❓ 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

Yale’s Early Private Equity Push (2000)

✨ Outcome:Despite the dot‑com crash, Yale’s private equity portfolio delivered strong long‑term returns, validating alternative allocations.
2
Endowment Through the Global Financial Crisis (2008)
The Yale model, heavy in illiquid alternatives like private equity, real assets, and hedge funds, faced severe short‑term stress as markets and liquidity conditions collapsed.
✨ Outcome:Although the endowment declined sharply in 2009, alternatives recovered strongly over subsequent years, outperforming traditional 60/40 portfolios.
