- OpenLight (private) seems to get bigger and bigger every time I look at it. If you’re curious about their public ecosystem outside of Advantest: $JBL ( $SIVE partner ) for scaling PICs $MRVL and $MXL for DSPs $TSEM for the foundry. $300394.SZ / TFC Optical (OSAT/subassembly) Can often get exposure into private growth through public equities if you’re not an accredited investor. Since optical players look very interconnected.
- Curious if anyone's portfolio is green after today's fun day. $KORU: -32.06% $SOXL: -22.98% $IQE: -13.58% $DRAM: -12.6% $AXTI: -12.57% $FLNC: -12.5% $AAOI: -11.2% $SIVE: -11.7% $TSEM: -10.24% $SNDK: -12.5% $MU: -11.8% Sk Hynix: -12.35% Samsung: -9.6% $MRVL: -8.3% $LITE: -7.6% $SOI -7.15% $TSM: -6.1% $AMD: -6.04% Feels like anything high-beta or semis had a steep drop.
- Wow, $TSEM up 10%+ today. Good times, should have made this one of my largest positions in hindsight back in March. Foundries like $GFS and $INTC have been going brrr lately. https://t.co/m5KVJ8vOAS
- So short term ramp, I see $LPK probably might be more parabolic. Since when equipment suppliers switch from qualification to volume production as seen with $AEHR or $AIXA recently, they tend to get re-rated to $3-7B MCs. But 99% are structurally more capped on where they head. Long term, I personally see $XFAB has much much higher upside if they're able able to lead European's photonic supply chains and build out a $TSEM alternative with MTP. But are earlier on in the process.
- Wow, $IQE and $TSEM sign a multi year InP epiwafer deal. Remember I told you all IQE was important to Western optical supply chains back at $12? $MTSI had to go out of their way to secure their supply with IQE. Now there’s another critical deal with Tower Semi. https://t.co/4A5PAuA3PU
- Why do I keep getting these questions!!! $XFAB is building a Silicon Photonics foundry alternative to $TSEM and $GFS. And has Europe backing it + $NVDA evaluations. It takes time... Like October 2026, should finish up development. Then 2027 production scaled into 2028 (mass production), since they've been working on it since 2023. Everyone thinks it’s a depressed automaker supplier right now. And thankfully with European names they tend to look at TTM revenue over forward growth. So somehow it’s leading EU’s efforts to create a $TSEM silicon photonics foundry + supply chain at ~€1.1B MC? That R&D directors from ASE cite + others as future CPO routes. I’m might just really early to a lot of things, but of course most of the risk/reward comes from taking a little leap of faith in seeing it commercialized. Otherwise people can take the de-risked route with Tower directly (which I also wrote a thesis on awhile back and also like).
- $SIVE is #1, $AAOI is #2 used wrong wording above. Generally a fan of: - $SIVE (CPO lasers) - $AAOI (End-to-End pluggable/cpo) - Foci (FAU +passive components $TSM COUPE / $NVDA) - Shunsin (Packaging/Test) - Win Semi (foundry) - $TSEM (foundry) - $SOI (silicon photonics) - Nextronics (CPO connector / cage thermal module) And a few others.
- @Jornka329996 Are you high, I posted about $XFAB this week. Their silicon photonics platform with $NVDA and $NOK scales h2 2027 / 2028. I think it’s a heavily derisked precommercial long that looks like the next $TSEM. With upside from SiC/GaN. Just needs time.
- Tbh $XFAB lowkey reminds me of early $TSEM. Just sub <$2B MC. You basically never find a company with $NVDA and $NOK actively validating your pre-commercial silicon photonics foundry… (photonixFAB) While getting CHIPS act/Gov grants to subsidize capex. While leading the Europe’s effort to build a photonics supply chain. Feels like that alone would justify valuations… but you get the power semi SiC/GaN operations for free too and all its assets. CHIPS act 2 is coming out tomorrow, and $XFAB is listed in the photonics blueprints. Did I miss something? Or did markets miss something?
- $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.
- Wow, 400,000 followers! Thank you everyone. I find it fun to share ideas with everyone for free from $TSEM to $AAOI. And especially if they end up directionally right + help others build their own conviction. https://t.co/DeEnV6SAkq
