Off the top of my head.
So basically, AI exposure trading in the $10-100B range.
Likely have compelling ROI right now compared to indexes or $ARM to $MRVL that ran quite a bit?
(Just a disclosure, only have financial interest in NBIS/TSEM/AAOI above)
I mention a lot of smaller ideas, but that’s just to chase outsized returns.
Still feels like many of these have room to go.

@RockyKh49376975 I ended up buying $IBIT and $ETHA today at $62K / $1.75K.
Just swing trading those, not long term holding.
But prices dropping hurts $HOOD / $COIN and the others.

Can’t believe $ARM went straight from $134 to $354 when I took positions.
The ~$15B annual revenue coming from these cool name AI CPUs seemed a bit insane at the time.
At Computex, looks like $NVDA is unveiling new ARM based processors too.
Counterpoint them shows them dominating AI ASIC servers by 2029, projections which is crazy…
GPU:CPU ratios are requiring more and more CPUs.
Seems like they have everything going for them?

Holy crap… My $EWY 2028 leaps are now up 428%+.
So 5.2x ROI trade, in 3 months.
Thats what happens when IV increases and underlying memory assets in SK Hynix / Samsung also appreciate. https://t.co/XdE21DOyoz https://t.co/bOADobOLLx

$SIVE is the most compelling CPO/photonics exposure to me.
Addressing the disinformation: I haven’t sold and don’t plan to sell a single share.
I do think this ends up the next $80B+ $LITE one day from ~$2.1B.
And I personally have plans to acquire more ownership + support their M&A prospects.
I believe earnings transcripts will be strongly positive.
As in the part few months we’ve discovered:
> AlChip/Amazon private placements, which is positive for Ayar -> $SIVE implying Trainium 4 design in
> Wiwynn + Ayar CPO scale up
> $JBL 1.6T optical transceiver ramp with Sivers incoming faster than markets expected (with relatively dramatic moat + demand as much as they can produce)
> O-Net scaling up ELS efforts with $SIVE
> $YSS acquisition of $SIVE allspace lead partner, designing Sivers into Space defense primes
> New CHIPS ACT funding for $SIVE
> $POET H2 volume ramp and their new $50m -> $500m order (with $SIVE as light source)
> information discovery around $AAPL using $SIVE lasers for next gen consumer devices
> information discovery around links to Lightelligence (went public $10B+ MC) + Lightmatter as likely customers.
> Celestial volume ramp with $MRVL indicators.
> new customers working on TFLN with $SIVE like Lightium
> $AMD going with $GFS for CPO, and GFS listing sivers as one of two laser suppliers
> Ayar removing $MTSI / $LITE from their website and signaling $SIVE as primary source/sole source
> Ayar raising $500m for volume ramp (intel, Mediatek, Nvidia, amd etc)
> pluggable TAM expansion signaled from 2025 annual report
> Nasdaq listing expected soon
> MSCI small cap index / Nasdaq omx inclusion, making Blackrock, Vanguard and others passive buyers
> M&A signaled from 2025 annual report + 2 new board members that have experience in that area
> $NOK as likely customer from 2025 annual report.
> $LITE getting cw bottlenecked from EML contracts, $SIVE signaling capacity agreements in place with Win, making the a likely bottleneck owner + chokepoint in CPO sector.
All of this market research was done before earnings.
Any results is just confirmation of supply chain mapping done.
I don’t think anyone cares about former quarter revenue since $SIVE is an exceptionally compelling 2027 long, especially H2 onward.
Only thing I’m looking at are:
> TAM expansion of the overall photonics supercycle (eg. optical engine, ELS, pluggables) either from M&A or developments
> volume ramp expectations from existing companies
> Nasdaq listing timelines for more liquidity to support their M&A efforts
> any new customers signaled for CPO/Pluggables

I mean all my European longs from $SOI, $IQE, $RPI, $SIVE, $ALRIB followed this trend if we just look at chart.
Long term they’ve all ended up directionally right, and now they’re all up hundreds of percent.
I don’t control or trade volatility with $XFAB, but interested in being a part of their long term growth vectors with power semis/photonics.

Back when $AAOI was ~$20-30 when I went long:
I thought $AMZN and $MSFT were qualifying specific optical transceivers for their ASIC programs.
Turns out it’s more interchangeable/mass producible.
Regardless, glad my thesis on $LITE, $AAOI, Innolight, $COHR, $AXTI played out so well.
Keep in mind: everyone on X was saying “scam management” with $AAOI back at $20-30…
Or “scam company” with $AXTI at $12.
FUD was pretty extreme.
Feels like dejavu again… going long on the next CPO architectural shift like $SIVE or Foci? And getting the same comments.
We’ll see if my CPO longs play out the same way like Shunsin does with Innolight or $SIVE does with $LITE.
Either way all of those are now up hundreds to thousands of percent.

$XFAB (photonics + power semis) is an interesting long idea at $1.28B MC, that I took positions in.
Given EU CHIPS act 2 is today as the catalyst for European photonics players.
> 800 VDC power semi exposure to $NVDA push through $NVTS + $POWI
> Silicon Photonics / CPO exposure with $NVDA as evaluation stage for high volume manufacturing (optical transceivers/switches)
> The only high-volume SiC foundry in the US.
> One of the critical MEMS foundries
> ~1.29 P/B, which was around what $SOI was sitting at when I went long. Depressed valuations due to legacy drag
> ~6.5-8.5 fwd p/e 2028 personal est.
> backstopped by Government:
- EU CHIPS act, $128M Euros
- US CHIPS act $50M PMT (department of commerce).
With likely more coming (just signals critical importance to Western supply chains).
So at a certain point with all the grants, they’re just getting the capex funded by the Governments.
EU CHIPS act 2 is coming out this week, and I’m gonna go ahead and guess $XFAB might get included given they were before, and this package is specifically targeting photonics.
~$1.3B MC seems compelling to me if it can pull a Soitec reversal (low p/b, very high growth segments, auto legacy drag).
As for the $NVDA silicon photonics relationships it’s under “photonixFAB”.
Markets probably missed this silicon photonics relationship (like $TSEM when I went long) with Nvidia since XFab leads this… Just under a different name.
For power semis, XFAB is named for SiC + $NVTS. In PCN-22181, $POWI explicitly names XFAB as its foundry.
Given its exposure to power semis and photonics as growth, low P/B, gov backstop (of course dyor, just sharing my personal thoughts)
Thought it personally seemed compelling.
