Fund management
Our management philosophy
At the heart of our model lies our ability to identify and exploit investment opportunities. Our team offers investment solutions based on a fundamental business analysis model designed to identify the levers for sustainable growth and reduce volatility, so as to provide you with balanced management between risk and return, whatever the market environment. Our teams are committed to combining performance and sustainable growth.
That’s why we take into account economic, financial and operational factors, while integrating environmental, social and governance (ESG) criteria.

A differentiating management process
Our investment methodology is based on a strict, standardized, four-stage stock selection process:

Quantitative filter
The application of a quantitative filter to the investment universe, based on two defensive criteria (Low Volatility and Low Beta) and one positive performance criterion (Momentum).
