- • Bank-funded leveraged lending has collapsed as a proportion of total funding, dropping from 72% three decades ago to just 25% in 2024, reflecting fundamental reallocation of capital toward private markets and alternative funding mechanisms.

Summary
Cambridge Associates, a global investment firm with over 50 years of institutional investing experience, presented strategic guidance on private investments and long-term portfolio construction. The presentation, delivered by Andrea Auerbach, addressed fundamental portfolio construction challenges and the role of private markets in modern institutional investment strategy.
The core thesis reflects a structural shift in capital markets. The number of large private companies in the U.S. has grown 46% over the past 30 years, while public company listings have declined 24% during the same period. This secular trend extends across developed economies globally. Simultaneously, corporate financing behavior has fundamentally changed: bank-funded leveraged lending represented 72% of market activity 30 years ago but declined to just 25% by 2024, indicating massive capital migration toward private funding sources.
Traditional portfolio construction anchored to 60% equity and 40% bond allocations faces inherent concentration risks. Equity indexes weighted by market capitalization concentrate exposure in the largest companies and sectors, while bond indexes weighted by issuer create unintended duration and credit concentration. These structural limitations mean conventional diversified portfolios remain overexposed to two primary return drivers: equity beta and bond duration. The presentation argues that institutional investors must broaden their aperture beyond public benchmarks to capture evolving return sources.
Private markets have emerged as critical portfolio building blocks for institutional allocators. Cambridge Associates serves pension plans, endowments, foundations, healthcare systems, and private clients, offering outsourced CIO services, non-discretionary portfolio management, and alternative asset class mandates. The presentation framework integrates private equity, venture capital, private credit, and liquidity considerations into cohesive long-term portfolio strategy. As the proportion of investable opportunities shifts from public exchanges to private capital formation, investors with access to diversified private market exposures can better participate in the full spectrum of economic value creation and potentially enhance risk-adjusted returns through systematic exposure to alternative return drivers and risk factors unavailable in traditional public markets.
