DKO Renten USD aims to achieve long-term returns in US dollars by investing mainly in a diverse array of international fixed and variable interest securities. This includes traditional bonds that provide regular interest income, bonds with additional features like convertibility or options, and zero-coupon bonds that are sold at a discount and redeemed at their full value. The fund does not restrict investments based on the credit quality or location of the issuers and may also hold some liquid assets and small positions in other funds to enhance its portfolio.
