分享周末研究的热管理和功率半导体供应链主题股票清单
随便分享一些我周末研究的随机主题： -> 功率半导体、集成电压调节器、多相控制器、CDU、冷板、歧管、泵、阀门、热交换器、背门系统、冷水机。 $POWL、$NVT、010120 KS、267260 KS、2308 TT、$VICR、$POWI、宁德时代、阳光电源 300274 C -> 热管理相关（ALFA SS、ASTK DC、大金 6367 JP）、$CARR、MTRS SS） 这些只是我之前聊过的之外的一些，比如 $NVTS 或 $HPS.A。 它们都有点已经被定价了，但现在是个好的起点，可以帮你找到那些还没被定价的更重要玩家。 然后你会问：这些产品最有可能依赖哪一家公司？ 我个人对能源/散热/电力这个交易领域不太熟悉，我很高兴承认这一点，因为一切都是学习的过程。 但通常即使我发现了一些有趣的东西，我也觉得它不如继续持有CPO多头更有说服力。学习更多总是很有趣的。 一直在寻找SRAM相关的敞口，我觉得私募市场比 $CBRS 更好。
英文原文
Just random themes im looking im having a good time looking into over the weekend: -> power semis, integrated voltage regulators, multiphase controllers, CDUs, cold plates, manifolds, pumps, valves, heat exchangers, rear-door systems, chillers. $POWL, $NVT, 010120 KS, 267260 KS, 2308 TT, $VICR, $POWI , CATL, Sungrow 300274 C -> thermal stuff (ALFA SS, ASTK DC, Daikin 6367 JP), $CARR, MTRS SS) These are just ones aside from the ones I've talked about eg. $NVTS or $HPS.A. They're all kinda more priced in but now but it's a good starting point in terms of finding more important players that's not priced in. Then you try and look: which single company do most of these probably rely on? I'm personally less familiar with the energy/cooling/power trade, which I'm happy to admit since everything is a learning process. But normally even if I find something interesting, i don't find it more compelling than staying in CPO longs. Always it's always fun learning more. Was always looking for SRAM-adjacent exposure, think private markets are better to go then $CBRS?

AI 相关供应链全面拥堵
最近新闻和瓶颈的 TLDR，全部都在起飞： 1. CPU 瓶颈 - $INTC CEO 说 AI 推理把 CPU 比例从 1:8 推到了 1:1。 CPU 起飞（$AMD、Intel、$ARM）-> $AMAT / $TSM / $KLAC 等也跟着起飞。 2. PGME / PGMEA 短缺。DuPont、Shiny Chemical、Daxin、San Fu、$DOW 等都要起飞？ 光刻胶瓶颈也起飞？ 3. 微控制器潜在瓶颈 + 涨价（Arterytek / Arterychip）正在压缩 AI 产能。 MCU 公司可能也要起飞？ 4. 总统本周援引了《国防生产法》，里面包括： - 变压器 - 输电组件 - 先进导体 - 电力电子 - 变电站 - 高压断路器 - 保护继电器、 电容组 - 电气硅钢 这些都被称为“严重短缺”。像 $AMSC、$PLPC、$POWL、$VICR、$ATKR、$HPS.A 之类的也要起飞。 5. $GOOGL 在扩容新的 TPU 服务器。谷歌把 AI 芯片拆成训练 TPU 和推理 TPU。 台湾很开心。联发科等也要起飞？ 6. 三星、Kingston 把 SSD 价格上调了 10% 以上。 SSD 价格还会继续起飞？ 7. T-玻璃玻纤短缺还在恶化？Nittobo 等也继续起飞？ 8. 用于蚀刻电路和阻燃的关键材料溴，价格已经涨到每公吨 12,000 美元。 以色列的 ICL Group 似乎掌控了全球 40% 的供应？ 我对这个不算特别熟，但也有点可疑的起飞？ 9. “外延厂 Landmark Optoelectronics 报告称产量仍远低于客户需求”。 嗯 $IQE 和其他公司也要起飞？ 10. “AI 数据中心碰到互连限制，正在推高光模块需求”。“瓶颈不再只是算力，而是算力如何连接。” 来自 $AAOI、$LITE、$COHR、Innolight 等的光子链条继续起飞？下一代来自 $SIVE、$POET、$MRVL、Win Semi 等也起飞？ 基本上就是 AI 半导体供应链全面起飞，因为 AI 超大规模云厂商需求带来了到处都是的短缺。
英文原文
TLDR of recent news + bottlenecks that go brr: 1. CPU bottleneck - $INTC CEO said AI inference pushed CPU Ratio From 1:8 to 1:1. CPUs go brr ( $AMD, Intel, $ARM) -> $AMAT / $TSM / $KLAC, etc. go brr. 2. PGME / PGMEA shortage. DuPont, Shiny Chemical, Daxin, San Fu, $DOW and others go brr? Photoresist bottleneck go brr? 3. Microcontroller potential bottleneck + price hikes (Arterytek/Arterychip) was weighing price hikes on AI capacity squeezes. MCU companies