Names like: - $ASX - Sumitomo Electric - $JBL - $VICR - $GFS - $AAOI - AlChip - $TSEM - $FN - Furukawa Electric - $CLS - $NBIS - $NOK - $AMKR - $LITE - $COHR 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.
