❓ Why It Matters

Short-term noise often forces investors out before value is realized. Long-term discipline increases the odds that fundamentals, not emotions, drive outcomes.

🎯 How to Practice

Extend research and review horizon, reduce unnecessary turnover, and adjust only when intrinsic value, risk, or opportunity cost materially changes.

⚠️ Common Pitfalls

Calling it long term while never reviewing thesis
Overtrading and damaging compounding
Ignoring opportunity cost and alternatives

📚 Case Studies

1
Yale’s Early Private Equity Push (2000)
Following Swensen’s allocation philosophy, Yale expanded into venture capital and private equity during the tech bubble era, emphasizing manager selection and long-term horizons over market timing.
✨ 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.
