Introduction

In episode E161 of "How I Invest with David Weisburd," host David Weisburd engages in an insightful conversation with John Bowman, a seasoned expert in asset allocation and the CEO of Kaya. The discussion centers around the evolution of asset management strategies, particularly the transition from Modern Portfolio Theory (MPT) to the Total Portfolio Approach (TPA). Additionally, they explore the intricacies of liquidity in investment decisions, the maturation of family offices, the role of the Chartered Alternative Investment Analyst (CAIA) Association, and the future landscape of alternative investments.

Evolution from Modern Portfolio Theory to Total Portfolio Approach

John Bowman begins by contextualizing the long-standing reliance on Modern Portfolio Theory (MPT), developed by Harry Markowitz, which emphasizes diversification across asset classes to optimize risk and return. He notes that while MPT and its derivatives, like Strategic Asset Allocation (SAA) and the Efficient Frontier, have been foundational, the industry is now seeking more holistic methods.

"All of us have been kind of swimming in the water of modern portfolio theory for our entire careers." [01:45]

Bowman explains that the Total Portfolio Approach (TPA) moves beyond asset class optimization to align the entire portfolio with specific client goals, such as spending rates for universities or actuarial rates for public pensions. This shift allows for greater flexibility and customization, addressing the limitations of the traditional bucketed portfolio approach.

Rethinking Liquidity in Investment Portfolios

The conversation pivots to the role of liquidity in investment strategies. David Weisburd raises a critical point about liquidity being a net negative beyond a certain threshold, as it can tempt investors into making poor decisions during market downturns.

"Liquidity is actually net a negative because it tempts you into wrong actions." [00:00]

Bowman concurs, highlighting the industry's historical emphasis on liquidity and how it often leads to reactive behaviors that can harm long-term portfolio performance. He emphasizes that illiquidity can act as a safeguard against impulsive decisions driven by market volatility.

"There's some extent in which liquidity or illiquidity... protects us from the worst parts of ourselves." [07:59]

Changes in Family Office Investment Strategies

John Bowman delves into the evolution of family offices, which manage investments for affluent families. He notes that modern family offices are increasingly adopting the TPA approach, allowing them to explore diverse and unconventional investment opportunities without being constrained by rigid governance structures.

"Family offices are unique... they're not as bound to a governance structure." [14:13]

Bowman underscores the importance of relationship-building and networking in accessing top-tier private capital investments. He highlights the shift from traditional endowment models to more sophisticated, flexible investment strategies tailored to family-specific goals.

The Role of the CAIA Association in Alternative Investments Education

As CEO of the CAIA Association, John Bowman discusses the organization's mission to provide education and professional development in the alternatives space. He emphasizes that CAIA's curriculum is continuously updated based on industry needs and direct feedback from asset owners.

"We are trying to help all investment professionals see around the corner what formative strategies are coming next." [24:36]

Bowman highlights the importance of multidisciplinary education, enabling investment professionals to navigate the complexities of alternative investments and align their strategies with evolving market dynamics.

Current Trends in Allocator Portfolios (2025)

Bowman shares compelling data on current asset allocations among institutional investors. He reveals that alternatives now constitute approximately 21% of total investable assets globally, a significant increase from the mid-teens before the COVID-19 pandemic.

"Total investable assets AUM globally is about $120 trillion US. 25 trillion... is in what we would broadly call... alternatives." [31:29]

He breaks down the composition of alternatives, noting that private equity accounts for over 40% of this segment, followed by hedge funds and real estate. Bowman also points out the stark differences in allocations between high net worth individuals and larger institutions like endowments and sovereign wealth funds.

Democratization of Alternatives and Overcoming Barriers

The discussion moves to the democratization of alternative investments, making them more accessible to high net worth and ultra-high net worth individuals. Platforms like iCapital are pivotal in lowering investment thresholds and simplifying access.

"iCapital has really taken some of those earlier fund to fund approaches... institutionalized them and made them much more accessible." [34:49]

Bowman also highlights innovative investment structures, such as interval funds and new ETF offerings, which provide greater liquidity and flexibility, catering to a broader investor base. These advancements help bridge the gap between traditional public markets and alternative investments.

Regulatory Changes Impacting Alternatives

Regulatory developments, particularly the SEC's 506C rule, are reshaping the landscape for alternative investments by allowing fund managers to advertise more freely without stringent accreditation checks.

"The latest change regulatory from SEC 506C... they're within kind of the same regulatory scheme." [39:29]

Bowman cautions that while increased accessibility is beneficial, it also necessitates robust education and fiduciary responsibility to ensure that investors fully understand the implications of their investment choices, especially regarding liquidity constraints and long-term commitments.

"We've got to make sure that these advisors... know what they're buying." [39:29]

Future of the Alternatives Industry by 2030

Looking ahead, Bowman anticipates that alternative investments will become even more mainstream, especially among high net worth individuals who are currently under-allocated in this area. He projects that allocations to alternatives could soar to 25% or more of typical portfolios by 2030.

"Alternatives are largely mainstream now... a much more diversified portfolio with different access to risk premia and cash flow mechanisms." [46:45]

Bowman envisions a future where alternatives are seamlessly integrated into standard portfolio construction, driven by increased investor demand and continued innovation in investment products and platforms.

Importance of Multidisciplinary Understanding for Investment Professionals

Bowman emphasizes the necessity for investment professionals to cultivate a broad understanding of various asset classes. He argues that the blurring lines between different investments require a multidisciplinary approach to effectively manage and optimize portfolios.

"Systems thinking... play a massive role in how to think about an individual valuing a specific asset." [52:38]

By embracing a comprehensive knowledge base, investment professionals can better navigate the complexities of modern investments, align strategies with client objectives, and effectively compete in a rapidly evolving market.

Conclusion

The conversation between David Weisburd and John Bowman highlights a pivotal shift in the investment management landscape. Moving from the traditional Modern Portfolio Theory to a more holistic Total Portfolio Approach, the industry is adapting to the complexities of modern markets and the diverse needs of investors. Key takeaways include the nuanced role of liquidity, the maturation and evolution of family offices, the democratization of alternative investments, and the critical importance of multidisciplinary education and understanding for investment professionals.

As alternatives continue to gain prominence and accessibility, the future of asset management will likely be characterized by greater flexibility, tailored investment strategies, and an expanded role for education and professional development. This episode underscores the necessity for both investors and professionals to stay informed and adaptable to harness the full potential of the evolving investment landscape.
