  1. 杂谈

    确认发布TA-35指数,其涨幅与TA-125相当。

    @OShtark 是的,我在帖子中发布了 TA-35 指数。它的涨幅与 TA-125 指数大致相同。https://t.co/kvomzvijpS

    英文原文

    @OShtark Yes I posted the TA-35 index in the post. It’s up around the same amount as TA-125. https://t.co/kvomzvijpS

  2. 杂谈

    以色列股市大涨,市场定价对伊“决定性胜利”预期。

    以色列证券交易所实时市场上涨 8.85%。 本地指数今日也上涨 4.23%。 当导弹飞向以色列时,这看起来荒谬至极。 然而,市场可能正在定价“决定性胜利”的感知以及伊朗长期风险的降低。 https://t.co/3TVhXvLs8T

    英文原文

    Israel’s stock exchange is up 8.85% in live markets now. The local index is up 4.23% today as well. It looks absurd as missiles fly toward Israel. However, markets are likely pricing in the perception of a "decisive victory" and long-term risk reduction of Iran. https://t.co/3TVhXvLs8T

  3. 杂谈 $TSE

    对比中东股市停摆,质疑以色列是否为例外。

    @thexanguy 我仍然认为这一观点成立。由于伊朗袭击了其基础设施,阿联酋/科威特曾全面暂停股市交易。此外还有 $TSE 的螺旋式下跌。也许以色列是罕见的例外?

    英文原文

    @thexanguy Still think it holds true. UAE/Kuwait had a total stock market halt since Iran hit their infrastructure. Then there’s the spiral of the $TSE. Maybe Israel is the rare exception?

  4. 供应链分析 $ETOR$NBIS$VLN

    伊朗战争或消除以色列及关联股的生存折价,需进一步研究。

    我也没料到这一点。也许伊朗战争的后果消除了相关股票如 $NBIS 以及以色列股票如 $ETOR 至 $VLN 的“生存折价因子”(existential discount factor)? 或者情况是多方面的,因为国防在以色列股市中占很大权重。 鉴于这对我来说是新领域,仍在做更多研究。

    英文原文

    I was not expecting this as well. Maybe the implications of the Iran war removes Israel’s existential discount factor on correlated stocks like $NBIS and Israeli ones like $ETOR to $VLN? Or its multifaceted since defense makes up a large weighting of the Israel stock exchange. Still doing more research since this is new to me.

  5. 方法论

    建议追踪内存及云厂商预测而非宏观,利用隔夜波动获利。

    我只想说,与其关注宏观数据,不如追踪内存价格涨幅和超大规模云服务商的预测可能更好。 宏观数据的影响主要是间接的,体现在能源成本(转嫁成本)以及流动性和波动性上。 话虽如此,隔夜数据往往会大幅夸大市场波动,因此可以利用这一点来获利。

    英文原文

    I would only say it might be better to track memory hikes and hyperscaler projections over macro. Consequences are mainly indirect in terms of energy costs (pass through cost) and just liquidity/volatility. That being said overnight does exaggerate movements a lot so could always take advantage of that

  6. 个股论点 $SNDK

    NAND价格暴涨,SanDisk要求预付锁定供应。

    对于 $SNDK 来说,这可能只是宏观因素,尤其是如果要求预付未来三年的款项的话 lol “自2025年下半年以来,NAND 合约价格已多轮翻倍,据报道过去六个月累计涨幅高达500%。此前,美国 NAND 制造商 SanDisk 要求下游客户全额预付以锁定未来一到三年的供应。”

    英文原文

    Might just be macro for $SNDK especially if there’s prepayment for three years ahead lol “Since the second half of 2025, NAND contract prices have doubled in multiple rounds, with cumulative increases reportedly reaching as high as 500% over the past six months. Earlier, U.S.-based NAND manufacturer SanDisk required downstream customers to prepay in full to secure supply for the next one to three years”

  7. 个股论点 $AAOI

    AAOI营收预测惊人,高增长低估值,成光子学核心持仓。

    $AAOI 并不关心伊朗的战争局势。 这只光子学股票拥有令人惊讶的约 900% 营收增长爆发式预测: 到 2027 年中,年化经常性收入 (ARR) 将达到 45.3 亿美元,毛利率约为 40%。 再加上两位数方向性的串行接口 (SI) 供应短缺。 可能并不需要(担心这些宏观或供应链问题)。

    英文原文

    $AAOI does not concern itself with a war in Iran. The photonics stock with surprise ~900% revenue growth blowout projections to: $4.53B ARR by mid-2027, off ~40% margins. Coupled with double digit directional SI stuck. Might not need to be. https://t.co/qKReNvBMYh

