Big idea

The secret isn’t “good assets” — it’s good prices

Most people try to buy the “best companies.” Pros focus on the gap between price and intrinsic value. If you pay too much for greatness, you lose. If you pay too little for average-but-surviving, you win.

Howard Marks: “You don’t make money by buying good things. You make money by buying things for less than they’re worth.”

Why process beats outcomes (in the short run)

  • Randomness is real: Good decisions can lose; bad decisions can win—temporarily.
  • Your edge is repeatable thinking: Define how you estimate value, size positions, and control risk.
  • Survival > bravado: Compounding works only if you stay solvent.

The Loser’s Game: win by avoiding mistakes

In amateur tennis, you win by keeping the ball in play. In investing, you win by avoiding unforced errors: overpaying, overleverage, overconfidence.

  • Don’t overpay: A great business at the wrong price is a bad investment.
  • Control downside: Position sizing, diversification, covenant awareness, cash buffers.
  • Beware extrapolation: What “should” happen often doesn’t—especially on schedule.
  • No hero trades: If one outcome ruins you, don’t take the bet.

Price vs. Value: a simple mental model

When you win

Buy ≤ Intrinsic Value

  • Unpopular, misunderstood, or cyclical assets.
  • Low expectations → upside surprises.
  • Patience lets value surface.

When you lose

Pay >> Intrinsic Value

  • “Quality at any price” mania.
  • FOMO replaces analysis.
  • Reversion hurts the late buyers.

Decision framework (keep it on your desk)

StepQuestionAction
1. ValueWhat is a sober estimate of intrinsic value?Use conservative assumptions; range-of-outcomes, not a point.
2. PriceHow wide is the discount (margin of safety)?Demand a cushion for error, time, and randomness.
3. DownsideWhat can permanently impair capital?Stress test: leverage, liquidity, cyclicality, governance.
4. CatalystsAny forces that close the gap?Optional: maturities, buybacks, breakups, activists—nice-to-have, not required.
5. SizingHow wrong can I be and still survive?Right-size positions; diversify sources of risk.
6. PatienceCan I hold through discomfort?Write the thesis; pre-commit to hold/exit rules.
Marks’ three adages (worth memorizing)
  • “What the wise man does in the beginning, the fool does in the end.” Be early or be selective.
  • “Never forget the six-foot man who drowned in a five-foot river on average.” Survive the bad days.
  • “Being too far ahead of your time is indistinguishable from being wrong.” Stay power matters.
