Visual Guide
Worked Example — Indian Market
Example 1 - Journal Entry
Stock | Date | Thesis | Buy Price | Invalidation trigger | Review date.
Example 2 - Philosophy Line
One sentence filter: what you buy, at what price, for how long.
Real World Example
Investor A: Intelligent — no rules, no process, FOMO buy, Panic sell.
Investor B: Average IQ — clear rules, checklist, risk management, journal.
20 years later: Investor B wins — Systems → Process → Results.
Case Study
Buffett: System built + 60+ years discipline = compounding secret.Indian investor: Apply same framework to Asian Paints (quality hold), TCS (thesis journal), sector limits prevent over-concentration in IT.
