Building a Better Portfolio: Balancing Performance and Liquidity


  • GIC and PGIM have collaborated to develop the OASISTM (Optimal Asset Allocation with Illiquid Assets) Framework to help guide private market investors in their portfolio allocation decisions.
  • The search for higher returns and better diversification has led many institutional investors to allocate more capital to private assets. 
  • The framework helps investors formulate a private asset commitment strategy to manage private asset exposure, and model how different scenarios could affect their portfolio’s performance and liquidity.

EXECUTIVE SUMMARY

The search for higher returns and better diversification has led many institutional investors to allocate more capital to illiquid private assets. This has come at the cost of decreasing portfolio liquidity, as private assets are not easily sold in a short period of time and may be unable to meet immediate portfolio liquidity demands. At the same time, private asset investors may encounter additional and often hard to predict liquidity demands when GPs make capital calls stemming from prior commitments. Investors need to have a strong understanding of how the liquidity characteristics of private assets impact their portfolios.

Investors are increasingly faced with the difficult choice between potentially higher returns and greater liquidity. Given market uncertainty, the risk of failing to meet liability obligations or failing to capture attractive opportunities during market dislocations further complicates the decision. What is the right amount of private assets in one’s portfolio?

Leveraging the cross-asset research capability and experience of GIC EIS and PGIM IAS, we have enhanced and expanded PGIM’s asset allocation framework (OASIS™ – Optimal Asset allocation with Illiquid Assets) to formally integrate liquidity measurement and cash flow management into a multi-asset, multi-period portfolio construction process.

Investors can use this framework to analyze how allocations to illiquid private assets (a top-down decision), in combination with their private asset commitment strategy (a bottom-up decision), affect their portfolio’s ability to respond to liquidity demands (Figure 1).

Specifically, this framework can help investors address the following key asset allocation questions:

  1. How to formulate a private asset commitment strategy to manage private asset exposure and the uncertainty in timing and magnitude of cash flows over time?
  2. What should be the desired allocations (public vs. private, public passive vs. public active) given the investor’s liquidity risk tolerance?
  3. How would various market scenarios impact the portfolio’s liquidity and performance?

The OASIS framework is modular (Figure 2), with each underlying component customizable by the investor.

First, it begins by simulating the returns and risk of public and private assets in a multi-asset portfolio. The simulation can incorporate an investor’s own capital market assumptions. It also allows investors to express their views on future private asset performance (relative to public assets) and their fund-selection skills which can be an important performance driver. In addition, the framework introduces cash flow modelling which is consistent with and responsive to the underlying market environment.

Second, the framework uses the investor’s portfolio structure that specifies a “waterfall” rule for sourcing liquidity: Which assets to sell to meet a liquidity demand, starting with those that are the least disruptive and costly.

Last, bringing it all together, we apply the framework and show examples of how investors can analyse their portfolio’s performance and liquidity. This flexible and customizable framework can incorporate investors’ own assumptions regarding:

  • Public asset performance and risk (beta and alpha);
  • Private asset commitment strategy;
  • Total portfolio cash flow needs and liquidity supply waterfall;
  • Penalty for various liquidity events;
  • Private asset performance and risk (relative to public assets) and fund-selection skill.

These materials are for informational or educational purposes only. In providing these materials, GIC Private Limited and its affiliates and PGIM are not acting as your fiduciary.

Alternative investments are speculative, typically highly illiquid and include a high degree of risk. Investors could lose all or a substantial amount of their investment. Alternative investments are suitable only for long-term investors willing to forego liquidity and put capital at risk for an indefinite period of time. Equities may decline in value due to both real and perceived general market, economic and industry conditions. Investing in the bond market is subject to risks, including market, interest rate, issuer, credit, inflation risk and liquidity risk. Commodities contain heightened risk, including market, political, regulatory and natural conditions and may not be suitable for all investors. The use of models to evaluate securities or securities markets based on certain assumptions concerning the interplay of market factors, may not adequately take into account certain factors and may result in a decline in the value of an investment, which could be substantial.

The analysis in the paper is based on hypothetical modelling. There is no guarantee, and no representation is being made, that an investor will or is likely to achieve profits, losses or results similar to those shown. Hypothetical or simulated performance results are provided for illustrative purposes only and have several inherent limitations. Unlike an actual performance record, simulated results do not represent actual performance and are generally prepared through the retroactive application of a model designed with the benefit of hindsight. There are frequently sharp differences between simulated results and actual results. In addition, since trades have not actually been executed, simulated results cannot account for the impact of certain market risks such as lack of liquidity. There are several other factors related to the markets in general or the implementation of any specific investment strategy, which cannot be fully accounted for in the preparation of simulated results and all of which can adversely affect actual results.
