- Lot of critiques are from people who don’t understand how to evaluate qualification cycle semi players. Got the same thing with $AAOI back at $30 or $AEHR at $30. Goes to show when people look hard into development contract revenues, one-off accounting charges, rather than how hyperscaler supplier qualification timelines are going
- @Finishurbkfst23 Because they're qualification stage. Same thing with $AAOI or $AEHR before their volume inflections. It's just understanding semi ramp cycles from development -> qualification -> volume ramp.
- You can look at the YTDs for: - $SIVE, $IQE, $AXTI, $ARM, $MRVL, $INTC, $SOI, solana:NBiSF3UaVUFtRzHwAfxyHsBCAZWGEKnMpewAE4oh7BG, $AAOI, $LITE, $EWY, $TSEM, $AEHR, $RPI, $MU that I did took positions on earlier in the year or last year. Then let me know if you still think that way.
- $AEHR receives another $22M follow on order for AI processor wafer level burn in systems. By their lead AI processor company. It’s cool to see this tiny company grow up so fast across so many verticals (memory, silicon photonics, etc). Up +5.39% premarket off the news. https://t.co/YkOtELzkmo
- I’m not sure if you’re aware but the entire AI sector is dropping indiscriminately right now. A $1T company like Samsung is down -26% this month. $MRVL is down -31%. So higher beta names tend to move a lot more like $AAOI and $SIVE with their 50% drops. But recoveries tend to be a lot more volatile like $AEHR 50% single day gain after ER.
- I don't see any fundamentally wrong. There's probably going to be large corrections from time to time flush out margin/leverage before things move higher. And this month seems like that time of year? $POET confirmed your big optical giants like $LITE, $COHR are completely sold out for the next 2 years, and likely into 2029 for photonics. Innolight confirmed 800g transceiver upward revisions 3 days ago, so that should be positive for $AAOI and the others. Samsung became the most profitable company in the world, and continues to project DRAM hikes for future quarters. $MU signed 16+ LTAs showing memory demand is structural... $META + hyperscaler capex plans are on the higher end of projections. I wouldn't conflate short term price movements with longer term trends. And as seen with $AEHR, recoveries tend to be extremely fast (eg. 1M of corrections wiped out overnight).
- It's nuanced, $AEHR implications was more toward broader silicon photonics related ramp. Which could include 800g/1.6T pluggables, or CPO. If they directly named CPO, Msscorps would be a very clean readthrough. It just got hit really hard recently from that delay claim (even after $NVDA refuted it), since it's it's upside seems tied to CPO yields in specific. So it's positive, just uncertain.
- $AEHR back up +36.4% today off earnings! 2027 guide: $130-$150m (160-200% growth) from 2026 revenue. Sees opportunity to guide higher (assumes no memory revenue or little to none from newly benchmarked AI customer). Q4 bookings: $60.7M, effective backlog is $100.6M. - Lead AI processor wafer-level burn-in customer is significantly ramping their products. - Engaged with additional AI processor customers who are evaluating wafer-level burn-in. - Benchmark customer, which was a “major supplier of AI accelerators, CPUs and network processors” “exceeded their expectations. From management: The potential revenue opportunity from one of these devices is "significant to Aehr". So another benchmark win for potential HVM in the future. - Wafer level burn-in benchmark with a "global leader in NAND flash completed". Now evaluating a development agreement for HBM/NAND Seems like $SNDK since there was HBF related discussions from last quarter I think. - "Our package level burn-in business for AI processors also gained momentum over the year … from our lead hyperscale customer for Sonoma systems" - Silicon photonics customer already ramping, newer networking customers has forecast additional systems Basically the amount of global semi companies that map to $AEHR is pretty ridiculous across silicon photonics, memory, AI processors, and others. I don’t quite think that $130-$150m guidance is representative of actualized revenue for 2027 if these hyperscalers/semi companies convert to HVM. Typically with these types of qualification into HVM players, markets don’t really judge it by current quarter, but what’s to come. And it looks very positive so far in terms of reactions... $116 -> $60 -> $94 all in the span of a month is pretty insane volatility tho, so good to know what you're holding.
- This is the average visual TA bro, takes a 50% 50% coinflip: If it goes the other way, they say "ABC Pattern Invalidated", should have known... If they get the coinflip right, they promote their $40/month chart. -> People drawing swiggly lines over KOSPI mean nothing where it heads. When it's primarily Samsung/SK Hynix and forward operating income growth from DRAM/NAND. -> The swiggly drawing over $SIVE, $AEHR, and others mean nothing. When it's primarily hyperscaler suppliers, thematic premiums, and volume ramp orders determining valuations. Then if something randomly goes from $1 to $60 like $AXTI, they claim they spotted it with their "Golden Egg Dragon Candle", while ignoring anything with InP substrate and otpical demand. There's rare times like these where it's a massive sector drop all together. But now the TA bros are showing up everywhere saying here's a $40 course on how they predicted it with swiggly lines.
