About us


We are convinced that, over the medium to long term, equities are the only way of growing investors’ capital.

Globalisation and the standardisation of lifestyles offer the potential for globalised companies to generate strong growth.

We have decided to offer investors a fund invested worldwide in leaders capable of seizing new growth opportunities.
For more risk-averse investors, we offer a customised diversified management service.

We wanted to establish ourselves right in the centre of Europe on an international marketplace. Luxembourg seemed the obvious choice. It meets investors’ need for stability.

What Sets Us Apart

PREVAL is an independent management company directed by passionate entrepreneurial investors who share the same concerns as our clients.

Our interests are aligned with those of our clients : the founders and staff have chosen to invest a significant portion of their savings in the funds managed.

Unlike the large banks, we focus exclusively on asset management. Excellent performance alone will secure your loyalty over time.

You can reach the management team whenever you want.
