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。

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?

梳理AI半导体供应链瓶颈，看好存储、光子及台积电，指出中游为定价关键。
以下是我对 Semivision 瓶颈总结的 TLDR（太长不看版）及其映射到投资框架的内容： HBM（高带宽内存）： HBM4 (16Hi) - 三星，SK 海力士，$MU HBF（高带宽闪存）- $SNDK，Kioxia Base Die（基础晶圆）- $TSM，三星（内部） CPO（共封装光学）/光子学： 玻璃基板：$GLW，$INTC，Ibiden 光学：$LITE，$AVGO，$COHR，$MRVL 电力传输： 电压：$MPWR，$VICR 散热：$VRT，$NVT，$MOD 电网：$ETN，$SBGSY SiC/GaN（碳化硅/氮化镓）：$ON，$IFNNY 机架：$APH N2 产能： $TSM，$AMD（数据中心先行者），$QLCM，联发科，$NVDA 先进封装： 良率：$CAMT，$ONTO，$KLAC OSATs（外包半导体组装与测试）：$AMKR $BESIY，Disco Semivision 的总结： 1. “先进封装产能与良率控制” 2. “HBM 生态系统协调” 3. “电力传输创新（SiC、GaN PMICs、机架级电源架构）” 4. “CPO/光子学集成能力” 5. “数据中心基础设施作为半导体收入实现的‘隐性限制因素’” 正如你可能知道的，我对上述的存储/光子学领域（如 SK 海力士/三星，$SNDK，$MU，$LITE）以及 $TSM 最为看好。 我可能会稍微向上游延伸，比如 $AXTI（磷化铟前驱体），但中游玩家是瓶颈所在，并掌控大部分定价权。 但为了简化普通散户投资者的理解，我添加了相关公司的评论。

Here's my TLDR + mapped into investment framework from Semivision bottleneck summary: HBM: HBM4 (16Hi) - Samsung, Sk Hynix, $MU HBF - $SNDK, Kioxia Base Die - $TSM, Samsung (internal) CPO/photonics; Glass Substrate: $GLW, $INTC, Ibiden Optical: $LITE, $AVGO, $COHR, $MRVL Power Delivery: Volatage: $MPWR, $VICR Thermal: $VRT, $NVT, $MOD Grid: $ETN, $SBGSY SiC/GaN: $ON, $IFNNY Rack: $APH N2 Volume: $TSM , $AMD (First mover dc), $QLCM, Mediatek, $NVDA Advanced Packaging: Yield: $CAMT, $ONTO, $KLAC OSATs: $AMKR $BESIY, Disco Semivision's summary: 1. "advanced packaging capacity and yield control" 2. "HBM ecosystem coordination" 3. "power delivery innovation (SiC, GaN PMICs, rack-level power architectures)" 4. "CPO/photonics integration capability" 5. "data center infrastructure as a “hidden limiter” to semiconductor revenue realization" As you probably know, I'm probably most bullish on memory/photonics like Sk Hynix/Samsung, $SNDK, $MU, $LITE above. And $TSM. I probably go a bit more upstream like $AXTI for InP precursors, but midstream players are the chokepoint + control most of the pricing. But just added commentary of related companies to topics to make things simpler for the regular retail investor.

分析VRT受益于AI基建电力瓶颈，认为其将跑赢大盘，NVT风险回报更优。
哈哈，关于股票代码的评论太多了，无法一一回复。关于 $VRT，它是数据中心建设的高贝塔敞口。Q3 营收 26 亿美元，同比增长 29%，指引 FY 中值为 102 亿美元。整体利润率增长，例如 Q3 调整后营业利润增长 43% 至 5.96 亿美元。后者可能表明，由于电力基础设施组件严重短缺和电网容量限制，其拥有类似内存行业的定价权。 $NVT 在当前市值下（24.5 倍 EV/EBITDA，对比 33 倍）可能具有更好的风险调整后回报。但除此之外，能源并非我的专业领域，因此我无法像对 neoclouds 或金融科技那样提供详细细致的观点。 不过，我可以说 Vertiv 在 AI 基础设施建设和电力供应约束的背景下，凭借其角色（例如与 nvda 合作的冷却和 800vdc 电力），方向上应该会跑赢大盘。
英文原文
lol there's a lot of ticker comments, can't respond to every one. So for $VRT it's a high beta exposure to DC buildout, from Q3 earnings $2.6B revenue 29% y/y, guided FY $10.2B midpoint, overall margins grew eg. adjusted operating profit increased 43% to $596 million in Q3. The latter probably indicates better pricing power like memory sector from a severe shortage of power infrastructure components and grid capacity limitations. $NVT might be better risk-adjusted return at current marketcaps (24.5x EV/EBITDA), vs. 33x. But that aside, energy not my field of expertise so I can't give detailed nuanced opinions like neoclouds or fintech. However, I can probably say Vertiv directionally should be outperform due to backdrop of AI infra buildout + power supply constraints and it's role (eg. cooling, 800vdc power that they're doing with nvda)
