Managed futures: how CTA strategies work and their role as a portfolio diversifier
Managed futures is a strategy category that trades futures contracts across multiple asset classes—equities, bonds, currencies, commodities, and sometimes volatility—systematically and on both the long and short side. The strategies are run by commodity trading advisors (CTAs), a regulatory designation that covers both individual managers and funds. The defining characteristic of managed futures is the ability to profit in both rising and falling markets, which has historically made the strategy category one of the most reliable diversifiers for traditional equity and bond portfolios during periods of severe market stress.
How CTA strategies work
The majority of managed futures assets are managed using trend-following signals. These strategies identify sustained directional moves across dozens or hundreds of futures markets, take long positions in markets with upward trends and short positions in those with downward trends, and hold those positions until the trend reverses. The time horizon varies by strategy: shorter-term CTAs may hold positions for days to weeks; longer-term ones hold for months. The common thread is systematic rules applied consistently across a diversified set of markets.
CTAs access market exposure exclusively through futures contracts—standardised, exchange-traded instruments with defined expiry dates that are rolled forward as they approach maturity. Futures allow long and short exposure with equal ease, which is structurally important: a CTA can profit from a sustained equity bear market by holding short equity index futures, at the same time as holding long bond futures if rates are falling. This long/short, multi-asset structure is what produces the strategy's diversification benefit.
The diversification case
The empirical case for managed futures as a portfolio diversifier is among the strongest in alternative investments. Academic research by Fung and Hsieh (2001) identified "trend-following" as the dominant risk factor in CTA returns and documented that this factor has historically been negatively correlated with equity markets during their worst periods. Crisis alpha—positive returns during severe equity bear markets—is the strategy's defining characteristic. During the 2008 global financial crisis, managed futures indices produced positive returns while equity markets fell 40% to 50%. During the 2022 rate and equity sell-off, managed futures again produced strongly positive returns as the strategy captured downtrends in both bonds and equities simultaneously.
This defensive characteristic arises from the mechanics of trend following: sustained trends—including sustained downtrends—are the strategy's primary source of return. Severe bear markets are characterised by sustained downtrends across risk assets, which are precisely the conditions in which trend-following CTAs build large short positions and profit. The diversification is structural rather than coincidental.
Return characteristics
Outside of crisis periods, managed futures returns are more modest. The strategy tends to perform well during strong trending environments of any direction and struggles in choppy, range-bound markets where trends start and reverse before positions are established. Periods of low volatility, mean-reverting markets—characteristic of much of 2009 to 2019 in developed equity markets—produced subdued returns for trend-following CTAs even as equity portfolios performed strongly.
This pattern produces a distinctive return profile: positive skewness (occasional large gains, consistent smaller losses or modest gains in non-trending periods) and positive skewness of the overall return distribution. The strategy earns a premium for providing insurance-like payoffs during market stress—a premium that is real but requires patience during long periods of equity market calm.
Costs and access
Institutional managed futures funds historically charged high fees—a 2% management fee and 20% performance fee structure was common. These fees consumed a significant portion of the gross alpha. The growth of liquid alternatives and managed futures ETFs has brought cheaper access to systematic trend-following strategies, though the ETF implementations vary in their fidelity to the strategy's core mechanics. Futures roll costs—the cost of maintaining exposure by rolling expiring contracts to the next maturity—also affect net returns and should be examined when evaluating any managed futures vehicle.
Limitations
The strategy's defensive characteristic—profiting in bear markets—comes with the structural cost of modest underperformance during sustained bull markets. An investor who allocates 20% to managed futures in a diversified portfolio reduces upside participation proportionally in strong equity environments. The expected long-run return of managed futures is positive but lower than equities, so the allocation is justified by its diversification benefit and crisis alpha rather than by its standalone expected return.
The strategy can also experience extended drawdown periods during ranging markets. CTA drawdowns of 20% to 30% over one to three years are not uncommon before the next strong trending period restores the losses. Investors who exit during the drawdown—precisely when the strategy's diversification benefit is most needed—fail to receive the full return from the strategy's long-run profile.
