Long-Term Horizon
Endowments have perpetual horizons; accept illiquidity for higher expected returns.
Endowments have perpetual time horizons. This allows us to accept illiquidity and short-term volatility in exchange for higher long-term returns. Think in decades, not quarters.
🏠 Everyday Analogy
📖 Core Interpretation
Patience and a long horizon are competitive advantages in investing
💎 Key Insight：Unlike individuals saving for retirement, endowments fund universities in perpetuity and can tolerate decades of illiquidity. This allows them to invest in private equity, venture capital, and real assets that lock up capital for 7-10 years but offer illiquidity premiums. Individual investors with shorter horizons and liquidity needs should not replicate this approach without caution.

Staying the Course in the Global Financial Crisis (2008)
Equities, REITs, and commodities plunged over 40% while Treasuries and high‑quality bonds rallied, severely testing diversified portfolios.