  8. 供应链分析

    三星与海力士大幅上调DRAM价格,NAND涨500%,内存需求强劲。

    据 Digitimes 今日报道,三星电子(Samsung Electronics)和 SK 海力士(SK Hynix)大幅上调 DRAM 价格。 部分消息源自本周《首尔经济日报》的报道,其中指出: “客户可能需要接受比之前合同价格高出一倍以上的价格,才能获得 DRAM 配额”。 DRAM 价格的急剧上涨伴随着 NAND 价格的上涨,今日“群联(Phison)因 NAND 价格上涨 500% 而转向预付款模式”。 内存需求存在一个无情的黑洞。

    英文原文

    Samsung Electronics and SK Hynix reportedly sharp DRAM price increases from Digitimes today. Part of source was the Seoul Economic Daily report this week that stated: “Customers may need to accept prices more than double their previous contract rates to receive DRAM allocations”. The sharp DRAM price hikes come with NAND price hikes as “Phison shifts to prepayments as NAND prices hike 500%” today. There is a relentless black hole on memory demand.

  9. 供应链分析

    Soitec对CPO至关重要,虽早但不可或缺

    @beauty_oe 我觉得索伊特克(Soitec)现在投资还稍微有点早。所以我原本打算明年再投资。不过,对于预计在2028年左右普及的共封装光学(CPO)来说,它似乎将成为一个巨大的瓶颈(不可或缺的存在)!

    英文原文

    @beauty_oe ソイテック(Soitec)はまだ少し早すぎる気がします。なので、投資は来年にしようと思っていました。でも、2028年頃に普及するCPO(共同パッケージ光技術)にとっては、大きなボトルネック(不可欠な存在)になりそうですね!

  10. 方法论

    认为当前入场太早,暂不持仓,仅监控其他代工厂信号。

    我目前没有持仓,因为我认为现在仍然太早。我不想仅仅因为两年后才会发生的事情就持有一个头寸。这与提前布局2028年比特币减半类似,现在开始有点太早了。也许提前6-8个月,比如2027年第二季度初。话虽如此,监控其他晶圆代工厂可能是一个很好的信号,但我个人还没有专门跟踪Soitec。

    英文原文

    Don’t have positions since I thought it’s still way too early. Don’t want to jut sit on something that’s happening 2Y later. Same with front running 2028 Bitcoin halving, starting now is a tad early. Maybe like 6M-8M in advance, like early q2 2027. That being said monitoring the other foundries are probably a good signal but I personally haven’t been tracking it yet for soitec in specific

  11. 个股论点

    CPO瓶颈股估值低但受拖累,建议暂持或寻找其他机会。

    智能手机及其他业务带来的传统拖累。 随后是巨大的资本支出周期,目前正为2027-2028年晚期的产能爬坡做准备。 所以可能更好的策略是将其作为记账头寸持有,明年年初再回来处理。除非市场开始提前抢跑。 14亿欧元的市值对于共封装光学(CPO)的功能性垄断瓶颈来说真的很便宜。但作为一名交易者,未来一年可能在其他地方有更好的机会。

    英文原文

    Legacy drag from smartphones and other businesses. Then massive capex cycle now to prepare for late 2027-2028 ramp. So might just be better off bookmaking it and coming back early next year. Unless markets start frontrunning it early. 1.4B euro MC is really cheap for functional monopoly bottleneck for cpo. But as a trader, probably better opportunities elsewhere for the next year

  12. 供应链分析 $AXTI$IQE$SLOIF

    Soitec是CPO关键瓶颈,预计2028年随CPO拐点迎来估值重估。

    Soitec ($SLOIF) 是 $AXTI 在硅光子学领域的垄断性镜像标的。 基本上,它与共封装光学(CPO) 直接绑定,其拐点预计在 2027 年底至 2028 年。 对于 800G/1.6T 和 CPO 而言,没有 $AXTI 和 Soitec 很难实现: AXT 提供磷化铟(InP) Soitec 提供光子学绝缘体上硅(Photonics-SOI) 衬底。具有功能性垄断地位。 (Shin Etsu 在其授权下运营)->(英特尔、格芯、Tower) 但预计当 CPO 在 2028 年初触及拐点时,它们的估值将大幅重估。 然而,与 $IQE 类似,大量传统业务拖累影响着其股价。 对于 $AXTI,供应挤压正在发生。 对于 Soitec,可能早了 6 个月或一年,但不知道市场何时开始抢跑。 但这只是将其作为一个未来的瓶颈环节提出。

