@aphexinvests I’d expect $SOI, $XFAB, $IQE and others in the European supply chain to play follow the leader and recover as well.
Everything got sold off with photonics / power semis recently.
$SOI$XFAB$IQE
Glad optical players from $LITE to $AAOI and $SIVE are slightly recovering as they should.
The initial selloff was just stupid.
$LITE$AAOI$SIVE
@veggiepoultry That’s correct with $SIVE and Blackrock after MSCI/nasdaq. Blackrock is passive and tracks sivers based on MC.
Fidelity Research is their active investment arm, so that’s not passive.
$SIVE
@oops1GSP Bro everything has technical obstacles. I can bear post about HBM4 yields or glass substrate yields and basically everything too.
$NVDA is a $5T company, they’re not $ASTS.
I’m sure they know timelines and difficulties, so projections should be accurate.

@lumingxi2025 No, $NVDA denied reports about 800v and CPO delays.
I think I’ll trust Nvidia… since they probably have an idea on their own timelines…
$NVDA
Morgan Stanley: $NVDA has denied the reports 800V DC has been pushed back.
Recent SemiAnalysis reports run contrary to our own checks at Computex.
Bro this has gotta be the dumbest CPO/800V selloff I’ve seen.
Since the selloff from their claim $MU had 0 share of Nvidia HBM4 https://t.co/YX9apQSVLT https://t.co/SZp7TBNVMU

Yep, Blackrock has now entered $SIVE positions as passive owners following index listing.
Fidelity Research has shown up as starting direct positions of Sivers too.
Remember when JP Morgan showed up last month with small positions…
Then bought ~5.25% of the company?
This looks like US institutions validated Sivers’s position in photonics and are trying to accumulate positions.

If you want a TLDR of today:
> be $NVDA, $5T company. Force shift to 800V DC and CPO
> analyst: I don’t think u can do it in time!
> market: “I don’t trust Nvidia, time to sell everything”
> Nvidia and Lumentum executives after: Bullish on CPO, timelines accelerating.

@xnoahwang Imagine being $NVDA, the most powerful company in the world, with high visibility of their own timelines, saying there’s no delays.
Then external analysts go and say every architecture Nvidia is doing is gonna be delayed by awhile.
Yeah… I’m going long with Nvidia here.

$LITE Management Speech from Mizuho Technology at today’s conference.
The company expects to start shipping CPO scale up optical products in the second half of 2027.
With formal ramp up in 2028.
No delays, as this aligns with previous timelines shared.
So today, we also got confirmation from
$NVDA SVP no delays on CPO scale out timelines H2 2026, and they’re beginning mass production.
And $LITE management also stated no delays on CPO scale up timeline.
The leading companies in Nvidia and Lumentum probably know their own timelines the better than incorrect analyst reports telling them no.
And both are incredibly bullish on TAM and opportunities.

$LITE Management Speech from Mizuho Technology at today’s conference.
“For the first time, they systemically outlined the roadmap” for the next 3-5 years.
- “The company expects to start shipping scale up optical products in the second half of 2027 with formal ramp up in 2028”
- “This aligns closely to long term framework $LITE previously shared”
Today we got confirmation from
$NVDA SVP no delays on their scale out program H2 2026.
And $LITE management no delays on H2 2027 into 2028 volume ramp scale up timeline.

