Takahashi-Alexander Revisited: Modeling Private Equity Portfolio Outcomes Using Historical Simulations
By: Dawson Beutler, Alex Billias, Sam Holt, Josh Lerner and TzuHwan Seet
Abstract
In 2001, Dean Takahashi and Seth Alexander of the Yale University Investments Office developed a deterministic model for estimating future cash flows and valuations for the Yale endowment’s private equity portfolio. Their model, which is simple and intuitive, is still commonly used by investors to this day. However, the model possesses significant shortcomings, including its sensitivity to the assumptions necessary for the model to function and its failure to provide a range of possible portfolio outcomes. Both issues can result in investors developing overconfidence in forecasts, which can result in suboptimal—or even adverse—portfolio management decisions. To address these shortcomings, we propose a novel historical simulation approach that preserves the simplicity and intuition behind Takahashi and Alexander’s approach. However, our model, which leverages historical private equity cash flow data, requires no user assumptions and naturally provides a range of outcomes. We explore this model in some depth, highlighting the model’s power and flexibility across myriad use cases.
