Different diversifiers shine in different conditions
Each market-moving event has different causes, and idiosyncratic factors that influence investor behaviour.
The perfect diversifier would show consistent positive, uncorrelated returns over time, have high sensitivity to volatile markets, and perform particularly well during market drawdowns.
Unfortunately, the perfect diversifier does not exist. Instead, we construct a suite of diversifiers that explicitly targets and considers each of these three characteristics. When done well, diversification can help us to build portfolios and funds capable of dealing with unforeseen risks.
Our investment approach currently includes bonds and (in certain portfolios) liquid alternatives, gold, and targeted currency diversification.
Gold is the most recent addition to our alternatives basket. The gold market is small relative to global bond and equity markets, and so an increase in demand from a particular investor type can cause a meaningful shift in supply/demand dynamics. In recent years, this demand shift has come from central banks.
US dollar-denominated reserves, adjusted for valuation effects, are now lower than gold reserves in the global central banking system for the first time since the International Monetary Fund started publishing this data in the late 1990s, according to Bloomberg. Given these fundamentals, we continue to think that, in the current environment, an allocation to gold as part of a broader diversifying portfolio is warranted.
Taking a long-term approach
Predicting the performance of diversifiers in the short term can be difficult. For example, in the first month of equity market corrections over the last 20 years, gold has experienced positive returns 50% of the time. However, if we extend the timeframe to look at the 12 months following the start of the correction, gold has experienced positive returns 90% of the time.
The reason for this is likely because, early in a market correction, gold prices can come under pressure as investors seek to raise cash. This can require the selling of positions that have previously been resilient, including gold. Overreacting to, and judging, diversifiers based on short-term moves could lead to suboptimal decision-making, and less robust portfolios over time.
Protecting the downside
We do not wait until volatility hits before we worry about diversification: the decisions we make during times of market stability are exactly what can protect us during market turmoil. In January of this year, our positioning was more diversified than it had been for some time, with positions across G7 government bonds, diversified currencies, plus gold and liquid alternatives where appropriate for our clients. This stood portfolios and funds in good stead during volatility triggered by escalations in the Middle East.
Aiming to ‘protect on the downside’ is fundamental to our investment philosophy. In our view, downside protection does not depend on perfectly forecasting the next recession, oil shock, or fiscal event. Instead, our approach is centred on building portfolios and funds that are sufficiently robust to withstand a wide range of scenarios as they emerge. In the first half of the year, this at times required a broader and more flexible approach to diversification. We expect this technique to stand us in good stead in the second half of 2026.
Diversifiers now play a vital role in protecting against equity drawdowns and managing risk in multi-asset portfolios, as Mathilde Helaine demonstrates later in this Outlook. And in such a fast-paced global market, we need a wide range of different diversifiers.
As we enter the second half of 2026, bonds continue to have an important role to play alongside equities in our portfolios. However, our approach to diversification reduces our reliance on one diversifier and seeks to ensure our portfolios can remain resilient to a range of outcomes, including both those we can foresee and those we cannot.
