NBK Wealth Thought Leadership: The Power of Diversification in Private Markets
Background: The Age-Old Wisdom of Diversification
Long before the rise of complex financial theories and stock markets, people understood a fundamental principle about managing risk: Don’t Put All Your Eggs in One Basket. This idea is so intuitive that it appears in literature and everyday wisdom across cultures.
For instance, in William Shakespeare’s play The Merchant of Venice, written in the late 16th century, the character Antonio, a successful merchant, demonstrates this understanding. He declares, “My ventures are not in one bottom trusted, / Nor to one place... Therefore, my merchandise makes me not sad.” In simpler terms, Antonio says that he has spread his investment holdings across different ships and locations. He recognizes that diversifying his ventures makes him less vulnerable to any single misfortune, like a shipwreck or a trade route disruption.
This concept of spreading risk wasn’t limited to merchants. Farmers understood the importance of planting different crops, and rulers knew the value of having allies in various regions. The core idea is the same: diversification provides a safety net. It was a concept that was intuitively understood throughout time.
Introduction: Harry Markowitz and the Birth of Modern Portfolio Theory
Fast forward to the mid-20th century. The financial world was becoming increasingly complex, and investors needed a more sophisticated way to manage their portfolios. Enter Harry Markowitz, an economist who revolutionized the field of finance with his groundbreaking work in the 1950s.
Markowitz took that age-old wisdom of diversification and formalized it into what we now call Modern Portfolio Theory (MPT). He provided a mathematical framework for building well-diversified portfolios.
Diversification in investing is analogous to constructing a well-balanced meal. A balanced diet includes different food groups for good health. Similarly, a well-rounded investment portfolio includes different types of assets to manage risk and improve potential returns.
MPT applies a similar logic to investing. Instead of food groups, we have different asset classes like stocks, bonds, and real estate. Each asset class has its own risk and return characteristics, just like different foods have different nutritional values.
Markowitz’s key insight was as follows: The risk and return of an individual investment are less important than how that investment behaves in relation to other investments in the portfolio. Portfolio risk can be mitigated, without necessarily sacrificing potential returns, by combining assets with uncorrelated or negatively correlated performance. This principle, known as diversification, involves strategically blending assets that react differently to market fluctuations. This approach forms the cornerstone of Modern Portfolio Theory.
In short, MPT provides a framework for building diversified portfolios that aim to achieve the best possible return for a given level of risk. While the practical application of MPT can be complex, its core principles have had a profound and lasting impact on how we understand and manage investments. It transformed a timeless piece of wisdom into a cornerstone of modern finance.
Table 1. Private Market Performance (2010-2024) & 15-Year IRR(1)

Key Observations on Diversification Benefits from the Table
The Table shows the combined returns (Pooled IRR) for different types of private investments, grouped by the year the investment started (Vintage Year). This approach (Pool IRR by vintage) provides a basis for comparison of private market strategies and measurement of diversification benefits by showing performance across economic cycles.
Pooled IRR refers to the return of a single, large investment made up of many smaller, similar investments. It gives a realistic picture of what investors earned.
Vintage Year is simply the year an investment fund began. Funds that start in the same year are grouped because they face similar market conditions, making it fairer to compare them.
Private Capital Portfolio Performance Analysis: A Diversified Approach
This analysis examines the annualized returns of various private market investment strategies from 2010 to 2024, alongside their 15-year annualized returns (the “Horizon” column). Private market refers to investments in assets not traded on public exchanges, including strategies such as Buyouts (acquiring majority control of established companies, either private or public), Venture Capital (funding early-to-late-stage businesses), Direct Lending (providing capital to private companies), Real Estate, and Infrastructure.
The focal point of this analysis is the “Diversified Portfolio” row highlighted at the bottom of the table. This portfolio represents, in our hypothetical example, an equally weighted allocation across all listed private market strategies, providing a comprehensive view of private market performance as an asset class and mitigating the volatility inherent in individual strategies.
The Importance of Diversification: Mitigating Risk and Enhancing Stability
Observing the individual strategy returns shows significant year-on-year fluctuations. For instance, Venture Capital demonstrated substantial growth in 2020 and 2021, followed by a contraction in 2022. Similarly, Real Estate experienced periods of both appreciation and decline, notably in 2022 and 2023. This volatility is characteristic of sector-specific performance, influenced by prevailing economic conditions.
Conversely, the “Diversified Portfolio” exhibits a more consistent pattern of positive returns, albeit without the extreme highs or lows of individual strategies. This underscores the fundamental principle of diversification: by allocating capital across a spectrum of private market strategies, the impact of underperformance in any single area is minimized. The gains in one strategy can offset losses in another, resulting in a more balanced and stable overall return profile.
Long-Term Value Creation: The Power of Compounding
Generally, investment success is predicated on sustained growth over time, rather than short-term speculative gains. The “15-Year Horizon” column presents the annualized return for each strategy and the diversified portfolio. The diversified portfolio demonstrates a compelling 12.8% annualized return, competitive with individual strategies but achieved with reduced volatility.
This highlights the advantages of a long-term investment horizon in the private market. While individual years may present unpredictable fluctuations, a diversified approach seeks to generate consistent, robust returns over the long term, capitalizing on the illiquidity premium1 inherent in private markets.
Important Considerations
While the power of diversification is evident in its potential to smooth returns and mitigate risk, it’s equally important to remember that it doesn’t eliminate all risk. Past performance is not indicative of future results. Investors in private markets must also consider factors such as the inherent illiquidity (difficulty in buying and selling assets promptly) and the typically longer investment time horizons associated with this asset class.
These factors, while potentially contributing to the illiquidity premium and long-term return potential, require careful consideration and alignment, primarily, with individual investor liquidity needs, risk profile and investment objectives. A diversified approach, while offering significant advantages, should be viewed within the context of these important considerations.
Conclusion
The data for the diversified private market portfolio strongly supports the benefits of diversification. An equally weighted portfolio across various private asset strategies demonstrates the potential to achieve:
· More consistent positive returns: Performance is less reliant on any single strategy’s success, resulting in a smoother, more dependable return profile.
· Lower volatility: Diversification mitigates the impact of market fluctuations, promoting greater performance stability.
· Mitigation of downside risk: Losses in one area can be offset by gains in others, protecting the portfolio from substantial declines.
This analysis reinforces the advantages of a diversified approach to private capital investing, particularly for investors seeking consistent returns and effective volatility management.
