- Is it just me, or is the list of 3 letter optical jargon never ending? We have LPO, LRO, NPO, XPO, CPO, OBO, and others for approaches. Then InP, EML, ELS, OCS, SOI, and others to add to the random terms. Even the industry events with OCP or OFC get their three letter names. People who have followed me on my optical bottleneck scavenger hunt with $SOI or $IQE might know a lot by now. But wouldn’t new followers might be super confused…
- There's a global correction right now, no clue when it stops. Kospi is down -8.18% (Sk hynix/Samsung) Nikkei is down -4.8% TWSE Index is down -3.82% As you've seen with $SOI or $RKLB dropping 30-40%. From personal experience, high beta stocks get hit a lot harder, but usually frontrun index drops. And they typically recover earlier? Aside from Korea which is typically volatile, when major indexes start correcting 3-4% a day, usually not a fun time.
- Think so. But in the meantime, I call my strategy: Diversified Losses. With $AXTI, $SOI, $AAOI, and many others. Had a massive drawdown recently, CPO exposure was hit the hardest (Foci, Msscorp, etc) and adjacent names, feels bad. Probably lesson personally, I had too much concentration in photonics vs. memory/other sectors without weighting/hedging properly. With Soitec, there's been a few negative institutional reports that I'd disagree with. Think AXT was hit harder in specific just because of float expansion/dilution concerns. AAOI, probably just brought down with the theme. I can't give advice on buying, so completely up to you to make for cost averaging or entering positions. But I do think we're still early in the Supercycle with photonics, there's bound to be corrections/crashes along the way up. If my personal thesis is correct though, many of these names will have a major inflection point in midway through 2027 scaling up to 2028. Markets don't typically wait to price things in advance, but some ideas might be a tad early or in the buildout given it's H2 2026 now. Which is why it's important to build your own conviction.
- 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.
- @carlosfagar $XFAB hasn't even been a month... I made this post saying I'd prefer if long ideas were validated on medium term timeframes, not in 3 weeks lol. $SOI is up over 175% since I shared my idea?
- Markets should be cheering on domestic champions like $AAOI. Since it's ideal to support critical AI infra from laser fab to production in the US, rather than being a bear. Feels like everyone just outsources transceivers to Asia like Malaysia or Thailand... With $INTC, $IQE, $XFAB, $MU, $WOLF, $SOI, $SIVE, and others... If you haven't noticed by now, they're all critical to US supply chains. And every one of them are getting subsidies for securing Western supply chains. Before a major trade was to short developing US/Western equities, then hedge with subsidized foreign ones. As seen with the energy/solar firms that went bankrupt, this backfired a lot on US AI infrastructure years later with the power grid. I wanted to help change this mindset, since I believe it's very positive sum to invest in building up critical Western supply chains like photonics today. Especially if $AAOI hits their $471m/month projections after reshoring their production to America. Instead of hoping they fail and calling critical nodes in the supply chains memestocks/bubbles, maybe it's good to change mindsets a bit so we don't see a repeat of the US Solar sector years later. US/EU don't just hand out subsidies or CHIPS act grants to anyone.
- 这周我自己的投资组合表现令人失望。 目前今年迄今（YTD）仅上涨了 +3,612.10%。 我在获利时会分享，但我也同样会经历大幅回撤！ 比如像 Foci/Shunsin $SOI, $AAOI 以及其他 CPO 相关标的。 如果 Alpha 足够强，不管宏观大环境如何，这些股票都应该继续涨才对… 所以对我来说，这也是一个学习的过程，需要不断微调我自己的思路，以及理解市场是如何对不同主题/供应链的各个环节进行定价的。 我只是边走边分享而已！
- @aphexinvests I’d expect $SOI, $XFAB, $IQE and others in the European supply chain to play follow the leader and recover as well. Everything got sold off with photonics / power semis recently.
- On top: $NVDA CEO also called out Silicon Photonics (optical networking) with memory. Stating that Nvidia would require “supply volumes beyond imagination”. What a bullish read through on the SiPH supply chain from $SIVE (now upstream Nvidia ecosystem) to $SOI https://t.co/m6jub4nfzx
- $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.
- @Frenchie_ They keep fighting with me with everything from $SOI, $RPI, and $SIVE. Then get embarrassed over and over. Idk if they’re going to learn
- Yeah… I think all your upstream semi supply chain companies are going much higher. Goldman now expects a combined $5.3 trillion of capex spending for the four largest hyperscalers $GOOGL / $META / MSFT / $AMZN from 2025 to 2030. Revised up from $4.5T from Q1 earnings. “Aggregate capex est. $7.6 trillion between 2026 and 2031.” And it flows upward to these tiny chokepoints like $SIVE for CPO lasers/ $SOI for Silicon Photonics substrates. Leaderdrive/Harmonic for Humanoids components. And so on… Ai names don’t move in a straight line up, but is just the beginning of the next Industrial Revolution as we move from R&D/compute buildout into commercialization from Agents -> Physical AI -> discovery.
