# 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. ## Step 1: Identify Key People Use `web_search` / `get_stock_profile` / `get_sec_filings`: | Role | Name | Tenure | Background | Shareholding/options | |------|------|--------|------------|----------------------| | CEO/Chairman | | | | | | CFO | | | | | | Founder (if not in role) | | | | | | Actual controller (if different from CEO) | | | | | | Other key executives | | | | | **Distinguish "who decides" from "whose name is on the title"** — some founders remain the soul even after stepping down. Then gather four data categories (sequentially via `web_search` + `get_stock_news` + `get_financial_statements` + `get_sec_filings`, or `run_swarm`): ① CEO public statements and prediction record; ② capital-allocation decisions (M&A / buybacks / dividends / new business); ③ governance and compensation; ④ side validation (employee / customer / industry reputation). ## Step 2: CEO Circle of Competence ### Strategic Foresight Use `web_search` to collect the CEO's public statements over the past 5 years (shareholder letters, calls, interviews, social media); extract their judgments: | Time | CEO's judgment/prediction | Actual outcome | Accuracy | |------|---------------------------|----------------|----------| | | "We believe market X will..." | X actually... | ✅/❌ | Key questions: Has the CEO made correct calls ahead of the market? Stayed calm when everyone was bullish? Is their industry understanding independent or following the crowd? ### Execution | Dimension | Assessment | Evidence | |-----------|-----------|----------| | Strategy-to-execution | Did they do what they said? | | | Organization | Can they attract and retain talent? | | | Crisis handling | How do they respond to difficulty? | | | Iteration speed | How fast do they correct mistakes? | | ## Step 3: Integrity Assessment (most important) > Buffett: "We look for three qualities: integrity, intelligence, and energy. Without the first, the other two will kill you." ### Promise-vs-Delivery Tracking Extract specific commitments from the past 3 years (calls, letters, interviews) via `get_sec_filings` / `web_search` / `get_stock_news`: | # | Time | Commitment | Occasion | Delivery | Rating | |---|------|-----------|----------|----------|--------| | 1 | | "X business profitable in 2025" | 2024 annual call | | ✅/⚠️/❌ | | Delivery rate | Rating | |:-------------:|--------| | >80% | Excellent — does what it says | | 60-80% | Acceptable — right direction, execution gaps | | 40-60% | Concerning — over-promises, under-delivers | | <40% | Serious problem — untrustworthy | ### Behavior in Hard Times Search for major crises (price crash, earnings miss, regulatory shock, competition); analyze management's response: proactive comms or hiding? Internal attribution or blaming external? Used the crisis to do the hard right thing or to pander short-term? ### Treatment of Stakeholders | Stakeholder | Attitude | Evidence | Rating | |-------------|----------|----------|--------| | Shareholders | Respect/ignore/exploit | | | | Employees | Treat well/exploit/ignore | | | | Customers/users | Customer-first/short-term extract | | | | Merchants/suppliers | Fair/extreme price pressure | | | | Regulator/society | Compliant/corner-cutting | | | ## Step 4: Capital Allocation Buffett's most-valued ability — **for every dollar earned, how much does management turn it into?** Search past 5 years of capital decisions (`web_search` / `get_financial_statements`); score each: **M&A record**: time / target / amount / strategic logic / after-the-fact return / score(1-5) **Buybacks** (use `financial_rigor` `command=verify_valuation` to check PE at buyback time vs now): time / amount / avg price / PE then / retrospective / score(1-5) **Dividends**: year / amount / payout ratio / vs FCF / sustainable **New business investment**: time / area / cumulative spend / status / return / score(1-5) ### Capital Allocation Score | Dimension | Score(1-5) | Notes | |-----------|:---------:|-------| | M&A discipline | | Right price? Integration? | | Buyback timing | | Buy low, stop high? | | Dividend rationality | | Payout vs FCF? | | New business | | Success rate? Stop-loss discipline? | | Cash management | | Reasonable reserves? Hoarding? | | **Overall** | | | ## Step 5: Governance ### Equity Structure | Item | Detail | Risk | |------|--------|------| | Dual-class / super-voting? | | | | Founder/controller stake? | | | | VIE structure? | | | | Independent directors truly independent? | | | | Recent major-holder changes? | | | ### Compensation | Executive | Total annual comp | % of net income | vs peers | Reasonable? | |-----------|-------------------|-----------------|----------|-------------| Is incentive aligned with long-term shareholders or encouraging short-term behavior? ### Related-Party Transactions | Related party | Transaction | Amount | Arm's length? | Risk | |---------------|------------|--------|---------------|------| ## Step 6: Side Validation AI can't meet face-to-face, but cross-check via public channels: - **Employee view**: `web_search` for Glassdoor ratings, discussions (mark platforms requiring login as "user can supplement") — culture, management rating, intensity, compensation, growth. - **Customer/merchant view**: App Store ratings, complaints, merchant forums. - **Industry reputation**: peer and insider views on this management. ## Step 7: Post-CEO Scenario > Buffett: "A great company should be one that a fool can run — because eventually one will." - If the CEO left tomorrow, would the company run normally? - How deep is the management team? A clear successor? - Is the competitive advantage dependent on the CEO personally or on organization/system? - Have past management transitions been smooth? ## Step 8: Output Structure: ① Key people overview; ② Integrity (delivery rate + hard times + stakeholders); ③ Ability (foresight + execution + capital allocation); ④ Governance; ⑤ Side validation; ⑥ Overall score and verdict. ### Overall Score | Dimension | Weight | Score(1-5) | Weighted | |-----------|:------:|:---------:|:--------:| | Integrity | 35% | | | | Strategy & execution | 25% | | | | Capital allocation | 25% | | | | Governance | 15% | | | | **Total** | 100% | | | ### Duan Yongping's 3 Questions 1. Is this person **honest**? (truthful, doesn't take advantage of shareholders) 2. Is this person **capable**? (strategic foresight + execution + capital allocation) 3. Would you hand this person your money for **10 years**? All three "yes" = ★★★★★; first two "yes" = ★★★★; only the first "yes" = ★★★; first is "no" = ★ (don't invest). ## Step 9: Save Use `write_file` to `reports/{company}-management-{YYYYMMDD}.md`. Then `report_audit` (`extract` → verify → `verdict`) as a quality gate on the numbers. ## Key Principles - **Integrity is a veto** — ability can be learned; character can't be fixed. - **Watch behavior, not words** — what they say doesn't matter; what they do does. - **Truth shows in hard times** — everyone's a good CEO in a tailwind. - **Capital allocation is the ultimate exam** — making money is easy; allocating it well is hard. - **Don't fall in love with management** — stay objective; even someone you admire can make big mistakes.
