Key Takeaways
- • AQR Capital Management removed five principals from its leadership ranks and closed its struggling long-only fixed-income division, continuing a strategic retrenchment after years of underperformance in systematic trading strategies.

- • Five departing executives include Michael Katz (head of portfolio implementation), Michael Patchen (head of risk), Ari Levine (senior researcher), Scott Richardson (co-head of fixed income research), and Christopher Palazzolo (head of responsible investments), reducing the firm's principal count from 43 to 38.
- • AQR will maintain its long-short, alternative, and risk parity fixed-income strategies despite closing the long-only bond arm that launched in 2014, signaling a return to core systematic trading competencies.
- • The departures follow earlier 2021 news that Ronen Israel, a 22-year veteran and senior principal, stepped down to co-found a biotechnology company.
Summary
AQR Capital Management, the $137 billion quantitative hedge fund manager led by Clifford Asness, announced the removal of five senior principals and the closure of its long-only fixed-income division on November 11, 2021. The moves represent the latest in a series of operational contractions following sustained underperformance across the firm's systematic trading strategies. According to the Financial Times, the five departing principals are Michael Katz (head of portfolio implementation), Michael Patchen (head of risk), Ari Levine (senior researcher), Scott Richardson (co-head of fixed income research), and Christopher Palazzolo (head of responsible investments). The exits will reduce AQR's principal count to 38.
The closure of the long-only fixed-income arm, which commenced operations in 2014, reflects management's strategic focus on the firm's core competencies. However, AQR clarified through partner Suzanne Escousse that the firm will continue systematically trading fixed income through its long-short, alternative, and risk parity strategies—disciplines central to AQR's investment thesis since its inception. The decision to shutter the long-only division while maintaining these alternative approaches underscores the diverging performance between AQR's flagship quantitative strategies and its traditional bond management business.
The personnel reductions and operational restructuring occur against a backdrop of significant asset deterioration. AQR's assets under management peaked at $226 billion in mid-2018 but have since contracted by nearly half to the current $137 billion level. This decline reflects the challenging performance environment for systematic trading strategies over the past three years, as many of the long-standing market signals and factors that underpinned AQR's models faced headwinds. The firm has previously conducted multiple rounds of workforce reductions in response to these pressures. The November 2021 announcements follow the earlier departure of Ronen Israel, a senior principal and 22-year veteran who left to co-found a biotechnology company, indicating continued senior-level departures amid strategic repositioning.
