Summary: Long SIVE as undiscovered InP laser supplier for AI optical interconnects; entire photonics ecosystem bullish on Goldman's 10x TAM growth report.

structural marker; pre-classified as canonical yfinance ticker

$SIVE – If you are wondering if it is too late to invest, it isn’t and here is why.

Goldman Sachs just unveiled their Optical Communications industry map for the AI infrastructure buildout. The full ecosystem laid out – IC Design, Materials, Optical Components, Packaging and Testing.

Guess what? $SIVE is not on the map, yet.

The highlights from Goldman:

TAM growing from $15B to $154B. Scale-up optical interconnects within racks and super-nodes are the real driver. NVIDIA’s GPU clusters jumping from 72 to 576 GPUs by 2027-2028, with interconnect dollar value per computing unit going from $315K to $9.4B. A 29x increase per unit.

Silicon photonics penetration jumping from 6% in Q1 2024 to 46% by Q4 2028. CPO commercialization starting in 2026. The shift from copper to optical is structural and accelerating.

In the laser/light source segment, Goldman maps $LITE, $COHR, $AVGO, $AAOI – the obvious ones. Sivers is nowhere to be seen.

$SIVE powers Jabil’s 1.6T LRO architecture. Win Semi is their confirmed foundry partner. They sit upstream of the entire optical interconnect stack with InP lasers everyone needs.

When Goldman publishes the next iteration of this map, $SIVE will most likely be listed on the US Nasdaq and big enough for institutional coverage. Which means institutions will try to shake the ground just so they can catch up.

This report is extremely bullish for the entire photonics ecosystem.

Being early pays. Having conviction pays even more.

Summary: Holding SNDK long for the foreseeable future, endorsing bullish hyperscaler capex/AI storage thesis.

@ParadisLabs Great minds think alike. 100% agree with you on this. Holding for the foreseeable future $SNDK.

A lot of you feel like it's too late to buy $SNDK?

Imo, it's not late at all.

Pretty high level thoughts/summary:

1.  Forecasts estimate hyperscaler capex to grow YoY.
2. AI training + inference demands fast storage alongside GPUs.

Summary: Long photonics/scale-up CPO ecosystem (COHR, LITE, MRVL, TSM, AXTI, LWLG, SIVE) on NVIDIA's captive supply chain for GPU-to-GPU optical interconnects growing 142% CAGR to 2030.

CPO is forecasted to grow at 142% CAGR from 2026 to 2030, excluding ELS.

Scale-up CPO surpasses scale-out before 2030 and becomes the dominant market.

GPU-to-GPU optical interconnects (replacing copper inside AI clusters) eat the bigger pie, not rack-to-rack switching.

Scale-up is closer to the GPU package. Different supply chains. Different attach economics. Different multiples.

Who supplies scale-up? NVIDIA already answered that question with $4B into Coherent $COHR and Lumentum $LITE for lasers, $2B with Marvell $MRVL for NVLink Fusion optical I/O, and TSMC ($TSM) SoIC for the 3D packaging. Add InP substrates (AXT $AXTI, IQE $IQE, Sumitomo), SOI wafers (Soitec $SOI), polymer modulators (Lightwave Logic $LWLG), and ELS specialists (Sivers $SIVE).

Scale-out is the Broadcom + module vendor game. Scale-up is the NVIDIA captive ecosystem. Knowing which bucket each name plays in matters.

I’m long photonics

Just in case you’re wondering why I’m so bullish on CPO.

Like $SIVE (Lasers), Shunsin (Packaging), MSSCorps (Yields), Win Semi / $TSEM (Foundry).

Memory just ran (still going). Photonics is just warming up. But $7.6T over 6 years doesn't get fully priced in 6 months. Plenty of runaway left.

Summary: Bullish photonics/optics as the next AI infrastructure chokepoint after memory; Goldman's $7.6T capex forecast not yet fully priced in.

US photonics/optics basket; removed failed NPAB/IIVI, added AAOI

Goldman just put a number on the AI buildout: $7.6T from 2026-2031.

They explicitly flag optics as the next “buy out the store” chokepoint after memory.

The numbers behind the thesis:

+Compute alone is $5.1T of the $7.6T total
+Annual AI capex grows from $765B in 2026 to $1.6T in 2031
+Data center cost per MW jumped from $10M (cloud era) to $15-20M (AI era)
+A single $50K accelerator depreciates $10K/yr but goes economically obsolete faster than the schedule
+NVIDIA’s GB300 NVL72 packs 72 processors per rack, linked by hundreds of thousands of km of cabling

In the repot they state: similar episodes of intense, short-term pricing pressure are likely to recur across other critical components such as interconnect, optics, storage, and packaging.”

Meaning the same dynamic that just sent memory parabolic is queued up across the entire physical layer of AI infrastructure.

The “AI factory of the future” data center will pack 576 GPUs per rack at 500+ kW, requiring liquid-only cooling and millions of GPUs deployed at the >1 GW scale.

None of that scales without optics.

Memory just ran (still going). Photonics is just warming up.

Full disclosure:

Goldman is confirming what’s been playing since the late last year. A lot is already priced in.

The alpha is front-running institutions, not reading their reports.

But $7.6T over 6 years doesn’t get fully priced in 6 months. Plenty of runaway left.


Bullish Win Semi. The market is not fully pricing it in. Win Semi is the largest pure-play compound semiconductor foundry in the world – 65% global market share.

Summary: Long Win Semi on undervalued AI data center, optical comms, and LEO satellite growth; market not pricing in strong Q1 results and capacity ramp.

Win Semi (3105.TWO) just had its best ER in years. The market is not pricing it in

EPS up 30x YoY. Revenue +28% YoY. Q2 guidance up 14-16% QoQ. And that’s with capacity utilization still only at 60%.

The two growth engines going forward: Optical Communications and LEO Satellites.

AI data center revenue expected to more than double this year. Optical PD products entering mass production in Q2 with significant ramp in H2. 4-inch InP line capacity expanding by multiples this year to meet demand.

Win Semi is the largest pure-play compound semiconductor foundry in the world – 65% global market share. Without them, the entire III-V ecosystem grinds to a halt. They make the GaAs, InP, and GaN chips that go into 5G base stations, satellites, defense radar, AI data center optics, EVs, and quantum sensors.

Win Semi is the confirmed outsourced manufacturing partner for Sivers’ DFB lasers and laser arrays – scaling high-volume production for CWDM and DWDM applications, CPO and next-generation optical interconnects.

When $SIVE scales, Win Semi scales with it.

They are not just Sivers’ foundry. They are the foundry for the entire compound semiconductor universe. WiFi 7 chips for $QCOM. RF front-end modules for $AVGO. EML lasers for hyperscaler transceivers. Power amplifiers for LEO satellite constellations.

When the optical interconnect market goes from $15B to $154B, Win Semi is in the path of every single dollar. There is no scaling photonics without scaling Win Semi.

The market is not fully pricing it in.

Summary: Endorses Goldman CPO supercycle report as bullish for the photonics/CPO sector.

CPO/photonics basket; removed failed NPAB/IIVI, added AAOI

@aleabitoreddit Goldman Sachs report today confirms what you have been front running the last 6 months. This is beyond bullish for the photonics space, specially for the CPO buildout.

GS has mapped out the CPO supercycle with unholy projections of 9x TAM projections.

From $15B to $154B in a short timeframe. CPO contributing $91B.

This is why I’m so bullish on $SIVE as one of bleeding edge CPO laser suppliers.

Reminds me of the horse Golden Tempo.

But for https://t.co/dTZ1udXDhO


After the Goldman Sachs report it is clear the CPO market is going from $15B to $154B. Sivers sits in the laser layer of that buildout, still at a tiny valuation compared to its peers. When small caps get institutional validation, the repricing will happen in days, not months.

Summary: Bullish Sivers Semiconductors: Goldman validates CPO market ($15B→$154B), tiny valuation vs peers, institutional repricing imminent in days.

The results are in – $SIVEF 🇺🇸 ended up pulling $SIVE 🇸🇪 higher.

After the Goldman Sachs report it is clear the CPO market is going from $15B to $154B. Sivers sits in the laser layer of that buildout, still at a tiny valuation compared to its peers.

The most interesting part of today’s move – this isn’t $SIVE catching up to $SIVEF anymore. The Swedish listing is now leading the price action. The premium is moving in the other direction.

The winner is retail investors like us that are front running institutional players.

When small caps get institutional validation, the repricing will happen in days, not months.

$SIVE vs $SIVEF – 1.5 days of Sweden stock exchange being closed and the gap is already 20%.

That tells you exactly how fast the market is repricing this name.

$SIVEF: $4.92
$SIVE: $3.99 (kr38 converted)

Who catches up to who?

My guess is that $SIVE closes the gap UP. https://t.co/8WP6fiOjAD


$SIVE / $SIVEF right now could be the generational run when you look back a year from now. Up 1,200% YTD and still plenty of room to run. At $1.5B MC, 2x is in sight. After that, execution + US listing + institutional investment + guidance is what takes us to the +5000% generational run, 5x to 7x from here.

Summary: Long SIVEF as the next generational run: 2x near-term, 5–7x longer-term on US listing + institutional inflows.

