@excu4e16421 @CodeToRun @cherryPayment 账面会亏点钱,但是无所谓得,拉到高位把fomo的买盘吃了,再砸
主要风险不是砸不动,而是砸下去会不会再fomo;砸下去没有流动性买怎么办。因此,比较好的策略是每天砸,让他连续跌,跌到多头绝望出来

我虽然在很多群里面,但不推荐任何群。因为群的noise太大
比较推荐的是几个订阅
@spotgamma (tool + volatility)
@ConvexValue (tool + volatility)
@alma18499 (volatility)
@KobeissiLetter (BB & Elliot Wave)
@TicTocTick (volume profile)
这些是技术加上对宏观/市场有自己深刻的理解
Michael Chen@QCCCCCCCCCCCC
@hhuang 好奇有什么群可以加

I wasn’t planning to share this, but it’s such a high-quality explanation of CPO that I have to.
Just watch it. You’ll regret it if you don’t.

只要大模型营收在强劲增长,巨头和中小企业采用AI在带来实际的持续增效,Capex就会继续增长,GPU等半导体及配套就会持续基建红利,相关公司就会继续涨。核心是前面的应用是否在赚钱,是否在降本增效,保持检验这点就够了。
时代的最大炮声在何处,一目了然。先全力以赴地吃透AI基建红利,就像第一次工业革命时的铁路,第二次工业革命时的电力,第三次工业革命时的通信。
我自己也是后知后觉,直到去年才开始深入半导体产业供应链,23年24年天天盯着币和撸毛,白费生命。@ShanghaoJin Herman老师是在24年四五月就开始喊半导体的,我一路亲眼见证,那个时候除了英伟达,整个半导体产业链还没起飞。
很多踏空半导体的人都在质疑AI,默认泡沫,张口闭口都是分析泡沫如何破灭,他们对半导体产业供应链内部的失衡结构完全无知。我觉得要多深入产业一线,要多听、多查、多信黄仁勋的讲话。
很多以前投资做得很成功的人,这次也不一定跟上来了,我身边就有不少例子,行业里圈子里也有很多很多这样的大v,他们根本就不懂半导体,也没有去深入。这样的人他会自然默认半导体是泡沫,然后继续守着以前的盘子,比如币,比如中概茅台腾讯,比如撸毛,等等。所以AI浪潮带来的这次基建红利,也是一次弯道超车的机会,它会造成一次很大的财富分化和重新洗牌。
我们要全力以赴,抓住这波AI基建红利大潮,对于光互联(CPO)、AI RAN、端侧AI(Edge AI)坚决信,长信,重仓猛干,完成翻身上岸。

The best performing thematic basket in our universe since the recent market lows is our “AI Power Plumbing” basket - comprised of analog semis names making capacitors, PSUs, inductors, magnetics, MLCCs and discrete power semis.
We were a bit early to this - at the end of 2024 , we flagged the whole analog stack between the grid and the GPU as boring, deeply cyclical, and an asymmetric corner of the AI buildout the market kept ignoring because of a dual China/Auto-cycle overhang. It took a little longer than we anticipated, but the analog cycle finally turned and content per server keeps climbing.
Names like TXN, MCHP, STM, ON, AOSL, VSH, DIOD, ADI, Infineon, MPWR, VICR, Murata Manufacturing, TDK, ALGM, WOLF, Nippon Chemicon, Sumida etc…a lot of quality names that still have a long way to go to match the re-rating of names in memory, optics and compute.

One quarter ago: AMD said CPU TAM could reach $60B by 2030, or 18% CAGR.
One month ago: AMD/Arm double the number to $120B by 2030, or roughly 35% CAGR.
This week: Nvidia is doubling again at $200B CPU TAM by 2030, or roughly 50% CAGR.
So makes people curious: how long before Intel, Nvidia, AMD, or Arm double the TAM number again?
If CPU TAM doubles once more to $400B by 2030E, that implies roughly 72% CAGR.
significantly higher than DRAM ~40% CAGR, NAND ~30% CAGR
given the CPU TAM CAGR update to 50%, plus DRAM per server CPU core is rising from 4GB to ~16GB or even 32GB in the future, DRAM CAGR is definitely going to be re-evaluated.