- Always a fun time seeing semi markets crash from Bloomberg report framing once again… UBS analyst on $META report: “this is not new news”. Regardless: $AEHR down -18.3% $AAOI down -17.13% $SIVEF down -15.4% $SNDK down -14.8% $TER down -13.8% $GLW down -11.4% $MRVL down -11.2% $LITE down -10.2% $NBIS down -7.8% Getting PTSD from Bloombert’s previous misleading report on AMD/Nvidia global export controls earlier this year that crashed semi stocks. FYI: Meta doesn’t randomly buy $48B+ worth of neocoud contracts if they overbuilt capacity and can cut capex… Markets are stupid sometimes.
- As for $LPK: Maybe $3B-$5B seems reasonable when they fully volume ramp if I had to guess. Feels more asymmetrical to me personally since it's just a waiting game and they have the customers for glass substrates. Small machine supplier chokepoints usually cap out from TAM though and don't go to $20B+ unless you're ASML or hold many chokepoints like KLAC. Not many dominant "monopolies" like these out there right before volume ramp this small: Maybe you have stuff like: - Aixtron (MOCVD) ~$8B - Towa (compression bonding) ~$2B - Techwing (memory handler/cube probes) ~$1.5B - MSScorps (CPO inspection), but pre-ramp. $850M - Riber (quantum MBE), very pre-ramp ~$350M Then LPK Laser for glass core substrates (about to ramp) at ~$730M, which thematically should have more premiums than memory. (eg. major advanced packaging shift, CPO adjacent, etc). Lot of obscure chemical monopolies I know of, but those don't get as much attention cause BOM is much lower than equipment. But for lpk you have: eg. “80% of customers among major global players have selected LPKF equipment”. 70% of LIDE market share target for TGV in the glass-core ramp, should be very material. (disclosure: own, the listed names above aside from techwing/aixtron, NFI). Just kinda the path they go if you follow $AEHR at ~$3.5B now: - <$500m: "Oh they have no customers!" ---> (probably somewhere in the middle here). - < $1.5B: "Maybe volume comes soon!" - $3B+ onward: "Looks like they're starting to volume ramp. Just a lesson for the cycle of the chokepoint machine suppliers from my personal experiences.
- So short term ramp, I see $LPK probably might be more parabolic. Since when equipment suppliers switch from qualification to volume production as seen with $AEHR or $AIXA recently, they tend to get re-rated to $3-7B MCs. But 99% are structurally more capped on where they head. Long term, I personally see $XFAB has much much higher upside if they're able able to lead European's photonic supply chains and build out a $TSEM alternative with MTP. But are earlier on in the process.
- $AEHR receives follow up production order from major Silicon Photonics Customer for wafer level burn in systems. Now up 11.29% today to $116. Only 2 months ago it was in the $30's, good times. https://t.co/It24lVLmBe
- @AsianbeBlazin Yep, but there hasn’t been any much news with $AEHR. Not really heavily debated stock like $AAOI aside from one or two comments saying AEHR would go back down to $25.
- Ayar started off multi-sourcing with $MTSI and $LITE. Then removed them from their website and likely made $SIVE primary source (likely for first gen). It's every hyperscaler supplier intention to multi-source, there's nothing material being added there. Ayar is one of the bigger CPO players, but if CPO mapping is correct more revenue should come from $MRVL Celestial, maybe Lightmatter/Lightelligence. Ayar is also just one customer of many... This is not even including $JBL + other pluggable players that use $SIVE. Or even O-Net producing ELS with $SIVE for Asian supply chains. Nobody can accurately estimate revenues right now, it's just that they've been qualified into so many different hyperscaler supply chains like what I've done previously with $AAOI or $AEHR. That when volume ramp happens... And it's a hyperscaler supplier, you expect revenue numbers to be extremely material.

Ignored the clearer irrelevant stuff like $POET that people mentioned tho. There's like 500 comments, but I guess X limits everything I can see. We'll see how your highest conviction ideas do.
- Good times with $AEHR, it’s now ~$3.5B MC. Haven’t mentioned it as much since there’s nothing too new. Just waiting on volume orders for these types of players like $LPK, and others. https://t.co/W8k0ce3RSE