Hindsight is 20/20, but $SIVE / $SIVEF right now could be the generational run when you look back a year from now. Up 1,200% YTD and still plenty of room to run.

$AXTI did it in 2025, still going in 2026. Guess who is coming for that throne.

At $1.5B MC, 2x is in sight. After that, execution + US listing + institutional investment + guidance is what takes us to the +5000% generational run, 5x to 7x from here.

When things get this obvious, the big players come in. Expect institutions to flock in at any moment.

Looking back is easy. Looking ahead and having conviction is really, really hard.

So you’re telling me all I had to do was buy $AXTI one year ago and retire my entire bloodline? https://t.co/yN1V7m5uZ6

Win Semi (3105.TWO) is one of the easiest trades you can do this year.

Embedded in the CPO buildout alongside $SIVE. Sits on the foundry side of the III-V/InP bottleneck, supplying high-power InP laser arrays for CPO, LiDAR, and sensing.

Then the earnings hit.

EPS up 30x YoY. That’s 3000% growth. Not something you see every quarter.

Revenue +28% YoY. Q2 guidance up 14-16% QoQ.

The market hasn’t fully priced it in yet.
‘Only up 200% YTD.’

Classic sleeper build. Set it, sleep well, let it compound.

My position is up and I'm not selling anytime soon. I'm betting on my core thesis. If everything in optics is completely sold out, as soon as $POET gets back on its feet the re-rate will be obvious and fast.

Summary: Holding POET long despite CFO/NDA drama; bets core optics thesis intact and re-rate will be fast once company recovers.

$POET up 30% on no news. Remember that news follows price. Someone always knows.

My position is up and I’m not selling anytime soon.

Let me explain why.

Last week $POET ran from $8 to $16, crashed back to $7, and most of you sold. I respect that – lack of trust in management is a completely valid reason to exit.

But something doesn’t add up. Dig a little deeper than just the CFO violating an NDA.

This is pure speculation on my part – but it’s either that their technology wasn’t ready and they wanted out, or that Marvell wanted them out for reasons that have nothing to do with the technology itself.

For me this became a binary event. I already took the -45% hit. At that point I’d rather own the stock and bet that the technology they’ve been advocating for is real.

I still don’t like management. I still don’t like how they used influencers to pump this stock and believe me I’m not getting paid.

I’m betting on my core thesis. If everything in optics is completely sold out, as soon as $POET gets back on its feet the re-rate will be obvious and fast.

This is not investment advice. This can play out the other way entirely.

For my R/R tolerance it’s worth holding.

You do you.

$POET – the CFO went out and violated an NDA, causing Marvell to cancel all their deals.

There’s no easy way to say this. What a clusterfuck.

Just when the stock was having one of its best runs ever – $5 to $16 in a month – we get this. Not related to the technology. Not https://t.co/sKSeGWIBaT


Still bullish all CPU plays. $AMD just reported a monster ER

Summary: Still bullish entire CPU basket (AMD, INTC, ARM) on structural shift to 1-to-1 CPU/GPU ratio and agentic AI spending just getting started.

$AMD just reported a monster ER and sent every CPU stock to the moon. Up +15% after hours.

Since I started publicly sharing my portfolio I’ve been clear about where I’m putting my money and why:

The AI buildout:

Photonics / Memory / CPUs / NeoClouds

So why CPUs and why now?

$AMD said it best on the call: in the past the CPU-to-GPU ratio was 1-to-4 or 1-to-8. Now it’s moving toward 1-to-1. And with agentic AI, you could end up with more CPUs than GPUs. That’s a structural shift.

Here’s how my CPU basket is doing since I entered:

$INTC (January) – entry at ~$55, bought the local top because I’m the worst trader ever. Now +105%.

$AMD (late March) – entry at ~$202, bought the local bottom because I’m the best trader ever. Now +76%.

$ARM (late March) –entry at $137 after the CPU for AI thesis started gaining traction. Now +62%.

If you think you’re late I can assure you you’re not. Not super early either. But agentic

AI spending is just getting started and CPUs are in the critical path of every dollar spent.

Still bullish all CPU plays.

Summary: Long SIVE on CW laser supply gap through 2026-2027; Lumentum's earnings call confirms only 20% self-supply, benefiting Sivers' Glasgow InP fab and Ayar Labs partnership.

$LITE just handed us a confirmation on a massive CW laser supply gap for 2026-2027. This is great news for $SIVE

From Lumentums earning call:

CEO Michael Hurlston, on CW laser insourcing:

“We’ve seen a little bit of tension in our own supply line, externally to get lasers from the external market, CW lasers. As such, now we’ve allocated more of our fab capacity to CW lasers. In our mix, roughly as we think about it in the guide, it would be about 20% of our modules would have our own CW lasers. It’s still minority, but we’d expect to step that up through time.”

Meaning the largest Western InP laser manufacturer only self-supply 20% of their CW laser needs. The other 80% has to come from somewhere.

Why this matters for Sivers

For the skeptics the question has always been “why would a tier-1 transceiver maker source CW lasers from a small-cap Swedish company when Lumentum makes their own?”… Well the CEO just answered that directly.

Lumentum cannot make enough of their own. Not this year. Not next year. The Greensboro ramp is a 2028 story at the earliest.

Meanwhile the supply-demand imbalance on EMLs is still above 30% and widening. Pump lasers hit a constraint so suddenly Hurlston called it “unanticipated.” The bottleneck is not resolving – it’s migrating up the stack. CW lasers are the next node in that chain.

What Sivers brings to this

+ Glasgow InP fab producing CW DFB laser arrays for 800G+ transceivers today, not in 2028
+ CW-WDM MSA promoter member alongside Lumentum – they sit at the same standards table
+ Sivers lasers integrated into Ayar Labs’ SuperNova light source platform – partnership expanded in December 2024 specifically around manufacturing readiness, with volume shipment ramp targeted for mid-2026 to late-2027

If you want to short a stock I recommend you look elsewhere…

Couldn’t ask for better news.

Long $SIVE.


Summary: Long AAOI: vertically integrated laser supply chain, $200M+ 1.6T orders, and structural undersupply benefit AAOI while constraining LITE.

$LITE just confirmed the transceiver market is structurally undersupplied. $AAOI makes its own lasers and is ramping to fill the gap

CEO Michael Hurlston said demand exceeds supply by more than 30% on EMLs. On transceivers specifically: “We could ship quite a bit more this quarter… quite a bit more in the guide had we not the supply constraints we see.”

That demand has to go somewhere.

While Lumentum is experiencing “tension in the external market” for CW lasers, forcing them to reallocate fab capacity just to partially self-supply. AAOI does not have this problem.

They manufacture their own CW lasers via proprietary MBE and MOCVD processes, with plans to scale to over 2 million CW lasers per month by December 2026. While competitors are scrambling to source externally in a tight market, AAOI controls its own supply chain end to end.

Three specific data points from today’s Lumentum call directly underpin the AAOI thesis:

First, Lumentum’s transceiver supply-demand gap is “appreciable” and in the 30%+ range. Every module Lumentum cannot ship is potential share for a qualified, ramping alternative supplier.

Second, the CW laser shortage in the external market – which Lumentum just disclosed – does not constrain AAOI. Their vertical integration is specifically the structural advantage that differentiates them when the external supply chain tightens.

Third, 1.6T is where Lumentum says margins are “definitely better” and where they are “ahead” in design execution. AAOI has already secured $200M+ in 1.6T orders and is ramping production starting Q3 2026.

AAOI earnings are May 7, the market will be looking for: how much of the $124M 800G backlog started converting to revenue in Q1, whether 1.6T qualification timelines are holding, and early margin signals as the product mix shifts from 400G.

Management guided Q1 at $150M-$165M. Any beat alongside forward guidance that points toward the $1B target will confirm that the backlog is real and executing.

Even if they don’t beat guidance this time around the supply is so constrained that any drop will most like be bought up.

I’m long $AAOI


Summary: LITE's post-ER dip is short-term noise; long-term gains intact.

@fable_7887 Don't focus on PA on the short term, it is due to $LITE ER, short term noise for long term gains.

@Ren_aramb Is this why the smaller foreign CPO names like SIVE etc are dipping today? I see how this validates the CPO thesis, but I’m trying to understand whether it helps the small suppliers too, or mostly just the big players like Corning.


Summary: Long NBIS to $500, no doubts; expects target by mid-2027.

@Sandeman52 But sir, I’m almost 3x on $NBIS in under 3 months, wouldn’t it be best to find the new shiny object if I did proper DD? Of course $NBIS it will go up to 500$, 0 doubts about it. But when, is more likeky mid 2027.

If you have researched a stock for a very long time, own it, and it’s doing well, don’t leave it for shiny objects.

There are many shiny new objects out there.  Just because they move fast and everyone is talking about them does not mean you should just chase it blindly.

Summary: Long Nynomic (M7U) as AI photonics/pharma/AM re-rate still not priced in; AAOI flagged as cleaner but riskier leverage play.

Since I’ve been pointed out on this reasoning, here is my take;

1.The dilution math hurts you at €8 entry, helps you at €21. SOTP ex-LayTec is ~€87.5M. Current MC is ~€132M. You’re paying for the operating subsidiaries and getting LayTec for free.

