How should I determine my allocation to illiquids?

Distinctly different investments need a distinctly different approach… How can I ‘’do the math” and compare illiquid investments, such as real estate and private debt, with traditional asset classes such as equities and bonds? With no trading and no benchmarks that incorporate all types of illiquids, we have minimal performance and risk data, while the industry has not yet agreed on how to estimate an appropriate allocation to illiquid assets.

…to deliver distinctly different results

Find out the answers in our latest educational paper where we offer our perspective on sizing optimal exposure to illiquid assets for global multi-asset portfolios. Getting it right can bring an array of potential rewards for your portfolio, including valuable diversification benefits, a superior risk-return profile and a higher potential for better return.

Essential due diligence

As our graph shows, Illiquid assets have performed very well over the past few years, outpacing global equities. However, monthly returns often hide high volatility and overestimate correlation with other asset classes. Therefore, careful assessment of these assets’ risk/return profile is essential.

So where do you start sizing illiquid allocations? Discover more about the key elements of this process, why they are important and how they fit together:

  • Investor’s circumstances and long-term objectives
  • Microeconomic and financial variable forecasts, as well as hidden risks
  • Return generation and risk mitigation projections expressed through mean variance optimisation
  • Modelling returns for different types of multi-asset portfolios, across different risk portfolios (such as conservative, balanced and aggressive)
  • Quantifying the impact of illiquid allocations of different sizes on the overall portfolio volatility
