$SIVE + Aeva likely coded from the new PR today and SIVE + Apple. For Sivers lasers powering robotics / physical AI. -> Sivers lasers powering Boston Dynamics Atlas via. LG Innotek for robotics -> Nvidia Hyperion ecosystem w/ Sivers lasers for physical AI. Are possible paths with Aeva. Apple likely using Sivers also reiterated from the newer webpageοΏΌ: β€œOptical sensing modules for wearables” from biometric and health monitoring. They just can’t namedrop partners due to confidentiality, but consumer sensing is probably the biggest tell. Physical AI and mass consumer production with Apple would be very material to revenue.

$XFAB upgraded to outperform with a PT of €12.8 by Bernstein, up from €5. Okay I forgive you Bernstein for Kioxia and Intel. I still think that’s just reactive PTs off automotive recovery, SiC/power semi ramp up. And undershooting potential a lot… If markets price in the possibility of xfab moving to HVM. On their silicon photonics foundry w/ photonixfab / Nvidia + LIGENTEC for TFLN on SOI. Regardless I’m bullish too on XFAB and curious where it heads.

There’s nothing like BoFA giving BS extreme bear predictions. To clear all the Korean leveraged traders a 2nd time this year. Korean markets are less resilient when it’s built on Aespa, Salmon skincare, and SK Hynix/Samsung memory names ig. https://t.co/84FpyHX0kC https://t.co/d5INusRVQN

Bank of America looks like the malicious equivalent of Bernstein/Jim Cramer to retail. - said $KOSPI / $EWY was an extreme bubble, compared it to Silver crash back in March, causing retail to sell positions. The index proceeded to close to double and hit ATHs since that call. - saying β€œBoA expects 3 rate hikes in 2026”, Close to 0% chance on derivative markets and causes retail panic. While Trump administration calling for rate cuts. Absolutely harmful behavior from a US bank publishing this garbage to retail investors.

@TradingTh3Trend This is likely just a PR to support $SIVE + $AAPL relationships to combat false short seller claims the relationship was terminated. They've likely been working with Apple for quite some time, not really entering the market.

@SaiseiInvesting No, 0 clue why people invest in those types of ETFs. - You have the most basic names you can buy yourself like $LITE / $COHR as heaviest weights, where they take management fees. - Names not adjacent to AI DCs.

IMO photonics theme + CW laser chokepoint is goated. It's legit like markets have short term memory loss and forgot how $LITE went from $3B -> $65B+ from 2024 to now. Because $NVDA caused EML bottlenecks, and forced architectural changes. We're literally seeing the same thing today with CW lasers + 1.6T/CPO shifts with Nvidia signing LTAs everywhere. Now, $AMD + other CSPs are hunting for remaining scraps with large LTAs for CW lasers + optical components. GS Research's ~9-10x $154B optical TAM in 2028 and near $0 -> $91B CPO TAM in just 2 1/2 years. Don't just magically disappear from a month of trading volatility. $AAOI sitting at ~$13B, $SIVE sitting at ~$3B, and other CW laser players look strategically very valuable. And next year I think we'll look back and say "Why didn't I learn my lesson the first time with EML from Nvidia and pick up CW laser adjacent names!" Then there's likely gonna be some new mini trend 1-2 years from now like microled or quantum dot and we're gonna see the same thing repeat. Think Sumitomo's projections with CW laser share + silicon photonics being majority / dominant architecture should be correct. I'm personally just focusing on that bottleneck as you've seen with $SOI, $TSEM, $SIVE, and others.

I actually think OE Solutions ($138080.KQ ) makes the most sense as an acquisition target by a large downstream player. Since it’s now trading at a stupid ~$215M MC for scarce EML/CW laser IP. A Source Photonics / Suzhou Dongshan Precision type acquisition might add a lot more value to another company that wants to vertically integrate. Given there’s a lot of expensive R&D and capex required to scale their fabs and buildout ahead + it’s a small optical player. (Disclosure: I do own positions) Just floating the idea out there to other companies.

@JJJJJ_66666 Because I’m comparing thesis timeframes when I said $IREN was dogsht after endless dilution and a GPU pivot from Colo. I had $IREN last year and sold it for $NBIS and others. Turns out that was the correct idea, but IREN bagholders can’t admit it

Wow, $SPCX is now down over $583B in MC... Since Jim Cramer gave a bullish call at $210. Pretty amazing to witness tbh. Inverse Cramer would have returned ~21% in 3 trading days, outperforming a year in your largest indexes? https://t.co/IhNtFAH99s https://t.co/xGiAOImQXE

That’s for you to decide. But just throwing this out there: If $AAOI hits projections, that’s over 800%+ Y/Y growth, and $5.6B revenue annualized off $12.8B MC. My guess is that the $471m/month will keep going up as demand seems to scale exponentially into 2028. I’d expect ASP/margins to go up across the board as well. Especially as the industry is bottlenecked and $AMD + CSPs are going around hunting for LTAs.

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. β€œ80% 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.

Wow, 3 limit ups in a row with WUS TW. Pretty sad I didn't take larger positions. WUS TW is 1 my 2 NAV arbitrage + independent growth trades. If you want context: WUS TW is a ~$1.12B PCB player with AI DC growth. Their stake in WUS Kunshan is $4.79B (11.4% of 42.04 billion) So basically they're a $1.1B PCB player growing independently, sitting on ~$4.79B worth of another company that looks to IPOed on Hong Kong markets soon. And a successful activist investor in Palliser (with Ajinomoto and Toto), is pressuring them to trim some holdings along with a few others. Seems like a pretty insane disconnect, and I think there's a lot of potential here.
