  1. 杂谈

    夸赞对方的日文投资博客很有名。

    @pennyhunter_sub 那个有名投资者的博客是什么!我想读读看!

    英文原文

    @pennyhunter_sub 有名な投資家のブログって何!読んでみたい!

  2. 方法论 $AXTI

    说对高税的办法就是赚得更多。

    @miraclemaster07 对,税确实高。不过我的理念就是把短期资本利得税赚回来。 如果你赚了 20 倍,又被征 50% 的税,你最后还是能赚到原始投入的 10 倍。 如果你一直拿着同一笔多头,而它只涨 20%,那反而更差。

    英文原文

    @miraclemaster07 Yeah unfortunately taxes are high. But my philosophy is just outearn short term capital gains tax. If you make 20 times and get taxed 50% you still make 10 times your original investment. If you stay in the same long and it just goes up 20% that's worse.

  3. 供应链分析 $AXTI

    指出 Nippon Chemical 是 photonics AI 供应链关键材料商。

    @Jornka329996 哦,那家是 Nippon Chemical Industries,市值 1.69 亿美元;如果把它打掉,整个 photonics 方向的 AI buildout 都会被扰乱。 因为它是生产 InP 衬底所需红磷的第一供应商,而这些衬底又要用在 $AXTI、Sumitomo 和 JX 里。

    英文原文

    @Jornka329996 Oh it was Nippon Chemical Industries at $169m, if you take down that company it disrupts the entire AI buildout with photonics. Since its the #1 supplier of red phosphorus needed to make inp substrates at $AXTI, Sumitomo, and JX.

  4. 杂谈

    说自己都公开发出来了。

    @Smith18000 没有,我都是公开发的。

    英文原文

    @Smith18000 Nah I post them all publicly

  5. 业绩复盘 $RPI$AAOI$LITE

    说 RPI 两个月后盘中翻倍,证明自己的 AI 硬件 thesis。

    $RPI 今天盘中已经涨到三位数回报了,才两个月。 这说明我年内已经从 $AAOI 到 $LITE,命中了 14 只涨幅 100%+ 的股票。 如果我能在很短时间内写出 14 篇分别对应不同多头、而且它们都翻倍的 thesis……也许我确实还行? 我最早把它定义成 AI agentic hardware orchestration。 但二月份的时候大家都把我的 thesis 叫成“meme”。 (特别感谢 FT、Reuters、Bloomberg) 不过我当时就指出了营收加速,预计会比共识高出 3 倍。财报也验证了我的估计。 现在它正在被重新定价成一家 AI 硬件公司。

    英文原文

    $RPI hit triple digit % return intraday today, just 2 months later. That’s 14 different stocks I’ve called YTD from $AAOI to $LITE that hit 100%+ returns. Maybe if I’m able to write a thesis on 14 separate longs that double in a short time period… I’m decent at it? I was the first person to long it as AI agentic hardware orchestration. But everyone called my thesis a "Meme" back in Feb. (Special S/O to FT, Reuters, Bloomberg) But I called out revenue acceleration expecting a 3x beat compared to consensus. And their earnings report validated my estimates. It's now being re-rated as an AI hardware company.

  6. 方法论

    说自己不搞高价门槛,因为觉得市场里就能赚回来。

    @SosaKayser666 我很清楚很多人甚至愿意每月付 30 美元。 但我还是把最低价定在 1 美元,因为我相信我的想法足够好,我完全可以靠市场里的收益赚回来。 而且我不认同把信息 / 标的搞成门槛。

    英文原文

    @SosaKayser666 I’m well aware a lot of people would even pay $30/month. But I charge $1 as bare minimum since I believe my ideas are good enough that I can make all my returns in the market. And I don’t believe in gatekeeping information/names.

  7. 方法论

    说自己是在尽力帮助散户,分享信息发现。

    我是真的在尽力帮散户投资者! 股票是正和游戏,所以我相信最好的帮助方式就是把信息发现 / 综合整理分享出来。 是啊……很多收费给自己选股的人,半数时候根本不知道自己在说什么。

    英文原文

    I’m genuinely trying my best to help out retail investors! Stocks are positive sum so I do believe the best benefit is just distributing any information discovery/synthesis. Yeah… lot of the people charging money for their picks don’t know what they’re talking about half the time.

  8. 杂谈

    感谢对方帮自己开始用 X。

    @pepemoonboy 谢谢你帮我开始用 X。我一直都很感激你!

