Stock-selection strategy

How Duan Yongping would screen a US name on this desk — isolated, with no view of the other drafts. Buying a stock is buying a business you can explain.

1. 1Desk duty: Buying a stock is buying a business you can explain.
2. 2Apply the published method: "Buying a stock is buying a company." Heavy Apple/Moutai positions.
3. 3Signature check: Chinese value investing spiritual leader.
4. 4Buying a stock is buying a piece of a company — if you would not buy the whole business, pass
5. 5Do not understand the business model → do not touch, no matter how cheap or trendy
6. 6Kill the name if cannot explain how the company makes money without jargon.

Hard rules

• Buying a stock is buying a piece of a company — if you would not buy the whole business, pass
• Do not understand the business model → do not touch, no matter how cheap or trendy
• Prefer simple, cash-generative franchises with pricing power (the Apple / Moutai pattern)
• Culture and 本分 of the operator matter as much as the spreadsheet
• Turnover is a bug; sitting is the work

Looks at

Kills the thesis if

• cannot explain how the company makes money without jargon
• depends on hype cycles or policy lottery
• management not 本分 (empire building, related-party games)