    英文原文

    Soitec ( $SLOIF ) is the monopoly silicon photonics mirror to $AXTI. Basically it’s directly tethered to CPO and its inflection point late 2027-2028 For 800g/1.6T and CPO, hard to really do it without $AXTI and Soitec: AXT for InP Soitec for photonics-soi substrates. Functional monopoly (Shin Etsy operates under their license) -> (Intel, Global Foundaties, Tower) But expect them to get rerated extremely hard early 2028 when CPO hits the inflection point. However similar to $IQE, there’s tons of legacy drag affecting their stock price. For $AXTI the supply squeeze is happening now. For Soitec might be 6 months or a year too early but don’t know when markets start frontrunning it. But just putting it out there as a future bottleneck.

  13. 供应链分析

    从半导体瓶颈向运行瓶颈的板块轮动逻辑合理。

    @zephyr_z9 从半导体瓶颈(SeMI bottlenecks)板块轮动至运行瓶颈(Running bottlenecks)板块是合理的。

    英文原文

    @zephyr_z9 Rotation from semi bottlenecks into running bottlenecks makes sense

  14. 个股论点 $SNDK

    Macronix 是 NOR Flash 最纯标的,需更陡峭涨幅才能重现 SNDK 走势。

    我之前讨论过的 Macronix,主要涉及 NOR Flash(Nor 闪存)。由于它占据 30-35% 的市场份额,且市值(MC)仅为 67 亿美元,远低于其他竞争对手的 150 亿美元以上,因此它是该板块中最纯粹的标的。目前的涨幅相当温和,若要重现 $SNDK 的走势,其涨幅需要陡峭得多。

    英文原文

    Macronix I've talked about earlier on for NOR Flash. It's probably the most pure play out of the bunch since it's 30-35% of the market with a smaller MC of $6.7B compared to the others at $15B+ The hikes have been pretty modest so far, for it to pull a $SNDK, it will need to be a lot steeper.

  15. 杂谈

    博主澄清无付费网站,警示外部链接骗局。

    @Pearsonpc @Serenity 我没有任何付费网站或外部页面。那些很可能是骗局。

    英文原文

    @Pearsonpc @Serenity I don't have any paid sites or external page. Those are are likely scams.

  16. 杂谈 $IBKR

    建议开通盈透证券账户以交易国际市场

    @ramprasadenaik 开通盈透证券($IBKR)账户以获取国际市场交易权限

    英文原文

    @ramprasadenaik Get an $IBKR account for access to international markets

  17. 供应链分析 $NVDA

    NOR Flash涨价潮确认,GB200单机架成本激增,推荐宏碁与华邦。

    NOR Flash 会是继 HBM/DRAM 之后的下一个内存供应瓶颈吗? 近期,MCU(微控制器)、NOR Flash、KGD(裸晶)封装存储以及功率器件的价格上涨了 10% 至 80%。 涉及涨价的公司名单包括: - 华润微 - 中芯国际 - 北京君正 - 戈麦斯微电子 - 盈佳芯 - 兆易创新 - 欧姆龙 - ADI - 英飞凌 所有这些公司都提高了价格。更具体地说,中国的兆易创新将 MCU 和 NOR Flash 的价格提高了 15%–50%,普冉半导体也提高了 NOR Flash 的价格。 这证实了此前关于 $NVDA GB200 NVL72 系统的预测,即每个机架的 NOR 内容成本已超过 600 美元,并可能开始上调至 900 美元(增加 50%)。 投资者通常喜欢听到涨价的声音,因此对于相关敞口: - 宏碁半导体 (YTD: +153%) - 华邦电子 (YTD: +34.91%) 是该板块的两个最佳标的。 因为它们各自拥有 33-35% 的市场份额,尽管 TAM(总可寻址市场)较小。英飞凌等其他公司对于纯主题投资来说只是杯水车薪。

    英文原文

    Is NOR Flash the next memory supply squeeze from HBM/DRAM? Recently 10% to 80% hikes were made to: MCUs, NOR Flash, KGD package storage, and power devices recently. The list of companies spanning: - China Resources Microelectronics - SMIC Semiconductor - Belling - Goke Microelectronics - Yingjixin - Maxscend - Omron - ADI - Infineon have all increased prices. More specifically, China's Cmsemicon raised MCU and NOR Flash prices by 15%–50% and Puya Semiconductor raised NOR Flash prices. This helped confirm earlier projections regarding $NVDA GB200 NVL72 systems that NOR content per rack already exceeds $600 and could start hiking rates to $900 (+50% increase). Investors usually like to hear the sound of price hikes so for exposure: - Macronix (YTD: +153%) - Winbond (YTD: +34.91%) are the two best exposures for the segment. Since they both hold 33-35% of market share each, though a smaller TAM. Infineon and others look to a drop in the bucket for pure play exposure.

