Avoid Ruin Principle

The "Avoid Ruin" principle is a risk management approach that emphasizes preserving capital and staying in the game over taking extreme risks, even when conviction is high.

Core concept of "Avoid Ruin"

• Based on Kelly Criteria - prioritize not risking ruin and staying in the game
• Focus on avoiding disastrously risky financial investments
• Maintain health and avoid extremely dangerous activities
• Recognize that life can be great without taking existential risks

Different risk philosophies in investing and entrepreneurship

• Warren Buffett's approach:

  • "Don't risk what you have for what you don't need"
  • Has been concentrated (e.g., 50% portfolio in Apple) but not risking ruin
  • Focuses on concentration without existential risk

• Contrasting approaches:

  • The "1% of the 1%" (like Elon Musk) sometimes don't avoid ruin
  • Some extremely successful people take massive risks
  • Shaan believes these people are "great achievers but not necessarily wise"

Risk tolerance differences in different domains

• Value investing vs. tech investing:

  • Buffett predicts the future will repeat itself
  • VC/tech investing assumes the opposite - betting on disruption
  • "In our business, cynics get to be right and optimists get to be rich"
  • Both approaches valid in their respective domains

• Market sizing perspective:

  • Traditional market sizing often underestimates disruptive potential
  • "Sizing the market for a disruptor based on the incumbent's market is like sizing the car industry based on how many horses there were in 1910"

Balancing conviction with risk management

• Having conviction doesn't mean borrowing every dollar possible
• Even when believing in an investment thesis (like Bitcoin as "digital Manhattan")
• Courage to act on conviction is different from risking everything
• For successful people, "ruin" might be reputational rather than financial