potentially go brr? 4. President invoked the "Defense Production Act" this week, it included: -Transformers - transmission components - advanced conductors - power electronics - substations - high-voltage circuit breakers - protective relays, capacitor banks - electrical core steel As "severe shortages". Stuff like $AMSC, $PLPC, $POWL, $VICR, $ATKR, $HPS.A go brr. 5. $GOOGL ramps new TPU servers. Google splits AI chips into training and inference TPUs. Taiwan happy. Mediatek and others go brr? 6. Samsung, Kingston lift SSD prices by over 10%. SSD prices keep going brrr? 7. T-glass fiberglass shortages keep getting worse? Nittobo and others keep going brrr? 8. Bromine, essential for etching circuits and flame retardancy, has surged to $12,000 per metric ton. ICL Group in Israel apparently controls 40% of the global supply? Not as familiar with this but questionable brrr? 9. "Epitaxy manufacturer LandMark Optoelectronics reporting output still far below customer needs". Uhh $IQE and others go brr? 10. "AI data centers hit interconnect limits, boosting optical module demand". "the bottleneck is no longer computing power alone, but how that power is connected." Photonics from $AAOI, $LITE, $COHR, Innolight and others keep going brr? next gen from $SIVE, $POET, $MRVL, Win Semi and others go brr? Basically AI semi supply chains go brr because there's widespread shortages everywhere due to AI hyperscaler demand.

两周等权收益回顾
先放这儿…… 如果等权计算，两周回报会是 +15.02%。 在 30 只不同股票上……大多是中大盘。 1. $INTC +29.62% 2. $MRVL +40.95% 3. $TSM +4.72% 4. $COHR +18.9% 5. $RKLB +26.76% 6. $DRAM +12.29% 7. $AVGO +18.32% 8. $AMZN +9.17% 9. $ARM +36.6% 10. $TSEM -1.25% 11. $IBIT +7.68% 12. $NBIS +15.22% 13. $GOOGL +6.41% 14. $AMKR +32.25% 15. $HOOD +19.14% 16. $CRCL +17.58% 17. $META +4.9% 18. $LITE -5.28% 19. $LPTH +20.23% 20. $FN +11.54% 21. $JBL +15.45% 22. $MP +17.48% 23. $HIMS +42.53% 24. $SMTC +18.83% 25. $POWL +9.26% 26. $VPG +17.44% 27. $MOG.A -3.96% 28. $MSFT +11.44% 29. $CVX -1.47% 30. $XLU -2.29% 显然时间周期很短，但我预计这些里面很多还会继续上涨。 如果你在特定名字的下跌时点位进场，而不是一口气同时做多，结果可能会更高。 也不算差吧？
英文原文
Just putting out there... Would have been +15.02% in 2W equal-weighted return. On 30 different stocks... mostly medium-large cap. 1. $INTC +29.62% 2. $MRVL +40.95% 3. $TSM +4.72% 4. $COHR +18.9% 5. $RKLB +26.76% 6. $DRAM +12.29% 7. $AVGO +18.32% 8. $AMZN +9.17% 9. $ARM +36.6% 10. $TSEM -1.25% 11. $IBIT +7.68% 12. $NBIS +15.22% 13. $GOOGL +6.41% 14. $AMKR +32.25% 15. $HOOD +19.14% 16. $CRCL +17.58% 17. $META +4.9% 18. $LITE -5.28% 19. $LPTH +20.23% 20. $FN +11.54% 21. $JBL +15.45% 22. $MP +17.48% 23. $HIMS +42.53% 24. $SMTC +18.83% 25. $POWL +9.26% 26. $VPG +17.44% 27. $MOG.A -3.96% 28. $MSFT +11.44% 29. $CVX -1.47% 30. $XLU -2.29% Obviously short timeframe, but I expect many of these to keep going up more. And probably would have been higher if you time the drop on specific names, rather than going long all at once. Not too shabby?

