Is there any other industry... Where every investor is cheering for shortages and price hikes? SED reported today that: Samsung / $SKHY "stockpiles have fallen to less than 10 days of supply, and a severe shortage could emerge next year, according to a new forecast" KB Securities said that the memory market next year will see "the tightest supply conditions in history" KB Securities projects memory's share of AI infrastructure costs to expand from 40% this year to 57% next year, with others like TrendForce placing next year's figure at 68% (total hyperscaler capex, pretty wild forecast attached) "Both stocks have fallen 38% from their peaks over the past three months, pushing their price-to-earnings ratios based on next year's expected results down to about three times." Likewise, commentary around Phison stated they expect extremely tight NAND supply in 2027, so hard to see memory flooding the market or prices collapsing next year... They gave some color that "soaring NAND prices have forced some Chinese consumer module makers to liquidate inventory, giving Phison opportunities to buy lower-priced stock", so it does show some price declines can coexist with broader shortages. TLDR: KOSPI + read through for other names like $MU / $SNDK might be happy for 2027 given demand causing shortages + infra spend share increase.

So... here's my take on US / China tensions: You have European monopolies like: - $ASML (EUV) - $SOI (Photonics-SOI) - Zeiss SMT (ASML EUV supplier), Trumpf (ASML EUV laser supplier) Japan has many near/complete monoplies like: - TOK, JSR, ShinEstu, Fujifilm for EUV photoresist - 90-100% share - coat/develop equiment with Tokyo Electron -90%+ - actinic EUV patterned mask inspection (Lasertec) -100% share - EUV mask blanks (HOYA, AGC) ~93% share - arf photoresist - Nittobo T-Glass - ABF film (Ajinomoto) - lot of misc from specialty glassAGC, wafer thinning/grinding/dicing with Disco and others. Then there's US allied countries like Taiwan eg. $TSM, Korean memory with $SKHY / Samsung. US has EDA with Synopsys/Cadence, $LCRX / $KLA, $NVDA, and many downstream giants. China has many chokepoints such as gallium, graphite, refined lithium, and others + benefits from cost mass production over many future supply chains (eg. robotics). If I had to give my opinion on US / China supply chain wars: - US is trying to achieve Western independence from China/Russia rare earths + materials supply, but took too long (should have been a priority last decade). - China is trying to eliminate strategic chokepoint dependence and forcing US reliance on Chinese supply chains (as seen with Wf6) It's a race on who achieves supply chain independence first to gain leverage over the other. And fun thing is, AI acceleration kinda throws an unknown variable in terms of speeding up independence. As well as open source efforts (eg. RISC-V), which China is heavily focusing on. So it's a weird paradox where US should theoretically support open source hardware development + open source AI, but it's also being exploited against them. From a Chinese perspective, they're pressuring US supply chains by targeting Japan, which increases Western supply chain reliance on China. And going down the list to eliminate competitor chokepoints internally by throwing subsidized spend into R&D. Or by acqusition as seen with China's acquisition of EU leaders like Ficontec. America... they had all the cards initially, but I think they got too comfortable, and took too long to focus heavily on rare earths (recent funding is a good thing). The earlier tariffs went the wrong way (socks, furniture, other exports), and pissed off allies in EU/Canada too. Which could have been used for leverage for major chokepoints. But maybe they'll realize soon enough why allies are important. Anyway, we'll see what happens, just my two cents about ongoing dynamics. In an ideal world, everyone works together... TLDR: Just some shower thoughts on how there's an unspoken race on who achieves supply chain independence first to gain leverage over the other.

Just an update to my DDR2/DDR3 memory idea with ESMT. They reported August revenue (Taiwan sometimes does monthly reporting): June revenue: ~$153M July: ~$214M August (new): ~$249M vs. $35.3m (last year) Monthly revenue has increased ~63% in two months despite reportedly similar 2026 wafer allocations to 2025 (MoneyDJ report). The profitability is already really high as seen with July's monthly revenue (where they reported ~$109M net income). So if pricing holds, and revenue increases, that would be very nice... Now a lot of US people don't really care since it's in Taiwan, but if you're in the $MU / $SKHY, $SNDK trade. Just educational purposes, it's a second order effect where your leading memory players prioritize AI/DC higher end memory and reduce allocations to older generations (causing shortages). But... DDR4 since prices going up too much, so older gen memory products (DDR4) are getting redesigned with older gen memory (DDR3). And DDR3 products with DDR2. And so on. Causing cascading supply chain shortages. (DDR2 for example is boring/old memory used for cameras, printers, automotive back in the 2000s and not many ppl make them anymore). And even your old DDR2 suppliers like Winbond are gradually withdrawing from the market too... So ESMT is the beneficiary of DDR3/DDR2 shortages. TLDR: ESMT August revenue was ~$249M, up from ~$214M last month.

