2026-07-16T15:35:19+00:00I’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%.

2026-07-06T08:25:00I personally think $SIVE can be the next $LITE. In the past few months alone, we've seen: 1.

2026-07-02@DogUrineCapital This is pretty disgusting to see $MRVL down -11%, $AMAT down -11% to $NBIS down -18% On the bright side a lot of the higher beta/smaller names like $AAOI frontran the drop. So those are faring better https://t.co/OEyJ4YiQQr · 143 likes · 35,851 views
2026-06-26Not really, I personally still think it's undervalued. It's about MC relative to forward revenue potential.

2026-06-21T11:04:51That’s a misconception: $SIVE is the laser supplier for next gen architectures, not just CPO scale up.

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).

2026-05-20@osilayer8 Nah, I'm cheering on $SIVE to become the next $LITE. I didn't acquire positions just for Sivers to be bought out by $MRVL or $JBL.

2026-04-22Oh wow, I missed this. That's probably why $POET is up 20.2% pre-market confirming "far in excess" of purchase orders on top of $MRVL supplier relationships. That translates materially to $SIVE laser production as well. Markets haven't fully priced in either yet imo. · 810 likes · 412,021 views
2026-04-22@scrotum_pensif I still think $SIVE should be valued $2B today and can hit $10B+ next year depending on volume ramp from Ayar, $MRVL, $JBL and others in 2028 They have all the stars aligned right now. · 105 likes · 10,676 views

2026-04-22Woah... $POET is up 20.5% premarket today after a 19.32% gain. Mainly after the CFO's interview confirming they're the direct supplier to $MRVL. I wonder if markets know who the upstream laser supplier is yet? (hint: $SIVE). https://t.co/flfx9NVkxk · 1353 likes · 309,359 views

2026-04-21They're actually doing good work for US institutions encouraging local investors to sell. It was a majority retail-locally owned stock.

2026-03-26$SIVE at ~$400m MC is a name I genuinely believe... Institutions missed as the upstream laser chokepoint for hyperscalers.

2026-01-23저도 비슷한 생각입니다! Celestial은 꽤 오랫동안 $POET 와 함께 빌딩해왔는데, $MRVL(마벨) 하이퍼스케일러 백도어 소식까지 더해진 현시점에서 그것이 가장 큰 리스크 완화 요인(de-risking factor)이라고 생각합니다. 다만, 이 종목은 일종의 '문샷(moonshot, 대박 아니면 쪽박)'에 가깝습니다. 자금 조달 이후 재무 상태는 탄탄해졌지만, 시장에는 이보다 더 비대칭적인 수익 기회(asymmetrical plays)를 제공하는 종목들이 분명 있을 겁니다. · 66 likes · 16,304 views
