Xantium Group is a global name for Tudor Capital Europe LLP that runs a multi-strategy, data-driven investment program. It uses teams of quantitative researchers, developers, and traders to build models and trading systems that uncover and exploit opportunities across financial markets. The process centers on quantitative research and technology to identify investment possibilities and navigate market fluctuations, often employing automated or systematic trading across a range of strategies. The group differentiates itself through its integration with Tudor Group, global footprint (London, New York, Stamford, Paris, Singapore, Sydney), and a regulated framework under the Financial Conduct Authority, with leadership led by CEO Oliver Watson and CIO Sergey Levin. Its goal is to generate returns by applying data-driven methods to capture opportunities while managing risk and volatility, without relying on direct client solicitation on its public website.
