$SIMO

Does he own it?

He states first-person that he took a position in SIMO on the day of his thesis post (Feb 18), then repeatedly lists it among his personal longs in subsequent recap/return tweets. No explicit portfolio weight is given, and it sits within a broad memory/AI-supply-chain basket rather than as a concentrated holding, but the buying language is direct.

His thesis

SIMO is a backdoor/asymmetric play on the NAND and AI-memory supercycle. It operates as a near-duopoly (with Phison) in merchant SSD/flash controllers, supplying all major memory makers, with ~50% gross margins, strong revenue growth, net cash and no debt. Memory makers outsourcing controller work as they pivot to HBM expands its share, and new shipments to a leading AI GPU maker (likely Nvidia) for enterprise boot drives add high-margin TAM growth.

How his view evolved

Began as a researched thesis plus same-day position in mid-Feb. View stayed consistently bullish; later tweets just celebrate it as one of many longs that surged 100%+, noting it climbing toward 10x territory. No thesis change or trimming mentioned.

Key points

• Took a position the same day he posted the thesis; later lists it among personal longs
• Duopoly controller supplier riding NAND demand plus AI enterprise-storage TAM expansion
• One name in a broad sector-rotation basket; no stated weight, treated as a winning trade