    英文原文

    @pepemoonboy Thanks for helping me get started on X. Always grateful to you!

  9. 杂谈

    说今天变化不大。

    @mcMG_2137 不幸的是,今天没什么重大变化。 https://t.co/f34jFERIl8

    英文原文

    @mcMG_2137 Unfortunately not much of a major change today. https://t.co/f34jFERIl8

  10. 杂谈

    感叹好像大家都在看自己的帖子。

    wtf。为什么感觉 X 上每个人都在读我的帖子了? https://t.co/bdvL9bvBfE

    英文原文

    wtf. why does it feel like everyone on X is reading my posts now? https://t.co/bdvL9bvBfE

  11. 方法论

    认可对方关于数据源的纠正。

    @iamfabian 谢谢,如果真是这样,这就是一个重要的纠正,我会再深入看看。 Digitimes 通常算是比较靠谱的来源。 https://t.co/yDUu8XFWtF

    英文原文

    @iamfabian Thanks this is an important correction then if true, will look into it more. Digitimes is typically one of the more reputable sources https://t.co/yDUu8XFWtF

  12. 个股论点 $FORM

    看好 FORM,但更偏向台湾日本的小众玩家。

    @JonkooTrades 我今年 / 去年早些时候做多过 $FORM。 我个人觉得它大概率还会继续涨,但台湾 / 日本那边还有一些不那么出名的玩家,潜在上涨空间更大。

    英文原文

    @JonkooTrades I was long $FORM earlier this year/last year. IMO probably going to keep going up but there’s higher upside from some lesser known players over in Taiwan/Japan.

  13. 杂谈

    说自己只是泛泛提生态。

    @Roadstockz 哈哈……我只是泛泛地在说整个生态。 这些追踪我帖子的平台算法有点疯狂了。

    英文原文

    @Roadstockz lol… I’m just broadly mentioning the ecosystem. These algorithms tracking my my posts are going a little insane

  14. 供应链分析 $FORM$AEHR$TER

    列出硅光晶圆测试瓶颈相关的几个标的。

    硅光扩产碰到了晶圆测试瓶颈” - $FORM(ficontec 离开后更有帮助),$AEHR - 台湾这边有 MPI(6223)、MA-tek(3587)、MSScorps(6830) - 再往上还有大市值的 $TER、Advantest(6857) 如果你感兴趣,这些大概是我脑子里能立刻想到的一些不错曝光。 我很快会给大家做一个更深入的 ETF 版本。

    英文原文

    "Silicon photonics scaling hits wafer testing bottleneck" - $FORM (helps that ficontec left), $AEHR - Over in Taiwan MPI (6223), MA-tek (3587), MSScorps (6830) - Then large cap Cap - $TER, Advantest (6857) Are some decent exposure off the top of my head if you’re curious. I’ll make a deeper dive ETF for you all soon.

  15. 方法论

    说会做一个长期 CPO 受益者 ETF。

    @aiden1969 @afasano23 对,我很快会做一个长期 1 年期、只包含纯 CPO 受益者的 ETF,然后发出来。 只是研究真的很耗时间。

    英文原文

    @aiden1969 @afasano23 Yeah I’ll make a long term 1Y ETF on pure play CPO beneficiaries soon and post it It just takes a ton of time for research

  16. 方法论

    认为 2026 下半年是向更纯粹 CPO 名字轮动的好时点。

    在那个会远远持续到 2028 年以后的光子超级周期里?不是。 不过这个板块里,确实可能会在一些名字之间轮动,比如从 pluggables 轮到更多 CPO 名字…… 2026 上半年到下半年,可能是转向更多纯玩法名字的不错轮动时点,因为放量会在下半年后段到来。

    英文原文

    During the optical supercycle that lasts way past 2028+? No. There’s likely going to be rotations in certain names in the sector eg. Pluggables into more CPO names though… 2026 h1 into h2 is probably a decent rotation timing to more pure play names coming up since volume ramp latter part h2

  17. 供应链分析 $SOI$SIVE

    Soitec 反弹后继续看好 CPO/硅光主线。

    自从我发出 TLDR 版 thesis 后,Soitec 现在一个月涨了 64%。 很多人在我发帖后又因为伊朗 / 宏观回调,把 $SOI 说成“没有基本面的 meme 股”。 但我的多头,尤其是像 $SIVE 这类会延伸到 2029 年的 CPO / Silicon Photonics 相关标的…… 有时候就是需要时间兑现? 它在衬底层面是真正的垄断,而且它那些旧业务拖累板块也很可能正在见底。

    英文原文

    Soitec is now up 64% in 1 month since my TLDR thesis post. Lot of people made fun of $SOI as a “no fundamentals meme stock” when it corrected after I posted (because of Iran/macro). But my longs, especially with CPO/Silicon Photonics related stuff like $SIVE that scales into 2029. Sometimes just need time to play out? It’s a genuine monopoly in the substrate layer and it’s likely bottoming in their legacy drag segments.

