Readers praise its actionable framework, though critics note it requires discipline to avoid emotional decisions during market volatility.

What are the main investing principles in Rule #1?

Phil Town’s core principles include:

• Rule #1: Never lose money by overpaying for stocks.

A “wonderful business” has:

• Consistent revenue growth (≥10% annually).
• High profitability (ROIC ≥10%).
• Durable competitive advantages (e.g., Coca-Cola’s brand).
• Ethical management aligned with shareholder interests.

What is the “Margin of Safety” in Rule #1 investing?

The margin of safety is buying stocks at 50% below their calculated intrinsic value. This buffer protects against valuation errors or market downturns. For example, if a stock’s true value is $100, Rule #1 investors wait to purchase it at $50 or less.
