"Understanding the typical behaviour of different investments through the economic cycle is key to building all-weather portfolios."
Multi-asset product manager, Vanguard, Europe
The euro area and the UK economies are slowing down and both markets look on course to enter recession (the euro area may already be in one) as we head into 2024. The outlook might be concerning to some, but there are portfolios designed to deliver value throughout the different phases of the economic cycle.
Long-term investors will experience various economic and market conditions throughout their investment journey, which is why it’s practical to construct portfolios that can withstand economic downturns as well as capture returns when markets are rising. Such strategies are sometimes referred to as ‘all-weather’ portfolios.
Understanding the typical behaviour of different investments through the economic cycle is key to building all-weather portfolios—and with recession looming, it seems a good time to revisit the fundamentals of investing for the long term.
In this article, we explore the historical patterns of asset class returns at different points of the economic cycle with a view to constructing portfolios that deliver enduring value for clients.
Building an all-weather portfolio hinges on investors accepting the risk/reward trade-off of different investments and the cyclical nature of economies and markets. The most obvious way market dynamics are considered in portfolio construction is through a strategic allocation1 to global equities and global bonds.
That’s because, put simply, stock markets tend to outperform bonds when the economy is growing and business conditions are favourable, while bond prices tend to rise when the economy contracts (or is expected to)—or at least when stock markets fall for a sustained period of time.
The chart below is based on US data, but the findings are relevant across global markets—that stock markets tend to drive market returns when the economy is expanding. Global equities posted an annualised return of almost 12% (in US dollar terms) in non-recessionary environments between January 1988 and the end of December 2022, with global bonds returning an average of 5.1% in those periods.

In a recession (as defined by the National Bureau of Economic Research), the picture changes significantly, as illustrated in the next chart, which shows that bonds tend to outperform equities during recessions.
The rise of bond markets during periods of economic weakness reflects a trend often referred to as a ‘flight to quality’ or ‘flight to safety’ as investors seek the relative safety and reliability of high-quality fixed income.

Some observers might see the findings as encouragement to shift their clients’ asset allocations towards fixed income at the expense of equity market exposure when a recession is looming, but a key point to note is that our analysis benefits from hindsight. In other words, we don’t know exactly when a recession will start or finish until several months after the fact, making market timing incredibly difficult – and risky.
Another reason investors should beware abandoning stock markets during a downturn is that our research found global equities tend to recover before a recession ends2.
In each of the seven US recessions between 1973 and 2021, we found that the S&P 500 began to recover, in US dollar terms, while the economy continued to shrink.
We also analysed the timing of equity market rallies during the same period and found little observable pattern. The earliest recessionary recovery in stocks began just two months into the brief economic downturn of 2020, while the latest recovery started 16 months into the recession of 2007–2009.
Even though the mid-recession rally may not be quite enough to bring the average equity return up during an economic downturn, the next chart shows how equities tend to compensate patient investors in the six months after the end of a recession. The data show that global equities returned an average of 27% (in US dollar terms) in the six months following a recession.

The key message from this analysis, we think, is that rather than trying to time markets, investors are often rewarded by being patient and maintaining a strategic allocation to global equities and global bonds throughout their investment journey.
A key component of an effective all-weather portfolio is broad diversification across global equity and bond markets. By spreading investments across regions and sectors, investors can reduce risk while capturing gains from the best-performing securities at any given period.
As the data below highlight, it’s difficult to say exactly which sub-asset class across equity and bond markets will perform well from year to year. We only need to look at the results of 2022 to consider the dangers of concentrating investments in one region or sector, with UK equities the only asset class to deliver a positive return last year (in GBP terms).

Vanguard’s multi-asset solutions are designed with a strategic allocation to global equities and global bonds which is broadly diversified across markets, with the aim of delivering value through various economic and market environments.
The key to unlocking the value of all-weather multi-asset portfolios is to find the most suitable asset allocation strategy, based on each client’s attitude towards risk, their goals and investment horizon—and ultimately staying the course through the ups and downs of markets.
1Strategic asset allocation involves the deliberate division of investments across different asset classes to manage risk while targeting either a specific or broad long-term investment objective—and rebalancing the portfolio back to this pre-set allocation periodically. There are two primary approaches to strategic asset allocation: fixed-target allocation (steady), whereby the proportion invested in global equities and global bonds is consistent and maintained through regular portfolio rebalancing; and time-varying allocation (dynamic) whereby the mix of assets changes over time to optimise portfolio returns according to the portfolio’s objective.
