AI supply-chain 'chokepoint' theory: ignore the obvious mega-caps (NVDA, hyperscalers) and instead reverse-engineer the AI buildout to its narrow, irreplaceable upstream nodes — compound-semiconductor substrates, InP lasers, co-packaged optics/silicon photonics, MBE epitaxy gear, power semis — small-cap suppliers the buildout literally cannot proceed without. Likened to choke points such as the Strait of Hormuz for oil.
Top holdings
long — Signature/crown-jewel call. InP (indium phosphide) substrate chokepoint for photonics with claimed vertical integration of multiple upstream nodes; the trade that got him banned from WSB and the one he calls his most legendary (claimed ~1000%+ paper gain).
long — Highest-conviction name; external continuous-wave DFB laser light source for co-packaged optics (CPO) — a chokepoint input as optical interconnect replaces copper. Claimed ~19x.
long — Specialty foundry — photonics + 800 VDC power semis (NVDA exposure via NVTS/POWI), only high-volume SiC foundry in the US; EU CHIPS Act 2 catalyst. His 2026-05-27 post drove a 70%+ rally with no company news (Bloomberg/Reuters-covered) — the clearest proof of his market impact.
