  Guy Spier's The Education of a Value Investor — an executable toolkit
  that applies value investing principles to both money and life: think
  independently, stay within your circle of competence, avoid cognitive
  biases, and cultivate the temperament for long-term success.

  Covers 5 use cases:
  ① Value Investing Mindset — adopt Graham and Buffett principles ("How to think like a value investor" "What is the Buffett approach")
  ② Circle of Competence — know what you know and stay within it ("How to know what I don't know" "Should I invest in industries I don't understand")
  ③ Cognitive Bias Awareness — recognize psychological traps ("Why do I make bad investment decisions" "How emotions affect stock picks")
  ④ Building a Network — surround yourself with smart people ("How to build a network of smart investors" "Who should I learn from")
  ⑤ Long-Term Thinking — develop patience for compounding ("How to think long-term" "How to stay disciplined when the market is crazy")

  Trigger when users say: "Guy Spier" "Education of a Value Investor" "Value investing" "Buffett"
  "Warren Buffett" "How to think about investing" "Circle of competence"
  "Investment psychology" "Long-term thinking" "Value investor"
  or mention: Guy Spier / The Education of a Value Investor / value investing /
  Warren Buffett / Benjamin Graham / circle of competence / temperament /
  cognitive biases / investing / stock market / long-term thinking /

## Philosophy — 5 rules to remember

1. **The most important investment is in yourself.** Knowledge and temperament compound over time.
2. **Know what you don't know.** Circle of competence is the most underrated concept.
3. **Temperament matters more than IQ.** Investing tests emotional control, not intelligence.
4. **Your network shapes your thinking.** Surround yourself with principled, smart people.
5. **Long-term thinking is a competitive advantage.** In a short-term world, patience is power.

## Intent Routing Table

| What the user is doing | Read this reference | Core tools |
|---|---|---|
| Learning value investing / "How to think like Buffett" | `references/1-core-framework.md` | Margin of safety, intrinsic value, Mr. Market |
| Defining competence / "What do I really know" | `references/2-principles.md` | Circle of competence, honesty with self |
| Recognizing biases / "Why do I make bad decisions" | `references/3-techniques.md` | Cognitive bias checklist, decision journal |
| Building network / "How to meet smart investors" | `references/5-voice-and-app.md` | Networking strategies, learning from mentors |
| Developing temperament / "How to stay calm" | `references/4-anti-patterns.md` | Anti-patterns — impatience, greed, fear |

## Core Framework Quick Reference

- **Value Investing** = Buy assets below intrinsic value. Gap between price and value is the margin of safety.
- **Circle of Competence** = Areas you truly understand. Stay within it. Outside is gambling.
- **Margin of Safety** = Buy at significant discount to intrinsic value. Protects from error.
- **Intrinsic Value** = Actual business worth, independent of stock price.
- **Mr. Market** = The market is a moody partner. Ignore or exploit his moods. Don't follow them.
- **Compounding** = Small consistent returns multiplied over time produce extraordinary results.

## Key Principles

1. **Invest in what you understand.** If you can't explain a business in one paragraph, you don't understand it.
2. **The market is not always right.** Price and value are different. Mr. Market's moods create opportunity.
3. **Your circle of competence can expand — but only through genuine learning.** Don't pretend to know what you don't.
4. **Your network is your net worth — but in quality, not quantity.** A few good mentors are worth more than a thousand acquaintances.
5. **Read constantly.** Buffett reads 500+ pages a day. Knowledge compounds like money.
6. **Keep a decision journal.** Write down why you make each investment. Review it later. Learn from your mistakes.
7. **Be patient.** The biggest returns come from holding good investments for decades, not days.

## Anti-Pattern Summary

The book's core correction: Most investors fail not because they're not smart enough but because they lack the right temperament. They chase hot stocks, trade too frequently, and let emotions drive decisions. The fix is value investing principles applied with patience and self-awareness. See `references/4-anti-patterns.md`.

### Invocation Test

Test with: *"I've been investing for five years. I've done okay, but I keep making the same mistakes: buying hot stocks that I don't really understand, selling in a panic when they drop, and then watching them recover without me. How do I break this cycle?"*

Expected output: Your problem is not lack of intelligence — it's lack of process. Spier's solution: 1) Define your circle of competence. Write down the 3-5 industries you truly understand. Only invest in those. 2) Create a decision journal. Before each trade, write down exactly why you're buying, what you think the business is worth, and when you'd sell. 3) Read about Mr. Market — the market's fluctuations are your opportunity, not your signal. 4) Find a mentor or peer group of principled investors. Spier credits his transformation to meeting Mohnish Pabrai and being part of a value investing network. 5) Read more. Start with Buffett's letters and Benjamin Graham. Knowledge creates confidence. Confidence creates patience. + Watermark.
