$KLAC

Does he own it?

In the one tweet with an explicit ownership disclosure (AMKR, AEHR, ONTO, COHR, TSM), KLAC appears in the same list but is deliberately excluded from what he owns. Elsewhere he explicitly sets KLAC aside as a big, well-known name he is not focusing on. No first-person buy/hold/add/size language anywhere.

His thesis

KLAC is cast as a key beneficiary of AI/semiconductor supply-chain bottlenecks, specifically defect/yield inspection for advanced packaging, SiC interposers, and glass substrates. He treats it as a structurally well-positioned mega-cap inspection toolmaker (alongside ONTO, CAMT) that institutions are buying, but a mainstream name rather than a hidden gem he is hunting.

How his view evolved

Consistent throughout: KLAC shows up only as one entry in evolving supply-chain maps (HBM/memory, SiC, advanced packaging, glass substrates). From start to finish it is framed as a known large-cap he flags but deprioritizes versus lesser-known picks; no shift toward personal conviction or position.

Key points

• Named repeatedly as an inspection/yield beneficiary of AI semi bottlenecks, never as a personal holding
• Explicitly excluded from his own-position disclosure in a tweet where it is listed
• Set aside as a big, well-known name; his real enthusiasm sits with memory/photonics and smaller upstream picks
