| 39 | ## Skill Purpose |
| 40 | |
| 41 | Help investors use Philip Fisher's growth stock method to systematically evaluate whether a company is worth holding long-term. Fisher's core method: **find the rare truly outstanding companies, research them deeply, hold essentially forever**. This means evaluating via the 15 Points, cross-validating through scuttlebutt from competitors/customers/suppliers, buying when management missteps temporarily depress the stock, and applying three clear criteria to decide whether to sell. |
| 42 | |
| 43 | This is not a trading tool or valuation calculator. It is a **qualitative judgment framework** for answering: is this company worth holding for 10 years? |

| 47 | ## Routing Rules |
| 48 | |
| 49 | | User question type | Must execute | Optional | |
| 50 | |---|---|---| |
| 51 | | Comprehensive company evaluation | M1 → M2 → M3 | M4 (is now the right time?) | |
| 52 | | Product/market/competitive analysis only | M1 | M2 | |
| 53 | | Management quality only | M2 | M1 | |
| 54 | | How to research a company / competitive intelligence | M3 | M1 | |
| 55 | | Is now the right time to buy? | M4 | M1 (confirm company qualifies) | |
| 56 | | Should I sell my position? | M5 | — | |
| 57 | | Is this stock overvalued? | M5 (hold logic) + M4 (P/E misconceptions) | — | |
| 58 | | Fisher philosophy / growth vs value | M1 + M5 | — | |

| 67 | - **M2 (Management)**: Read `subskills/m2_management/module.md`, case library: `subskills/m2_management/references/case_library.md` |
| 68 | - **M3 (Scuttlebutt)**: Read `subskills/m3_scuttlebutt/module.md`, case library: `subskills/m3_scuttlebutt/references/case_library.md` |
| 69 | - **M4 (When to buy)**: Read `subskills/m4_when_to_buy/module.md`, case library: `subskills/m4_when_to_buy/references/case_library.md` |

| 74 | ## What Not to Do |
| 75 | |
| 76 | - ❌ Never evaluate a company using only P/E, P/B, or other valuation ratios |
| 77 | - ❌ Never recommend selling because the stock has risen significantly |
| 78 | - ❌ Never recommend selling because of general market pessimism |
| 79 | - ❌ Never discuss buy timing (M4) without first establishing whether the company qualifies (M1) |
| 80 | - ❌ Never ignore Point 15 (integrity) — any integrity concern overrides all other positive scores |
