In summary, trading with ETNs and ETCs like ETF trading on Xetra and the Frankfurt floor is transparent, fast, inexpensive and with permanent buying and selling opportunities. But: Since the funds invested in ETCs and ETNs are not part of the issuers' special assets, unsecured products are associated with the risk of debtor default. In return, the construction of ETCs and ETNs makes it possible to participate in the performance of commodities, more exotic securities and other market indicators. An exposure to stock market volatility, for example, has not been possible via ETFs to date.