2.TOWA isn’t the right comp. It’s a pure-play cyclical with the volatility to match. The right comp is Halma or Spectris – diversified holdings with embedded specialty subs that compound through cycles and trade 3-4x revenue.

3.“Hidden asset no longer hidden” – institutional ownership is still 19%. One analyst has modeled LayTec separately. No major US coverage. Discovered by retail, not by institutional capital.
Agreed on segment disclosure being the key catalyst. Watch September.
$SIVE and $AAOI are cleaner leverage but carry more single-name execution risk. Different risk profiles.

If trailing financials were all that mattered, this analysis might be right. But markets are forward-looking. M7U and its subsidiaries are positioned to capture the AI photonics, FDA PAT pharma, and metal AM waves simultaneously – and the re-rate hasn’t been priced in yet.

I see quite a few posts and thoughts on $M7U (Nynomic), here are my thoughts:

$M7U is one of those names that looks like a perfect AI photonics monopoly until you actually look at what you’re buying.

The thesis most people are running with: LayTec, the German subsidiary, has a


Summary: Author's top CPO plays ranked by conviction: AAOI as biggest position, followed by SIVE and LITE.

@ParadisLabs I’m beginning to think we really do think alike, you are probably just better at math.

Favorite CPO plays ranked:

1) $AAOI ( my biggest position too)
2) $SIVE
3) $LITE

Current favourite CPO plays:

- $AAOI for vertical laser + full engine integration (earnings today should be fun)
- $SIVE for premium CW DFB arrays
- $LITE for nvidia’s CPO programs + they dominate CW/EML laser arrays (yet to properly digest earnings tbh)

Im long $LPK / $LPKFF ... You are still early, do your own DD, this a speculative play I'm willing to take. Bullish!

Summary: Long LPKF/LPKFF; glass substrate laser tech (LIDE/through-glass vias) positioned for AI packaging ramp 2027-2030, up 100% in 20 days but author says still early.

Im long $LPK / $LPKFF

LPK is now the first 100% stock I’ve called since I began rotating into a new basket of stocks.

It’s been only 20 days. You need to understand why glass has the spotlight right now.

AI datacenters are hitting a physical wall. Copper interconnects can’t keep up with the bandwidth demands of 1.6T speeds and beyond. Glass substrates solve this – lower signal loss, higher bandwidth, less heat. LPKF’s own management has stated the question is no longer whether the shift will occur, but when the ramp-up phase will begin.

LPKF owns the laser process that makes glass substrates work.

Their LIDE technology enables deep glass processing without generating micro-cracks – allowing defect-free formation of through-glass vias and cavities for high-density integration.  No other company has this at production scale. And now they’ve gone further.

LPKF has already supplied equipment capable of forming 3D optical waveguides directly inside glass substrates to a customer. The equipment is already installed. They are fully prepared to provide the same to additional customers on demand.

Glass substrates for packaging is the 2027 story. Glass substrates for co-packaged optics – where lasers replace copper entirely – is the 2028-2030 story. LPKF is building the equipment for both right now.

More than 80% of major global players have selected LPKF equipment for process validatio. Partners include Samsung, Intel, and Corning.

The financials don’t tell the whole story, but at least they don’t hurt to look at.

FWD P/E of 11-12.5x for 2027 dropping to ~7.8x in 2028. Clean balance sheet. Zero dilution overhang.

100% in 20 days is the market starting to figure this out.

You are still early, do your own DD, this a speculative play I’m willing to take.

Bullish!

I'm long $PDFS. Q2 and Q3 are where it shows up in the numbers. Bullish of what's to come.

Summary: Long PDFS; H2 2026 acceleration thesis driven by eProbe ramp, Exensio AI beta, SecureWise expansion, with 20% revenue growth reaffirmed.

$PDFS Q1 2026 earnings just dropped. Q1 laid the foundation. Q2 and Q3 are where it shows up in the numbers. Bullish of what’s to come.

Revenue: $60.1M – up 26% YoY. Beat consensus. Operating profit up 75% YoY. Net income up 56% YoY. EPS $0.31, up 48% YoY. Non-GAAP operating margin 25%, up from 18% a year ago.

Q1 was a consolidation quarter sequentially, so a small pullback is expected.

Revenue stepped down from $62.4M in Q4. Backlog dipped from $254M to $246M. The acceleration is not in the rearview – it’s the H2 2026 story, gated by eProbe deployments ramping and Exensio AI hitting beta in Q3.

Fewer than 5% of manufacturing data collected at fabs is actually used in analytics today. PDFS is the platform being built to change that – across fabs, fabless, equipment vendors, OSATs, and foundries simultaneously.

What comes next (Q2 / Q3)

The eProbe shipped in Q1 begins contributing revenue in Q2 – immediate tailwind. Five more machines targeting shipment through the rest of the year, two going to net new customers. Installed base doubles from 6 to 12 by year-end with ~10 on subscription. Management said demand is already outpacing their ability to build machines.

Exensio AI analytics hits beta in Q3. Double-digit million dollar bookings in Exensio Test and fab control in Q1 alone – those convert to revenue through Q2 and Q3. Characterization and DFI activity in Q1 expected to convert to strong bookings as the year progresses.

SecureWise expanding into OSATs, fabless, and foundries after Intel publicly standardized on it. Each new category is an incremental revenue layer stacking on top of the existing base.

Cash builds in H2. CapEx front-loading in Q1 means cash grows in the back half as eProbe subscriptions kick in and collections accelerate.

20% revenue growth reaffirmed. Long-term targets of 27% operating margin and 77% gross margin tracking ahead of schedule – and faster than management originally planned.

I like the CEOs enthusiasm, and I really like this management team:

In 100 quarterly calls the CEO has never said this: “this is the most interesting time I have ever seen for the industry and PDF Solutions in particular.”

Q1 laid the foundation. Q2 and Q3 are where it shows up in the numbers.

$PDFS is one of those steady compounders that let’s you sleep well at night Plenty of tailwinds, great management, solid financials and a couple of catalyst up its sleeves.

I’m long $PDFS.

I'm buying the dip. Added to my position on the dip. I'm long $AAOI.

Summary: Buying AAOI dip: EPS miss immaterial vs capacity-constrained revenue ramp to $1.1B+ in 2026; InP laser shortage also validates SIVE and LITE supply chain opportunity.

The market sold $AAOI off 11% for missing EPS by two cents (?). I’m buying the dip.

The miss was $0.02. The company raised >$200M in equity and deployed $68.7M in CapEx in a single quarter building factories.

You have to spend money to make money. This is a company investing ahead of the largest revenue ramp in its history.

Q1 delivered record revenue for the fourth consecutive quarter. $151.1M. Up 51% YoY. Up 13% sequentially. Management is explicitly saying demand is not the constraint – capacity is. Their internal demand number is $1.4-1.5B for 2026.

They guided to $1.1B because that’s what their factories can physically produce.

Q2 guidance: $180-198M. Another 30% sequential step up. Then Q3: management guided 60-80% sequential growth over Q2. Q4 similar to Q3. By mid-2027, $471M per month of data center transceiver revenue – $5.6B annualized from one product category.

The capacity ramp:
800G: 138K/month today → 420K/month by Q4 2026 → 550K/month by mid-2027.
1.6T: 10K/month today → 230K/month by Q4 2026 → 380K/month by Q4 2027.
ELSFP for CPO: starting Q4 2026 at 5K/month → 400K/month by Q4 2027.

Management confirmed an industry-wide InP laser shortage that will “persist and get more acute” with the advent of CPO.

This directly validates the $SIVE and $LITE supply chain opportunity.

When the CFO of one of the largest transceiver manufacturers in the world says InP laser shortage is getting more acute – that’s primary source confirmation that the external laser market is structurally undersupplied.

The compression today is entirely a product mix transition.
400G making way for 800G and 1.6T, both of which carry meaningfully higher margins.

Management is calling last quarter’s $200M order announcement “SMALL” compared to what’s to come.

Full year 2026 guidance: >$1.1B revenue, >$140M non-GAAP operating income.

To be honest, I’m usually the most bullish person in the room but these guys are on something else. They know demand exceeds supply through mid-2027, and they will make the most out of it.

Two risks worth naming.

Customer concentration (don’t do us a POET) – three customers are 98% of revenue.

Management fairy dust sniffing – the company has a historical pattern of promising large ramps and delivering them late.

Added to my position on the dip.

I’m long $AAOI.

This directly validates the $SIVE and $LITE supply chain opportunity.


Summary: Long PDFS; Q2/Q3 growth will drive further upside after strong Q1 beat and 13% gain since initial call.

$PDFS the market seems to be reacting favorably towards the up and coming growth for Q2 specially Q3.

Up 13% when I called it 2 weeks ago, the best part is what is coming their way.

Steady sometimes wins the race. https://t.co/Xrxcv65Fqo

Summary: Bullish MXL re-rate as scale-up DSP play; MRVL and AVGO cited as the other two beneficiaries of 1.6T optical DSP demand in AI datacenters.

$MXL is up 415% in one month and 20% today.

The market is re-pricing the scale-up play.

