Key Takeaways
- • Man Group's research reveals a fundamental trade-off in trend-following portfolio construction: investors prioritizing crisis resilience (crisis Sharpe) should favor traditional markets, while those maximizing long-term risk-adjusted returns (Sharpe ratio) should overweight alternative markets, with no universally optimal allocation.
- • Trend following addresses a critical diversification failure: equities, credit, real estate, and private equity share common economic drivers and tend to sell off simultaneously during recessions, making traditional diversification ineffective precisely when needed most.
- • The optimal market mix for trend followers depends entirely on investor objectives—there is no single solution applicable across all clients, requiring customized allocations based on whether defense during crises or maximum long-term returns is the priority.
- • Trend-following strategies can achieve positive expected long-run Sharpe ratios and positive expected crisis Sharpe performance simultaneously across diversified market combinations, providing both growth and tail-risk protection.
- • Investors seeking cash efficiency can construct highly liquid portfolios leveraging low margin requirements on futures and forwards, enabling capital-efficient implementation of trend-following strategies.
Summary
Man Group's research addresses a foundational question in trend-following portfolio construction: what is the optimal market mix for investors employing trend-following strategies across multiple asset classes? The analysis evaluates different combinations of traditional and alternative markets, assessing them against two distinct performance metrics—expected Sharpe ratio (risk-adjusted returns) and expected crisis Sharpe (risk-adjusted returns during market stress)—to determine which allocation best serves different investor profiles.
The research identifies a central paradox in diversification theory. While traditional portfolio construction incorporates equities, credit, bonds, private markets, real estate, and hedge funds under the assumption that low correlations enhance Sharpe ratios, this diversification fails at critical moments. Equities, credit, real estate, and private equity all depend on economic growth for price appreciation. When economic drivers break down during recessions or market dislocations, these supposedly diversified assets sell off together, eliminating diversification benefits precisely when investors need protection most. Trend following serves as a counterweight to this systemic risk.
Man Group's findings reveal that no single optimal market mix exists for all trend-following investors. Instead, the choice depends on explicit objectives. Investors prioritizing defensiveness and crisis-period performance should allocate toward traditional markets, while those focused solely on maximizing long-term Sharpe ratios should overweight alternative markets including commodities, real estate, and hedge funds. This trade-off requires investors to articulate their actual risk priorities rather than assume a universal solution.
The research also addresses capital efficiency, a critical concern for institutional investors managing leverage constraints. Trend-following strategies constructed with liquid futures and forwards can achieve highly cash-efficient portfolios by exploiting low margin requirements inherent to these instruments. This approach allows investors to maintain exposure to trend-following signals across multiple markets without tying up excessive capital, addressing a practical implementation challenge for large institutional allocators managing multiple mandates and capital constraints.
