❓ Why It Matters
A single large drawdown can erase years of progress. Risk control is not timidity; it is the operating system that keeps compounding alive.
🎯 How to Practice
Define downside scenarios before entry, cap position size, avoid fragile leverage, and maintain liquidity so mistakes remain survivable.
⚠️ Common Pitfalls
Equating volatility with all forms of risk
Oversized positions without an exit plan
Using leverage to compensate for uncertainty
📚 Case Studies
1
Warren Buffett and the Long-Term Capital Management Crisis (1998)
When LTCM’s highly leveraged bets blew up in 1998, many investors clung to models that said such losses were nearly impossible. Buffett instead focused on the harsh reality of LTCM’s balance sheet and counterparties, analyzing its positions and the true risks rather than the elegant theories behind them.
✨ Outcome：Buffett declined to overpay for a bailout stake and preserved Berkshire’s capital. Lesson: discard comforting models when they conflict with observable reality; act on what is, not what “should” be.
2
Ray Dalio and Bridgewater Before the Global Financial Crisis (2008)
In the mid‑2000s, Dalio’s team rigorously examined credit data, debt growth, and lending standards. Their models and firsthand conversations showed an unsustainable debt bubble, even as consensus believed housing was safe. Bridgewater embraced this uncomfortable reality instead of following the optimistic narrative.
✨ Outcome：Bridgewater positioned defensively and profited during the 2008 crisis. Lesson: facing unwelcome facts early, and updating beliefs from evidence, is the foundation for resilient investment decisions.