  18. 供应链分析 $ALRIB$MSFT$IQE$QD Laser$LWLG

    越看越觉得 ALRIB 很有吸引力。

    $ALRIB 这只我开始越看越顺眼了。 首先,它有 $MSFT Quantum 作为核心 hyperscaler 客户。 然后它还有像 QD Laser 这样的量子点客户……以及像 $IQE 这样的光子晶圆代工客户。 而且它是盈利的,还在分红…… 在 MBE 领域也是真正的双寡头。 再加上新的硅光机器突破,订单簿还在加速增长…… 我一直把 $LWLG 和 Riber 这种东西拿来对比,然后就一直在想: 这在当前价格下,难道不就是很有吸引力吗?

    英文原文

    $ALRIB is starting to grow on me. First they have $MSFT Quantum as their core hyperscaler customer. Then they have Quantum Dot like QD Laser… and photonics foundries like $IQE as customers. And it’s profitable + paying dividends… And a genuine duopoly in the MBE space. And accelerating order book growth with a new breakthrough in silicon photonics machines.. I keep comparing $LWLG with stuff like Riber, then I keep thinking: Isn’t this just highly compelling at current prices?

  19. 杂谈

    说无意中也会带动别国经济。

    @MacnBTC 哈哈,思想探索的一个无意副作用就是会带动别国经济。

    英文原文

    @MacnBTC lol an unintended side effect of an thought exploration is boosting other country economies

  20. 杂谈

    说算法最近很烦,还会识别 1 美元订阅。

    @jukan05 对,最近这些算法真的越来越烦了。我还以为订阅制能打乱它们,结果它们居然连 1 美元都能付。

    英文原文

    @jukan05 Yeah algorithms have been getting really annoying recently. I thought subscriber-only would disrupt them but I guess they know how to pay $1.

  21. 供应链分析 $AXTI

    认为市场只是发现了一个 AI 基础设施脆弱点。

    @beauty_oe 没办法啊!这只是单纯的信息发现和整合,市场自己后来才意识到而已。 我发帖的时候它还按 0.5 倍市净率交易,所以就算涨了 80%,也只是回到 1 倍市净率而已…… 而且那还是整个 AI 基础设施构建链条里的一个重大脆弱点。

    英文原文

    @beauty_oe 仕方ないじゃん! 単なる情報の発見と統合で、市場がそれに気づいただけだよ。 私が投稿した時はPBR0.5倍で取引されてたから、たとえ80%上がったってやっとPBR1倍に戻るだけだし… しかもそれって、AIインフラ構築全体における重大な脆弱性でもあったりするんだよね。

  22. 供应链分析 $AXTI

    说自己最早把 AXTI 和 photonics 瓶颈联系起来。

    @Kelvinccccccccc 也许是因为没人知道吧? 我是最早把 $AXTI 和 photonics 瓶颈联系起来的人之一。 而 NCI 是更小众、位于上游的红磷供应商,而这些红磷又是制造 InP 衬底所必需的。 所以它其实是“瓶颈里的更瓶颈”的那种存在。

    英文原文

    @Kelvinccccccccc Maybe because nobody knew about it? I was one of the first people to point out $AXTI in relation to photonics bottlenecks. And NCI is an even more the niche upstream red phosphorus supplier needed to make InP substrates. So the even more unknown bottleneck of a bottleneck.

  23. 方法论

    说这是一个用小预算扰动 AI 建设的教育演练。

    @BrokeBoyCap 这只是一个教育性演练,看看如何用“柠檬水摊预算”去扰动整个 AI buildout。 不是看多建议,也不是什么投资推荐。

    英文原文

    @BrokeBoyCap This is just an educational exercise on how one might disrupt the entire AI buildout with a lemonade stand budget. Not a long recommendation or anything.

