SI319: The Surprising Factors Behind CTA Performance: Is Less More? ft. Rob Carver
Top Traders Unplugged
Navigating the Complexities of Regression in CTA Analysis
This chapter explores the intricacies of regression analysis in assessing CTA performance, highlighting issues with long time frames and market variability. It introduces the lasso technique for simplifying regression and critiques the reliance on in-sample testing while advocating for a more practical approach to emulate CTAs.
Today, we delve into the nuances of systematic investing with Rob Carver, focusing on the concept of replication in trend-following strategies. The discussion contrasts different approaches to replication, highlighting the potential pitfalls of return-based methods that attempt to mimic established indices. We emphasize that simply increasing the number of markets in a portfolio may not lead to better diversification, as it could ultimately expose investors to similar risk factors. We also explore the implications of a recent paper from Newfound Research, which uses random data to challenge traditional views on replication effectiveness. With insights on factors influencing CTA performance and the importance of understanding true diversification, this conversation offers valuable perspectives for both investors and practitioners in the systematic trading space.
