Thesis that companies solving AI infrastructure bottlenecks (memory/HBM, packaging, servers, networking, photonics, power/thermal) have pricing power to pass on war-driven energy inflation, making them attractive during market corrections; lists names across each category.

Discusses vertical integration in optics, noting LITE/COHR rely on companies like FN while AAOI keeps everything in-house, and asks whether that's a competitive advantage.

Deep dive on FN as the overlooked manufacturing backbone of the optical industry, building high-margin components for LITE, COHR, and directly for NVDA's optical cables; sees it as a lower-ceiling but safer route into the photonics bottleneck. States he is not yet an investor and wants to research further before deciding.

Deep dive on SIVE: gross margins are shrinking due to revenue mix shift toward lower-margin custom products, but revenue itself is growing and the standard/high-margin product pipeline grew 90%. Sees SIVE serving AI compute (silicon photonics/CPO) and SATCOM/5G beamforming bottlenecks via a specialized, supply-constrained niche in high-power DFB laser arrays, avoiding direct competition with LITE and COHR. Views the 65% high-margin revenue target as achievable but slow due to long design-to-volume cycles (3-5 years) and manufacturing yield risk. Not yet a shareholder.

Agrees with an analysis on the photonics transition, noting AAOI, LITE, and COHR have stronger current financials than SOI and IQE, but says SIVE is the one name whose financials currently look promising to him.

Points out that AAOI, LITE and COHR have genuinely rising revenues and gross margins, and warns the reader against chasing other photonics names with weaker fundamentals hoping for the same result.

Thesis post: major tech layoffs (AMZN, META, ORCL, XYZ, CRM, ASML) are being redirected into AI R&D and capex, not signs of weak fundamentals. He is bullish on companies that control the emerging AI infrastructure bottlenecks — memory/HBM, packaging/OSAT, server/rack integration, networking silicon, photonics/optical, and power/thermal/grid — naming SK Hynix, Samsung, MU, ASE Technology, AMKR, JCET, SMCI, DELL, HPE, Foxconn, AVGO, MRVL, CSCO, ANET, Ayar Labs, ALAB, CRDO, COHR, LITE, VRT, MOD, NVT, SU.PA, IREN, NBIS, CIFR.