- Europe has no chance of competing with the US regarding the AI race. But what they can do is strengthen their niche monopolies/chokepoints, and sovereign supply chain resilience. I think they're starting to realize how critical players like $SOI and $SIVE are to Europe tho. Which is why they put CPO/Photonics for AI DCs, and niche advanced packaging players on their focus policy.
- EU CHIPS Act 2.0 proposal is now released. Great news: Photonics is now confirmed to be the new structural addition to EU policy. This is thematically bullish for the EU photonics sector. Thematically: - "This new component of the Chips for Europe Initiative supports the development of photonic integrated circuits and associated technologies" - "building and strengthening advanced design, prototyping, and industrial deployment capacities for photonic integrated circuit technologies and other photonic technologies across the Union" - "extend the Union’s design capabilities, including in photonics" - "strengthen existing and develop new pilot lines and open-access semiconductor manufacturing facilities for the prototyping and production of photonic integrated circuits and associated photonic technologies - "develop and maintain design libraries and design automation tools for photonic integrated circuits, associated photonic technologies" === More specifically policy specifically focuses on -> co-packaged optics for AI data centres (CPO/interconnects focus is bullish read through for $SIVE) -> “Silicon photonics … applications in high-bandwidth data-centre interconnects…” -> Capabilities in production technologies including co-packaging and heterogeneous integration with electronic chips, manufacturing equipment, and materials platforms for photonic integrated circuits shall be strengthened ( $XFAB) -> $SOI directly mentioned in impact analysis regarding structural strengths of the EU. "The EU has a relatively strong global position in SOI wafers, with Soitec and Siltronic being notable players" -> $XFAB also directly mentioned in impact analysis, as part of creating the current funding framework. Obviously structurally positive for $XFAB since they're literally leading the European Silicon Photonics Value chain and listed in First of a Kind (FOAK) category. Initial interpretation, this is heavily positive for EU photonics leaders that go inside AI DCs as part of EU Policy. I'm expecting optical players broadly to get a tailwind from this framework. TLDR: EU photonics structurally go brrr long term. Most positive confirmation is that photonics is structurally a part of European Union policy now. We'll likely see the individual photonics names come out after this release, within 3-15 months (typically in the middle somewhere). Markets are forward looking in general.
- So $SOI and $NOK are already more established. I looked into it deeper, and the proposals were focused around 30-500M funding and revenue incentives, to bridge the pre-volume production players to HVM. $SIVE / $XFAB map to policy incentives better, but wouldn't be surprised if larger players were there.
- @StocksAREnuts Yeah I’m up like 250% on $SOI, I’m surprised markets missed the at one… Also quite surprised about $XFAB valuations given they seem to be leading Europe’s photonics supply chain development…
- @JeremieHello I genuinely didnt know $SOI had options. But even with the 17% drop today, still doing pretty well since $44 EUR. https://t.co/QQ8Mc7XvWm
- @x4tsr Yeah, well deserved victory lap that it’s now up hundreds of percent since European media kept shtting on my $SOI idea.
- Oh look, $SOI is now up 4X+ since I went long. And another 15%+ after earnings. Despite media“analysts”claiming there was nothing new with Soitec. The fact they’re trying to reorganize the company to answer demand for SOI substrates for photonics. It’s a pretty positive read-through on what’s to come for the company in the next two years. Again with companies with forward growth opportunities, it’s about looking at the future… not past earnings, unlike what some Europeans might only care about.
- Bro media… how is $XFAB a meme stock? Can you not repeat the same mistake with $RPI this time? They’re literally getting CHIPS ACT funding from the EU because of how critical they are. And have $NVDA / $NOK evaluating their SiPH side of things, while they traded at a low ~1.28 P/B. This just reminded me of $SOI low p/b but high growth verticals out of legacy segment drag. $XFAB was literally mentioned for CHIPS ACT 2 next week in the blueprints… Which focuses around photonics. The main revenue ramp was around power semis with $NVDA pushing 800 vdc. So $NVTS, $POWI, $WOLF and everyone have been taking off recently. Markets just missed $XFAB, because they’re a lesser known foundry in power semis…But US Dpt. Of commerce pointed them out as the only high volume SiC foundry in the US 2Y ago. I just happened to point out the connections. Just because you don’t understand something, don’t just go call it a “meme stock” with price detached from fundamentals.