内地还能开户的美国券商:嘉信理财开户指南
如果你正在寻找一个稳定、合规且门槛极低的海外资产配置渠道,嘉信理财(Charles Schwab)几乎是必选项。

很多朋友担心资金安全,其实嘉信理财的背景非常硬核。上市公司, 美股代码 $SCHW$,财报全透明,接受市场全方位监督。它是美国金融监管局(FINRA)和证交会(SEC)的资深成员。并且加入了 SIPC(证券投资者保护公司),为每个账户提供最高 50 万美元 的保护。即便券商倒闭,你的钱也有兜底。
下面讲下开户流程:
访问网址:international.schwab.com/open-account-i…
特别提醒: 进入页面后,千万不要切换成中文! 切换中文会自动跳转到嘉信香港,那边要求本人去香港面签,非常麻烦。
只要看到左上角写着 「Charles Schwab International」,并且页面是全英文的,那就是对的。往下滑点击 「Individual Account」进入 开启你的美股之路。另外页面跳转有延时,耐心等待,不要点回退。
第一步:填写个人基本信息
选填的都可以跳过不填
FirstName: 名,拼音大写
LastName:姓,拼音大写
Citizenship:China
Date of birth:出生日期
联系方式:邮箱和电话,Country code:86(邮箱后面要接验证码)
护照信息:护照号、过期时间以及颁发国家China
输入邮箱验证码
居住地址,地址如实填写。使用谷歌翻译下中文地址,转为英文。Country和City不要出现在Street Address信息里。
有三行Street Address,把从区开始的地址填入第一行Street Address即可。这里的地址一定要和地址证明上的保持一致!
可以选择添加信任的联系人,也可以跳过
账户用途:选第一个,general purposes,一般投资
资金来源:选第一个,salary,wages or savings
是否被雇用:如实填写,如果在职,填写公司行业、公司名和地址
第二步:一些调研和账户设置
背景调查:全部选No
希望使用无纸化文件吗:全部勾选
融资Margin、期权交易Options trading、Thinkorswim交易平台,全部选yes
Thinkorswim平台拥有更强大的图表分析、期权交易工具、实时见解以及丰富的自定义功能,一定要开通。融资和期权交易建议也先选上。
选择期权策略级别:
级别 0:备兑 (Covered)
级别 1:做多 (Long)
级别 2:价差 (Spreads)
级别 3:裸期权 (Short Uncovered)
新手/稳健型:通常选择 Level 0 或 Level 1。
进阶型:如果你想玩牛市价差或熊市价差,需要选 Level 2(这通常需要你同时开通融资账户)。
级别越高,对你的交易经验和财务状况(如净资产、年收入)审核越严格。
接下来就是对你的收入和投资经验进行调查审核。
信息确认,没问题继续continue
勾选同意各种开户协议
上传护照文件和住址证明文件,文件名一定要是英文。可能会出现上传失败的情况,按照提示进行重试。
第三步:W-8BEN表格填写
这是开户必须要完成的,省钱的关键。
账户持有人信息,选择个人,这里的信息之前都已经填过了,进行确认即可,如果信息有误进行更正。
美国公民身份调查,全部选择否,选中国
既然嘉信不走 CRS,那填 W-8BEN 是不是暴露了?其实完全相反!W-8BEN 是美国政府发给咱们投资者的「税务通行证」。不填它,你赚的钱会被美国政府先扣掉一大块;填了它,你才能合法合规地享受美股对外国人的免税政策。 至于 CRS,那是另一个维度的信息交换,目前嘉信作为美国本土券商,确实还没加入那个「朋友圈」。
这些步骤完成后,则进入审核阶段,通过会发邮件通知。
审核阶段账户是可以正常登录的,但是不能进行交易。
嘉信理财官方网站有很多投资相关的学习内容以及平台操作指南,值得看看。学习入口:

$SMTC has a full-fledged product line that covers both copper and optics communications.
I traded and tweeted about $SMTC two years ago but never looked back. The more you look into it, the more surprised you'll be at how solid its fundamentals are in this competitive space.
Will spent more time on it.
Irrational Analysis@insane_analyst
If MTK TPU succeeds, SMTC is a 2-4x from here. If MTK TPU fails, SMTC is a 1.5-2x from here. SMTC CTLE can give 4-7 dB SNR gain. ~300G SerDes at PAM6 has 4-5 dB SNR penalty from theory. MTK would need 2-4 dB improvement in design + CPC + SMTC CTLE + good EMIB pkg to make it.

MLCCs are becoming a mainstream investment theme
The problem is that the main plays are already expensive:
- > Taiyo Yuden: 34x earnings
- > Murata: 42x earnings
The biggest opportunity is now in materials
━━━━━━━━━━━━━━━━━━
This is how the MLCC cycle will likely play out
➡️ MLCC makers, Murata, TDK, SEMCO, Yageo and Taiyo Yuden, raise prices for AI customers. These prices have already exploded.
➡️ 0 to 3 months: MLCC maker earnings benefit immediately from the price increase.
➡️ 6 to 12 months: MLCC makers renegotiate input costs with materials suppliers. These suppliers are still cheap.
➡️ 9 to 15 months: Materials suppliers’ earnings start reflecting the pass-through.
We are currently at month 0 to 3 for the April 2026 price hikes
Murata’s earnings already reflect Murata’s pricing power
NCI (4092.T) and Sakai (4078.T) have not yet reflected their portion of the pass-through, and both still trade at a forward P/E in the teens
━━━━━━━━━━━━━━━━━━
Materials suppliers historically capture 60% to 70% of MLCC ASP increases through supply contract renegotiations
The 15% to 35% Murata high-end MLCC price hike implies a 10% to 25% ASP uplift coming for NCI and Sakai’s high-end powders over the next 9 to 15 months
That is earnings growth that is essentially already in process, but the market has not priced it yet because materials suppliers report later in the cycle
