Redefining Diversification in the ESG Era

Redefining Diversification in the ESG Era

(Event in English)

Institutional investors are increasingly shifting from broadly diversified equity portfolios to more concentrated portfolios. This trend is driven by the growing importance of ESG integration and exclusion policies. Concentrated portfolios make ESG risk and reputational exposure more manageable. However, this approach may also lead to reduced diversification and higher portfolio risks.

In this seminar, we examine how investors can find the right balance between ESG integration and concentration risk. Are concentrated portfolios the only truly sustainable option, or can a broadly diversified portfolio with extensive ESG integration also meet the ESG ambitions of institutional investors? And how concentrated can a portfolio become before it starts to compromise risk and return?

Presentations from Mathijs van Dijk, Marcel Jeucken and Anne Kock. The event will conclude with a panel discussion with all three speakers.
