Investment Decision
The secret of success is not being right — it is avoiding big mistakes.
Compounding works for those who stay in the game long-term.
Analyst Exercise: Score 5 watchlist companies /25. Deep study those scoring 20+. Ask: "Would I remain an owner even if the market closed for 5 years?"
"Avoiding stupidity is easier than seeking brilliance." — Charlie Munger
Business (1–5): Understand it? Revenue model? Industry growing? Growth drivers? Circle of competence?
Moat (6–8): Economic Moat? Pricing Power? Market Share?
Financials (9–14): Sales/Profit growth? ROCE? Debt? FCF? Altman Z?
Management (15–18): Promoter holding? No pledge? Governance? Capital Allocation?
Valuation (19–21): Fair? MoS? Historical valuation?
Risk (22–24): Industry/Regulatory risk? Downside?
Portfolio (25): Position Size?
Example: ROCE 25%, low debt, positive FCF, strong moat — but P/E 90 → "Excellent business, valuation risk present" — balanced thinking.

Worked Example — Indian Market
Example 1 - Portfolio Split
Rs. 10L: 8 stocks at 7% each + ETF 20% + cash 9%. Max single stock 10%.
Example 2 - Sell Discipline
Thesis broken (ROE fall + debt rise) -> exit regardless of price.
Real World Example
Investor A: YouTube, P/E, News, Tips — inconsistent decisions. Investor B: Fixed checklist before every investment. Success comes from process, not intelligence. That is professional investing.
Case Study
Buffett's invisible checklist: Understand business? Moat? Trustworthy management? Fair valuation?
Checklist does not decide — it reduces mistakes.
Sell Checklist (often missing): Thesis broken? Valuation extreme? Management changed? Better opportunity?
