Introduction

The second path is faster, cheaper, and more effective. That is why great investors study history.
This chapter examines the great investors who built extraordinary wealth over decades.
Core Concepts
Financial Terms

Investor's Creed:
- I will think independently
- I will understand risk

- Decisions from process, not emotion

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
Priya, age 28, a new investor. She heard Buffett quotes on YouTube and immediately bought "value stocks" — without understanding that Buffett evolved his strategy over decades.
When the market fell 20%, she panic-sold. Her friend Amit applied Lynch's "Invest in what you know" — understanding the business models of his FMCG employer ITC and HUL before taking long-term positions, and using Graham/Marks risk-first thinking to control position size.
Five years later: Priya learned from copy-trading; Amit compounded through mental models + discipline.
The goal is not to copy great investors — it is to learn how they think.
Case Study
Warren Buffett — Coca-Cola (1988): Buffett identified Brand × Distribution × Global Scale. Decades-long holding demonstrated compounding — wonderful business + time.
Peter Lynch — Dunkin' Donuts / Taco Bell era: Lynch sourced investment ideas from everyday products, but always verified financials — product like ≠ investment thesis.
Indian context: TCS and HDFC Bank are "quality compounder" case studies for Indian investors — strong moat, capital allocation, and long-term holding mindset align with Buffett's philosophy.
CFA Exam Tip
A senior CFA analyst treats great investors as process libraries:
| Investor | Core Lesson | Application |
|---|---|---|
| Buffett | Quality + Time | Wonderful businesses at fair price |
| Lynch | Invest in What You Know | Start with circle of competence |
| Munger | Avoid Stupidity | Invert — "How can I lose money?" |
| Marks | Risk First | Prepare, don't predict |
| Graham | Margin of Safety | Mr. Market is servant, not master |
| Fisher | Great Businesses | Scuttlebutt + management quality |
| Templeton | Contrarian | Buy pessimism when fundamentals strong |
Common thread: Patience, Discipline, Independent Thinking, Risk Management — strategies differ, principles are the same.
Common Mistakes

- Treating Lynch-style "I use the product" as a full thesis
- Going contrarian like Templeton while ignoring weak fundamentals
- Overpaying for great names using Buffett's quality mantra
- Reading Munger mental models while ignoring position sizing / risk
- Completing a reading list but skipping journal + discipline
Key Takeaways
- Learning from others' mistakes and successes is the faster path
- Buffett: quality compounders + time; Lynch: know + verify; Munger: avoid stupidity
- Marks: second-level thinking; Graham: margin of safety; Templeton: contrarian with fundamentals
- Master formula: Knowledge + Patience + Discipline + Time
- Great investors are not born — read, think, err, learn, stay disciplined for decades
- The right question is not "Which stock?" — but "What can I learn from great investors?"
"In the short run, the market is a voting machine; in the long run, it is a weighing machine." — Benjamin Graham
