Institutional portfolios don’t fall behind gradually. They fall behind in a few critical moments—and often never catch up.
Many endowments and foundations pursue similar investment strategies, with comparable allocations across public equity, private markets, real assets, and fixed income. Yet over time, their outcomes diverge in meaningful ways.
This research introduces the Dispersion Trap, a dynamic where underperformance during periods of wide return dispersion creates wealth gaps that become structurally difficult to close.
When dispersion is elevated, even small differences in performance can compound into permanent differences in institutional wealth. As dispersion compresses, the opportunity to recover narrows, making it harder for portfolios to catch up, even with stronger future returns.
The paper explores how these gaps form, why they persist, and what they reveal about how institutional portfolios are evaluated. It challenges the assumption that all underperformance is recoverable and highlights the importance of understanding when performance differences occur—not just how much.