Every optical transceiver in every AI datacenter – every 800G module connecting GPU to GPU, rack to rack, building to building – needs a DSP. A Digital Signal Processor. It’s the chip that takes the raw optical signal and makes it usable. Without it, the transceiver doesn’t work.
MaxLinear has shipped millions of units of their Keystone DSP platform, now in production at multiple major hyperscalers across the US and Asia supporting 400G and 800G deployments.

Today, about 30% of the optical transceiver TAM is scale-up and 70% is scale-out. MaxLinear was mostly a scale-out play. Now they’re both.

Annapurna – the 1.6T AEC and 3.2T onboard electrical retimer platform for scale-up applications. Foundational to the next wave of data center optical architectures including LPO, LRO, AECs, XPO, and co-packaged optics.

Only 3 companies make DSPs for 1.6T optical interconnects: $MRVL, $AVGO, and $MXL. The first two are $50B+ giants. MXL just crossed $2B market cap.

When $AAOI announced they’re ramping 800G to 550K units per month and 1.6T to 380K units per month by end of 2027 – every one of those modules needs a DSP.
MaxLinear is one of three companies that can supply it.

The market is paying a premium for scale-up exposure. MXL just proved it has it.

The re-rate is real.

Bullish.

$MXL just reported and infrastructure revenue grew 130% YoY, and it is up 42% AH. Feeling the fomo.

Summary: Long Shunsin on implied AVGO CPO order win; interprets Taiwan 'denial' as NDA-constrained confirmation with 1,240% EPS growth projections.

I’m long Shunsin ($6451.TW)

About the company

Shunsin is a Taiwanese hidden gem, Foxconn-backed optical transceiver and SiPh advanced packaging company operating across Taiwan, China, the US, Malaysia, and Ireland.

They assemble and test optical modules, SiP modules, and passive optical components, exactly the supply chain that CPO deployments depend on.

About the news

Shunsin is giving us an indirect confirmation in the most Taiwanese way possible, filing a “clarification” denying they secured $AVGO CPO orders.

In Taiwan market convention, that’s basically a wink and a nod.

NDAs don’t let you confirm. Listing rules don’t let you confirm. So you “deny” it.

The growth projections come with the attached news. 1,240% EPS growth estimates don’t come from nowhere.

This is the proper way to give a confirmation without breaking an NDA.
(Here is looking at you $POET)

Bullish news! 🇹🇼

For those of us on IBKR, there was a disposition which made it impossible to buy.

The disposition happens because of there was too much volatility, new buys were blocked, you could only hold or sell.

The restriction has been lifted since last week.

Go bananas at your own risk! NFA.

I bought a small speculative position on the drop to ~€7-8... I'm long $P4O

Summary: Long P4O (held) as upstream MEMS glass wafer supplier; intends to buy SILEX post-IPO; bullish LITE on $400M+ OCS backlog scaling in AI datacenter supply chain.

P4O trades on Xetra/Frankfurt; euro price ~€7-8 context matches

$SILEX, the TSMC of the MEMS world, just IPO’d on Nasdaq Stockholm. I’m hunting possible upstream beneficiaries. I’m looking at you $P4O (PlanOptik)

Silex Microsystems is the world’s leading pure-play MEMS foundry. They manufacture MEMS – micro-electromechanical systems – for other companies.

One fab in Järfälla, Sweden. SEK 1,385M in 2025 revenue. 27% EBIT margin. Q1 2026: 34% EBIT margin. Expanding cleanroom capacity 35%.

Optical Circuit Switching is one of their largest customer segments. Confirmed in the IPO prospectus.

Inferred supply chain mapping:

$P4O glass wafers → $SILEX MEMS foundry → $LITE OCS switches → $GOOGL Jupiter/Taurus AI datacenters

Plan Optik makes the specialty glass wafers. Silex processes them into MEMS mirror dies. Lumentum assembles those into optical circuit switches. Google deploys them in their AI datacenters.
Lumentum’s OCS backlog is $400M+ and scaling fast.

The Silex IPO just put SEK 8.9 billion on the MEMS foundry node in that chain. $P4O market cap: ~€35M.

P4O plays two glass stories:

Plan Optik is explicitly named as a leading company in the glass interposers market for advanced semiconductor packaging – alongside Corning and 3D Glass Solutions.

Yole Group describes their high-flatness, controlled-transmission glass carrier model as one of the best-positioned approaches for the emerging glass carrier market.

TSMC CoPoS enters small-volume trial production 2027, mass production 2028-2029. Samsung SEMCO glass core substrates targeting mass production 2027. Intel glass core substrates before 2030.

Every one of those ramps needs qualified glass substrate suppliers. P4O is already in the ecosystem.

Management’s own guidance says “series ramp-ups from 2027 onwards are expected to result in a further significant increase in Group revenue.”

Two structural AI buildout waves.

Both converging on 2027.
One confirmed. One inferred.
One speculative.

At a €35M MC company.

Important considerations:

> Silex doesn’t disclose customer names – the P4O link is inferred, not confirmed
> P4O is a micro-cap with extremely thin liquidity
> Financials are weak right now – €11M revenue, net loss in 2025 from one-off costs. Clean balance sheet, €3.35M cash, no debt.
> I bought a small speculative position on the drop to ~€7-8

That doesn’t exactly mean this translates to material revenue boosts unless they start a price hike – given glass wafers are likely a very small part of $LITE OCS BOM.

The Silex IPO confirms that the market will pay a significant premium for a qualified, scarce, hard-to-replicate position in the OCS supply chain. P4O’s argument is that it holds exactly that position – one node further upstream.

I’ll only add to this position if I get primary source confirmation.

I’ll start a position on $SILEX when the dust settles.

These two are the last men standing in a market the giants decided wasn't worth their time and they are ready to rip the benefits of this privileged position. Macronix already reported NAND revenue up 382% year over year in Q1 2026.

Summary: Long Macronix and Winbond as the only IDMs with fabs to fill the 41.7% MLC NAND capacity gap left by Samsung/Hynix/Micron exits; supply constraint lasts 1-2 years.

Macronix International Co. listed on TWSE as 2337.TW

Samsung just shipped its last 2D NAND in June. Kioxia, SK Hynix, and Micron aren’t taking new volume orders.

Global MLC NAND capacity drops 41.7% in 2026. Nobody is stepping in to replace it.

Nobody except two Taiwanese niche memory powerhouses with their own wafer fabs.

Macronix (https://t.co/sy3Vhnt1qa) – IDM specializing in NOR flash, NAND, and eMMC for automotive, industrial, and IoT. One of the only companies globally that can fill the 4Gb to 32Gb supply gap Samsung left behind.

Gross margin expanded from 17% to 40.8% in twelve months.

Winbond (https://t.co/CFIQG8taOT) – Total memory solutions provider covering specialty DRAM, NOR flash, SLC NAND, and secure flash for automotive, industrial, and communications.

Number one globally in SPI NOR flash with 27% market share.

These two are the last men standing in a market the giants decided wasn’t worth their time and they are ready to rip the benefits of this privileged position.

Macronix already reported NAND revenue up 382% year over year in Q1 2026. They shifted to monthly price negotiations because the market moves too fast for quarterly contracts.

Industrial computers, automotive electronics, medical devices, networking equipment. These don’t run on 3D NAND. They need the old stuff. And the old stuff is disappearing fast.

When the big three exit a market and two companies are left with the only fabs capable of filling the gap, you don’t ask whether demand is there, you ask how long the supply constraint lasts. Nobody knows (1-2y?) so act fast and rip the benefits.

Summary: Long memory complex (SNDK, MU, SK Hynix, Macronix, Winbond) on supply-constrained market + 56% CAGR AI inference demand through 2031; 'a lot more juice to run'.

Memory prices are going absolutely vertical.

Look at the Korea export price data. DRAM +18%. DRAM excluding modules +35%. Flash memory +47%. SSD +140%. In one month.

This is a supply-constrained market running into 56% CAGR AI inference demand through 2031.

Main beneficiaries.

$SNDK – +500% YTD. Pure-play NAND. Only name with clean exposure to the storage side of the AI buildout. Entire supply sold out through 2026.

$MU – +124% YTD. Market cap just crossed $700B. HBM fully booked. DRAM average selling price up 32% quarter over quarter. New York megafab breaking ground January 2026.

SK Hynix – the HBM pure-play. Operating margins approaching 70%. Every HBM, DRAM, and NAND unit for 2026 already committed. Planning US ADR listing because Korean market valuation doesn’t reflect what global capital is willing to pay.

The NAND bit demand chart  makes it a lot clearer: 286 exabytes in 2025. 1,686 exabytes by 2031.

AI inference driving 56% CAGR – three times faster than training and traditional workloads combined.

Secondary beneficiaries

While the big three chase HBM, they walked away from legacy 2D NAND.

Two Taiwanese names own that vacuum.

Macronix (https://t.co/sy3Vhnt1qa) – NAND revenue +382% YoY. Gross margin from 17% to 40.8% in twelve months.

Winbond (https://t.co/CFIQG8taOT) – Number one globally in SPI NOR flash. Own fabs. Lead times past nine months.

What is clear is that memory is no longer a commodity business it’s a structural shift.

