Active Extension has returned to institutional favor, with the majority of assets concentrated in systematic strategies designed to deliver benchmark outperformance within tightly controlled tracking-error parameters. Quantitative managers continue to dominate the category, while fundamental active extension remains comparatively underrepresented.

Against this backdrop, this paper examines the evolution of Active Extension and sets out a roadmap for fundamental managers to translate their research-driven insights into benchmark-relative returns that align with institutional allocators’ public equity objectives. For the purposes of this paper, fundamental managers are defined as those investing over medium- to long-term horizons, with positions informed by company-level research and typically held for quarters or years rather than weeks or months.

Inside the Paper: 

• Expressing more of the research: Active extension allows skilled fundamental managers to express negative stock views through short positions, enabling more of their research and forecasting skill to reach the portfolio.
• Controlling risks that consume tracking error: Systematic controls on market beta, factor exposures and individual stocks’ contributions to tracking error help focus active risk on stock-specific insights.
• Integrating skill with systematic construction: Partnerships between independent fundamental managers and systematic managers can translate stock-selection skill into benchmark-relative returns through disciplined sizing, risk management and execution.

The paper concludes by allowing readers to corroborate its conclusions through a guide of what to look for when assessing a fundamental active extension strategy.
