Investment strategy

Our investment strategy covers both listed and private assets, comprising specifically Listed Core Investments (LCI), Private Market Investments (PMI), and Liquid Investments (LI).

Listed Core Investments

In LCI we focus on value creation through active ownership in publicly traded companies.

In LCI we seek to invest in attractive companies where we share the mind-set of other significant shareholders and management teams. We target high quality Northern European mid-cap companies, and typically aim at being one the largest owners, working actively through nomination committees and the Board of Directors. A precondition for our LCI investments is that we can articulate an actionable investment thesis which can justify above-market expected returns.

Our current LCI portfolio includes:

Private Market Investments

Within PMI we focus on private market investments on a global basis, covering for instance private equity fund investments and co-investments.

Through PMI we target fund investments within Private Equity, Private Debt, Real Estate, Venture Capital, and Activist Funds. Furthermore, co-investments alongside e.g. Private Equity sponsors, other direct minority investments, and strategic investments such as special vehicles or General Partner stakes, are also at the core of our PMI investment strategy. Our ambition is to be a highly professional, value adding, and flexible Limited Partner and co-investment partner for leading private market sponsors and other stakeholders.

Liquid Investments

LI targets mainly equity- or an equity-like investment exposure.

Investments will by nature be liquid and the investment strategy is global. LI is a complementary investment strategy for Rettig Ltd with the purpose of optimisting the overall risk / return profile in our portfolio.


We always strive to invest in companies with a long-term competitive advantage, and which can justify attractive returns over the cycle. We do not believe that companies can be competitive in the long term, grow, and create value if sustainability is not deeply integrated in their strategies and business decisions. This holds true across all of our sub-strategies: LCI, PMI and LI. We focus our ESG efforts where we believe we can achieve the highest impact. Within LCI, we focus on value creation in listed companies through active ownership. These investments are typically the ones where our ability to directly influence companies’ sustainability agendas is the highest.
