❓ Why It Matters
Without business-quality filters, investors drift toward stories rather than economics. Durable cash generation is what supports long-term valuation.
🎯 How to Practice
Use a checklist covering moat, management, unit economics, and capital allocation; track long-term cash generation instead of quarter-to-quarter noise.
⚠️ Common Pitfalls
Buying narratives instead of cash-generating economics
Overreacting to short-term operating noise
Ignoring management quality and capital allocation
📚 Case Studies
1
Procter & Gamble vs. Bankers Trust Derivatives Scandal (1994)
In the early 1990s, Bankers Trust sold complex derivatives to Procter & Gamble. Internal Bankers Trust recordings later revealed employees joking about how little P&G understood the risks. These tapes, initially hidden, came out in litigation after P&G suffered large losses, exposing a culture of opacity and manipulation.
✨ Outcome：The scandal damaged both firms, led to large settlements, and Bankers Trust’s eventual sale. It became a classic warning: hiding true risks and intentions erodes trust, drains energy in legal battles, and ultimately destroys long‑term business value.
2
Enron’s Off–Balance-Sheet Deception (2001)
Enron used opaque special purpose entities to hide debt and inflate earnings. Management, auditors, and some bankers knew of the structures but kept details from investors, employees, and even many directors. For years, enormous effort went into maintaining the illusion of strong profits and low leverage.
✨ Outcome：Enron collapsed into bankruptcy, wiping out shareholders and employee pensions and sending executives to prison. The scandal spurred Sarbanes–Oxley reforms. The case shows that secrecy consumes resources, destroys internal culture, and ultimately harms everyone when reality finally surfaces.
