Bonds issued by DAX companies in a separate bond index The logic of the RDAX® bond index is based on the market capitalization and liquidity of bonds issued by DAX® companies and the creditworthiness of the issuers.In volatile market phases, many investors prefer attractive and steady performance in the investment, while maintaining low risk. An investment in a bond issued by a well-known company with good creditworthiness and attractive yields meets these requirements. RDAX® provides investors a yardstick with the most attractive bonds issued by DAX® companies. Deutsche Börse is the first index provider to bundle bonds issued by blue-chip index companies in a separate bond index, thereby offering private investors easy and transparent access to the corporate bond market. RDAX® offers numerous advantages for investors and issuers. It provides investors with easy access to bonds issued by DAX® companies. They also profit from the more stable performance compared to equity investments and the more attractive yield compared to government bonds.
