Key Takeaways
- • Hedge fund correlations with U.S. equities range from 30% (global macro) to 72% (long-short equity), significantly limiting the diversification benefits many investors expect; correlations with fixed income are generally lower (5% to 40%), depending on strategy.
- • Traditional and factor investing strategies account for the majority of hedge fund returns, meaning most hedge fund performance is replicable through passive or factor-based exposure rather than fund-specific alpha generation.
- • Some hedge fund-specific strategies do generate incremental returns beyond traditional and factor exposures, creating a meaningful performance differential that justifies active scrutiny of manager selection.
- • Fund selection emerges as a critical investment decision, particularly given the wide performance dispersion across managers within the same strategy and the prevalence of beta-driven returns in hedge fund portfolios.
- • Diversification benefits vary substantially by strategy and asset class, requiring investors to conduct strategy-specific correlation analysis rather than treating all hedge funds as uncorrelated portfolio diversifiers.
Summary
MSCI's October 2018 analysis challenges a core assumption underlying many institutional hedge fund allocations: that hedge funds provide meaningful diversification from traditional equity and fixed income portfolios. The research reveals that average hedge funds maintain significant exposures to conventional market risk factors, with correlations to U.S. equities varying widely across strategies.
The quantitative analysis examined major hedge fund investment strategies using the MSCI Fund Model, with forecasts dated December 2017. Results demonstrate that equity correlations are far from negligible. Long-short equity strategies exhibit the highest correlation to U.S. equities at 72%, while global macro strategies—historically marketed as offering the greatest diversification—still maintain a 30% correlation. Fixed income correlations present a more favorable diversification picture, ranging from a low of 5% in long-short equity to 40% in global macro, but these relationships remain meaningful and strategy-dependent.
The critical insight from MSCI's findings concerns the source of hedge fund returns. Traditional and factor investing strategies—exposures that can be obtained far more cheaply through passive or systematic factor implementations—typically account for the majority of a typical hedge fund's total returns. This means that much of what investors pay premium fees to access is substantially replicable through liquid, low-cost alternatives. However, the research also identifies a meaningful exception: certain hedge fund-specific strategies do generate incremental returns beyond their traditional and factor exposures, suggesting genuine alpha exists in select managers and approaches.
This dual finding frames hedge fund selection as a high-stakes decision. Given that most hedge funds operate with substantial beta exposure to traditional assets, and given wide performance dispersion across managers within the same strategy class, the choice of which specific funds to allocate capital to becomes paramount. Investors must move beyond the assumption that hedge funds as an asset class provide reliable diversification, and instead conduct rigorous due diligence to identify managers whose strategy-specific insights and execution capabilities genuinely add value beyond tradable market factors. The research underscores that passive exposure to a hedge fund strategy index may capture substantial traditional beta at premium fees, while active manager selection focuses capital on funds most likely to generate true alpha.
