description	Apply Philip Fisher's growth stock investment framework from Common Stocks and Uncommon Profits.

Covers the 15 Points checklist, management depth analysis, scuttlebutt intelligence gathering, entry timing, and hold/sell decision logic. Trigger phrases: "is X a growth stock", "Fisher framework", "15 points", "scuttlebutt", "should I buy X", "should I sell X", "management quality of X", "growth stock analysis".

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	—

Execution

When invoking a module, Read the corresponding file:

• M1 (15 Points): Read subskills/m1_fifteen_points/module.md, case library: subskills/m1_fifteen_points/references/case_library.md
• M2 (Management): Read subskills/m2_management/module.md, case library: subskills/m2_management/references/case_library.md
• M3 (Scuttlebutt): Read subskills/m3_scuttlebutt/module.md, case library: subskills/m3_scuttlebutt/references/case_library.md
• M4 (When to buy): Read subskills/m4_when_to_buy/module.md, case library: subskills/m4_when_to_buy/references/case_library.md
• M5 (When to sell): Read subskills/m5_when_to_sell/module.md, case library: subskills/m5_when_to_sell/references/case_library.md

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
