Recent literature has proposed new methods for measuring the systemic risk of financial institutions based on observed stock returns. In this paper we examine the reliability and robustness of such risk measures, focusing on CoVaR, marginal expected shortfall, and option-based tail risk...

For both linear and non-linear return frameworks, assuming normal and heavy-tailed distributions, we identify non-exotic cases in which a change in a bank's systematic risk, idiosyncratic risk, size or...
