Enhancing Trend Following Performance using System Diversification

Enhancing Trend Following Performance using System Diversification While it’s common to discuss diversification in terms of the wide range of markets trend followers engage in, diversifying the systems or models they use is equally crucial. While it is common to discuss diversification in terms of the wide range of markets trend followers engage in, diversifying the systems or models they use is equally crucial. This approach not only helps in lowering portfolio volatility but also enhances the potential to capitalize on exceptional market movements, often referred to as ‘Outliers’. Let’s delve into some key aspects of system diversification, specifically the practice of applying various trend-following models to the same market. By exploring this strategy, I aim to outline its advantages and disadvantages, especially when contrasted with the more traditional approach of applying a single system to a single market. This comparison will shed light on how different models can complement each other to capture diverse market dynamics, offering a broader perspective on effective diversification strategies. System Diversification Allows you to Reduce Portfolio Volatility System diversification in trend following involves deploying a variety of models within the same market to create a composite of strategies that can offset correlations and enhance the ability to tap into diverse market opportunities. This approach contrasts with dedicating 100% of capital to a single strategy within a single market, which typically results in a return stream characterized by the volatility and performance tied to how that specific system interacts with market trends over time. By allocating, for instance, 10% of capital to each of 10 distinct trend-following models within the same market, an investor generates multiple return streams. Each stream reflects the unique way its corresponding model engages with the market’s trending behaviours. This ensemble of models produces a set of results with inherent correlation offsets, leading to reduced overall volatility and potentially capturing a broader array of trending opportunities due to the reduced reliance on any single model’s selection bias. The traditional method of selecting a single trend-following model based on its historical performance introduces a risk of selection bias and curve fitting, as the chosen model is typically the one that performed best in backtesting. This can lead to overoptimization to past market conditions, reducing the model’s effectiveness in future, unforeseen market environments. In contrast, employing an ensemble of models mitigates this risk, as the collective approach is less likely to be overfitted to historical data and more adaptable to a range of market conditions. Each model within the ensemble adheres to the core principles of trend following—cutting losses quickly while allowing profits to run—but is uniquely configured to respond to different trend durations and patterns. This diversity within the ensemble equips it to handle a wide variety of trend scenarios, making it metaphorically the most ‘flexibly fitting’ approach in the trend following space. Using System Diversification to Have More Direct Control over Portfolio Correlations System diversification offers a strategic approach to managing correlations, distinct from the inherent correlations present between different markets. While market correlations are largely beyond our control, dictated by external market dynamics, system diversification allows for deliberate manipulation of correlations through the design and configuration of trading systems. An illustrative example of this control is the concept of a perfect hedge within a single market, where buying and selling a contract simultaneously can, theoretically, result in perfectly negative correlations, nullifying market risk aside from transaction costs. However, while a perfect hedge demonstrates the potential to neutralize market risk, it does not inherently generate long-term returns. To leverage system diversification for returns, the approach needs refinement. Systems must be designed with a persistent edge, and when combined, they should significantly dilute market correlations. Employing an ensemble of systems enables the strategic activation and deactivation of individual systems based on specific entry criteria, ensuring that they operate independently of one another at different times. This staggered activation contributes to a composite system with more uncorrelated characteristics, enhancing the ensemble’s ability to navigate diverse market conditions effectively. System Diversification Allows you to Expand in Terms of Market Diversification The effectiveness of capturing opportunities from market trends hinges on two pivotal elements: the inherent trends within the market and the capability of our trading systems to seize these opportunities. Utilizing an ensemble of trend following systems broadens our ability to identify and exploit Outliers across the market’s time series, enhancing the potential for significant returns. An Outlier trade is the product of the dynamic interplay between distinctive market trends, which may themselves be Outliers, and the specific design and responsiveness of our system’s architecture to these market conditions. Certain systems, by virtue of their design characteristics, are particularly adept at capitalizing on market trends, achieving exceptional reward-to-risk outcomes. Incorporating a variety of systems into an ensemble not only increases the likelihood of engaging with Outlier opportunities but also introduces a diverse range of responses to similar market conditions. Minor differences in system design can result in one system capturing an Outlier trade while another might not, underscoring the value of diversity within the ensemble. The real power of a system ensemble becomes evident when applied to highly correlated markets. For example, when an ensemble of Trend Following systems is employed across two markets with high correlation, such as Brent Oil and Crude Oil, the resulting return streams from the ensemble exhibit significantly lower correlation than the markets themselves. This reduction in correlation is a testament to the ensemble’s ability to diversify risk and enhance returns, even in markets that traditionally move in tandem. This unique attribute of system diversification allows for a significant expansion in market engagement within a portfolio context. By effectively dismantling the inherent market correlations through the use of system ensembles, traders can vastly increase the number of markets they participate in. System diversification, therefore, not only mitigates risk through broader market coverage but also amplifies the potential for capturing lucrative market movements, paving the way for a more robust and resilient trading strategy.
