我们是一支在硅谷的美研投资团队,成员来自斯坦福、UCLA、沃顿。但比学历更重要的是:我们白天就在硅谷一线大厂做 AI 推理与训练,晚上研究的,恰好就是我们白天亲手在用的东西 文章目前发在小红书,X 刚刚建立,后续会同步过来。欢迎前往查看 因为我们本身在硅谷做 AI 一线推理和训练, 年初至今的回报率 YTD+130% 了,按照我的策略走,下半年会有不错的表现。 为什么起这个小红书名字,代表了我们的哲学: 不追一天的涨跌,只看长期逻辑是否成立。看懂再投,看不懂就等 我们只研究一条主线 AI 算力的长期传导。顺着这条链往下数,至少七层: AI 训练 → 推理 → 光模块 → 互连 → 存储 → 产业上下游 这是我们长期跟踪的方向 · 算力工厂 / 新云:ORCL、CRWV、NBIS、IREN、AMZN、GOOG、MSFT 定制 ASIC:AVGO、MRVL、GOOG、AMZN、TSM 光模块 / 光互联:COHR、LITE、AAOI、MRVL、CIEN、FN 机架内互联:ALAB、CRDO、MRVL、AVGO 内存与存储(KV Cache 分层):MU、SNDK、P、NETAPP、RMBS、WDC 推理新品类:CBRS 相比于网上的各路大神,说一些看不懂的话和激进的喊单,我更喜欢保守的策略 1. 永远储备将近 30% 到 40% 的现金 2. 不跟风,只投看真正看透、看懂底层逻辑的AI 3. 不在乎一天的波动,目标永远是 6 个月和一年之后 这段时间把年初至今的文章都整理了一下,回顾下来,重读发现很有收获 欢迎关注我的 X 和小红书,小红书的 ID 也是x id 后续文章会往 x 录取搬运

Okay my fellow Koreans, it's been awhile. Foosung (093370, ~$1.2B MC) looks like a massive beneficiary soon. Basically China export controlled Japan, causing their WF₆ supply chain to go down. Meaning 25% of the world's supply required for SK Hynix, Samsung, $TSM go bye bye. If you remember the Straight of Homuz with Oil, that's a lot. Foosung's importance just shot through the roof given from some est. they're 10% of the supply chain? So that number goes up, massive bottleneck for demand. Then this looks like the best pure play beneficiary outside of China (even if precursors pricing are rough). Don't have positions, just wanted to publish an idea.



Rosenblatt InP lasers checks: According to our checks, NVIDIA, which is the driving force behind scale up CPO, asked the supply chain to increase InP laser capacity by ~20x from 2025-2030. The vendors appear to have taken a more conservative stance, agreeing to an ~12x increase ( $AAOI / $LITE etc)

holy shit😭 这是要干掉几百家公司的节奏啊Σ(゚д゚;)
