❓ Why It Matters
Ignoring valuation turns even good companies into poor investments. Overpaying compresses future returns and leaves little margin when assumptions are wrong.
🎯 How to Practice
Estimate intrinsic value with conservative assumptions, set clear buy ranges, and act only when price offers a meaningful discount with acceptable downside.
⚠️ Common Pitfalls
Confusing a low price with true cheapness
Using one metric without business context
Overly optimistic assumptions that erase margin of safety
📚 Case Studies
1
Bernie Madoff’s Ponzi Scheme (2008)
Bernie Madoff, once a respected market maker and former NASDAQ chairman, ran a decades-long Ponzi scheme promising steady, above-market returns. Already wealthy and influential, he nonetheless kept expanding the fraud, taking in billions from individuals, charities, and institutions. When the 2008 crisis provoked mass redemption requests, the scheme collapsed because there were no real underlying investments.
✨ Outcome：Madoff received a 150-year prison sentence; many investors were financially ruined. His refusal to accept “enough” turned great success into catastrophic criminal failure, illustrating how greed can erase both fortune and legacy.

Launch of the First Index Mutual Fund (1976)
In 1976, Jack Bogle’s Vanguard introduced the First Index Investment Trust (later Vanguard 500 Index Fund), tracking the S&P 500. Wall Street ridiculed it as “Bogle’s folly,” since most investors preferred star stock pickers and high-fee active funds.
✨ Outcome：Over decades, the simple S&P 500 index beat the majority of active U.S. stock funds after costs. The fund’s success demonstrated that owning the whole market cheaply usually outperforms trying to pick the winning stocks or managers—the core of “buy the haystack.”
