Equity vs. Property: Institutional Investment Choices

The Role of Growth Assets

In the previous lesson, we focused on government and corporate bonds, which form the defensive core of many institutional portfolios. Their predictable cash flows are ideal for liability-driven investment (LDI), and their diversification benefits provide stability. However, in a world where liabilities are often growing (due to inflation or salary increases) and low interest rates can depress bond yields, relying on bonds alone may not be enough. Institutions need assets that can deliver higher returns over the long term. This is the role of growth assets, or as they are sometimes called, "return-seeking" assets.

Evaluating Equity Investments

Equities, or shares, represent a part-ownership in a company. Unlike a bondholder who is a lender, an equity holder is an owner, sharing in the company's fortunes—both good and bad.

Let's apply our five-point suitability framework to this asset class.

1. Risk and Return Profile

The primary reason to hold equities is for their superior long-term return potential, which comes from two sources:

• Capital Appreciation: The value of the shares increasing over time as the company grows.
• Dividends: A portion of the company's profits distributed to shareholders.

Professional investment consultants like Aon develop long-term capital market assumptions to guide institutional investors. These models break down expected returns into fundamental building blocks.

As the Aon report shows, the expected nominal return for global equity (around 7.4%) is significantly higher than for core fixed income (around 5.0%). However, this comes at the cost of much higher risk (volatility), at 18.7% versus 5.2%. This is the fundamental trade-off: to achieve higher returns, an investor must be willing to accept greater fluctuations in value. The risk is that poor company performance, economic recession, or market sentiment can cause share prices to fall dramatically.

2. Correlation and Diversification

Equities are pro-cyclical; their performance is positively correlated with economic growth. This means they do not provide the "flight to safety" diversification that government bonds offer during a crisis. However, significant diversification is possible within the equity asset class itself by investing across different geographic regions, industries, and company sizes.

For a statistician like yourself, the goal is to build a portfolio of equities where the assets have less than perfect correlation, thereby reducing the overall portfolio variance for a given level of expected return.

3. Cash Flow Characteristics (LDI)

Equities are a poor tool for the direct matching of liabilities. Dividend payments are discretionary and can be reduced or eliminated at any time, especially during economic downturns. This makes them unsuitable for the precise cash-flow or duration-matching techniques we discussed in the context of LDI. Instead, they are held in a "growth portfolio" intended to grow the overall pool of assets, thereby improving the institution's funding level (the ratio of assets to liabilities) over the long run.

4. Liquidity

Shares of large companies listed on major stock exchanges (e.g., the London Stock Exchange, New York Stock Exchange) are highly liquid. They can be bought and sold in large quantities almost instantaneously during market hours. This high liquidity is a significant advantage, allowing an institution to rebalance its portfolio or raise cash quickly if needed.

5. Regulatory and Accounting Treatment

Due to their high volatility, regulators impose significant capital charges on equity holdings. Under a framework like Solvency II, an insurer holding equities must set aside a substantial amount of capital to absorb potential losses. This makes holding equities capital-intensive compared to high-quality bonds. Furthermore, there is growing regulatory and public pressure for institutions to consider Environmental, Social, and Governance (ESG) factors in their investment decisions.

Investing in companies with poor ESG profiles can lead to reputational damage and long-term financial risk (e.g., a company with a large carbon footprint facing new regulations).

Evaluating Property Investments

Property, or real estate, refers to investments in physical land and buildings. For institutional investors, this typically means commercial property like office buildings, retail centres, industrial warehouses, and apartment blocks.

Let's apply our framework to property.

1. Risk and Return Profile

Property is often considered a hybrid asset, exhibiting characteristics of both bonds and equities.

• Return: The return comes from rental income (like a bond coupon) and capital appreciation (like equity growth). The rental income can be particularly attractive as leases often include clauses that link rent increases to inflation, providing a natural hedge.
• Risk: The risks are quite different from those of financial assets. They include loss of rental income due to tenants defaulting or vacancies, costs of maintenance, physical damage (e.g., from fire or flood), and illiquidity. The Aon report (LINK, Section 2) shows expected nominal returns for Core Real Estate at 5.5% with 15.4% risk, placing it in between bonds and equities on a risk-return spectrum.

A crucial emerging risk for property is climate change.

2. Correlation and Diversification

Property returns are driven by their own market cycle of supply (development) and demand (occupation). This means their returns are not perfectly correlated with either equities or bonds, making property a powerful diversifier in a multi-asset portfolio. The Aon report (LINK, Section 2) quantifies this by assigning Core Real Estate a global equity beta of just 0.30, indicating a low sensitivity to stock market movements.

3. Cash Flow Characteristics (LDI)

The stable, often inflation-linked rental income from a well-diversified portfolio of properties with high-quality tenants can be an excellent match for long-term, inflation-linked liabilities like some pensions. While the cash flows are less certain than those from a government bond, they are more predictable than equity dividends.

4. Liquidity

This is the single biggest disadvantage of direct property investment. Buying or selling a large commercial building is a slow, complex, and expensive process. This illiquidity means an institution cannot rely on selling property to meet sudden cash needs. This illiquidity risk is something for which investors demand a return premium.

5. Regulatory and Accounting Treatment

Valuing a property portfolio is challenging. Unlike shares, which have a live market price, properties are valued periodically by professional appraisers. This can "smooth" the reported returns, masking underlying volatility. Given your background in statistics, you'll recognize that this smoothed data requires careful handling; as the Aon report (LINK, Section 4) mentions, analysts must "de-smooth" historical returns to calculate a more realistic measure of volatility. Regulators are aware of these risks and apply significant capital charges to property investments.

A Look at Private Equity

Before we conclude, it's worth briefly touching upon private equity (PE), as it combines features of both asset classes we've discussed. PE involves taking ownership stakes in companies that are not publicly listed. Real Estate Private Equity is a major sub-class. This area has grown enormously and is a major destination for institutional capital.

The business model and its allure are well-explained in the following video.

Private equity promises very high returns—the Aon report (LINK, Section 1) forecasts over 10%—but it carries extreme illiquidity and complex risks. A contemporary problem is that of "zombie companies," where PE funds are stuck holding underperforming businesses they cannot sell.

This cautionary tale highlights that the pursuit of high returns in less transparent, illiquid markets requires deep expertise and carries substantial risks, a theme we will explore further in our next lesson.

Conclusion and Summary Framework

Equities and property are the essential growth assets in an institutional portfolio. They offer the potential for long-term returns that can outpace inflation and help a fund meet its objectives. However, they introduce higher volatility, greater complexity, and lower liquidity compared to bonds. The actuary's role is to understand and model these trade-offs to help determine a strategic asset allocation that balances the need for growth with the tolerance for risk.

Key Takeaways:

• Equities are the primary engine for capital growth, offering high long-term returns but also high volatility and poor cash-flow matching characteristics. Diversification across global markets is key to managing risk.
• Property acts as a hybrid asset, providing both an inflation-linked income stream and potential for capital growth. Its main benefits are diversification and liability matching, while its main drawback is illiquidity.
• Both asset classes are capital-intensive from a regulatory perspective and are increasingly scrutinized through an ESG lens.
• Private equity offers even higher potential returns but comes with extreme illiquidity and unique risks, such as being trapped in underperforming "zombie" assets.

Here is the requested summary framework comparing today's asset classes, which you can add to the one from our previous lesson.