You are not early, but there is definitely a lot more juice to run.

HOLY SMOKE.

What the hell is this?? Memory prices are going absolutely insane.

$100K into $DRAM – ETF. I'm not planning to manage this position for the foreseeable future. The memory supercycle is not a short-term trade – it's the infrastructure layer that every AI workload runs on.

Summary: Opened $100K long position in DRAM ETF for 18-year horizon; bullish on memory supercycle as AI infrastructure layer with compounding HBM/DRAM/NAND demand.

I just opened my one month old son his first investment account.

$100K into $DRAM – ETF.

I’m not planning to manage this position for the foreseeable future. The idea is to hold until he turns 18 or rotate if it is absolutely necessary.

I’m a firm believer in the AI buildout. The memory supercycle is not a short-term trade – it’s the infrastructure layer that every AI workload runs on. HBM, DRAM, NAND – demand compounds as the models get bigger and the inference scales.

Let’s see if he can outperform my active portfolio.


I'm long FOCI (3363.TWO). Up only 103% YTD. Positioned perfectly before the CPO ramp up begins.

Summary: Long FOCI (3363.TWO) as dominant FAU supplier for NVIDIA/TSMC CPO architecture; mass shipments guided 2027-28 with Feynman GPU CPO pull-forward.

I’m long FOCI (3363.TWO).

Up only 103% YTD. Positioned perfectly before the  CPO ramp up begins.

FOCI makes FAU. Fiber Array Units are the critical physical interface that connects optical fibers to silicon photonics chips in a CPO architecture.

Without a precisely engineered FAU, the light doesn’t get into the chip. No FAU, no co-packaged optics.

FOCI’s FAUs command a dominant share in NVIDIA’s CPO architecture – confirmed via cross-referenced patent filings between FOCI, Himax, and TSMC.

Morgan Stanley estimates FOCI will be the leading FAU supplier for NVIDIA and TSMC in the first year of silicon photonics mass production – up to 50% market share.

NVIDIA just pulled CPO forward. Feynman GPUs in 2028 now planned to include co-packaged optics. Five years ahead of earlier estimates. And FOCI’s own management guided mass CPO shipments starting 2027-28.

FOCI is the critical interface between light and compute in NVIDIA’s next generation architecture.

FOCI is one of the five Taiwanese companies I’m positioning for CPO buildout.

Long FOCI (3363.TWO)

Started a position in $DGXX today. Bought the dip at $7. Bullish $DGXX

Summary: Initiated long DGXX at $7; bullish on Cerebras AI colocation deal with $2.5B expansion potential vs $620M market cap.

Started a position in $DGXX today. Bought the dip at $7.

This is the home play for Cerebras AI chips.

They surveyed every data center operator available and chose DGXX. 10-year, $1.1B colocation agreement. Up to $2.5B in expansion options. Phase 1 operational by December 2026.

That expansion ceiling alone was larger than DGXX’s entire market cap when the deal was signed.

Now they have a second tenant already signed and GPU-as-a-Service revenue starting.

$620M market cap. $2.5B in potential contracted revenue. A $50B anchor customer going public this week.

There is risk attached to this play:

DGXX flagged its own securities as “highly speculative” in their 8-K. Revenue doesn’t start until late 2026 and depends entirely on delivering a 40MW campus in Alabama on schedule.

Phase 2’s additional 25MW is conditioned on securing adequate financing – which means dilution risk is live.

The ATM upsizing is already on the table.

Current operations are loss-making with crypto-exposed revenue streams. And Cerebras itself has 86% of 2025 revenue concentrated in two UAE entities with an operating loss of $145.9M – your anchor tenant has its own execution risk.

This is a bet on whether they can build on time and whether Cerebras delivers on the compute demand that justifies the contract.

The asymmetry is real if both execute.

I’ll be watching Q1 earnings in just a few days on May 15 to size big or trim.

Bullish $DGXX

Bullish FOCI (3363.TWO)... FOCI is confirmed sole FAU supplier for TSMC COUPE Gen 1 and Gen 2... Mass production H2 2026 with AMD as first adopter

Summary: Long FOCI as sole FAU supplier for TSMC COUPE Gen 1/2, mass production H2 2026, positioned in $60.99B optical-engine/FAU CPO TAM by 2028.

This is an excellent representation as to why I’m so bullish on many Taiwanese CPO names. In particular FOCI (3363.TWO) stands out for FAU.

We all know by now that Goldman Sachs mapped the CPO supply chain at a $97B TAM by 2028.

As @ParadisLabs breaks down the report:
———————————————————
CPO 2026-2028 TAM of $97B:
1.Optical engines & FAU: $60.99B
2.Fiber cable & MPO: $20.71B
3.ELS: $10.83B
4.Shufflebox: $4.21B

Then looking at how that ramps over the years:
> 2026 - 1%
> 2027 - 26%
> 2028 - 73%
———————————————————

So why FOCI?

FOCI is confirmed sole FAU supplier for TSMC COUPE Gen 1 and Gen 2 per Ming-Chi Kuo supply chain checks and Tianfeng Securities. Mass production H2 2026 with AMD as first adopter.

The exclusivity window is Gen 1 and Gen 2.

The nuance:

Gen 3 opens to competition.

The COUPE exclusivity is specifically TSMC’s architecture, not every NVIDIA FAU application.

Since I began trading I’ve tried to positioned myself accordingly to what should be the next bottleneck and then let it play out.

Memory > CPU > Photonics

The up and coming theme is CPO.

I might not be right or on time but I’ll try to be early.

Bullish FOCI (3363.TWO)

Even after the Marvell NDA fiasco, the stock begun to gain momentum, remember news follows price, someone always nows.

Sometimes it’s more obvious than others.

Options flow going crazy – On May 11 alone, 266,000 contracts traded with a heavily bullish put/call ratio of 0.41 vs. the usual 0.27, and implied volatility hitting 167.

This was a tell, on no material news.

Now we know.

After the Marvell chaos, this is exactly the kind of customer win the market needed to see. One Tier-1 dispute does not kill the technology. The optical interposer technology is still top notch.

Earnings on May 26 just got a lot more interesting.

The sound investment would have been to bail after the Marvel news, and cut your loses. I respect and applaud that.

I’m a little degen, sometimes you just have to stick to your intuition, hot sector, in demand  technology, bullish options flow.

I’m on the fence of what I’ll do moving forward, but I’m up 120% and probably not selling before ER.

You do you, NFA.

$POET – continuation of a long.

Did you get a chance to buy last week?

The trigger for me was Marvell orders confirmed by the CFO. Great find by @crux_capital_.

Then add the $SIVE and $POET partnership on top.

These two aren’t competing – they’re building the same stack https://t.co/4k4AIQ2jD6


Summary: Long SIVE on annual report; bullish ecosystem read extends to WIN Semi, POET, AEVA, and NOK as beneficiaries of Sivers CW laser/CPO ramp.

POET Technologies listed on Nasdaq as POET

$SIVE. You are not ready for what’s to come.

The 2025 annual report dropped.

Serenity already covered most of the report in depth, here is what stood out the most to me.

The financials have been restated for PCAOB compliance – preparation for a potential Nasdaq New York dual listing.

Win Semi (3105) capacity lock-in during a CW laser bottleneck.

TAM expansion into pluggable transceivers – multiple new customer qualifications.

The serviceable market now includes pluggable optical interconnects alongside scale-up and scale-out CPO architectures.

Hints at a broader group of hyperscaler suppliers in qualification.

CW laser shortage confirmed – directly from management.

Volume production signals for H2 2026:

> POET partnership: prototypes demonstrated H1 2026, production readiness targeted end of 2026.

> LIDAR: largest customer increases production starting Q4 2026

> Lightium AG partnership for the 3.2T+ cycle.

> Partnership to integrate CW lasers directly onto TFLN wafers.

If you are a conservative investor you will most likely focus on the 2025 financials and scrutinize them. If you are ambitious and forward looking you will see beyond that – and be in awe at the amount of positive news coming their way.

This is obviously massive for $SIVE.
But it’s also bullish for $WIN Semi who holds the capacity, bullish $POET whose production readiness targets end of 2026, bullish $AEVA whose volume production with Sivers starts Q4 2026, and if confirmed bullish $NOK – who the financials and geography suggest is Sivers’  photonics customer.

So a massive win for the whole ecosystem.

Q1 2026 report drops May 29. I can’t wait.

Long $SIVE.

$SIVE 2025 annual report analysis.

TLDR: Extremely Bullish.

Sivers main growth vector is CPO, but they've TAM expansioned to pluggable transcivers + multiple new qualifications/development.

So I'm betting they win. NFA. I hold a position in $IPWR.

Summary: Long IPWR; holds a position betting B-TRAN wins the 800V DC solid-state breaker socket in NVIDIA Rubin Ultra racks, with prototype in 2026 and potential production ramp 2027.

$IPWR There is a hidden chokepoint inside NVIDIA's Rubin Ultra rack that is being overlooked… remember this name B-TRAN

AI racks used to pull 10 to 50kW. Rubin Ultra is pushing toward 600kW and the roadmap points at megawatt racks. At that density, old 400V AC power delivery falls apart. Too much current, too much copper, too much heat. So the entire industry is ripping it out and moving to 800V DC.