  18. 个股论点 $XLU

    建议等待 $XLU 回调且 IV 降至 14-16% 时入场。

    @btc_overflow 我会等待回调(如果有的话)再买入 $XLU,并在行权价的隐含波动率(IV)降至 14-16% 左右时入场。 如果它继续上涨,你也不会损失什么,只是错过了众多机会中的一个。

    英文原文

    @btc_overflow I’d wait for a correction (if there is one) for $XLU and for IV on a strike to be around 14-16% to enter. If it keeps going up you don’t lose anything, just miss out on an opportunity among others.

  19. 个股论点 $NBIS$UBER

    看好NBIS多业务高增长及分部价值,预期其现金流转正后估值重估。

    $NBIS 是我在这批新云厂商中真正最看好的。情况很微妙,但他们本质上是由 5 家不同业务组成的公司,且均实现三位数的同比增长。我最看好其与 $UBER 合作的自动驾驶出租车部门,以及 Clickhouse(他们持有约 1/4 股份),这两块未来估值很可能远超 150 亿美元。此外,其数据中心业务预计将在 2027 年 2 月报告前上线,带来约 70-90 亿美元的年度经常性收入 (ARR)。我认为市场尚未充分反映其分部加总价值,但我预计在其低调建设阶段结束、资本支出 (Capex) 开始转化为自由现金流 (FCF) 后,Nebius 的估值将得到重估。

    英文原文

    $NBIS is my actually favorite Neocloud out of the bunch. It’s really nuanced but they actually are basically 5 different companies all scaling triple digits y/y. Biggest fan of their robotaxi division working with $UBER and Clickhouse would likely command higher valuations in the future than $15B (they own ~1/4th). This is on top of their DC business expected to come online and bring ~$7-9B ARR by Feb 2027 report. Don’t think sum of parts is priced in properly but I’d expect Nebius to be rerated after their silent buildout phase ends and they start turning capex to fcf

  20. 个股论点 $IREN$NBIS

    不看好IREN因稀释风险,更信任NBIS管理层,静待时间验证。

    我不看好做多 $IREN,除非他们停止 GPU 业务并转向纯数据中心托管(Colo)业务。现在的投资者将面临为了变现其 3GW 产能而进行的无休止稀释。话虽如此,它确实具有更高的潜在回报,但我个人更信任 $NBIS 的管理层。过去我在 $NBIS 与 $IREN 之间有过很多辩论,时间会证明谁是对的。

    英文原文

    Not a fan of $IREN as a long unless they stop doing GPU offerings and pivot to do pure colo. investors now will be met with endless dilution to monetize their 3GW capacity. That being said it does carry higher potential returns but I personally trust in $NBIS management more. I’ve had a lot of debates in the past between $NBIS vs $IREN but time will tell whose right

  21. 个股论点 $CRCL$CRWV$NBIS$NVDA

    CRWV大跌验证看空逻辑,警示新云债务风险差异。

    这条推文经得起时间考验,$CRWV 过去一个月下跌约 28%。 我觉得最好的空头其实是多头投资者或波段交易者。 如果你看到 Coreweave 或 $CRCL 在 200 美元时的危险信号,与其回避,不如反向操作。 话虽如此,$NBIS 等其他股票正随着板块被算法性打压。 我一次又一次地注意到,并非所有新云服务商(Neoclouds)都是一样的。 - 一家新云服务商可能有数十亿美元的年度债务利息,损害自由现金流(FCF) - 另一家则可能没有……

    英文原文

    This aged well, $CRWV down ~28% in the past month. I feel like the best bears would actually be long investors or swing traders. If you see red flags, with Coreweave or $CRCL at $200, can always play the other direction instead of avoiding it. That being said, $NBIS and others have been being brought down algorithmically with the sector I’ve noticed this again and again, not all Neoclouds are built the same. - One Neocloud might have billions in yearly debt interest hurting FCF - The other Neocloud might not…

  22. 个股论点

    建议等待更好入场点,长期看好AI推理与降息驱动的上涨。

    @Edu4rdo26 如果你打算买入,建议等待更好的入场时机。1个月10.42%的回报率已经超过了其长期正常回报水平。但从长期来看,我预计其方向将向上,并有望迎来由AI推理(AI Inference)需求爆发和降息驱动的“一生一次”级别的行情。

