Analysis based on the Common Stocks and Uncommon Profits skill. For educational use only.

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

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