800V DC fixes the power problem but creates a new one. DC current does not have a natural zero-crossing the way AC does. When a fault hits, the arc does not want to die. Mechanical breakers are way too slow to catch it. At 800V across a 120kW rack it is a fire.

So the rack now needs a new kind of breaker. Solid state. Reacts in microseconds. NVIDIA's own 800V reference architecture lists it as required infrastructure

This is where $IPWR shines.

Think of a power switch as a gate on a road. Almost every gate only opens one way. If you need traffic flowing both directions, you bolt two gates together. Two gates means double the parts, double the cost, double the heat 🔥

$IPWR built a single gate that flows both ways on its own. They call it B-TRAN. One part instead of two. Traffic barely slows down so it runs cool. In its target jobs it wastes roughly a quarter of the energy a conventional setup does.

A safety breaker is the perfect fit. It sits open nearly 100% of the time and only slams shut when something breaks. When a part is on almost constantly, wasted energy is the entire ballgame. Run cooler, win the socket.

The demand is up there. $WOLF just guided its data center power business to grow 30 to 50% per quarter. The 800V transition is happening now, not in 2030.

The execution is the bet.

On May 14 $IPWR signed an LOI to co-develop a B-TRAN solid state breaker prototype for a US hyperscaler building on NVIDIA's Rubin Ultra 800V architecture.

Prototype targeted for end of 2026, with a possible production ramp in 2027. Their pipeline grew about 50% since the start of the year. New CEO came from 11 years at $ON, hired specifically to convert lab projects into real orders.

The not so rosy part:

$IPWR has $0 revenue today. No production orders yet. The whole thesis rests on one thing: turning a prototype eval into a repeating purchase order. Until it lands, this is a lottery ticket on B-TRAN becoming the default safety standard for 800V.

But it is a lottery ticket with a floor. No factories, no debt, $16M plus in cash after a recent raise, slow burn. It cannot implode the way $WOLF did a couple years back. The downside is dead money, not zero.

This is a binary event with capped downside and uncapped upside. Still size accordingly to a pre revenue company.

This is the kind of name where if the design wins this explodes hard.

By the time there is coverage, the entry is gone. So I’m betting they win.

NFA. I hold a position in $IPWR.


Summary: Broadly bullish on AI infrastructure across the full stack; trading around it for the past year.

AI infra basket: hyperscalers/networking/power; no single ETF covers all

Most people think the AI buildout is just a couple of stocks – Memory, CPU, GPU, NeoClouds, Photonics..

$SNDK, $MU, $ARM $INTC, $AMD, $NBIS, $LITE, $AAOI, $TSEM, $SIVE

The reality is there’s so much more to it.. I built a complete map of the AI buildout – at least the one I’ve been trading around for the last year.. I put that map on my Substack… 12 layers deep.

Since I’ve seen it circulating on here, I’ll just post it myself.

The hard part isn’t knowing the full stack – it’s making sense of it.

Why is photonics down today but memory isn’t? Why is CPO so relevant in the AI buildout?

Bullish AF on AI infrastructure.

Let’s go find the next 1000% stock ⚡⚡


Summary: Holds a bullish stance on AAOI; describes it as a favorite photonics company and 'in love' with the position.

It's been 3 days on Substack and I'm already #2 in trending, a bestseller with one article, and I have the support of the Substack Head of Partnership for any requests or problems I find.

I mean, I love X's immediacy and how fast news travels here, but all I'm getting is 40-50% taken from subscription fees, a chat riddled with bugs, and images that don't load, no way to have a channel with all my subscribers.

As a product person, I hate looking at bugs and not being able to do anything about them when the solution seems obvious. I think I'm going to start documenting them and emailing the head of product here... come on @nikitabier @elonmusk, step it up!!!

Anyway, wouldn't it be too funny if a Pikachu ranked #1 on a serious platform? I always try to follow the funniest outcome.

You can follow me there, free or paid. I'll be posting my first company evaluation with a scoring framework and risk profile recommendation in the coming days.

I'll start with one of my favorite photonics companies, $AAOI, which for sure is one complicated stock, love-hate relationship... and I'm in love.

Fading Jensen sounds like financial suicide. I'd rather bet on him than listen to these so-called experts on here.

Summary: Endorses being long NVDA; calls fading Jensen financial suicide.

@aleabitoreddit Fading Jensen sounds like financial suicide.

I’d rather bet on him than listen to these so-called experts on here.

To each his own.

If you haven’t noticed too with my other investment themes with 800V DC and CPO recently.

It’s investing in $NVDA, America’s national champion in AI, and securing their supply chains.

Many things feel technologically difficult with yields to substrate supply.

I'm not only not selling, I'm buying more. this has legs for months to come, well into 2027

Summary: Adding to SNDK; bullish memory sector broadly (MU, Kioxia, SK Hynix) with legs well into 2027.

$SNDK memory is looking mighty fine…

It’s not just them – $MU, Kioxia, SK Hynix too.

It’s not like me to brag… but my first batch of $SNDK is up over 1,200% from 8 months ago – and this has legs for months to come, well into 2027.

Summary: Long BRUN below $30, targeting $40+; bullish on 12x backlog growth, FCF-positive NeoCloud model, and $1.44B Dell agreement.

$BRUN - I’m long Brun

For all the people who were hating on this name. For all the tourists who got in, made a quick buck, and got off at the first sight of trouble.

Especially for those creating FUD around one of the fastest-growing companies in the NeoCloud ecosystem from a 10% shares unlock event.

THANK YOU!

This is a company that contracted backlog grew 12x in 6 months. Management is guiding to triple again by year-end. And they’re doing it FCF positive, while every major NeoCloud peer burns cash and you are selling over a misread lock-up structure??

The Thinking Machines Lab deal alone – $471.7M, 36 months, take-or-pay – covers 21% of their entire year-end TCV target in a single contract. The customer pays whether they use the GPUs or not.

Dell signed a $1.44B purchase agreement and is financing the buildout through Dell Financial Services – aligned to customer contract timelines. No dilutive raises needed.

The real risk to watch is November 8 – when the remaining 43.9M shares become eligible. I’m planning for that, not this Monday.

I was late to this name, but now my average is below 30.

LFG!!! See you at +40 ⚡


I'm recommending my mom and her friends to just buy $DRAM

Summary: Recommending DRAM ETF for general investors and NBIS for more tech-savvy ones as the top R/R plays today.

@babyfolio I’m recommending my mom and her friends to just buy $DRAM, the more tech savvy. Add in some $NBIS.

"I have cash. What should I buy?"

I probably get this question 100 times a day.

My answer is always the same.

There is only one sector today that, in my opinion, offers truly unmatched R/R

I don't care if you disagree. 😅

If you want the simple, sleep-well-at-night answer:


Summary: Strongly bullish AI infrastructure sector on Iran-US deal reducing oil/inflation and giving Fed room to cut.

If Iran and the US finalize this deal, it is huge news and mega bullish for AI infra – the conclusion of a filler arc we really didn’t need.

Fasten your seatbelts. Oil comes down, inflation pressure compresses, the Fed gets more room to move – and all that’s left is for Trump to get Warsh on his good side.

Then off we go.

Bullish AF on AI infra.


Summary: Bullish entire AI infrastructure stack (compute, memory, interconnect, power) as durable winner regardless of model-layer commoditization.

Satya Nadella just posted something that validates the entire AI buildout thesis from the very top of the stack.

The model is commoditizing. The durable value is the learning loop a company builds on top of the model.

He splits it into two assets:

Human capital -- the knowledge, judgment, relationships, and pattern recognition of your people.

Token capital -- the AI capability the firm builds and owns.

He says the real opportunity is building a learning loop where human capital and token capital compound together.

If the model layer is commoditizing then the durable returns are not in the model makers. They are in the infrastructure that powers every company building its own loop. Compute. Memory. Interconnect. Power.

The full stack underneath the application layer.

The model wars will have winners and losers. The infrastructure underneath gets bought either way.

Bullish the AI buildout.

Every layer. If you want to understand them in detail, check out my Substack.

I've been long Kioxia ($285A.T) since January, but last month I sized up – and it doubled in just one month. I'm sizing at any weakness.

Summary: Long Kioxia on violent earnings beat, $56B discount to SNDK, and upcoming US ADS listing; broadly bullish memory sector.

I’ve been long Kioxia ($285A.T) since January, but last month I sized up – and it doubled in just one month. It’s now one of 10+ names in my portfolio up triple digits.

Memory is finally getting the re-rating it deserves.

Kioxia – the SNDK of Japan – just delivered the most violent earnings beat in the memory space this cycle. Top 3 NAND manufacturer globally, and coming to US markets via ADS listing.

The numbers speak for themselves.

Revenue +84.5%, Operating Profit +318%, Net Profit +364% – all in a single quarter. Shipment volume actually declined. Pure ASP expansion did all the work.

Kioxia owns 51% of the fabs that make SNDK’s chips, yet trades at a $56B market cap discount to SNDK. That gap closes when US investors get access.

Memory is a theme that can’t be stopped, if you are not in this what are you waiting for. I’m sizing at any weakness.