DPA 受益者清单
是的。总统在两天前援引了“国防生产法”。 这是为了扩张本土基础设施。 隐含受益者包括： 输电和先进导体： $AMSC - HTS 线材（先进导体）、电力电子 $PLPC - 先进导体 $ATKR - 输电组件 $VMI - 电网组件 电力电子 $AEIS - 电力控制电子 $VICR - 电力传输 电容组 $VSH - 电力电容和电容组 变电站和高压断路器 $POWL - 变电站 / 开关设备 $AZZ - 变电站 变压器 $HPS.A - 我最喜欢的变压器标的 $SPXC - 电力变压器 电工核心钢 $CLF - 美国唯一的电工钢生产商？ 这里面包括： - 变压器 - 输电组件 - 先进导体 - 电力电子 - 变电站 - 高压断路器 - 保护继电器、电容组 - 电工核心钢 TLDR：这项行政行动宣布了关于电网基础设施本土供应链的国家能源紧急状态。它授权联邦资金、采购承诺和加速措施，以迅速扩产。 受益者很多，我把 $AMSC、$CLF、$PLPC、还有 $HPS.A 组成了一个迷你 ETF；其他的我没持有。 我猜接下来 3 到 6 个月会有一堆 DOE 合同，比如“DoE 奖励 ___ 给 $POWL”之类的。
英文原文
Yes. The President invoked the "Defense Production Act" 2 days ago. To expand on domestic infra. Implicit beneficiaries were: Transmission & Advanced Conductors: $AMSC - HTS Wires (advanced conductors), power electronics $PLPC - advanced conductors $ATKR - transmission components $VMI - grid components Power Electronics $AEIS - power control electronics $VICR - power delivery Capacitor Banks $VSH - power capacitors and capacitor banks Substations & High-Voltage Circuit Breakers $POWL - substations/switchgear $AZZ - substations Transformers $HPS.A - My favorite for transformers $SPXC - power transformers Electrical Core Steel $CLF - Only producer of electrical steel in America? This included: -Transformers - transmission components - advanced conductors - power electronics - substations - high-voltage circuit breakers - protective relays, capacitor banks - electrical core steel TLDR: The executive action declared a national energy emergency regarding the domestic supply chain for grid infrastructure. Authorized federal funding, purchase commitments, and expedited actions to rapidly expand the manufacturing. Lot of beneficiaries, I made a mini ETF of with $AMSC, $CLF, $PLPC, and then $HPS.A; dont have any of the others. There's probably going to be a bunch of DOE contracts in the next 3-6 months like " DoE Awards ___ to $POWL " off this act is my guess.

