跟踪 Serenity 的最新研究

Got curious and decided to track which thesis of mine were still up 100%+ YTD after the recent drawdown: 1. $AXTI - InP substrates 2. $NBIS - Neoclouds 3. $MU - Memory 4. $INTC - Foundry 5. $LITE - Photonics 6. $IQE - Epiwafers 7. $AAOI - Photonics 8. $GDRZF - Venezuela 9. $AEHR - Machines 10. $EWY (volatility + underlying) 11. $RPI - AI orchestration 12. $SOI - SIlicon Photonics Substrates 13. $SNDK - Memory 14. $SIMO - Memory 15. $MRVL - ASICs 16. Nanya - memory 17. Unimicron - substrates 18. $ARM - CPUs 19. $SIVE - Photonics From H1 2026, around 19 names across several themes up 100%+ still from the selection of winners. Since many like $TSEM / $HPS.A / $LPK / $ALRIB fell out of the range. (obviously not all are green like Shunsin / $XFAB and disappointed by performance). Regardless, glad a lot of my ideas turned out decently, rather than just being known for one like $AXTI. To the point the Chinese community gave my investing style a name "Perilla Leaf Theory". Again not too sure if my new ideas replicate this performance again in H2 2026 or 2027... For H2, my new thesis was on $CCXI for humanoids/downstream physical AI shift and ESMT for DDR2/DDR3/legacy memory. But I'll keep sharing my core ideas and thought process for free so people can poke holes or debate it until things get validated.

China reportedly halts some rare earth shipments to US. Not a new blanket ban, or any mention of specific rare earths. But… if I had to guess, Japan is usually a decent indicator of what’s actively important since Japan: - “sources virtually all of its dysprosium and terbium from China.” - gallium, dysprosium, terbium and yttrium from China to Japan all stood at “zero” in June. - Shin-Etsu Chemical has reportedly suspended acceptance of new orders for magnets containing dysprosium. - Global magnet producer Proterial had received no export licenses for Chinese dysprosium as of last month The Reuters piece mentioned yttrium, gallium, terbium, indium phosphide, and tungsten as historical examples (doesn’t say what’s being targeted now). On a side note, $LYC.AX is becoming one of the most important alternatives, as Japan has locked up 75% of Lynas’s medium/heavy rare-earth output. (8 tons of dysprosium + terbium in Q1) Something fun I also read is that Japan’s deep sea resource is enormous (est. at 16 million tons of rare earth rich mud, but commercialization is post-2028) But in the meantime, China seem to be choking off feedstock that would materially affect Japan. Since you’ve already seen the WF6 Japanese industry stressed from tungsten related halts. And indium/others earlier this year that is used to make InP substrates from Sumitomo/JX. But still gradually allowing exports directly eg. $AXTI -> $LITE to allow US/China trade to continue, kinda disrupting that from time to time, then using that as leverage. It’s interesting since Japan has so many different monopolies like ABF, so we’ll see if they do anything back. But if I had to give a prediction, it does look like the US has a countdown timer until China becomes self-sufficient on semiconductors. TLDR: - rare earth disruption to US - China actively targeting Japan for upstream feedstock (which goes to Us supply chains), probably want to focus on that - many many second/third order effects from disruptions - we’ll see what US/Japan wants to do back, but supply chain wars are being fought upstream.

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

It’s been a little disappointing to see a pattern with some people I've interacted with on X: - try to engage with the same audience, then quickly move toward aggressively monetizing it - get upset when I choose not to participate in or amplify paid groups - throw out personal or illogical attacks and try to reframe that as simply disagreeing over fundamentals When I first joined X, a lot of finance content revolved around watches/private jets + options, paywalled communities promising the "secrets of Wall Street," and squiggly-line charts. One of the things I've wanted to do differently is publish my research and reasoning openly, for everyone. I think this definitely resonated with folks given my follower growth. But of course, this growth can also create friction with people whose business models rely on using X to funnel audiences into paid services or expensive paywalls. My subscription has been $1 for months and will stay at the minimum, despite claims at the beginning I would raise it to $100. All of my core theses are published on the main timeline for free. I could put substantially more behind a paywall. I just don't want to. I just prefer sharing the ideas openly and letting everyone decide for themselves. Many ideas have worked out well: $AXTI, $NBIS, $AEHR, $MU, $INTC, $EWY, $MRVL, $LITE, $RPI, $IQE, $SOI, $TSEM, $ARM, $COHR, and a lot more. Others ran into unexpected industry delays, like $LPKF with glass substrates and Auros with hybrid bonding. Some are still playing out into 2027/2028, including $SIVE, Foci, Shunsin, $CCXI, $XFAB and the broader CPO/humanoid themes. Some are brand new like Etron/ESMT for DDR2/DDR3. And many like $JBL to Murata to $MXL, I just share for fun to see if the idea is right. Not every idea will be right. That's part of research. But I'd much rather have an X where people openly publish the thesis and reasoning so everyone can learn from it. Than one where information increasingly disappears behind $100 paywalls or becomes diluted with engagement-bait noise. Hopefully I can help create a new culture on X rather than amplify the old one.

