❓ Why It Matters
Without portfolio rules, decisions become reactive and concentrated. Sustainable returns come from controllable risk exposure, not one-off bets.
🎯 How to Practice
Set target allocation by risk tolerance, rebalance by rules rather than headlines, and prevent hidden concentration from dominating portfolio behavior.
⚠️ Common Pitfalls
Diversifying superficially without true risk balance
Skipping rebalancing rules and drifting style
Judging portfolio health by short-term returns only
📚 Case Studies
1
Eastern European Distressed Debt (1990)
Following the fall of the Iron Curtain, Baupost bought distressed and defaulted sovereign bank debt of Eastern European countries at deep discounts.
✨ Outcome：As countries restructured and normalized relations, debt prices rose substantially, producing attractive, low‑correlated gains over several years.
2
Post-Crash Value Screening (1987)
After the 1987 crash, Klarman’s team performed bottom-up analysis on dozens of bombed-out equities, focusing on balance sheets, asset coverage, and downside protection rather than macro forecasts.
✨ Outcome：Accumulated deeply discounted securities; several doubled or more over the next few years as valuations normalized.
