RhumbLine Advisers
About
RhumbLine Advisers is a Boston investment firm that manages index-based strategies for institutional investors. Its products range from pure index tracking to enhanced, alternative and customized strategies built around each client’s guidelines. The firm emphasizes passive products tailored to specific needs, close adherence to client guidelines, attentive and personalized service, and a highly competitive fee structure. It serves institutional clients rather than individual retail investors.
Founded in 1990, the firm takes its name from a navigation term: a rhumb line is a straight course drawn on a nautical chart that leads a sailor from one point to another while avoiding hazards. The founders chose it to reflect their goal of helping clients navigate challenging financial waters. More than three decades later, the firm still concentrates entirely on index-based investing for institutions.
