
Even got my warnings right too, $IREN is still stagnant due to the $6B of constant selling pressure from the ATM, while $NBIS reaches ATHs.
But the bagholders still donβt want to admit it.
Think a core part is knowing what theme comes next with markets, then comes picking the winner + heavy concentration in them.
If you went long on software and chose the ideal stock, youβd probably end up not as happy?
Photonics is still probably the earliest out of the three.
But I can see Nebius end up like AWS one day.
And $MU / SK Hynix / Samsung potentially end up like a mini $NVDA if memory demand is structural.
$AAOI$EWY$NBIS$IREN$MU$NVDA
Ayar started off multi-sourcing with $MTSI and $LITE.
Then removed them from their website and likely made $SIVE primary source (likely for first gen).
It's every hyperscaler supplier intention to multi-source, there's nothing material being added there.
Ayar is one of the bigger CPO players, but if CPO mapping is correct more revenue should come from $MRVL Celestial, maybe Lightmatter/Lightelligence.
Ayar is also just one customer of many... This is not even including $JBL + other pluggable players that use $SIVE.
Or even O-Net producing ELS with $SIVE for Asian supply chains.
Nobody can accurately estimate revenues right now, it's just that they've been qualified into so many different hyperscaler supply chains like what I've done previously with $AAOI or $AEHR.
That when volume ramp happens... And it's a hyperscaler supplier, you expect revenue numbers to be extremely material.
$MTSI$LITE$SIVE$MRVL$JBL$AAOI$AEHR
$SIVE is likely laser ramping with $AEVA soon and $AAPL with their next refresh of Apple Watches after their recent announcement.
Havenβt seen anything credible to disprove that.
Thereβs some people without technical depth conflating TASC sensors with future Apple Watches using lasers, and donβt understand NRE volumes can carry forward years too.
AI DCs for photonics are $SIVE main focus though, anything else like Apple is a cherry on top.
$SIVE$AEVA$AAPL
@asianinvestors No, Win Semi and multiple other foundries are handling laser volume ramp.
$SIVE is the next SIVE.
Donβt think youβll find another company.
Thatβs qualified and likely primary/sole source with:
- $JBL and other pluggable hyperscaler suppliers
- Ayar and the $NVDA NVLink CPO ecosystems
While being the foundational reference laser for $GFS and pluggable/CPO/NPO deployments.
That hyperscalers like $AMD and others use, at current valuations.
Even $POET buys $SIVE lasers and Poet is about the same valuation just off having one $50m purchase agreement.
Amount of hyperscaler suppliers for 2027 into 2028 is just ridiculous.
From the general meeting today in a few hours, weβll hopefully see NASDAQ listing timelines confirmed.
So they can have room for M&A to TAM expansion and to make each laser they sell more valuable.
Following what $LITE did to grow into a $75B company.
