Multi-asset portfolio construction in the age of uncertainty

Diversifying an investment portfolio with different asset classes helps to smooth out the return of your investments over time and reduces the dependency on the performance of a single asset class. But what should you do when bonds and equities fall at the same time?

Never too much or too little

Success in investing over the long-term isn’t just about picking winners. The safest way to grow your wealth over the long-term is to construct a portfolio that is able to navigate different market environments.

This means spreading your investments over as wide a terrain as possible, minimising your exposure should your stake in any single sector, company or fund take a tumble. Putting your money in as many pots as possible can help to capture new opportunities when they arise, too.

There may be chances to make strong short-term returns in individual sectors or companies – the recent surge in oil prices is a good example. But making bets on which stocks will perform well is a difficult game with uneven results. Even if your hunch proves correct, it’s difficult to time any anticipated rise or plunge correctly.

By adopting a balanced diversified approach (which means avoiding concentration of your wealth in one single asset class), your portfolio stands a better chance of achieving a stable return over time.

Fixed income comes under scrutiny

Government and corporate bonds are usually referred to as fixed income assets because they pay investors a set return until the maturity date, then get reimbursed. In a rapid rising environment for equity markets, we expect fixed income to underperform against equities, but the risk attached to them is much lower. A smartly diversified portfolio should have both, to avoid the sharp variability of performance that equity markets generate.

The recent performance of fixed income markets has generated some questions around the ability of that asset class to offer relevant diversification at a time where equity markets were falling. The reality is that fixed income investments have faced a perfect storm of unique market circumstances since the beginning of the year. The post-pandemic surge in inflation has been aggravated by the war in Ukraine (causing commodity prices to skyrocket), and by further lockdowns in China (which have further disrupted global supply chains). To keep up with these rapidly changing market dynamics, central banks have been forced to end their ultra-loose monetary policies and have therefore been raising their benchmark rates. As a result, fixed income investments have fallen in value. At the same time, equity markets have been selling off as well as a result of the consequences of the war in Ukraine and the risk of an economic slowdown following rapid change in monetary policy. So, against this backdrop of severe volatility, bonds and equities sold off at the same time and therefore, bonds failed to act as a safe haven.

Bonds still smooth out returns over time

When considering the value of a particular investment, it’s important to look at the bigger picture. Bonds didn’t offset falling equity values in Q1. But if we look at returns over a longer investment period, investors without any fixed income in their portfolio would have been worse off. The same was true during the depths of the Covid pandemic, when having fixed income smoothed out returns at a time when equities were down close to 35%.

Research has tracked the performance of bonds versus stocks since 1976. Of all the negative quarters we’ve seen for stocks in that time, bonds have outperformed equities 47 out of 50 times. This is one of the strongest correlations between asset classes that there is.

The simultaneous sell-off of bonds and stocks earlier this year came at a time when the world-turned abruptly and monetary policy and markets had to adapt to higher interest rates, soaring inflation and slow growth. Over the longer-term however, the value of fixed income in controlling overall exposure is unambiguous.

Risk management in uncertain times

Investors today are trading in an environment that the world has not seen since the 1980s. That era was another time of high inflation and low growth. Most investors weren’t active then and some weren’t even born.

We belief that risk tools are more important now than ever. It’s easy to say today that a portfolio should have more money in commodities, but that ignores the fact that commodities consistently performed poorly for the previous eight years. The top performing asset class has changed every year for the past decade.

Commodity prices were hurting for years due to bad PR and a shift towards renewables. Meanwhile, low interest rates were not favourable to value stocks – like banks – but fuelled the rise of the tech companies helping to digitise our societies. Few would have predicted the reverse in fortunes we are seeing today.

Winners rotate, so picking the right stock one year is no guarantee of success in the future. Investors in a single asset class can find themselves vulnerable when the winds change.

The bottom line

It’s important to have conviction and place bets when you believe that one asset class or manager will overperform, but balance is key. Success over the long-term means constructing a portfolio that is resilient and can perform well in multiple scenarios, not just one.

Putting all your eggs in one basket might work for a while. But if there is a market reversion – and there’s always one eventually – you will find yourself badly exposed without proper diversification. This strategic approach might mean that you’re never top of the pile in terms of returns over a short investment horizon, but it should also mean that you avoid the bottom of the pile as well. However, over the long term, being invested in a well-diversified portfolio means that you are much likely to achieve your long-term objective with limited stress.
