📖Joel Greenblatt
Focus on Earnings Yield
Earnings yield is superior to P/E ratio.
Earnings yield (EBIT/Enterprise Value) is a better measure of cheapness than P/E ratio.
🏠 Everyday Analogy
📖 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.

❓ Why It Matters
Ignoring valuation turns even good companies into poor investments. Overpaying compresses future returns and leaves little margin when assumptions are wrong.
🎯 How to Practice
Estimate intrinsic value with conservative assumptions, set clear buy ranges, and act only when price offers a meaningful discount with acceptable downside.
🎙️ Master's Voice
If you wait for the perfect time to invest, you will wait forever.
Greenblatt encourages action. Waiting for perfection means missing opportunities. Good enough is good enough.
