"The strength of independence nourishes our collective and responsible commitment. It encourages our agility in the service of an ever more personalized support. It facilitates the application of a demanding and secured code of conduct. More than ever, we are committed to a long-term commitment. Because you and we, in the close relationship of trust that unites us, know that the only value that truly counts is the value of time. »

Emmanuel LAUSSINOTTE, Chairman of Gay-Lussac Gestion

We manage the savings and investments of individual clients, family offices, independent asset managers and institutional investors. A broad client base, but one that we approach with the same philosophy. Our teams give priority to dialogue, listening and the search for dedicated solutions.

We implement an asset allocation focused on risk management, in order to provide our clients with recurring returns, no matter the market conditions. Our active management, in open architecture, is the result of a rigorous methodology and allows us to obtain solid risk/return pairs. 

Our macroeconomic scenarios developed under the direction of a committee chaired by the economist Jean-Pierre Petit, combine quantitative analysis and qualitative filters.

In 2020, we manage more than €1 billion in assets and can count on the loyalty of our investors, which we support according to their needs.