$NVDA Networking Senior Vice President refuting recent analyst reports on delays:
- “ the most exciting stuff is co-packaged optics.”
- There is no delay in H2 CPO product delivery schedule.
- CPO switch will enter mass production and begin ramping up customer deliveries as planned in the second half of 2026
This was a media article, original interview source credit should have been credited to Tae Kim / Computex.
Something fun to note too was this quote “Gilad was VERY enthusiastic about the CPO ramp from Nvidia.”
Both near term and long term.
Yeah… I’m extremely bullish on CPO alongside Nvidia.
$NVDA
I’m just sharing what’s imminent with architectural shifts pushed by $NVDA.
Retail managed to completely frontrun institutions on multiple names, but institutions need liquidity to enter.
It’s just interesting how every major industry player confirms the same timelines, then a questionable analyst firm that said $MU had no HBM4 share could write a hit piece then be completely incorrect again.
$NVDA$MU
@NathanJoooo This was in response to that erroneous article.
I would trust Foxconn/Lumentum/Nvidia industry projections over an analyst firm that messed up $MU HBM4 so badly and said “no” to all their timelines together
$MU$NVDA$LITE
@Matthew93889052 $AAOI revenues are dominated by pluggable.
These are concurrent architectures happening in parallel, not one or the other.
But maybe past 2029, we’ll likely see some pluggable revenue be cannablized
$AAOI
CPO scale out earlier than expected:
> Foxconn: est. units register upward and optical switches shipped early to $NVDA
CPO scale up timelines from $LITE Mizuho Technology Conference today:
“The company expects to start shipping Scale-Up optical products in the second half of 2027, with formal volume ramp-up in 2028”
SVP $NVDA networking: “We’re going to ramp up CPO second half of this year”. No delay indications.
I’m gonna go ahead and trust industry projections. Where they all reiterate faster timelines for scale out CPO H2 onward. And scale up CPO H2 2027 onward (with main growth happening 2028)
Over a questionable motive analyst firm that said $MU had no share of HBM4 Rubin (causing a selloff)
Where micron went out shortly later to into enter mass production. (Triple digit return shortly after)
I think people going long on temporary bridge architectures from this incorrect report won’t be too happy.
Appreciate the buying opportunity though.

I don’t quite think photonics from $AAOI to $LITE or $SIVE are disappearing anytime soon…
Just extremely volatile.
Anyway, curious what other people are buying today?
$AAOI$LITE$SIVE
@QGrowthCap I mean $NVDA CEO did say memory would be a multi year shortage.
With the way things are going with the nand/dram hikes, all your hyperscalers r gonna be in debt lol
$NVDA
$EWY 32% IV into 58% IV expansion trade.
Into underlying SK Hynix / Samsung increase way ITM.
Was such a goated call? (~383% return)
Had way too many great ideas this year…
Still super proud of predicting South Korea index volatility increase due to memory concentration https://t.co/Kjur1bdKp7 https://t.co/bOADobOLLx

@jim29223471 Can’t give advice on what you should do.
But personally I think $XFAB valuations are a joke at $1.45B MC if they’re leading Europe’s silicon photonics supply chain efforts.
$XFAB
@GalV19634050 I don’t see any signs of capex slowing down, given both Meta and Google just did a raise, OpenAI raised a ton of + going public.
As long as hyperscaler capex keeps ramping, many names above and my other CPO exposure names should heavily benefit.

@super_avg Towa is $1-2B range. $LRCX is a $400B company. $KLAC is a $275B company.
What part of $10–100B range did you miss?
I don’t have exposure to vast majority of names above, just throwing out ideas
$LRCX$KLAC
Names like:
- $ASX
- Sumitomo Electric
- $JBL
- $VICR
- $GFS
- $AAOI
- AlChip
- $TSEM
- $FN
- Furukawa Electric
- $CLS
- $NBIS
- $NOK
- $AMKR
- $LITE
- $COHR
Off the top of my head.
So basically, AI exposure trading in the $10-100B range.
Likely have compelling ROI right now compared to indexes or $ARM to $MRVL that ran quite a bit?
(Just a disclosure, only have financial interest in NBIS/TSEM/AAOI above)
I mention a lot of smaller ideas, but that’s just to chase outsized returns.
Still feels like many of these have room to go.

@TalentActivity I do really like $GFS, $JBL, and others tied with $SIVE.
They’re all just kinda large by now, and less chance to triple.
If I were running a hedge fund I’d pick up Jabil, it I’m personally maximizing returns + don’t like options on higher IV equities.

@bjjkkcjnx @vianebinance There's slander over in the US too! If you try criticizing $IREN or $BKKT you have a bunch of bots/influencers coming after you.
Jealously/lies is a worldwide phenomenon when you gain popularity.
