❓ 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
Buffett’s Enduring Bet on Coca‑Cola (2005)
Warren Buffett began buying Coca‑Cola in 1988 after its 1987 crash, attracted by its global brand, distribution network, and scale. By 2005, Coke had faced currency headwinds, health concerns over sugary drinks, and new competitors, yet its market share and pricing power remained resilient.
✨ Outcome：Berkshire’s stake, bought for about $1.3B, produced several times that in dividends alone and became worth tens of billions. The case shows how a powerful brand and distribution moat can sustain value creation over decades despite shifting consumer trends.
2
Visa and Mastercard’s Network Effects (2012)
Since their IPOs (Visa 2008, Mastercard 2006), both firms leveraged vast merchant acceptance, trusted brands, and bank partnerships. By 2012, despite regulatory pressures on interchange fees and new payment technologies, they continued to grow volumes as global commerce digitized.
✨ Outcome：Long‑term shareholders enjoyed enormous compound returns as profits scaled with transaction volume. The case illustrates how two‑sided network effects and global infrastructure can form a durable moat that persists through technology shifts and regulatory changes.
