There’s no denying it’s been a challenging year for multi-asset investors. The simultaneous sell-off in both global equity and bond markets1 has led many investors to question the diversification benefits of multi-asset investing in the current market environment—leaving some wondering if balanced portfolios are even still fit for purpose.
As difficult as these times may seem, the case for multi-asset portfolios remains strong. With their historical track record of resilient returns, we believe balanced portfolios can continue to achieve their intended outcomes for disciplined investors who stay the course.
Much of the focus this year has been on the underperformance of fixed income in multi-asset portfolios. However, it is important to remember that the primary role of bonds in a well-balanced portfolio is to act as a ballast to equities over time, not as a driver of returns. Despite recent declines, we still believe bonds remain the best asset class to act as a counterweight to equities due to the historically low correlation between the asset classes, with bonds often acting as a buffer during periods of equity volatility. In fact, since the late 1980s, global bonds have consistently provided positive returns during the most severe global equity downturns, including the global financial crisis and Covid-19 pandemic2.
One of the key features of balanced portfolios has been their “all-weather” ability to deliver long-term outcomes across market conditions. The chart below shows the historical returns of 60/40 multi-asset portfolios following periods when equities and bonds have simultaneously declined over the last 100 years.
3-year performance of 60/40 portfolios after correlated bond and equity market losses, 1920–2022
Past performance is not a reliable indicator of future results.

Notes: Stocks: S&P500 returns, Bonds: 10-year US Treasury returns based on linear duration approximation. Returns calculated in USD with income reinvested. ‘Recovery’ defined as time taken for portfolios values to reach initial investment value ($1).
On average, the median portfolio (shown by the yellow line), recovered its initial losses after ten months and provided an average annualised return of about 9% over the subsequent three years. Even when we look at the worst-performing 60/40 portfolios, where the average drawdown was nearly 30%, it took approximately 2.5 years to recoup their losses, after which the portfolios provided an average annualised return of just under 7% for the next three years.
This ‘all-weather’ resilience is not limited to 60/40 portfolios and applies across the risk spectrum. For example, the same analysis of 20/80 portfolios found it took an average of six months to recover their initial losses, after which they provided average annualised returns of 7.6% for the next three years. This is largely because investors who stay the course after periods of low or negative returns benefit from being fully invested right when valuations are at their most attractive, leading to strong total returns when market conditions change.

Additionally, bonds have historically provided a buffer against recessionary sell-offs that often occur across riskier assets during periods of slowing economic growth. Thinking about the current market, investors who shift away from bonds now could end up locking in their losses while potentially damaging their ability to fully participate in the benefits of their bond holdings when market conditions eventually change.
Looking ahead, the outlook for multi-asset portfolios continues to improve, not decline, driven by higher expected future bond yields and lower share valuations3. According to the latest forecasts from the Vanguard Capital Markets Model (VCMM), the projected 10-year average annualised return for a 60/40 portfolio has increased considerably since the start of the year, from 1.9% to 4.5%—a rise of 260 basis points4.
Despite the glimmer of bluer skies on the horizon, it’s important to remember that Vanguard’s balanced portfolios are not designed to anticipate the timing of markets; instead, they ensure investors have broad market exposure through a global portfolio of diversified assets. Over the long-term, history has shown that aggregate returns are driven by a portfolio’s strategic mix of assets—and not by day-to-day tactical moves in portfolio construction5.
Still, at times like these, it is natural to want to take action to protect portfolios. Rather than trying to mitigate the potential impact of short-term market movements, advisers can take faith in the time-tested investment principles of strategic asset allocation that have served investors incredibly well over the long-term.

Important information
IMPORTANT: The projections or other information generated by the Vanguard Capital Markets Model regarding the likelihood of various investment outcomes are hypothetical in nature, do not reflect actual investment results, and are not guarantees of future results. Distribution of return outcomes from the VCMM are derived from 10,000 simulations for each modeled asset class. Simulations as at September 2022. Results from the model may vary with each use and over time.
The VCMM projections are based on a statistical analysis of historical data. Future returns may behave differently from the historical patterns captured in the VCMM. More important, the VCMM may be underestimating extreme negative scenarios unobserved in the historical period on which the model estimation is based.
The Vanguard Capital Markets Model® is a proprietary financial simulation tool developed and maintained by Vanguard’s primary investment research and advice teams. The model forecasts distributions of future returns for a wide array of broad asset classes. Those asset classes include US and international equity markets, several maturities of the US Treasury and corporate fixed income markets, international fixed income markets, US money markets, commodities, and certain alternative investment strategies. The theoretical and empirical foundation for the Vanguard Capital Markets Model is that the returns of various asset classes reflect the compensation investors require for bearing different types of systematic risk (beta). At the core of the model are estimates of the dynamic statistical relationship between risk factors and asset returns, obtained from statistical analysis based on available monthly financial and economic data from as early as 1960. Using a system of estimated equations, the model then applies a Monte Carlo simulation method to project the estimated interrelationships among risk factors and asset classes as well as uncertainty and randomness over time. The model generates a large set of simulated outcomes for each asset class over several time horizons. Forecasts are obtained by computing measures of central tendency in these simulations. Results produced by the tool will vary with each use and over time.