- Idk… I mean everyone called $AXTI a scam and now it’s up thousands of percent? Everyone called $AAOI management a scam and now that’s up 7x too. Institutions went out and criticized my $SOI long as well at $44 and now it’s $170… after they bought the float… Not sure if it’s short selling or trying to accumulate the float.
- Yeah would not be surprised to see $SIVE, $SOI, and $XFAB funding with EU Chips Act 2. Glad to all my longs there (aside from $IQE) listed on the blueprint, I didn’t see that earlier in my research! Looks like formal announcement got pushed back to next week though. https://t.co/2SdG4Gocql
- @afgmantu Of course? Monopolies like $SOI don’t just disappear after they go up a few hundred percent https://t.co/dwxWwiKgXA
- @DisruptivePoltx Yeah they have close relationships with $IQE, $SOI and my other longs. Was familiar with a lot of the private photonics companies working with $XFAB so liked it a bit more.
- $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.
- 确实如此！如果你不能将整个光通信产业链脱口而出，从上游的InP（磷化铟）衬底， 路向下游直到光模块成品制造商… 那说明你读我写的东西还不够多。 不过，很高兴看到我关于 $SOI 或 $AAOI 的许多观点，能帮助大家建立起属于自己的投资信念与逻辑。
- $RPI, close to ~3x returns. Off the media branded "Meme Stock". I think after retail saw institutions bear post my thesis posts. Then ended up paper handing $AXTI, then $RPI, then $IQE, then $EWY, then $SNDK, then $AAOI, then $SOI. And them watch them all go up 3x-15x+ after institutions bought up the float. Retail finally learned not to trust them with anymore with names like $SIVE?
- @Frenchie_ lol thanks for all intros to the French community. I think the local French media complaining about my $SOI long back at $40 helped a bit too. But gotten a lot of support from France!
- 几个值得重点关注的“实质性垄断”标的: - MSSCORP (6830)：在检测和 CPO 良率把控上构筑了极深的专利护城河。 - $SOI：主导绝缘体上硅 (SOI) 衬底市场。 - NGK (5333)：稳拿薄膜铌酸锂 (TFLN) 晶圆核心技术。 - $AXTI：把控磷化铟 (InP) 衬底等上游关键材料。 像讯芯 (Shunsin) 这类公司其实很难被轻易颠覆，毕竟背靠富士康，而富士康本身就深深扎根于众多核心供应链的腹地 🏭 $SIVE 的逻辑也极其相似。他们已经成功打入 (design in) 了众多顶尖 CPO 架构的设计体系，抱紧了 Ayar、Lightelligence (壁仞的供应商)、Lightmatter 以及 Celestial 等 众行业领军者的大腿 相比之下，个人认为 $HIMX (奇景光电) 或 Foci (上诠) 未来面临被踢出局 (design out) 的风险最大，很有可能会被台积电的光学部门采钰 (Visera 6789) 这类巨头直接垂直整合。不过话说回来，在未来两三年内，借助 CPO 相关的光纤阵列 (FAU) 和无源器件，他们眼前依然有 波巨大的赚钱机遇
- AI capex spend is expected to go to "$3 to $4 trillion annually" by 2030 from $NVDA Jensen Huang projections. You're not bullish enough. And it might be a good idea to stay exposed + own the keys of the AI Kingdom: -> $AXTI controls the materials buildout with photonics. -> $SOI controls the AI buildout with silicon photonics. -> $SIVE controls laser chokepoints for CPO. -> $IQE controls Western epiwafer supply chains for photonics. All these started off as tiny companies, yet the trillions of projected capex gradually upward to them. There's many more in other industries as well. -> AI Capex flows to Neoclouds like $NBIS. -> AI Capex flows to memory like $MU and $SNDK. And many of the "commodity" materials or "science projects" for the past 20 years now a sudden shift in exponential TAM expansion. We're witnessing the next industrial revolution with Artificial Intelligence + Physical AI.
- @ncs1912 Because I care more about novel ideas and if they get validated in markets. If someone with $4000 had a great idea about $SOI before anyone else found it. Then Soitec goes up 4x. That's more valuable to me/others than if someone with a large account $10M off a 1% return.
- European quantum/optical/glass chokepoints go BRRR? $ALRIB +8.35% $LPK +3.21% $IQE +5.68% $SOI +4.98% As a side thought, it’s a nice vote of confidence to retail that the LPKF CEO bought shares off the market. More CEOs should do the same, even if it’s small. https://t.co/BwxBnd2wDm
- Am I that popular? I did get a lot of dm requests to manage their capital recently. But only here to help out regular retail investors succeed on their own with ideas like $SIVE or $SOI. I feel like anything else would be a bit of a distraction.
Ongoing takes on other optical names too
