Qube Research names Holly Lau US COO to expand market-making

Qube Research & Technologies has appointed Holly Lau as its US chief operating officer. Lau, who is based in New York, joins the quantitative firm after eight years at Citadel Securities and a recent chief operating officer role at Summit Securities.

At Citadel Securities, Lau held senior trading roles including head of delta one and American depositary receipt trading. She left Citadel in 2024 and most recently served as COO at Summit, a New York proprietary trading and market-making firm.

In her new role, Lau will oversee operational functions that support Qube’s trading and market-making activities across the United States, including trading operations, technology infrastructure and market-access services.

Qube, which is headquartered in the UK and France, has expanded its North American presence since last year and now operates in several US locations, including New York and Chicago. The firm also runs a separate commodities trading unit, Q-TX, based in Houston.

The firm has increased its use of electronic market-making strategies and reported returns of about 30% last year. Qube is hiring across its US platform, with open roles in New York for engineering and trading infrastructure, including FPGA engineers and C++ developers focused on crypto-related systems. Additional positions are available in Chicago and within the Houston-based commodities business.
