Interesting photonics selloff today on no news?

$LITE down -4.95%
$AAOI down -4.85%
$SIVE down -14.8%
$SOI down -5.73%
$AXTI down -8.13%
$IQE down -12.13%

I think it’s probably the most compelling theme going forward (even more than power semis).

Just tends to be very https://t.co/bWjGIak6OE

Back when $AAOI was ~$20-30 when I went long:

I thought $AMZN and $MSFT were qualifying specific optical transceivers for their ASIC programs.

Turns out it’s more interchangeable/mass producible.

Regardless, glad my thesis on $LITE, $AAOI, Innolight, $COHR, $AXTI played out so https://t.co/sYkMfQfHa2

Bro media… how is $XFAB a meme stock?

Can you not repeat the same mistake with $RPI this time?

They’re literally getting CHIPS ACT funding from the EU because of how critical they are.

And have $NVDA / $NOK evaluating their SiPH side of things, while they traded at a low https://t.co/vj9FyoDeHO

Look who joined team $NBIS.

5.6% is a pretty massive stake, maybe he realized by now it’s miles better than the dumpster fire that is $IREN.

That being said: Nebius is now up ~3x since I went long last year.

Weebius has plot armor. https://t.co/JYZvf3GJND

在 X 上看到这么多中文社区的支持,真的让人很开心!

这体现了种非常有趣的文化差异:

大家会试图了解我的思考过程和选股逻辑,并以此来完善自己的投资体系。

相比之下,其他些文化背景的人可能上来就会全盘否定。

也许我会为了好玩,开始写写对两支中国股票的看法,哪怕我并没有持仓。

$MRVL earnings were a bullish indicator on the broader CPO theme (and $SIVE as the likely laser supplier).

- “Scale-up interconnect represents one of the newest and most strategically important opportunities emerging in AI infrastructure.”

CPO thematically go brrr

Appreciate the more neutral coverage by Reuters and Bloomberg on $XFAB today.

Although it would be nicer to focus more on the structural thesis presented…

Around 800 vdc power semis $NVDA exposure + with ongoing $NVDA / $NOK evaluations for photonics.

And around CHIPS Act https://t.co/EXH09mhj76

Ayar’s announcement today with Wiwynn is potentially very material for $SIVE regarding CPO -> rack scale deployments.

As Wiwynn cloud clients include $AMZN, $META, $MSFT.

And they’ve been in talks for $GOOGL TPU deployments.

I think just for some reference architectures it’s https://t.co/6QqxffkZTs

超赞的文章!

看看大家怎么看待我的过往经历真的挺好玩的

最近我一直在努力多跟对供应链和AI感兴趣的小伙伴们互动

所以只要是想了解我思考逻辑的朋友,我都会尽量去关注

Oh look, $SOI is now up 4X+ since I went long.

And another 15%+ after earnings.

Despite media“analysts”claiming there was nothing new with Soitec.

The fact they’re trying to reorganize the company to answer demand for SOI substrates for photonics.

It’s a pretty positive https://t.co/hN6ySb2qoS

I genuinely think $XFAB is very compelling at $1.5B MC, despite recent volatility.

Per NIST filings stated they were the only high volume SiC foundry in America.

Making them extremely “critical infrastructure”… Verbatim from the US Gov.

And they’re the first comprehensive https://t.co/4OGXctOv5h

Just in case people are wondering about my track record with European equities:

$RPI: $280 -> $800 (agentic AI hardware demand thesis).

$LPK: ~$6, thesis at $13 -> $24.2 (glass cores substrates close monopoly)

$SOI: $44 -> $181 (silicon photonics, monopoly over substrates) https://t.co/EWWaVL7Y49

AI 总结

核心总结

  • 研究重点:光子学(photonics)及共封装光学(CPO)主题,包括硅光子、光电收发器、SOI衬底、SiC代工等,同时关注AI基础设施相关标的(如AI ASIC、agentic AI硬件、电力半导体)。
  • 交易观点:强烈看多光子学产业链,认为该主题比电力半导体更具前景;多次提及自己已长期持有多个标的并获得大幅收益;对$XFAB、$SIVE、$SOI等当前估值仍持积极态度。

涉及标的与方向

  • $SIVE:看多。CPO主题的激光供应商,$MRVL财报验证CPO趋势;Ayar与Wiwynn合作可能推动机架级部署,Wiwynn的客户包括$AMZN、$META、$MSFT,且正与$GOOGL洽谈TPU部署。(催化剂:$MRVL财报、Ayar/Wiwynn公告)
  • $SOI:看多。自做多以来涨4倍+,财报后涨15%+;公司重组以应对光子学对SOI衬底需求,媒体忽略其结构性变化。(催化剂:财报、重组进展)
  • $XFAB:看多(市值15亿美元有吸引力)。唯一美国高产量SiC代工厂,被美国政府认定为“关键基础设施”;获得欧盟CHIPS Act资助;$NVDA/$NOK正在评估其硅光子(SiPH)业务,同时有800V直流电力半导体及$NVDA敞口。(催化剂:CHIPS Act资金、NVDA/NOK评估、NIST文件确认关键地位)
  • $LITE$AAOI$AXTI$COHRInnolight:看多(历史上已获利)。光子学板块整体看多,昨日回调视为无理由卖压,属正常波动。
  • $NBIS:看多(自做多以来涨3倍)。有投资者买入5.6%大额股份;博主认为$NBIS远优于$IREN。
  • $MRVL:财报对CPO主题呈看涨信号,其管理层称“Scale-up interconnect是AI基础设施最新最重要的机会”。(间接利好$SIVE等)
  • $RPI:此前从280涨至800(agentic AI硬件需求);$LPK:从~6涨至24.2(玻璃基板接近垄断)——历史战绩参考,当前未提及最新观点。

催化剂与时间线

  • 已发生:$MRVL昨日财报确认CPO战略重要性;Ayar Labs与Wiwynn宣布合作(可能影响$SIVE);$SOI财报后大涨。
  • 进行中/预期:$NVDA和$NOK对$XFAB硅光子的评估结果;$XFAB的CHIPS Act资金落地;$SIVE在CPO/机架级部署中的订单进展;Wiwynn与$GOOGL的TPU部署谈判。

风险与不确定性

  • 板块波动:光子学板块昨日无理由下跌($LITE -4.95%、$AAOI -4.85%、$SIVE -14.8%、$SOI -5.73%、$AXTI -8.13%、$IQE -12.13%),表明该板块短期波动剧烈,可能受情绪或流动性影响。
  • $XFAB:近期股价波动大,但博主认为1.5亿美元市值被低估;需关注其SiC代工厂产能及客户验证进度。
  • 标的集中:博主持仓高度集中于光子学和AI硬件,若相关主题逻辑被证伪,可能面临较大回撤。

后续可跟踪事项

  • $SIVE:Ayar/Wiwynn合作细节及后续机架部署订单;$MRVL后续CPO产品对$SIVE的拉动。
  • $XFAB:NVDA/NOK评估结论;CHIPS Act资金具体获批时间;SiC/SiPH代工收入增长。
  • $SOI:重组后SOI衬底在光子学领域的需求数据;后续财报指引。
  • 光子学板块:观察昨日下跌是否为短暂回调,是否有基本面驱动的新催化剂(如大客户认证或量产消息)。
  • 博主提及可能分享两支中国股票看法(尚未发表),可关注后续更新。
