ACA Group has acquired Global Trading Analytics (GTA), expanding its capabilities in transaction cost analysis (TCA) and best execution support across global financial markets. The move strengthens ACA’s positioning as a provider of technology-enabled governance, risk, and compliance (GRC) solutions, particularly for firms navigating increasingly complex regulatory expectations.
GTA, based in Rutherford, New Jersey, brings with it a long-established reputation in multi-asset class TCA, including equities, fixed income, foreign exchange, futures, and derivatives. Its client base—comprising investment advisers, asset managers, broker-dealers, and wealth managers—will now have access to ACA’s broader suite of compliance and risk solutions. Nearly half of GTA’s clients already work with ACA, offering opportunities for deeper integration.
TCA has grown in importance as regulators continue to scrutinize execution quality. The data-intensive process helps firms measure both explicit and implicit trading costs, allowing them to evaluate broker performance, refine algorithmic strategies, and demonstrate compliance with best execution standards.
Commenting on the rationale behind the deal, ACA CEO Patrick Olson said: “The acquisition of GTA underscores our ongoing commitment to expanding our offerings and equipping our clients with the tools and expertise they need to meet evolving compliance requirements.”
GTA’s leadership sees the transaction as an opportunity to scale while maintaining continuity for existing clients. “Along with my fellow co-founders, Joe Arleo and Clem Cheng, we’re pleased that this partnership ensures our clients will continue to receive the high-touch service they rely on, now strengthened by ACA’s complementary capabilities and broad resources,” said John Halligan, Co-Founder and President of GTA.
The combined offering is expected to deliver enhanced support for firms seeking to reduce trading costs, optimize execution quality, and meet regulatory obligations with confidence.