Just some TLDR news I found interesting: 1. $GOOGL (missed this) also invested in Mediatek alongside $NVDA for their $3.9B raise. Google/Nvidia are goats with investments you look at $SPCX to Anthropic. 2. Samsung Electro-Mechanics discloses $778.9M MLCC deal / $CAPA (new MLCC ETF) also gives exposure now for folks without Korea/Japan/Taiwan market access. But thing is more accelerators x MLCCs per accelerator might indicate a more future extreme bottleneck than people expect. 3. China channel checks state: planetary roller screws, 6D force sensors, and dexterous hands resist domestic substitution. Then planetary roller screw as the top with lowest domestic substitution rate. eg. $SHA0.DE for planetary. Just interesting to hear moats I guess. 4. Samsung reportedly has ~70% of memory production capacity committed through 2031 / commodity DRAM has also fallen into short supply - Seoul Economic Daily. TrendForce expects server DRAM contract prices to rise 13-18% QoQ in 3Q26 SK Hynix also publicly stated the memory shortage lasts through 2030. 5. $CXMT has begun producing HBM3E in small quantities and reportedly claimed mass production of LPDDR6. Implications are even more positive for legacy DRAM shortages. 6. Cisco at SEMICON Taiwan said CPO is ready for mass deployment; pluggable modules will remain the market mainstay. $MRVL also said customers are actively planning scale-up optics deployments as early as 2027 7. Wingtech -> bought Nexperia -> Netherlands effectively removed Wingtech’s control -> Wingtech is fighting back through Chinese courts. But Nexperia got $300m of their assets frozen. More geopolitical drama of course, always entertaining. $AAPl also explicitly accused OpenAI of destroying crucial evidence... (for more fun) 8. Not much description around ASP hikes regarding SOI substrates $SOI, but they now have 10+ customers involved with LTAs, $200m revenue described as a "floor", comments about customers more concerned about obtaining wafers than where they are manufactured. So basically moving into capacity reservation now stages as silicon photonics takes off in 2027. 9. Some channel checks put lead times for high power MOSFETs and large area TVS diodes as high as ~52 weeks. ($STM also reportedly implemented its 3rd 2026 price increase on August 23) 10. Traditional packaging capacity could face a deficit exceeding 20% by 2027" with "wire bonding equipment" emerging as the primary bottleneck", covered this earlier this week with beneficiaries like 11. Claims that all six major ABF suppliers are booked for 2026, with 12-14 month lead times and some suppliers auctioning remaining capacity; $NVDA, $AMD and hyperscalers locking ABF capacity through 2028 and pushing suppliers to plan 2029–30 expansions. Names like Kinsus (3189), Unimicron (3037), Nan Ya PCB (8046), Ibiden (4062), etc are all probably happy. 12. CCL leading laminated board products increased by another 10%-20%, 7th price hike this year (eg. Kingboard). Industry estimates put the HVLP4 copper-foil shortage at ~48% in 2026 / 43% in 2027, while Low-Dk/T-Glass lead times have stretched beyond 30 weeks. 13. "(GaAs) substrate materials and gallium epitaxial source materials are also facing another round of price increases in the third quarter of 2026, reportedly 5 to 6 times higher than at the early stage of the restrictions." "China has recently eased some substrate export controls" but there's a "severe InP substrate shortage" per digitimes. Just some $AXTI related updates 14. $AMD and $AVGO reportedly booked most of Powertech's planned FOPLP capacity ahead of mid-2027 mass production 15. $INTC considering $INTC foundry for HBM4E base dies. But $SKHY responded directly that "some of the content is different from the facts". 16. "OpenAI Hoarding Tens Of Thousands Of $AAPL Mac mini and Mac Studio" for reinforcement learning. Anthropic has been renting mac mini units from $AMZN as well. Kinda sad Tim Cook retired, but dude had a goated run. Just random interesting notes

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.

I'm glad the leverage bros moved from AI stocks back to Hyerliquid and biotech like $MRNA, so maybe we'll see a faster recovery. Aside from that just some TLDR stuff: - $EWY up, primarily from SK Hynix buybacks (they're just too profitable), and Samsung Foundry roughly ~10-15% price hikes. - $SKHY unveils CPO roadmap?? Apparently they're doing something with photonic interposer that links to memory, so I gotta look a bit deeper into this Probably going to be more TAM expansion, more supply chain beneficiaries (eg. lasers, PICs, packaging) off this. - $YMTC pursuing IPO next quarter following CMXT's successful IPO. The Chinese IPO market is just going brrr from Unitree to memory makers. US needs to do something similar rather than IPOing companies at trillion dollar valuations already. - Tyntek limit up there's now order visibility through 2028, given photodiode demand imbalance for photonics. Elazr GM did say the entire optical supply chain was facing major shortages... I'll probably look more at high-end PD bottlenecks next. - MS forecasts a 50% Q/Q price increase for DDR4 for Q3, and 10%+ increase for Q4 2026. (Nanya/2408, Windbond/2344, should be happy). - China reportedly delays clearance from germanium, quartz-based materials, and neodymium magnets To taiwan. So I'll probably have some fun looking into supply chains disruptions there over cup noodles. - High-end PCB drill shortage (still ongoing), Kawei (5498) said AI DCs, servers and optical communications are driving demand for PCBs, HDI and package substrates, while tungsten prices are rising. Though the world's five largest drill manufacturers are aggressively expanding capacity, supply remains far below overall market demand Just stuff I found interesting recently, obviously $MRNA stuff is too.
