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.

Apparently, $SPCX is a $2.5T company now.
I did say Americans would buy anything futuristic without caring about valuations...

$SPCX
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.

@Joseph363555684 No positions in $WOLF right now, but Iβm cheering it on anyway since itβs a core part of American supply chains.

Yep, very stupid to be a bear.
When Trump is doing everything to boost markets before Midterms.
On top, your $WOLF power semi basket should go brrr from 800 VDC acceleration.
$LITE optical basket should go brrr from InP easing.
$SPCX successful IPO gives more appetite to risk on themes/IPOs (eg. Space sector).
And overall macro go brr from War/Strait peace deals.
Itβs already kind of showing, since 2026 rate hike odds also crashed from 65% -> 35% following the news. Along with crude futures dropping.
I've actually found Europe to be the most price sensitive to Iran tensions, so EU markets would probably be the most bullish overallβ¦
(South Korea/TW was originally with Sk Hynix moving directly in correlation to crude oil futures, but stopped caring after awhile).
But basically: Murica go brrrr.

@LuBtc888 I still like Leaderdrive (688017) from earlier this month, these are long term ideas I'm sharing!
$688017
@chenchuwei85698 $POET is sitting on too much after another $400m private placement. So they're near ~$1B pure cash.
Not a fan of poet, but even if their tech doesn't get qualified into hyperscalers, they can always acquire other companies to scale.

Today, there's a new report that China eased InP substrate exports.
Which is expected to relieve mass production bottlenecks in the photonics market (source: Digitimes)
My optical positions are very happy to hear this:
From $AXTI (substrates), $IQE (epiwafers) to $AAOI (lasers) / $LITE / $SIVE, and others.
Taiwanese optical players like VPEC, Landmark, and others should go brrr as well.
Just to recap: the photonics market, especially for laser companies is moreso "how much can you make" rather than how much demand is there.
InP substrates was one of the main bottlenecks affecting upstream capacity.
So if you're able to make more = more revenue.

This is gonna upset a lot of people:
But TA is astrology for traders.
It's confirmation bias + trading human psychology about entries.
Kinda like how people frontran $SPCE from $SPCX IPO expecting retail to mess up tickers by trading psychology.
$SIVE didn't go up 1900% because of the golden cross space comet firebreathing dragon candle that someone is trying to sell for $499.
It's because markets are pricing in future revenue from $JBL, $GFS that got announced.
$AXTI didn't go up 8000% because the golden waterfall candle alert sounded back at $8.
it's because of InP substrate, game theory on ASP hikes, export controls, photonics demand, and others.
If you want to figure out psychologically what other regards are believing, you use TA.
But for determining the actual upside... nah
People have been drawing $120+ TAs on $IREN for the past idk how many months none of that crap matters when there's a $6B ATM that needs to be bought through first.
It's by theme (eg. $LITE to $AAOI relations), any news catalysts that affect forward revenue, projections, macro news, earnings, float dynamics, and so on.
Then you can just derive what MC that company should be at.
So for entry points, sure you can use TA.
For determining where the stock heads, just throw the tyrannosaurs rex omega-green candle indicator out the window.
