我原本在研究一篇来自 Semianalysis 的文章中关于 $AMZN Trainium 基准测试以及亚马逊供应链的内容。鉴于一些朋友（如 @yianisz）之前曾对此发帖讨论，我决定深入挖掘。亚马逊在扩大 Trainium/Inferentia 集群时提供了约 40 亿美元的支出作为后盾，加上 $MSFT 在 ASIC 集群上的投入，随着行业向 800G 升级，我们很可能会看到更多超大规模云厂商客户。对于一家市值 25 亿美元的公司来说，如此依赖 Mag7 的情况实属罕见 lol。下行风险与积极因素并存：由于激光器在德克萨斯州内置生产，该公司实现了垂直整合（更高利润率）。我看好未来巨大的量增需求，但：关键在于执行，他们必须在不搞砸的情况下建成 800G/1.6T 光收发器。我已经全仓持有 $AAOI，出于风险管理考虑，仓位规模相对较小适中（毕竟它仍是 25 亿市值的小盘股）。我依然更看好 $LITE，但鉴于其本月已上涨 46%，很难进行补仓。
I was actually looking into $AMZN Trainium benchmarks from a semianalysis post and at Amazon's supply chain. And some friends like @yianisz post about it earlier, so I decided to look deeper at it. But it has ~$4B spend from $AMZN as a backstop as they ramp up Trainium/Inferentia clusters, spend from $MSFT ASIC clusters, and we'll likely see more hyperscaler clients as the industry moves to 800g ramp. Mag7 dependency is incredibly rare coming from a $2.5B marketcap company lol. Downside + positive: Is vertically integrated (higher-margins), since it's lasers are builtin Texas. I see just incredible volume demand, moving forward but: the whole name of the game is execution since they actually have to build out the 800G/1.6T transceivers without messing up. I'm fully invested already in $AAOI already with relatively small-moderate position sizing for risk management (it's still a small cap with $2.5B MC). I still like $LITE a lot more, but a bit hard to cost average up on that when it's up 46% this month.
