Firm profile

FINTRX

Overview

Neostellar Advisors LLC operates as an institutional registered investment adviser focused on serving institutional clients. The firm charges both a percentage-of-assets under management fee and performance-based fees, indicating arrangements tied to absolute or relative performance rather than flat advisory retainer models. Ownership is listed as a combination of a domestic entity and an individual, and the adviser is not structured as a capital allocator to outside managers. The firm maintains multiple industry roles: it is affiliated with a broker‑dealer, functions as another type of investment adviser, and is involved as a CPO/CTA and as a sponsor, general partner, or managing member of pooled investment vehicles. Neostellar does not list itself as an active ESG investor and is not registered as a multi-state adviser.
