Implementing Systematic Risk Premia, Factor-Based Strategies, and Sector Rotation with ETFs
A new paper outlines a practical method for building systematic investment strategies with exchange-traded funds (ETFs), aimed at long-only investors such as family offices. The approach lets investors adjust portfolios to reflect views on risk premia, style factors, and sector trends, while keeping risk close to a benchmark and avoiding return forecasts. Using risk parity and minimum-variance weighting, the method enables flexible, transparent ETF portfolios, though it depends on historical data and ETF liquidity in volatile markets.
What it examines
This paper presents a practical method for long-only investors to use ETFs for systematic investment strategies. It enables portfolio managers to tilt portfolios toward specific risk premia, factors, or sectors, while controlling risk relative to a benchmark, without needing explicit return forecasts.
What it concludes
The approach allows investors to express market views, manage risk, and implement factor tilts using liquid, low-cost ETFs. It is adaptable, scalable, and suitable for family offices and wealth managers. Applications include portfolio customization, risk management, and sector rotation. Future research may refine constraints and extend to other asset classes.