"Severe InP Shortage Triggers Largest Price Hike Ever" - $AXTI. Suppliers have bluntly stated that "even if you have the money, you still may not be able to get the material" (lol). - Industry sources revealed that InP substrate prices began rising in Q4 last year and was the fourth consecutive substrate price hike. - The latest Q4 hike is expected to be >10%, - Meanwhile, prices for epitaxial wafers made from those substrates have already been raised two times, and the market is moving toward a 3rd consecutive increase in Q4. (I also wrote a thesis on $IQE, which benefits here too). Article states VPEC, Landmark, IET benefits (Taiwan centric reporting). I did predict this last year... The bottleneck is real, but I do have higher expectations for price hikes that comes next. Glad it's starting to play out.

I feel like AI investing is simpler than what people expect. Because $NVDA + Jensen literally tells everyone what's coming. But somehow. Almost every. single. time. Markets dismiss it until it actually happens? Be Nvidia in 2025: Buys up EML and laser capacity. Markets dismissing it: "Photonics is a bubble and like quantum! ____ company is a scam with shady management" 1 year later: $LITE +678%, $AAOI +475.12%, $COHR +260.7%, $AXTI +3,843.9%. _ Nvidia in 2026: Buys up CW/EML capacity with LTAs. 800V shift. Extraordinary explicit about CPO shift. States Physical AI as the next theme. Markets now: "CW players are meme stocks! 800v, CPO is not coming anytime soon, Humanoids are not profitable!" Yeah... We'll see what happens in 2027. I think I'm putting my money on Jensen/Nvidia as the leading indicator.

Yes, I'm still bullish on memory like $MU / Samsung. As I said earlier, markets tend to rotate from bottleneck to bottleneck. This week it looks $AXTI to $LITE in the photonics sector is the focus again. The thing is... the primary thing that changed are the stock prices, followed by some narratives + updates sprinkled in here and there. For photonics: > We already knew $COHR / $LITE lasers were completely sold out for the next 2 years during July's drop. > We knew about demand imbalance from $AAOI from last quarter's earnings calls. Nothing deteriorated fundamentally during July's crash, other than listed price after liquidations. Yet tons of people called $AAOI a "scam" when it dropped to $75, or $AXTI a "scam" on its drop to $35... But are bullish again at $140 or $80, when the transciver/InP substrate bottleneck hasn't changed at all, but maybe even got worse... (eg. draft for US ban on new china optical transceivers, scale up demand projections) For Memory: I'm witnessing a lot of retail capitulation, but the same people I'm seeing were mega bullish after $MU signed 16 SCAs and gave exceptional projections a month ago. Or were celebrating Samsung having the highest operating profit in the world. There's updates here and there eg. Rubin Ultra with memory optimizations (which Nvidia strives for every generation), with prices no longer being hiked way above expectations to the extreme. But the operating income relative to MC is just absurd around current prices, especially memory becomes structural. And the demand imbalance should be even worse next year. People tend to capitulate and follow narratives when a sector drops (eg. Helium/LNG back in Iran war), even if the bottleneck or fundamental situation hasn't really changed much (eg. $SPCX Elon earnings call reiterating memory tightness). I can't tell others what to to do: But $AAOI at $140 and $AAOI at $75 are the same company. Samsung at a $1.5T MC and Samsung at a $980B MC are the same company. Just valuations and narratives (often noise) change, and markets rotate from sector to sector.
