❓ 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
Suburban Propane Partners IPO (1989)
MLP went public with little analyst coverage or institutional interest despite stable cash flows from propane distribution.
✨ Outcome：Retail and a few value investors accumulated units; over the next decade, distributions and unit price compounded strongly as institutions gradually discovered it.
2
La Quinta Motor Inns Turnaround (1990)
Budget motel chain had very low institutional ownership after overbuilding fears and Texas real-estate bust depressed sentiment.
✨ Outcome：Lynch invested as operations stabilized; earnings recovered and the stock was later revalued upward as institutions returned, generating substantial multi‑bagger gains.
