About
Avior Capital Markets US, LLC provides research distribution and trade facilitation services to U.S. institutional clients — including investment advisers, broker-dealers, hedge funds and registered funds — by acting as a chaperone under SEC Rule 15a-6 to affiliated foreign broker-dealers. The firm is dually registered as a FINRA broker-dealer and as a New York state-registered investment adviser to support distribution of hard‑dollar research and agency execution of foreign securities.
Avior does not provide portfolio management for individual clients, does not custody client assets, and does not charge percentage‑of‑AUM or performance‑based fees; instead it is compensated through hard‑dollar research fees and a share of commission fees generated under its chaperone agreements. The firm does not prepare or endorse the research it distributes, does not exercise investment discretion for client accounts, and does not conduct periodic account reviews typical of advisory firms that manage client portfolios.
Compared with peers, Avior’s model is characterized by its broker‑dealer activity and formal affiliations with foreign affiliates (including UK and South African entities) that produce and distribute research under chaperone agreements, a structure that led it to register as an adviser after the SEC’s no‑action relief expired. The brochure also discloses a cost‑plus arrangement in which foreign affiliates reimburse the firm’s expenses plus a markup, and the firm serves only institutional clients rather than retail or individual (including high‑net‑worth) investors.

Not sure where to start?
We'll help you think it through—whether you ultimately need an advisor or not. Warmer helps you compare advisors clearly, so you can choose with confidence.
For advisor listings, we rely on sources including public filings and data provided by advisors, and we cannot guarantee that all information is current or accurate. Advisors are independent and may not have reviewed or updated this information. Please review an advisor’s Form ADV and do your own diligence before deciding whether to work with them.
Advisor matching and introductions are provided by FinanceHQ LLC (“FHQ”), a wholly-owned subsidiary of Warmer and an SEC-registered investment advisor. We receive compensation from certain participating advisors for introductions or referrals. This creates a conflict of interest because we have an incentive to recommend advisors who compensate us, including those who pay us more. You pay no fee to use our matching service, and advisor fees are not increased because of a referral or introduction. We do not review the ongoing performance of advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.
By using our service, you agree to our Terms of Service and Advisory Agreement, and acknowledge our Privacy Policy. Please review FHQ’s ADV Part 2A and Form CRS. Logos provided by Logo.dev