  24. 供应链分析

    补充 NCI 才是高纯红磷的主导供应商。

    rasa 虽然也是双寡头之一,但和 NCI 比,它在红磷这块更多算是次级供应商。 我更在意的是集中度比例,而 NCI 是全球领头羊。不过没错,你可以买两家,而西方世界基本上已经没法自己生产高纯度红磷了…… 也就没法再做 InP 衬底……也就没法再做 photonics

    英文原文

    rasa is a duopoly but they're considered a secondary supplier for red phosphorus compared to NCI. I cared more about concentration %, where NCI is the world's leader. But yes, you can buy both and the Western world basically can't make high purity red phosphorous anymore... and no more inp substrates... and no more photonics.

  25. 杂谈

    说自己只是为了世界统治图个乐。

    @TheCryptoRocky 我只是乐在其中地画一张世界统治的图。 可惜我不是 Elon,所以我还是有预算限制的……

    英文原文

    @TheCryptoRocky I'm just having fun plotting for world domination. Unfortunately I'm not Elon, so I do have a budget...

  26. 供应链分析 $AXTI

    说日本出口管制能反制中国的红磷供应。

    $AXTI 确实依赖像 NCI 这样的公司,所以中国的 AI 供应链实际上会被日本卡住。 所以我希望日本能在高纯红磷上用出口管制把中国反制回去,算是对 Jan 当年出口管制的回敬。 不过中国也在提升本土产能,但目前还不够。

    英文原文

    $AXTI does rely on companies like NCI, so China's AI supply chains would actually get bottlenecked by Japan. So I hope Japan export controls China back on high purity red phosphorus as payback for Jan's export controls. China is scaling up domestic capacity though but it's still not enough yet.

  27. 杂谈

    说自己想筹钱买下这家公司,但觉得太麻烦。

    @hypedplugarya 我本来在想要不要筹钱直接把这家公司买下来…… 但后来觉得太麻烦了,就干脆把这个漏洞发出来了。

    英文原文

    @hypedplugarya I was thinking about raising funds just to buy out this company... But thought it was too much of a hassle so just decided to post this vulnerability.

  28. 用 1.69 亿美元撬动西方 hyperscaler 供应链。

    Serenity 指南: 如何只用 1.7 亿美元就让西方 hyperscaler buildout 变得更脆弱。 只要用 1.69 亿美元拿下 Nippon Chemical(4092)! 做 InP 衬底需要:铟和高纯磷。 你以为 $AXTI 是瓶颈?NCI 才是瓶颈里的瓶颈。 NCI 实际上是高纯红磷卡点的领头羊,份额大约 26-27%(Rasa 更少,其余就是中国)。 而且它们向 $AXTI、Sumitomo、JX 供应这些材料,用来做 InP 衬底。 所以……如果你拿出 1.6 亿美元收购 NCI(再加上 Rasa 作为更小产能),你就能移除西方世界生产 6N/7N 红磷、也就是制造 InP 衬底所需的主力产能! 没有 InP 衬底:就没有 photonics。 有趣的是:中国科技公司其实也会被 NCI 打乱。 对 $AXTI 来说,这个映射 / 依赖关系其实非常有意思: - AXT 的 Tongmei 在 STAR Market 上市时就披露过,它在结构上依赖从日本进口高纯前驱体材料 - WITS 数据显示,大约 460 美元 / 公斤的高纯磷正从日本流向中国 所以它们确实在暗中依赖 NCI。 中国虽然也有 Wylton Chemical、Qin Xi New Materials、Jinding Electronics、Chuxiong Chuanzhi、Guizhou Wylton Jinglin Electronic Materials 这类产能。 但这些都还是更小的玩家,没法在规模化 InP 衬底生产上替代 NCI 提供的高纯红磷产能。 $LITE 的 CEO 之前就说过 InP 衬底让他夜不能寐。 所以现在有了 NCI,你就能让他永久失眠? 只要 1.69 亿美元。 所以供应链大概是这样: -> DGC 磷矿开采后运给 NCI -> NCI 把黄磷精炼成高纯红磷 -> Sumitomo / JX / AXT 把红磷和铟熔合,长成 InP 衬底 -> $COHR / $LITE 把 InP 衬底做成激光器 -> Innolight / Fabrinet 把它们封装成 800G / 1.6T 收发器 -> $NVDA / $GOOGL 用在 ASIC / GPU 集群里。 基本上,整个西方都依赖 NCI 来制造用于 photonics 的 InP 衬底。 我持有一点很小的仓位,纯属好玩。不过日本并不以随意提价著称。 所以如果你真的买下这家公司然后把价格抬高 15000%(比如政府意识到后把公司收回去),大概率会碰到监管问题,比如 FEFTA…… 也许提价 30-50% 还能压缩一下 forward P/E?但大概率不会最后变成 $AXTI 那样。 不管怎样,这家公司按大概 1.6 亿美元市值定价,本身就是一个巨大的国家安全风险。 至于基本面,它们市净率 0.54、forward P/E 11.4,所以其实也可能是被低估了。 TLDR: -> 它是下一个 $AXTI 吗?不是。 -> 它是不是西方 hyperscaler buildout + photonics 里一个未知的结构性瓶颈和关键漏洞?是。 -> 还有没有重估空间? 只要回到 1 倍市净率,立刻就有 80-85% 的上涨空间。如果再给它更高的 forward P/E,可能更多。 总之,用 1.69 亿美元找到 hyperscaler 供应链里的一个主要失效点,挺好玩的。

