New Quantitative Approach to Private Equity Valuation
Alexander Lipton and Marcos Lopez de Prado, research heads at the Abu Dhabi Investment Authority, have introduced a new quantitative framework designed to value private equity investments. By moving away from traditional public-market arbitrage models, the researchers aim to provide portfolio managers with a disciplined, mathematical approach to assess illiquid assets based on individual risk tolerance and utility maximization.
Why current private equity valuation methods fall short
Traditional valuation models often rely on arbitrage pricing theory, which assumes assets are traded continuously. According to Lopez de Prado and Lipton, this approach is fundamentally flawed for private equity because these assets lack the liquidity required for instantaneous trading. Without a unique price to identify identical payoffs, investors cannot perfectly hedge these positions using conventional public-market tools.
The absence of reliable valuation methods has historically left portfolio managers guessing regarding the appropriate allocation for private assets. As global interest in private equity grows alongside a surge in high-profile IPOs, the difficulty of accurately predicting the evolution of underlying company assets has become a significant hurdle for institutional investors.

How the new three-asset model functions
The proposed framework utilizes a two-stage approach that incorporates a risk-free investment, a public investment, and an illiquid private asset. Instead of seeking a single, universal fair market value, the model focuses on “indifference pricing,” which calculates what an asset is worth to a specific investor based on their own risk preferences.
In the first stage, the model determines the optimal allocation for non-tradable private assets. The second stage sets sub-allocations to balance these holdings against liquid, tradable assets. According to Lipton, this system serves as a quantitative tool to resolve qualitative questions, allowing investors to account for non-linearity that traditional methods frequently overlook.
Expert Insight:
The move toward utility-based pricing suggests a shift in how institutional investors view private equity. By prioritizing an investor’s specific risk tolerance over the pursuit of a hypothetical “market price,” firms may be better positioned to manage the uncertainty inherent in private markets, potentially reducing model risk in volatile cycles.
What may happen next for private equity valuation
The authors state that their research on private equity is ongoing. Future developments may include the integration of digitization and tokenization with their existing quantitative methods to further refine valuation accuracy. Lopez de Prado noted that future efforts will likely focus on “disentangling risk” by weighing three specific dimensions: market risk, model risk, and broader uncertainty.
As these quantitative frameworks gain adoption, portfolio managers may find it easier to justify private market allocations during periods of market volatility. The continued study of post-IPO company dynamics could also lead to more precise predictions regarding how private assets evolve before and after they enter public markets.
Frequently Asked Questions
What is the main limitation of current private equity valuation?
According to Lipton and Lopez de Prado, current methods borrow from public markets and rely on arbitrage pricing, which requires continuous trading that does not exist in the illiquid private equity sector.
How does the new framework differ from traditional models?
The new model uses utility maximization and indifference pricing rather than seeking a single, universal fair market value, allowing it to account for an individual investor’s specific risk tolerance and allocation size.
What are the next steps for this research?
The researchers plan to combine quantitative methods with digitization and tokenization to improve the understanding of private equity valuations and better disentangle market risk, model risk, and uncertainty.
How might these quantitative models change the way you view long-term asset allocation in your own portfolio?
