$TSEM
tower semiconductor9/10Does he own it?
Repeated first-person ownership: explicitly states he is long Tower, references "my positions," "the moment I go long," and buckets it under his "high concentration (safer)" core photonics holdings. A late explicit disclosure confirms financial interest in TSEM. No numeric portfolio weight ever given.
His thesis
Tower is framed as the "TSM of photonics" — a pure-play silicon-photonics/CPO foundry and his safest, defensible compounder in the photonics supercycle. Bull case: ~70%+ of SiPh capacity already booked through 2028, an NVIDIA architectural partner, compressed forward P/E (~16-18x, lower in growth scenarios), and obscurity as an upstream player. He sees CPO ramping H2 2026 into 2027-2028 as the catalyst driving a re-rating to premium valuations, with foundry capacity squeeze flowing upstream to his other names.
How his view evolved
Started as a passing supply-chain mention, then a high-conviction long entry mid-March near ~$110-115. Through spring he repeatedly took victory laps as it doubled past $250 on earnings/capacity prepayments, and increasingly used it as the benchmark "safer" anchor versus higher-beta picks.
Key points
- Self-described safest core photonics holding; the foundry layer of his book
- Thesis hinges on booked SiPh capacity, NVIDIA partnership, and cheap forward P/E
- Late explicit disclosure confirms he holds it; no numeric weight given
