Overview

Partners Advisers SA was set up in Geneva in 1998 as a family office by a family group that began investing in hedge funds in the mid-1980s, and launched a Luxembourg SICAV for co-investors in 2001. A second family group joined its capital in 2013, when the Trendtrust team was consolidated into the firm. It describes itself as the investment arm of the families running the firm and allocates on a multi-manager basis to long-only equity funds, hedge funds, private equity and private credit funds, and selectively to direct private equity and credit deals. It has been authorised by FINMA as a manager of collective investment schemes since 2014.

Investment thesis

Quality risk-adjusted returns through active management and a multi-manager approach, combining bottom-up portfolio construction with macro views to find less market-correlated returns; co-investors invest in the same programme as the founding families.
