Unlocking Endowment Performance: A Modern Strategy for Today’s Markets

Managing institutional capital has always required a delicate balance. Nonprofits and higher‑education endowments must fund today’s operations while also protecting the purchasing power of their assets for future generations. This idea of “intergenerational equity” is simple to articulate but difficult to execute, especially in a world where markets move faster and more unpredictably than ever.

For decades, the Yale Model was the gold standard for endowment management. Its emphasis on long‑term thinking, diversification, and the heavy use of private-market investments shaped the playbook for institutions across the country. But the markets back in the 1980s and 1990s are not the same as today’s. Recent years have revealed significant cracks in the traditional approach, prompting many boards to rethink whether the old model still serves their mission.

At Armbruster Capital Management, we share the Yale Model’s long‑term mindset, but we take a very different path to get there. Our approach is grounded in transparent, liquid, evidence‑based strategies that align with the realities of today’s markets. 

The Yale Model: A Breakthrough Built on Traditional Alternatives

When David Swensen introduced the endowment model at Yale, it reshaped institutional investing. Instead of relying on a traditional 60/40 stock‑bond mix, he leaned heavily into private equity, venture capital, and hedge funds. The idea was simple but powerful: because endowments have long time horizons, they can accept illiquidity in exchange for higher expected returns.

For decades, this approach worked. Private markets were smaller, less crowded, and full of inefficiencies that skilled managers could exploit. Endowments with the largest allocations to these alternatives often posted the strongest results.

But the world has changed. Private‑equity fund sizes have ballooned, competition has intensified, and the alpha that once justified these allocations has become harder to find. The very characteristics that once made traditional alternatives so attractive—illiquidity, opacity, long lockups—have become liabilities in a market environment that demands flexibility and transparency. Findings from the 2024 NACUBO‑Commonfund Study of Endowments (NCSE), the industry’s most comprehensive annual review of endowment performance and asset allocation, clearly reflect this shift, showing that the model’s historical advantages have narrowed considerably.

The Cracks Are Now Visible

The last few fiscal years have highlighted just how much the landscape has changed. Historically, the largest endowments with the biggest allocations to private markets have delivered the strongest results. But in 2023 and 2024, the opposite happened.

Smaller endowments with simpler, more public‑equity‑heavy portfolios outperformed their larger peers by a wide margin. In 2023, endowments over $5 billion returned just 2.8%, while those under $50 million returned 9.8%. The difference wasn’t manager skill—it was asset allocation. Smaller institutions, unable to build sprawling private portfolios, were overweight U.S. stocks at a time when mega‑cap technology companies (like the Magnificent 7) were driving the market higher.

Meanwhile, private market valuations did not keep pace with the public market rally. Many institutions found themselves short on liquidity just as public markets were taking off. The traditional model’s reliance on the “art” of manager selection—opaque, expensive, and slow‑moving—left them flat‑footed.

These challenges don’t mean the Yale Model is broken. But they do suggest that the world it was built for no longer exists.

A Modern Alternative: Armbruster’s Evidence-Based Approach

At Armbruster Capital Management, we believe in alternatives, but not the traditional kind. Instead of locking capital into illiquid private funds, we use liquid alternatives that provide true diversification and daily transparency. These strategies form a “third leg of the stool” alongside stocks and bonds, offering returns that differ from traditional markets.

Yale Model’s Traditional Alternative Strategy	Armbruster’s Liquid Alternative Strategy
Private equity, venture capital, hedge funds	Daily/Quarterly liquidity
Illiquid for 7–12 years	Transparent mutual and interval funds
Opaque valuations	Data-driven strategies
Dependent on manager skill	Low correlation to stocks and bonds
Slow to respond to market changes	No dependence on IPO markets or fundraising cycles

Our alternative allocations focus on risks that have nothing to do with the stock market:

• Catastrophe Bonds: These pay attractive premiums for taking on insurance‑related risks. Their returns are driven by natural events rather than economic cycles, making them one of the purest diversifiers available.
• Managed Futures: Trend‑following strategies that can profit in both rising and falling markets. In years like 2008, they provided meaningful gains when most other asset classes were collapsing.
• Alternative Lending: Short‑duration loans to high‑quality borrowers that generate steady income without relying on equity market performance.
• Style Premia: Systematic long/short strategies that capture well‑documented factor returns, such as value versus growth, without taking broad market exposure.
• Multi-Strategy: Combines multiple asset classes and tactics within a single portfolio to diversify risk and pursue consistent returns across market environments.

Together, these tools offer equity‑like returns with bond‑like risk without the liquidity traps that plague traditional alternative investments.

A Steady Hand for Institutional Missions

The challenges facing endowments today, including higher costs, political scrutiny, liquidity demands, and the possibility of extended periods of muted returns, require a more modern playbook. The traditional endowment model remains influential, but its reliance on illiquid private investments has become increasingly difficult to reconcile with today’s market realities.

Armbruster Capital represents the next step in that evolution. We help institutions build portfolios that preserve the long‑term spirit of the endowment model, manage liquidity needs, and stay disciplined during periods of market stress. By replacing the “art” of the legacy Yale Model with transparent, evidence‑based “science,” we help institutions break the cycle of underperformance and better align their portfolios with their long‑term missions.

For organizations committed to protecting their financial future, now is the time to embrace a more modern, more resilient fiduciary strategy—one built for today’s markets, not those of 40 years ago.