Bullish AF memory. NFA.

I’m long Kioxia $285A.T

Summary: Long IQE on irreplaceable non-Chinese InP epiwafer position, geopolitical moat, and expanding Tier-1 foundry relationships in AI photonics.

$IQE x $TSEM just announced a multi-year InP epiwafer supply agreement.

IQE is the non-Chinese InP epiwafer source Tower needed. That’s a geopolitical moat that is ever so crucial in this political complex tape.

200Gb/s pluggables today. 400Gb/lane modulators + optical circuit switches next. IQE is being designed into the full optical roadmap for AI data centers.

Shat makes this so interesting – IQE sued Tower in 2022 for IP theft. Today Tower grants IQE a royalty-free porous silicon patent license as part of the deal.

Former adversary becomes anchor customer, if you can’t beat them? Join them. That only happens when your product is irreplaceable.

$LITE $MTSI were already IQE optical anchors. Add $TSEM and now you have three Tier-1 foundry relationships in the AI photonics stack.

When the market hands us lemons, we make lemonade. I position myself after the drop at 45 and 32. Now I can rip the benefits.

I’m long $IQE

$BRUN – I’m long.

It’s not even been 10 days since the FUD event and we are already on our way to ATH.

To everyone selling a misread lock-up: thank you. Only 10% unlocked (~4.88M of 54M). The other 90% or ~43.9M stays locked until Nov 8. I’m planning for it, not for 10%.

Meanwhile backlog grew 12x in 6 months, guided to triple again by year-end, and they’re doing it FCF positive while every NeoCloud peer burns cash. The Thinking Machines deal alone ($471.7M, 36mo, take-or-pay) covers 21% of year-end TCV. Dell financing the buildout, no dilutive raises.

Beat across the board vs. Q3 guidance… raised AI revenue outlook and strong Q4 guide is a bullish read-through

Summary: Bullish JBL on beat + raised AI guide; bullish read-through for SIVE, AAOI, and broader CPO/photonics ecosystem on hyperscaler capex strength.

I’ve said it in the past, Jabil might be the best thing to happen to $SIVE

Jabil (JBL) – Q3 FY2026 Results (reported June 17, 2026)

Q3 Highlights:

+Net revenue: $8.8B
+GAAP operating income: $445M
+GAAP diluted EPS: $2.59
+Core operating income (Non-GAAP): $504M
+Core diluted EPS (Non-GAAP): $3.16

Beat across the board vs. Q3 guidance (consensus was ~$2.83-3.23 core EPS range).

Q4 FY2026 Guidance (raised):

+Net revenue: $9.2B – $10.0B
+Core operating income: $589M – $649M
+Core diluted EPS: $3.80 – $4.20

Key quote from CEO Mike Dastoor: “AI infrastructure demand remains extremely strong, and our full-year AI-related revenue outlook is now meaningfully higher.” He also cited better-than-expected recovery in Automotive and Connected Living.

JBL is a major EMS (electronics manufacturing services) player deep in AI infrastructure supply chains – servers, networking, data center buildout.

The raised AI revenue outlook and strong Q4 guide is a bullish read-through for the broader AI infrastructure stack, including names like $AAOI, $SIVE, and the CPO/photonics ecosystem.

The $9.2B-$10B Q4 guide is a significant step-up that signals hyperscaler capex is not slowing.

Hyper bullish for my photonics names.

$SIVE above 100 SEK or $10 is just an open invitation for institutional investors.

Bullish $SIVE
Bullish $AAOI

I'm long $NOK ... The market is still pricing the legacy telecom company. It is not pricing the domestic photonics infrastructure play that Nokia built through the Infinera deal. ... Bullish AF $NOK

Summary: Long NOK: market misprices legacy telecom valuation vs. underappreciated domestic photonics packaging franchise via Infinera acquisition, CHIPS Act backing, and reshoring thesis.

I’m long $NOK

$NOK not being up at least 30% on this news just lets me know most people are missing the turnaround story, the geopolitical angle and the bet on America.

Nokia is 10x-ing photonic chip packaging capacity at its Allentown, Pennsylvania facility. Commercially available by end of Q3.

The numbers confirmed from the June 16 release:

-- ~$30M Nokia capex, plus ~$4M Pennsylvania state aid and ~$10M federal CHIPS investment tax credit
-- 500+ new jobs, nearly doubling the PA workforce
-- $500M+ projected economic impact over 5 years
-- Part of Nokia's broader $4B US R&D and manufacturing commitment

Less than 2% of global semiconductor advanced test and packaging happens in the US. Nokia's Allentown plant is one of the only domestic sites packaging photonic chips into optical modules for AI data centers. Their optical tech can cut energy usage by as much as 75%.

This facility came from Infinera. Nokia acquired Infinera in February 2025.

Allentown traces directly back to Infinera's decades of work in photonic integrated circuits, coherent optical technology, and domestic optical manufacturing.

When people look at $NOK and see a sleepy European telecom equipment maker, they are missing that Nokia absorbed one of the most important US-based photonics manufacturing assets in existence and is now scaling it 10x with government money behind it.

The market is still pricing the legacy telecom company. It is not pricing the domestic photonics infrastructure play that Nokia built through the Infinera deal.

Reshoring is its own thesis now, and it has government money and a Q3 deadline attached to it.

When less than 2% of global ATP happens domestically and Washington wants that number to climb, the few companies that already own US photonics packaging capacity become strategically valuable in a way that has nothing to do with quarterly telecom revenue.

It is a $20B+ telecom giant and the Allentown expansion is a small piece of the total business.

For a name the market still prices as legacy telecom, getting a domestic photonics packaging franchise with CHIPS Act backing essentially for free inside the valuation is the kind of mispricing I like.

The market is misreading this headline. I rather trade the supply chain.

Bullish AF $NOK


Summary: Author states NBIS is the only company he would go all-in on, endorsing continued conviction long position at ATH.

$NBIS is having an incredible run, reaching ATH.

Looking back, who have been the bigger names on this ticker with a big conviction play?

I always come back to guys like @Sandeman52 – this guy has been all in on $NBIS for over a year.

Being all in on $100k takes conviction. Being all in at $18M? Bruh… this is on a different level.

I’ve said this many times – $NBIS would be the only company I would go all in on.

The hardest thing to build in the market is conviction, and conviction pays when you are right.

This guy started with 50k 12 years ago and is now at +18M, over ~36,000% in 12 years, which is ~ 50% CAGR.

Being consistent pays and being consistent and right at the same time pays even more.

Give this guy a follow – he is helping retail grow its own conviction, which in such shaky markets is something we all need.

Ok, new CAGR is dropping:

63.5% over a span of 12 years.

Memory is still one of my biggest bets. The shortage is structural, not cyclical. This is my largest memory position and my first 10x.

Summary: Bullish all major memory names (SNDK, SK Hynix, MU, Kioxia) on structural DRAM/NAND shortage driven by AI rack upgrades, Vera CPU SOCAMM demand, and datacenter storage growth.

$SNDK is almost at 1500% since I first bought it. Memory is still one of my biggest bets.

Memory plays are crushing it this AI cycle, but at every opportunity the doomsayers call them cyclical and not worth the investment. This has happened since the rally started and it will keep happening. Make informed decisions and hold with conviction. Ignore the noise.

Here is a refresh on how insane the demand for memory is, from my own research.

The NVL72 rack upgrade from GB300 to VR200 increases the memory bill of materials by 435%. Memory is now the single largest generational cost increase in the entire BOM, bigger than the GPU jump itself. Networking and optical interconnect is the second largest. Read that again. The memory content increase outpaces the GPU increase in NVIDIA's own next-gen rack.

Now layer in the Vera CPU supply math.

$20B in CPU revenue at $8,000 ASP is 2.5 million CPUs. Assuming the same SOCAMM configuration as NVL72, which NVIDIA has not confirmed for standalone Vera, each carries 1,536GB. Total demand is 30.72 billion Gb. Total annual SOCAMM supply from all three major DRAM makers is approximately 30 billion Gb. Vera alone consumes the entire supply before a single NVL72 ships. The shortage is structural, not cyclical.

There is more plays than just $SNDK

$SNDK. Pure-play NAND with growing datacenter exposure across the AI storage stack. Datacenter revenue up 645% YoY last quarter. KV cache, inference, and RAG workloads are driving a structural shift in NAND demand. They are entering multi-year supply agreements with financial guarantees from hyperscalers. Management expects datacenter to become the largest NAND market in 2026. This is my largest memory position and my first 10x.

SK Hynix. The world's leading HBM supplier. HBM4 is inside Vera Rubin. Dominant share of NVIDIA's HBM allocation. The anchor of the DRAM side of this trade.

$MU. Largest US DRAM manufacturer. HBM and LPDDR5X capacity constrained through 2027. Sole LPDDR5X SOCAMM supplier for Grace Blackwell, now expanding into Vera Rubin. It is only a matter of time before $MU becomes my second 10x.

Kioxia. The other pure-play NAND name. Full year fiscal 2026 revenue up 37% YoY to $14.7B. Net profit roughly doubled. Entire 2026 NAND production already sold out. KV cache SSD mass production targeting 2027. NAND flash prices up 70-75% QoQ in Q2 2026 alone. Also preparing a US listing, which means this trade is about to get a much wider audience.