认为变压器 / 开关设备是 DC 瓶颈，需求和 backlog 都很强。
遗憾的是，我的票并不是每周都能翻三位数。 $HPS.A 目前也就涨了大约 17%。 Hammond 是我在变压器 / 开关设备这个 DC 瓶颈上的选择，因为它市值更低，但在干式变压器市场的份额很高。 $POWL 也是我经常遇到的另一只不错的开关设备多头；我最后没有买，但还是顺手提一下。 变压器 / 开关设备大概被低估了，作为瓶颈很重要，但很多型号未来 2 到 5 年都已经卖光了。 也正因为如此，它们正在造成大范围的 DC 延迟，而从 backlog 可见度和极端需求来看，这些标的应该会是不错的结构性多头。
英文原文
Unfortunately, not all my names go up triple digits in a week. $HPS.A is only up ~17% so far. Hammond was my pick for the transformers/switchgear DC bottleneck since it had a lower MC but high dry transformer market share. $POWL was another good switchgear long that I came across often; I ended up passing but just throwing that out there. Transformers/Switchgear are probably under-appreciated as a bottleneck but many types are sold out for the next 2-5 years. Because of this, they’re causing widespread DC delays and should be a good structural long from backlog visibility + extreme demand.

英文原文
Here's a bunch of random 30 US-available random stocks I like today and why: 1. $INTC - America's hope for foundry, national security 2. $MRVL - scales rev from future maia asics and add ons like cpo, they do everything lost count 3. $TSM - backbone of semis/ai 4. $COHR - They do everything vertically integrated + captures optical cycle 5. $RKLB - the final frontier of space will be around 5 years from now and 20 years from now. 6. $DRAM - memory exposure for samsung/sk hynix 7. $AVGO - hyperscalers dont like nvidia gpu tax 8. $AMZN - nobody can compete against the overnight shipping of toilet paper. robotics will lower opex over time 9. $ARM - AGI CPUs scale revenue quite a bit over the next decade 10. $TSEM - you're going to need a foundry for light based stuff 11. $IBIT - bitcoin, we all know by now 12. $NBIS - i think it's the next AWS. Also they do self-driving cars with uber, own scaling DB companies, data labeling. It's almost like a mini Google. 13. $GOOGL - youtube is not going away, gemini is great. they're vertically integrated with TPUs and fund buildout with operating income so i like it. 14. $AMKR - super facilities coming online in late 2027-2028. benefits from made in america 15. $HOOD - i dont like short term, but long term i'm a fan of Robinhood since they captured retail + have more products like banking, etc that they're scaling up. product innovation is wild. 16. $CRCL - I happen to really like stablecoins and see them as the future for both payments/holding (depends on clarity act) 17. $META - people aren't going to stop using instagram or whatsapp, or others anytime soon. 18. $LITE - $GOOGL TPU exposure decently high part of BOM. As long as Google's AI program keeps running I think $LITE will do well. 19. $LPTH - Germanium and China export controls will always be an issue so US made engineered alternatives will always be important 20. $FN - Someone needs to assemble optical stuff 21. $JBL - same as above, but added with ip from Intel's SiPh acqusition so might end up like innolight? 22. $MP - American rare earths program is extremely important, similar to $INTC national security risks 23. $HIMS - Okay here me out they just acquired a ton of companies, and at $19 they have global DTC channel. short sellers really hate this company, but I think it's actually promising as a contrarian long 24. $SMTC - LRO/LPO transition 25. $POWL - US alternative to hammond for switchgear DC type bottleneck 26. $VPG - Humanoids will be a thing down the road maybe 2027-2028, this makes the sensors. 27. $MOG.A - Feels like i see them everywhere in robotics, to spacex supply chains 28. $MSFT - At $375, one day we'll look back and see this as a buying opportunity. 29. $CVX - oil might crash after war but these oil companies are going to be extremely important, especially when Venezulea is a goldmine. 30. $XLU - i think rate cuts might be back online, we need power/grid for AI so these names will always be improtant from $CEG to $NEE Just throwing out other thoughts aside from $AAOI and $AEHR.
