$GFS

Does he own it?

No first-person buy/hold/add or weight statement for GFS. It appears only as supply-chain context. One list including GFS says he owns "most, not all"; a later list including GFS explicitly limits his stakes to NBIS/TSEM/AAOI, affirmatively excluding GFS. Earlier he framed GFS as a possible dip-buy idea, not a position.

His thesis

GFS is treated as a key US silicon-photonics/CPO foundry and a recurring node in his supply-chain maps. Its main role in his narrative is as validation for his real conviction pick (Sivers/$SIVE): GFS's webinar slide listing only two public laser suppliers, plus an AMD CPO partnership routed through GFS, supposedly confirm Sivers' laser inclusion. GFS itself is discussed positively but mostly instrumentally, as ecosystem confirmation rather than a standalone bet.

How his view evolved

Starts as a generic dip-buy/foundry idea amid tariff news, then becomes a fixture in CPO landscape lists. From April on, GFS matters mainly as the "validator" of his Sivers thesis (slide listing laser suppliers, AMD CPO deal). Never elevated to a disclosed personal holding.

Key points

• Recurs as a CPO/SiPh foundry in mapping lists, not as a championed standalone position
• Latest holdings disclosure including GFS limits his stakes to NBIS/TSEM/AAOI, excluding GFS
• Bullish framing is instrumental: GFS slide/AMD deal used to validate his Sivers ($SIVE) thesis
