📖Joel Greenblatt

Focus on Earnings Yield

🌿 Intermediate★★★★★

Earnings yield is superior to P/E ratio. Ignoring valuation turns even good companies into poor investments. Overpaying compresses future returns and leaves little margin when assumptions are wrong. Estimate intrinsic value with conservative assumptions, set clear buy ranges, and act only when price offers a meaningful discount with acceptable downside. In Focus on Earnings Yield, Joel Greenblatt focuses on the gap between price and value. Returns come from paying less than what a business is worth, not from guessing short-term market moves. Key insight: Earnings yield (EBIT/EV) accounts for debt and is comparable across capital structures. Start with a minimal checklist: Am I waiting for perfection?; Is this good enough?; Am I missing opportunities?.

  • Am I waiting for perfection?
  • Is this good enough?
  • Am I missing opportunities?
  • Act on good opportunities

Avoid misuse: Confusing a low price with true cheapness

💬

Earnings yield (EBIT/Enterprise Value) is a better measure of cheapness than P/E ratio.

🏠 Everyday Analogy

Valuation is like buying a house: the asking price reflects mood, but true value comes from structure, location, and long-term utility. Good assets still need sensible prices.

📖 Core Interpretation

In Focus on Earnings Yield, Joel Greenblatt focuses on the gap between price and value. Returns come from paying less than what a business is worth, not from guessing short-term market moves.
💎 Key Insight：Earnings yield (EBIT/EV) accounts for debt and is comparable across capital structures. P/E ignores leverage and distorts comparisons. A company with $100M equity earning $10M looks cheap (10x P/E), but if it has $200M debt, enterprise value is $300M—much less attractive. Earnings yield provides an apples-to-apples measure of cheapness.
