· 供应链分析
涉及标的： $AAOI$AMZN$AVGO$AXTI$DOWA$LITE$MRVL$MSFT$POET$TPU
呃，根据我个人的研究，为了全面覆盖我看好的一切： 1. $AXTI 位于整个供应链的最底端，占据 1/3 的磷化铟(InP)衬底和 1/4 的磷化铟(InP)份额。AI 供应链竟然与这只市值 7 亿美元的股票紧密相连，这完全出乎意料。 2. $DOWA + 住友电气，用于在衬底和材料方面进行西方对冲。 3. $AAOI, $LITE 针对超大规模云服务商的芯片，一家服务于 $AMZN/$MSFT，另一家服务于其他客户但更侧重于 $TPU。 4. $MRVL + $AVGO 我认为这就足以捕捉光子学物料清单(BOM)的价值以及磷化铟(InP)供应冲击。 还有一些其他有趣的标的，比如 Landmark Opto，我正在关注。 $POET 没进这个名单，反正你可以通过 $MRVL 获得敞口，除非我漏掉了什么。
Uhh, from my own personal research so far, to cover all grounds I’ve liked: 1. $AXTI at the very bottom of the entire supply chain + 1/3rd of InP substrates 1/4th of InP. Completely unheard of that AI supply chain is tethered to this $700m stock. 2. $DOWA + Sumitomo Electric for Western Hedge on substrate + materials. 3. $AAOI, $LITE for hyperscaler chips, one for $AMZN/ $MSFT, the other for everything but more levered to $TPU 4. $MRVL + $AVGO I think that’s kind of all you need to capture photonics BOM value + InP supply shock. There’s some other interesting ones like Landmark Opto that I’m looking at now. $POET didn’t quite make that list and you’d be getting exposure through $MRVL anyway, unless there’s something I missed
