Research Affiliates today announced that it has relaunched as Syzygy Asset Management, an independent, research-led investment firm. The relaunch follows the firm’s sale of its index business, RAFI Indices, to TMX VettaFi.

A syzygy is the alignment of celestial bodies in a straight line, the geometry behind every eclipse. The name reflects the firm’s approach: independent ideas, rigorous research and partnership brought into alignment. It honors more than two decades of research-led investing while marking the start of a new, focused chapter.

Syzygy begins with an experienced leadership team. Rob Arnott serves as chairman, Katy Sherrerd as Chief Executive Officer, and Jim Masturzo as Chief Investment Officer, leading the firm’s investment efforts. Arnott and Sherrerd have worked together for more than 20 years, and Masturzo has been with them for more than 13. The firm will share additional details on its strategies and offerings in the coming weeks.

The sale of RAFI Indices was a strategic decision to place the index business with a partner built to scale it. It allows Syzygy to concentrate fully on active management, the discipline at the firm’s origin, and sets the stage for Syzygy to offer expanded active offerings in the months ahead.

“Research Affiliates was founded on a belief that challenging conventional wisdom can lead to better investment outcomes,” said Katy Sherrerd, Chief Executive Officer of Syzygy Asset Management. “As we look ahead, we’re excited to return to those roots: advancing original research, developing active investment solutions, and serving our clients and partners with the rigor and innovation that have always defined this firm.”

Syzygy also continues its long-standing sub-advisory partnerships with PIMCO and Russell Investments, partnerships that remain central to the firm’s work and are unaffected by the transition.

“For more than two decades, our team has pursued contrarian ideas and, through rigorous research, challenged what many thought they knew about market structure and investor psychology,” said Rob Arnott, Chairman of Syzygy Asset Management. “Syzygy is a deliberate choice to refocus on the active research and portfolio construction that built this firm. We are honoring that legacy as we build toward the next 15 years.”
