CTA Design Impact Monitor: Choices matter as CTA leadership shifts and dispersion persists

CTA model design and its impact on performance

Trend following strategies have their roots in commodity futures, where some of the

earliest systematic approaches were applied. As a result, they became known as

Commodity Trading Advisors, or CTAs. Today, however, global futures markets span

equities, fixed income, currencies, and commodities. To capture diversification across

these asset classes, trend following strategies have expanded their investment universe,

though they are still commonly referred to as CTAs or more broadly as Managed Futures.

While these strategies are rules-based and systematic, they are not uniform.

Implementing a trend following model requires a set of core design choices, including

the assets included in the universe, the speed at which signals react, and how risk is

allocated and scaled over time. These choices are fundamental to model construction

and can lead to meaningful differences in realized performance, particularly in more

volatile or rapidly changing market environments where positioning diverges across

models.

This report focuses on understanding those differences. We develop a framework to

isolate and quantify the impact of key design choices on CTA performance. By holding all

else equal and varying individual components of the model, we attribute performance

differences directly to underlying construction decisions, providing a clearer view of

what drives dispersion across managers.

Because CTA strategies are systematic, they can be modeled. Using observable market

data and well-defined rules, we construct representative models that approximate

industry behavior. This allows us both to replicate broad trends in CTA performance and
