❓ 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
Warren Buffett’s Concentrated Bet on Berkshire Hathaway (1964)
In the early 1960s, Warren Buffett ran a highly concentrated partnership portfolio, with his largest position becoming the struggling textile firm Berkshire Hathaway. In 1964, after accumulating a large stake through tender offers and open-market purchases, Buffett effectively took control of Berkshire, despite its narrow business and operational headwinds.
✨ Outcome：Although the textile business itself was mediocre, owning a large, focused controlling stake let Buffett repurpose Berkshire as an investment holding company. This single, highly concentrated bet became the platform for an extraordinary compounding machine. The lesson: a few dominant positions, deeply understood and actively controlled, can shape an investor’s long-term results more than dozens of smaller trades.

Bill Ackman’s Concentrated Long in Canadian Pacific Railway (2013)
In 2011–2012, Pershing Square built a large, concentrated activist stake in Canadian Pacific Railway, ultimately around 14% of the company, making it one of the fund’s largest positions. In 2012, Ackman led a proxy fight, replaced much of the board, and installed rail veteran Hunter Harrison as CEO. By 2013, operational changes and efficiency improvements were translating into higher profitability.
✨ Outcome：Between Ackman’s entry in 2011 and his exit beginning in 2016, CP’s stock price rose several-fold, generating billions in gains for Pershing Square from one core position. The episode shows how deep research, active engagement, and conviction in a single large stake can produce outsized returns, validating the strategy of making a few large, focused bets instead of many small, diffuse ones.
