Summary
AQR Capital Management is expanding its product suite with a new long-short equity fund that marries environmental, social, and governance (ESG) investing principles with quantitative short-selling strategies. The AQR Sustainable Long-Short Equity Carbon Aware Fund (QNZNX) will construct portfolios of U.S. and foreign equities using ESG criteria as a foundational framework while integrating carbon awareness into its factor-based selection process.
The launch reflects a broader evolution in ESG investing toward more sophisticated, multi-factor approaches. Rather than employing simple positive or negative screening methodologies, AQR's model uses quantitative analysis to identify both long and short opportunities based on ESG and carbon metrics. This strategy allows institutional investors to gain exposure to sustainable investing themes while maintaining the risk management and diversification benefits inherent in long-short structures.
Cliff Asness, AQR's co-founder and chief investment officer, continues to position the firm as a leading voice in quantitative asset management. AQR's existing quant strategies have demonstrated resilience and strong returns; the firm's long-short Delphi equity fund, managing $4.1 billion in assets, achieved 11.6% net-of-fees returns in the first half of 2025. This track record underscores institutional confidence in AQR's systematic, factor-driven investment approach.
The fund's carbon-aware design addresses a critical gap in ESG investing, where many traditional approaches fail to adequately quantify or manage climate transition risks. By explicitly incorporating carbon metrics alongside broader ESG factors, AQR's offering provides institutional investors—including hedge funds, family offices, and pension funds—with a more granular tool for aligning portfolios with sustainability objectives while maintaining active risk management through short positioning.
