❓ 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.
⚠️ Common Pitfalls
Confusing a low price with true cheapness
Using one metric without business context
Overly optimistic assumptions that erase margin of safety
📚 Case Studies
1
Dot-Com Bubble Mean Reversion (2000)
Grantham warned that tech stocks were absurdly overvalued versus historical norms and trimmed GMO’s exposure before the crash.
✨ Outcome：When the bubble burst, GMO portfolios fell less than the market and later redeployed into cheaper equities as valuations normalized.
2
U.S. Housing and Credit Bubble (2007)
Grantham highlighted extreme overvaluation in U.S. housing and risk assets, cutting exposure to equities and credit pre-crisis.
✨ Outcome：GMO avoided the worst of the 2008 collapse and then added risk as spreads and equity valuations reverted toward historical averages.
