❓ Why It Matters
Without process, there is no reliable feedback loop. Structured execution and review improve decision quality over time.
🎯 How to Practice
Run a decision loop of research, thesis, execution, and post-mortem; document assumptions and update playbooks with evidence, not hindsight bias.
⚠️ Common Pitfalls
Having opinions without execution criteria
Reviewing outcomes but not decisions
Abandoning rules during volatility spikes
📚 Case Studies
1
Dot-Com Bubble Warning (2000)
Grantham publicly warned in 1998–2000 that tech stocks were in a massive bubble, reducing GMO client exposure to overvalued growth and internet shares.
✨ Outcome：Clients underperformed during the final surge, but avoided most of the 2000–2002 crash and preserved substantial capital.
2
Housing and Credit Bubble Call (2007)
Grantham labeled 2005–2007 a global housing and credit bubble, slashing exposure to risky mortgage-linked and leveraged financial assets before the crisis hit.
✨ Outcome：Underperformance before mid-2007, then strong relative results during the 2008 crash as portfolios were less exposed to collapsing financials.
