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

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