❓ 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
Ford Motor Turnaround (1974)
During the 1973–74 bear market, Ford traded at a very low P/E as auto demand slumped. Neff bought heavily, believing earnings would normalize when recession and oil-shock fears eased.
✨ Outcome：Within several years, Ford rebounded sharply, delivering substantial gains and validating the low P/E contrarian bet.
2
General Electric Revaluation (1982)
Early 1980s recession fears pushed GE’s P/E below market averages despite solid cash flows and strong business franchises. Neff accumulated shares, expecting profit growth to resume with economic recovery.
✨ Outcome：As earnings and confidence improved through the 1980s, GE’s stock and valuation rose, producing significant outperformance.
