- 所以… 回到存储这边我们现在有： $SKHY CEO 表示: “我们预计[存储]短缺将持续到 2030 年底” $SNDK 表示: “我们看到直到 2030 年，NAND 都存在结构性的巨大需求”非 GAAP 毛利率将维持在约 80%. $NVDA 表示 供应承诺从 1,190 亿美元增加到 2,790 亿美元，主要由存储采购推动…与此同时, 存储定价处于“极端”水平 而且还在继续上涨. Winbond 正在与多家客户就延伸至 2029-2030 年的配额展开讨论. 我之前就说过, 存储需求看起来是结构性的, 而现在从传统 DRAM 到 HBM，需求可见度已经延伸到了未来数年.. 所以我确实认为, 整个板块的远期 p/e 倍数都有进一步上升的机会.
- Since people are having fun speculating on $SKHY CPO roadmap supply chains. I'm gonna do my own guess and say SK Hynix is evaluating Celestial/Ayar. Then doing heavy evaluation into microLEDs past first-gen deployments. Both have been kinda working on it for awhile. - Ayar shown up in SK hynix's own website in the context of optical <-> memory links. - Marvell is actively working with SK Hynix in custom memory solutions (and guess who owns Celestial now). Celestial/Ayar are both also cited in SK Hynix's linked Nature Paper, which helps a bit with technical relevance: (121): Stojanovic, V. A UCIe optical I/O retimer chiplet for AI scale-up. In 2025 IEEE Hot Chips 37 Symposium (HCS) 1–22 (IEEE, 2025) - This is Ayar reference (Ayar’s teraphy optical I/O chiplet), Stojanovic is Ayar Lab's co-founder btw. (123): Winterbottom, P. Photonic interconnect for accelerated computing celestial AI photonic fabric module (cough cough Celestial) There's more breadcrumbs out there, but wanted to keep this relatively short-form. For more upstream beneficaries: -> I still think $SIVE is the cleanest read through since they're likely supplying to both Celestial/Ayar. The interposer/packaging IP layer... People were speculating $POET, but Marvell probably vertically integrated players them out this year after the announcement. Given they've had their own SiPH interposer tech/integration IP before Celestials acquisition (eg. presented a silicon-photonics interposer back in 2023) -> AMS Osram (which I don't own), seems like they're co-developing in this area given they randomly went out of their way this year to say HBM <-> optics was a TAM increase for them. TLDR: I see Ayar/Celestial as candidates for SK Hynix's CPO roadmap, then microLEDs being commercialized past gen-1 maybe 2029. (this is all speculation) Just to throw a bone to quantum dot bros, this got cited like 5 times.
- Just some more demand imbalance visibility for $SNDK, $SKHY, $MU, Kioxia, and your NAND players. Phison CEO: "2027 capacity constraints will be even more severe than in 2026." "Upstream suppliers need up to 4 years from plant construction and equipment investment to actual production. With demand growing explosively and supply expansion limited, the NAND shortage is likely to last for years." Don't quite think I agree with the people claiming it's all over for memory, esp. NAND bottlenecks in 2026...
- Did Citadel really just liquidate Situational Awareness… Then brought up entire markets the next day? $NBIS +26.25% $IREN +25.96% $SHAZ +22.82% $SNDK + 23.98% $BE +23.67% $SKHY +16.98% $INTC +12.16% Amid many others. This has gotta be one of the wildest liquidations I’ve seen.
- - Sk Hynix mainly traded in Korea - $SKHY lists in the US with limited shares, ~2.5% of the float (this is called ADR) - Even though SK Hynix are the same company, the shares trade independently. - Sk Hynix US traded at a 20-50% premium to SK Hynix Korean listing due to limited supply, but lot of US demand. -> ADRs allow for conversion between Korea Shares to US Shares, and conversion will start on the 29th - If you convert 22.5% of the Korean supply to the US, that 20-50% premium is likely to go down eg. If there's limited mangos, and someone pays $3 for mangos. You buy the same mango for $1. You keep buying those $1 mangos and selling for $3 until the mangos pricing converge. That's called arbitrage and what likely traders would do.
- For anyone watching the 25%+ premium in $SKHY versus SK Hynix's Korean shares: The ADRs and local shares become convertible on July 29. Should open the door for arbitrage and likely compress the ADR premium. Maybe lifting Korean shares or pressuring US shares. 2.5% currently is the US ADR stock, so an additional 22.5% can be converted.
