The Company

Allaria Securities LLC is the U.S. broker-dealer affiliate of the Allaria Group, an independent financial services organization with roots in Argentina dating back to 1968. Founded in Buenos Aires by Ernesto Allaria Ledesma, the group has grown over the decades into an established financial platform serving retail, institutional, and cross-border clients.

Established in Florida in 2016 and operating from Miami since approximately 2018, Allaria Securities LLC reflects the group’s broader international expansion and longstanding commitment to serving clients with a global perspective. Together with its affiliated U.S. investment adviser, Allaria Asset Management LLC, the firm forms part of Allaria’s U.S. presence while remaining distinct in its regulatory role and service offering.

As a U.S. registered broker-dealer and member of FINRA and SIPC, Allaria Securities LLC provides brokerage, execution, and related securities services to retail and institutional clients. The firm operates within a disciplined regulatory framework and is supported by clearing and custody services provided through Pershing LLC, a subsidiary of The Bank of New York Mellon Corporation.

Our Heritage

The Allaria Group traces its heritage to the founding of its original Argentine brokerage business in 1968. Over time, the group expanded beyond traditional brokerage into broader financial and capital markets capabilities, while maintaining an independent ownership structure and a reputation built on long-term relationships, market experience, and regional insight.

Today, the group maintains a presence across multiple jurisdictions, including Argentina, the United States, Uruguay, and Panama. This cross-border platform is designed to support clients with international needs while operating within the regulatory frameworks applicable in each jurisdiction.

The broader Allaria platform is defined by its familiarity with Latin American markets, its cross-border client base, and a service model centered on tailored solutions, experienced leadership, and personalized attention. In Miami, that positioning is complemented by the stability and investor protections associated with a U.S. regulated framework.
