Factor: Move beyond style boxes

August 28, 2025
3 MIN READ 3 MIN READ

Traditional style boxes have long served as a basic framework for categorizing investments and grouping stocks by broad traits. While helpful for organization, this method often overlooks the deeper forces that drive risk and return in portfolios.

Factor investing advances portfolio construction by using rigorous research to identify the specific attributes such as value, quality, and momentum, that historically contribute to long-term performance. By focusing on these historically proven drivers, factor investing brings structure, transparency, and adaptability to portfolio design.

Where traditional approaches rely on broad categories, factor investing offers a more dynamic and disciplined path forward. Designed to align with persistent market forces, it enables investors to build portfolios that are potentially more resilient and adaptive, positioning factors as the next evolution in investment strategy.

There can be no assurance that performance will be enhanced or risk will be reduced for investment strategies that seek to provide exposure to certain quantitative factors. Exposure to such investment factors may detract from performance in certain market environments, in some cases for extended periods. In such circumstances, an investment strategy may seek to maintain exposure to the targeted investment factors and not adjust to target different factors, which could result in losses.

While the investment strategies are actively managed, the strategies’ investment process is expected to be heavily dependent on quantitative models and the models may not perform as intended.
