Inflation is a key culprit, forcing central banks into a difficult balancing act as they try to manage rising prices while also supporting economic growth. This is resulting in more policy uncertainty across regions and, as our global macroeconomics team has argued, it is likely to drive greater cyclicality and dispersion in economic outcomes going forward. Also contributing to the volatility are the unprecedented surge in government debt burdens and concerns about institutional credibility since the pandemic, as well as geopolitical tensions in many parts of the world.
All of this may add up to more boom/bust and bull/bear cycles going forward. One way investors may be able to make their portfolios more resilient is by replacing some of their equity exposure with equity long/short hedge funds. By design, these funds tend to have less equity market exposure (“beta”) than long-only equities. In addition, long/short hedge funds tend to have dynamic exposure to the equity market, meaning they can bring their “net” long exposure down to help protect capital during sell-offs. With these potential advantages, we would expect equity long/short hedge funds to meaningfully outperform long-only equities in a deep sell-off (though they would likely be down, perhaps significantly, in the event of a sudden and rapid market collapse).
3. Rich valuations
Strong market gains, especially in US mega-cap technology stocks, have left investors to contemplate the potential downside of high valuations and extreme levels of index concentration. As of 30 October 2025, for example, the trailing PE ratio of the S&P 500 was at nearly the 96th percentile for the past 20 years. The only sustained period with a higher result was the post-pandemic stretch from August 2020 to July 2021.
We think hedge funds can help by providing a return source that does not depend on market beta. While we recognize that some investors may be skeptical about hedge funds, given some cases of challenging performance over the past decade, we think we’ve entered an environment that may be more fertile for hedge funds, including the higher levels of macro volatility and interest rates noted above. Our research suggests these are among the factors that have historically driven stronger periods of hedge fund performance.
What to do next: Implementation ideas
A key question for investors contemplating the role hedge funds can play in today’s market is how to incorporate them into an existing portfolio. In our latest research, we look at how different allocations to multi-strategy and equity long/short funds could enhance a traditional portfolio. We also discuss the all-important manager selection process. Read more in our new paper, Are hedge funds the missing ingredient?