    英文原文

    A Guide by Serenity: How to Cripple the Western Hyperscaler buildout with just $170m. Just take over Nippon Chemical (4092) with $169m! For InP substrates, you need: Indium and High Purity Phosphorus. Thought $AXTI was a bottleneck? NCI is the bottleneck of the bottleneck. NCI is actually the leader of the high purity red phosphorus chokepoint holding 26-27% of the market share (Rasa has less share, then the rest is China). And they export to $AXTI, Sumitomo, JX that need it to make InP substrates. 
So… if you have $160m to spend to acquire NCI (plus Rasa as smaller capacity), you can remove the leading Western world’s production of 6N/7N red phosphorus needed to make InP substrates! And without InP substrates: no photonics. Fun fact: China’s tech companies would get pretty disrupted with it too by NCI. For $AXTI, the mapping/reliance is actually pretty interesting: - AXT's Tongmei outlined its structural reliance on importing high-purity precursor materials from Japan on their STAR Market listing 
- WITS data showing ~$460/kg high-purity phosphorus flowing from Japan into China So they secretly do depend on NCI. 
China does have capacity like Wylton Chemical, Qin Xi New Materials, Jinding Electronics, and Chuxiong Chuanzhi, Guizhou Wylton Jinglin Electronic Materials as well. However, they’re all smaller players so can’t make up for high purity red phosphorus capacity provided by NCI for InP substrate production at scale. $LITE CEO already said inp substrates keeps him up at night. So now with NCI, you can give the guy permanent insomnia? For just $169M. So here's what the supply chain looks like: -> DGC phosphate rock mine and ships it to NCI -> NCI refines Yellow Phosphorus into High Purity Red Phosphorus -> Sumitomo / JX / AXT melt the Red Phosphorus with Indium to grow InP Substrates -> $COHR / $LITE fab InP substrates into Lasers -> Innolight/Fabrinet package them into 800G/1.6T transceivers -> $NVDA / $GOOGL use them for ASIC/GPU clusters. 
And basically, the entire West depends on NCI to make InP substrates for photonics. I hold some very small positions, just for fun. However, Japan is not well known for price hiking. So you’d probably run into regulatory problems eg. FEFTA if you bought the company and hiked prices 15000% (like government seizing back the company once they realize)… Maybe 30-50% hikes is possible to compress fwd p/e? But very likely wont end up like $AXTI. 
 Regardless, this company is a massive, massive national security risk priced at ~$160m. As for fundamentals, they’re trading at .54 book value and a forward P/E of 11.4 so it’s probably undervalued anyway. TLDR: -> Is it the next $AXTI? No. -> Is it an unknown structural bottleneck + critical vulnerability of the Western hyperscaler buildout with photonics? Yes. -> Is there still room for re-rating? Just reverting to Book Value of 1 is immediate 80-85% upside. Maybe more if you give it multiples past 11 fwd p/e. Regardless, it’s fun to find a major point of failure in the hyperscaler supply chains for $169m.

  29. 杂谈 $NBIS

    说自己很喜欢 NBIS 的广告。

    @demian_ai 喜欢 $NBIS 的广告,今天路过还看到一个! https://t.co/cULR1DkIpN

  30. 杂谈

    说他们都被一个 Tangerine Peel 粉丝做空了。

    @thinklikekai 他们俩都被一个 Tangerine Peel 粉丝做空了。

    英文原文

    @thinklikekai They're both shorted by a Tangerine Peel fan.
