Key Takeaways
- • The performance gap between top and bottom endowments and foundations more than doubled in 2025, with dispersion exceeding 10 percent annually, compared to a historical norm of roughly 4 percent in 2024.
- • Three-year performance dispersion among OCIO-managed endowment portfolios has doubled to approximately 8 percent annually, compounding to over 25 percent cumulative performance divergence across the three-year period.
- • Portfolio construction differences—rather than asset allocation similarities—are driving the widening performance wedge, with variations in equity exposure, venture capital allocations, private equity vintage timing, and liquidity policies creating materially different outcomes.
- • OCIO Analytics identifies five primary drivers of dispersion: concentrated equity leadership, lagging private market valuations, venture capital cycle resets, private equity vintage performance variance, and divergent liquidity management approaches.
- • Brad Alford, founder of OCIO Analytics, emphasizes that while endowments maintain comparable high-level allocations (typically 80 percent growth assets, 20 percent risk-mitigating assets), the underlying implementation composition is what determines performance outcomes.
Summary
The divergence in endowment and foundation performance has reached historically elevated levels in 2025, with OCIO Analytics data revealing a more than doubling of the performance gap between top and bottom performers—exceeding 10 percent annually despite broad equity market strength. Over a three-year horizon, this dispersion effect becomes more pronounced, with the performance spread doubling from the historical 4 percent annual average in 2024 to approximately 8 percent annually in 2025, translating to cumulative divergence exceeding 25 percent when compounded across the three-year period.
Contrary to conventional wisdom, the source of this performance wedge is not asset allocation decisions at the strategic level but rather implementation choices at the tactical and operational level. According to OCIO Analytics' white paper analysis, while most institutional portfolios maintain superficially similar allocations—emphasizing growth assets and private markets in comparable proportions—the composition and execution of those allocations varies significantly. The research identifies five specific drivers of performance dispersion: concentrated equity exposure decisions by leading performers, valuation lags in private market holdings, venture capital cycle dynamics and resets, private equity vintage timing considerations, and differing approaches to portfolio liquidity management.
Brad Alford, founder of OCIO Analytics, underscores that the endowment model's apparent simplicity masks considerable underlying complexity. He notes that while most endowments construct portfolios with roughly 80 percent allocated to growth assets and 20 percent to risk-mitigating assets, "the composition of these portfolios is what's different, and it really shows up in these trailing three years." The white paper concludes that implementation choices in equity exposure levels, venture capital allocations, private equity vintage selection timing, and liquidity policies generate materially divergent outcomes when specific market conditions emerge—conditions that characterized 2025's investment environment.
This performance dispersion exposes fundamental structural differences in how institutions with ostensibly aligned investment philosophies execute their mandates. The data suggests that the endowment model's conventional framework obscures significant variation in actual portfolio construction, with superior performance increasingly dependent on granular tactical decisions rather than top-line strategic asset allocation alone.
