Balázs Székely: Backtestability of Expected Shortfall

The precise definition of backtestability of general risk measures has not been given in the literature yet. In the presentation, we propose a definition which is a natural generalization of Value-at-Risk backtesting. We study the consequences of this new concept on Expected Shortfall backtesting. Finally, we analyze the connection between backtestability and elicitability of risk measures and discover that there is deep connection between them.