    英文原文

    @Edu4rdo26 If you do, probably wait for a better entry. 10.42% 1M return is already more than what it would normally return across a long time. But long term I expect it to be directionally up with a once-a-lifetime type run from AI inference usage and rate cuts

  23. 方法论

    期权交易受价差、入场点及IV影响,且远期合约定价异常。

    是的,这很大程度上取决于初始成交情况,因为买卖价差很宽,以及入场点(例如,如果你是在日内+1%或-1%的回调时买入),还有隐含波动率(IV)(做市商(MMs)众所周知会在开盘时抬高某些行权价的价格)。 奇怪的是,我发现2028年1月的期权链相比2027年12月的似乎略微被高估了。

    英文原文

    Yeah largely depends on initial fill since spreads are wide, entry points (eg. If you bought at an intraday +1% or -1% dip), and IV (MMs are known to elevate some strikes market open) I found the Jan 2028 option chain to be slightly overpriced compared to Dec 2027 one strangely enough

  24. 个股论点 $XLU

    分析$XLU期权因低波动率特性,小幅波动即可带来高收益。

    回复 @walteryhooper:$XLU 的 IV(隐含波动率)自2000年以来仅移动了82%(未计入股息),因此只要价格波动3%并伴随轻微的 Vega(波动率风险)扩张,收益就能轻松翻倍。 https://t.co/eCIEyAVd0F

    英文原文

    @walteryhooper IV for $XLU was 14% since the ETF has only moved 82% since year 2000 (not account for dividends). So a 3% movement with slight vega expansion is easily a double. https://t.co/eCIEyAVd0F

  25. 业绩复盘 $XLU

    博主分享期权大涨144%及XLU周涨幅示例

    @Ngen704 我那些极度虚值(OTM)的看涨期权已经上涨了144%+。我刚才只是以接近平值(ITM)的行权价为例,来说明 $XLU 本周3%的涨幅 https://t.co/PhgmsJDz39

    英文原文

    @Ngen704 My very OTM calls are up 144%+ I was just sharing closer to ITM strike as an example of the 3% increase this week for $XLU https://t.co/PhgmsJDz39

  26. 个股论点 $GRID

    聚焦$GRID在美国电网现代化及降息中的机会,并澄清时间范围。

    @cafeaulaitfr $GRID 是全球性的,我专注于美国电力/电网现代化与降息。此外,日期仅涵盖至今年9月,而非2028年。

    英文原文

    @cafeaulaitfr $GRID is global, I’m focusing on US power/grid modernization coupled with rate cuts. Also the dates only go out to September this year instead of 2028

  27. 个股论点 $XLU

    看好$XLU,认为电网升级是AI时代美国工业产能的关键。

    埃隆在敲响警钟,指出电力/电网对美国在AI领域的统治地位至关重要时,完全正确。 我此前对$XLU(电网/电力公用事业ETF)发出的“千载难逢”行情预测正在实时兑现。 新的看涨期权(Calls)仅在一周内就已上涨约100%+。 电力发电和电网是工业产能的衡量标准,美国有充分的动力对其进行现代化改造和扩张。

    英文原文

    Elon is completely right when he sounds the alarm that power/grid is vital for US dominance in AI. My call for the once in a lifetime run for $XLU (grid/power utilities ETF) is playing out real time. New calls are already up ~100%+ in the week alone. Power generation and the grid is a measurement of industrial capacity and the US has every motivation to modernize and expand it.

  28. 杂谈

    作者认为特朗普政府的举措在地缘政治上取得了最佳成果,尽管遭道德批评。

    谢谢。这两个月可能会成为特朗普政府历史上最传奇但最不被欣赏的时刻之一。许多媒体和左翼政客从道德角度对此进行批评。但从经济/地缘政治主导权来看:这可能是美国在不与俄罗斯和中国发生直接冲突的情况下所能希望的最佳结果。与这两个国家的外交讨论和条约不会改变任何现状。绝大多数人完全误解了实际的意图和影响。

    英文原文

    Thanks. This first two months will probably be one of the most legendary but unappreciated moments of Trump’s administration. Lot of media/left wing politicians are critizing this from a moral perspective. But economically/geopolitical dominance speaking: This was the probably the single best outcome America could ever hope for without getting into any direct conflict with Russia and China. Diplomatic discussions and treaties with either countries would not have changed anything. The vast majority of people completely misinterpreted the actual intentions and implications.
