“@yathatone2 They're all kinda high conviction... aside from $MTSI and Win Semi. You can probably just put all those in an equal weighted ETF and strongly outperform the market. There's more laser suppliers/foundries like $GFS, but I chose my personal winners in the list above.” post →

2026-06-27T02:11:30$SPCX / Elon Musk acquires Mesh, an optical networking startup. Which is working on 1.6T OSFP (pluggable). It’s seems they own the optical engine/packaging side of things, but likely sources CW DFB lasers off merchant companies. $SIVE is one of the more startup friendly plausible merchant suppli… · 1790 likes · 657,629 views
2026-06-16Other way around, $NVDA bottlenecked the entire industry for EML capacity. And did the same with CW capacity ONCE AGAIN with $LITE, $COHR, and $MRVL (if they have LTA in place with Celestial) I said this a few months ago, we'd see this exact same playbook. But $AMD, $AMZN, $META, and others are ju… · 174 likes · 26,341 views
2026-06-15T07:25:28Wow, $IQE and $TSEM sign a multi year InP epiwafer deal. Remember I told you all IQE was important to Western optical supply chains back at $12? $MTSI had to go out of their way to secure their supply with IQE. Now there’s another critical deal with Tower Semi. https://t.co/4A5PAuA3PU · 997 likes · 445,970 views
2026-06-15Ayar 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, … · 162 likes · 18,318 views
2026-06-12T07:22:33+00:00VPEC new price hikes on Epiwafers today. Positive bottleneck read through on companies like $IQE and Landmark (3081) in terms of pricing power/demand for epiwafers. This follows $MTSI investment into IQE to secure capacity, and shows how important some of these chokepoints https://t.co/EeOR3HjzPV · 577 likes · 453,336 views
2026-04-23Win Semi handles expansion… that’s why I was bullish on $SIVE so they don’t need to burn through capex handling this. There’s only a few publicly traded companies in the world that can do this and they’re all in the tens of billions. There’s a reason $JBL selected Sivers in specific. Same with Aya… · 99 likes · 9,737 views
2026-04-23All the hyperscalers $SIVE likely ends up in 2027-2028 is staggering at a $900m MC. Markets don't understand what's coming. From speculative mapping: > $SIVE -> $POET -> $MRVL -> 1. $AMZN (purchase agreement/warrants with photonic fabric from celestial) 2. $MSFT (maia) 3. $GOOGL (recent dev… · 2152 likes · 465,760 views
2026-04-21Woah... Sivers looks like the primary laser supplier to $AMD's CPO program if AMD goes the Ayar route at $GFS. The interesting thing is: $LITE and $MTSI were silently removed from Ayar's website sequentially over time. (Special thanks to one of my followers Setian for the DM.) So $SIVE likely be… · 1162 likes · 438,706 views
2026-03-26Photonics are not having a fun time. Laser Companies from: $LITE, $SIVE, $COHR, $MTSI, $AAOI all down. Substrate, Foundries, and Epiwafer from: $IQE, $AXTI, $SOI, $TSEM all down. Almost everything is red. From 6% on lower beta like Coherent all the way to to 22%. Good lesson to learn: Embr… · 840 likes · 134,574 views
2026-03-26So if you care about the second optical transicever bottleneck outside of EML/CW Lasers: - $SANM (US) - $TTMI (US) - WUS Printed Circuit (TPE: 2316) - Unimicron (TPE: 3037) - Zhen Ding Tech (TPE: 4958) - Gold Circuit Electronics (TPE: 2368) Were winners for the optical transceiver PCB bottleneck.… · 282 likes · 88,535 views
2026-03-26@Alex__0x0 Yeah, everything from $AAOI, $LITE, $MTSI, $TSEM, $COHR, $AXTI, $SIVE, $IQE, Landmark, and others have been strongly outperforming!. Sometimes you forget the index is down -4% YTD. · 37 likes · 6,559 views
2026-03-26$SIVE at ~$400m MC is a name I genuinely believe... Institutions missed as the upstream laser chokepoint for hyperscalers. When you look at $TSEM following my thesis, the stock went up 70% to a $21B+ MC. Retail flows do not send NASDAQ stocks up $10B+. Information discovery and synthesis does. E… · 467 likes · 67,576 views
2026-03-26@Berlinergy Exactly. Lot of things come just a lack of understanding. If people developed their own conviction around names like $SIVE, $MTSI, $LITE if they saw how severe the EML/CW bottleneck is going to be. Then when you see a 125%+ increase, you would still think it's undervalued. · 27 likes · 4,363 views
2026-03-25@rodrimartinezgg Trading at ~$440M right now but my expectation is $2-3B today. Then could be $MTSI $17-20B MC in a year and half once Jabil and others scale up. · 31 likes · 4,993 views
2026-03-25@TGodTrader Oh 100% companies would want to acquire Sivers. They're one of the few companies in the world like $MTSI that can do this. But acquisitions might be blocked since $SIVE is central to national security for both Europe and US (CHIPS Act recipient). · 43 likes · 6,752 views
2026-03-25@yathatone2 They're all kinda high conviction... aside from $MTSI and Win Semi. You can probably just put all those in an equal weighted ETF and strongly outperform the market.

2026-03-25Every industry leader... Especially $AVGO (Physical Layer Products division) in this statement today. Cites Lasers as a bottleneck for semiconductors. If you aren't long... -> CW Lasers: $SIVE | $MTSI -> EML Lasers: $COHR | $LITE -> or their foundries in $TSEM/Win Semi Maybe it's time to wak… · 729 likes · 279,979 views