I have been calling memory names since I began posting on X with 50 followers back in January. Now we are at ~ 40,000, I hope more people get to ride what to me always seemed crystal clear.

And here is the thing about a 1500% gain. The hardest is holding.

That conviction did not come from a single tweet. It came from understanding the supply and demand picture deeply enough to sleep through the noise.

That is exactly why I wrote my first full deep dive on memory for Substack, on $SNDK to be precise.

I set out to answer one question. In the middle of 2026, should I still be recommending memory to the people who follow my work? Does memory still have room to run? If yes, why? If no, why not? And what does $SNDK specifically have in store from here. Am I trimming, adding, or cutting it all.

Good read to build your own conviction.

Bullish memory. NFA.

As of today $SNDK is my first 10x banger on my AI buildout portfolio since I bought it just 6 months ago.

You have to understand how FUD works to make it your best ally. Make informed decisions and hold with conviction.

Memory plays are crushing it this AI cycle. But at every https://t.co/NKwHlkV1Kx


SK Hynix. The world's leading HBM supplier. HBM4 is inside Vera Rubin. Dominant share of NVIDIA's HBM allocation. The anchor of the DRAM side of this trade.


It is only a matter of time before $MU becomes my second 10x.


Entire 2026 NAND production already sold out. KV cache SSD mass production targeting 2027. NAND flash prices up 70-75% QoQ in Q2 2026 alone. Also preparing a US listing, which means this trade is about to get a much wider audience.


I'm long, so I only trim some and wait for more good news.

Summary: Still long TRT; trimming some but holding for more upside.

I hope my subs are going to the bank cashing in their gains on $TRT

I’m long, so I only trim some and wait for more good news.

LFG! https://t.co/eoh8sRw8Jz


my best performing stock, $SNDK. Yes, even after 6,500%, there's so much more to come

Summary: Long SNDK; author holds it as best performer and claims significant upside remains even after 6,500% gain.

What an incredible past two weeks it’s been for me on Substack. There are almost 3,000 of us in my Substack community now! Reached bestseller status and hit number 2 in rising finance names!

My first post, “The 12 Layers of the AI Bottleneck,” went viral, with more than 10,000 readers and 150 likes. People have translated it into Korean and Chinese, and even folks at $NBIS have used it to illustrate where the next best play is.

I also released my first deep dive, on one of the most popular names out there and my best performing stock, $SNDK. Yes, even after 6,500%, there’s so much more to come.

This week I met with several leaders at both Anthropic and OpenAI. What an enriching experience it is to hear from the people building what I consider one of the most significant leaps in human evolution in the last 300 years.

One conclusion I’m landing on, and I’m sorry to say it since it’s such a big topic here: Physical AI is not here yet. Build your stack around Agentic AI first, fewer moving parts, then apply it to the physical world. As a small, forward-looking position, sure. But not as my main investment theme.
I treat my portfolio like a product roadmap. I focus on the next quarter to reach my goal, not on what’s coming down the line in 2-3 years. But the vision and the goal are always set on the future.

Here’s what’s coming in the next two weeks:

• A deep dive on $AAOI. A complicated company, high opportunity and high risk.

• A deep dive on one of the most popular AI names out there, $NBIS, with a personal take from someone inside the company. It crossed the $300 ATH just a few days ago, can it go even higher?

• My full portfolio review: entry timelines and % allocations over the last 12 months, in chronological order, which themes, why, and where I’m putting my money now.

• A weekly chat where you can ask me anything in detail about any stock in the AI buildout and my investment strategy.

Let’s make a killing this cycle! LFG!!!


The next $MU? It's $MU. A year ago, $MU was the only memory stock I knew about, and it's almost up 1,000%… yeah, I'm not selling. I'm riding the AI memory profit supercycle.

Summary: Still holding MU long; dismisses other memory names and rides the AI memory profit supercycle.

$MU $SKHynix $Samsung $SNDK $Kioxia

A lot of people are trying to find the next memory stock to go parabolic… in companies that aren’t profitable yet, that are going through restructuring…

Sometimes things are just NOT that complicated…

The next $MU? It’s $MU. A year ago, $MU was the only memory stock I knew about, and it’s almost up 1,000%… yeah, I’m not selling.

Not stopping, not slowing down.

Bullish AF memory.


Summary: Long NAND ecosystem (SNDK lead, MU/Samsung/Hynix/Kioxia secondary, SIMO/FADU controllers) on structural inference-storage demand via NVIDIA CMX.

Interesting piece by FADU that validates the memory thesis and confirms why NAND players like $SNDK have such a long way ahead.

Structural demand, not cyclical.

NVIDIA is giving the inference-storage bottleneck a product name: CMX. It turns KV cache into a permanent flash tier that scales with every GPU and every agent. 32-64TB of NAND per drive today, scaling toward 256TB.

In my SanDisk deep dive I wrote: “Training is a phase. Inference is forever.” CMX is NVIDIA putting that on a spec sheet.

The read-through, by NAND exposure:

Pure-play NAND: $SNDK, Kioxia (285A)
NAND-secondary: $MU, Samsung, SK Hynix.

CMX wants a specific kind of SSD: large-block, read-dominant, multi-tenant, power-efficient. That’s a controller and architecture story too.

Controllers: $SIMO, FADU

Bits and architecture. Same catalyst, two layers.

Inference is forever. So is the memory it runs on.

This is a great piece explaining why Nvidia’s CMX rack could drive massive NAND demand. I highly recommend giving it a read.

Summary: Long MU and SNDK on memory supercycle: 40-50% QoQ ASP gains through 2026-27, China supply not a threat until 2028.

$MU $SNDK

Memory’s Bull Run Just Got Louder.

Jefferies just put hard numbers on what makes me so bullish for memory.

3Q memory pricing up 40-50% quarter over quarter. Another 30-40% in 4Q. Then a 40-45% hike rolling into 2027.

40-50% in a single quarter, and it keeps climbing.

This is the supercycle thesis getting stamped by a major bank. The pricing power is accelerating, and it’s nowhere near done.

The long-term contracts are now only with the cloud companies. CSPs are locking up 50% of capacity, and Jefferies thinks that climbs to 70%. Less and less left for everyone else. When the hyperscalers vacuum up the supply, the names with their own contracted floors win twice.

What about the supply from China?

Jefferies says it flat out: not a threat in 2026 or 2027. The tech gap is too wide. There goes the bear case for the next two years.

2028 is the year to watch closely

Big ASP fall on 15-20% new supply landing right as demand cools, and the same year China’s NAND finally catches up. The two things holding this whole thing up, tight supply and a wide China gap, both start cracking at once.

Does that mean i shouldn’t invest further into the theme? Not at all. It just tells me how to play it. The next two years are the fat part of the trade. Ride it. But this isn’t a set-it-and-forget-it hold.

The exact setup that makes memory unstoppable in 26-27 is the same one that might start showing cracks in 28, if what Jefferies is saying holds up.

Bullish memory, but as with any investment it’s worth watching closely.

Knowing when to exit is just as important as knowing when to enter.

If it really plays out like this… lol, that would be amazing.

Jefferies held an expert call with a memory consultant, and according to this expert, memory prices are expected to rise 40–50% QoQ in 3Q26, followed by another 30–40% QoQ increase in 4Q26.

This is significantly https://t.co/hgXhI7wPjG


$MU $SNDK Memory's Bull Run Just Got Louder.


Summary: Bullish AAOI on in-house laser chip moat, doubling revenue, and unpriced 3.2T roadmap despite high customer concentration risk.

$AAOI up a good % today, and it's one of the most argued-about names on the photonics layer.

People love it or hate it. A 28-year-old Texas company that spent two decades as a sleepy cable TV supplier, now one of the most fought-over names in AI interconnect.

Revenue more than doubled in a year.

I just did a deep dive, and the risk is real and so is the reward:
+They grow their own laser chips in-house while competitors wait in line for supply. The CEO calls it "complete backlog." That's the moat.

+Two customers = 82% of revenue. The single biggest risk and the single biggest strength, at the same time.

+The dilution story everyone gets wrong (it got cheaper, not worse).

+A 3.2T roadmap that is yet to be priced in.

AAOI is just how I like my stocks: High risk. High reward.

The kind of name you size according to your risk tolerance and watch every earnings call.

Bullish Photonics


Summary: Opened a long swing-trade position in AAOI at $156.47 as part of a community swing challenge.

It has been one month since I created the sub, oh it has been so much fun.

I get to use X as a personal think tank.

Most ideas are solid, some are just shit posts… we even have little birds dropping hints… Fun stuff!

Now, as the community we are, the sub is doing a swing challenge, one stock at a time.

Of course I’m not saying it’s an all in challenge since it’s a small percentage of our overall portfolio.

In the best way possible, we are sharing alpha and challenging ourselves.

The top 3 spots get a reward, if they can beat me to first place. I’m sure they will, people here are on another level.

Anyway! I’ll be sharing on the main timeline our weekly ranking.

I began the challenge today with $10,000 into $AAOI at 156.47

Let’s see how we roll ⚡
