Investment Principles Checklist

From Weekly I/O#122


Munger's Investment Checklist: Great investing follows principles in nine categories: Risk, Independence, Preparation, Rigor, Allocation, Patience, Decisiveness, Change, and Focus.

Book: Poor Charlie's Almanack (Stripe Press edition)

Checklists minimize errors. Munger organizes his investment principles into nine themes:

  1. Risk: Start by measuring risk, especially reputational. Avoid questionable characters. Shun permanent loss.

  2. Independence: Just because others agree or disagree doesn't make you right or wrong. Only the correctness of your analysis matters.

  3. Preparation: The only way to win is to work, work, work, and hope for a few insights. The will to prepare beats the will to win.

  4. Analytic Rigor: Determine value apart from price, progress apart from activity. Invert, always invert.

  5. Allocation: Your number one job. The best use is measured by the next best use. When odds favor you heavily, bet big.

  6. Patience: Resist the bias to act. Compound interest is the eighth wonder. Never interrupt it unnecessarily.

  7. Decisiveness: When circumstances are right, act with conviction. Opportunity meeting the prepared mind—that's the game.

  8. Change: Accept unremovable complexity. Challenge your best-loved ideas. Recognize reality, especially when you don't like it.

  9. Focus: Keep it simple. Reputation and integrity are your most valuable assets. Face your big troubles directly.

These apply beyond investing. They're a framework for any high-stakes decision.
