Management Deep Dive: Buying a Stock Is Buying a Person

Deep management research on a company (or person company).

"Buying a stock is buying a person. Find someone you trust, then hold long-term." — Duan Yongping

"To judge management, look at what they do when no one is watching." — Buffett

Design Philosophy

Most analysis stops at the surface: résumé, shareholding, compensation. But Buffett spends time talking with management, Li Lu says investing is fundamentally investing in people, Duan Yongping says buying a stock is buying a person.

AI can't have dinner with management, but it can via public information: ① track whether words match deeds (promises vs delivery); ② analyze the return of every major capital-allocation decision; ③ infer character from decisions made in hard times; ④ cross-check via employee / merchant / customer feedback.

Use when: standard research leaves management score uncertain (★★★ or below), or when management is the core investment logic.
