FINANCIAL MARKETS
COMPASS
Data is our map. Rules are our compass. Structure is our path.
THE TOPOGRAPHY OF MARKETS
Financial markets are dynamic and often difficult to predict. Like landscapes, they are defined by peaks and valleys, offering opportunities while carrying inherent risks. Just as topography brings structure and orientation to landscapes, systematic models bring clarity to markets. Inspired by the legacy of Swiss topographer Guillaume-Henri Dufour, they help make complex terrain readable.
THE TEAM BEHIND THE APPROACH
Our approach is systematic, but never impersonal. Behind Dufour Capital stands a team with decades of experience in asset management, quantitative analysis, technology, and dedicated client service.

Our History
From its inception to the present day - important milestones in the development of Dufour Capital.
2011 - 2015
Foundation & Start-up Phase
We started with a blank sheet of paper — an empty office and no clients. In return, we had the freedom to develop our systematic concepts and IT infrastructure for asset management entirely from scratch.
2016 - 2020
Partnership with VZ
Strategic partnership with VZ, including intensive joint research and development of rules-based strategies, as well as the publication of textbooks.
2021 - 2026
Institutional and retail clients
Expansion to further institutional partnerships, such as Basler Kantonalbank, family offices, and other asset managers. In parallel, private clients were given access to our institutional solutions — supported by a strong emphasis on personal advice.
